Planning, Infrastructure and Design
Introduction
Health Sub-Centres form an important part of India’s primary healthcare network. Located close to the communities they serve, these facilities support preventive healthcare, health education, maternal and child health services, screening, basic treatment, follow-up and referral.
For architects and healthcare planners, designing a Health Sub-Centre involves more than arranging a few consultation rooms. The building must support the intended range of services, maintain patient privacy, provide appropriate sanitation and handwashing facilities, enable accessible movement and accommodate healthcare workers’ operational needs.
The Indian Public Health Standards (IPHS) 2022 — Health and Wellness Centre–Sub Health Centre (HWC-SHC) document is the key national reference for understanding the expected service provision, infrastructure, staffing, equipment and quality benchmarks for these facilities. It was published by the Ministry of Health and Family Welfare, Government of India.

This guide explains how architects can interpret those standards during site selection, concept planning, drawing preparation, refurbishment and facility assessment.
What are the IPHS guidelines for Health Sub-Centres?
The Indian Public Health Standards are national benchmarks intended to improve the availability, quality and consistency of services at public healthcare facilities. The standards cover matters such as infrastructure, staffing, essential medicines, diagnostics, equipment, service delivery and quality assurance.
National Health Mission

For a Health and Wellness Centre–Sub Health Centre, IPHS 2022 provides a framework that healthcare authorities and design teams can use to assess whether a facility has the infrastructure and resources needed for its intended services.
The official document also includes illustrative layouts for different facility configurations, including options with or without a labour room and residential accommodation, as well as a new-construction layout. These are valuable references for preliminary architectural planning, although they should not be treated as universally applicable, ready-to-build drawings.

1. Background and evolution of IPHS
The Ministry of Health and Family Welfare developed IPHS as a common reference for public healthcare infrastructure and service delivery. The original standards were published in 2007, followed by revisions, including the 2022 guidelines. The latest revision incorporated newer healthcare initiatives and the evolving role of Health and Wellness Centres.
Clinical Establishments

The change is important for architects because a modern HWC-SHC is not simply a conventional rural dispensary. Its planning should support a broader primary healthcare model, including wellness activities, screening and follow-up, health education and community-oriented services.
Why the 2022 edition matters
- It provides the current national reference identified by the Ministry for HWC-SHC infrastructure and service provision.
- It distinguishes essential standards from desirable improvements.
- It includes guidance on infrastructure, human resources, medicines, diagnostics, equipment, quality assurance and implementation.
- Its annexures provide illustrative floor plans and supporting operational material.
National Health Mission+1
Architects should therefore avoid relying exclusively on older sub-centre guidelines when developing new proposals or reviewing existing facilities.
2. Population norms and service coverage
Population coverage influences the location, accessibility and workload of a primary healthcare facility. The commonly cited rural norms for Sub Health Centres are one facility for every 5,000 people in plain areas and every 3,000 people in hilly and tribal areas. The Government of India’s published explanation of these norms also identifies 20,000 people for a rural PHC in hilly and tribal areas and 30,000 in plains.
Press Information Bureau

These figures provide a useful planning starting point, but a project team should verify the applicable category, population norm and any local adjustments in the current IPHS document and state implementation instructions.
| Planning factor | Architectural significance |
|---|---|
| Catchment population | Helps establish expected demand and service capacity. |
| Settlement distribution | Influences travel distances and the choice of site. |
| Terrain and climate | Affect pedestrian access, drainage, shading and building orientation. |
| Existing health facilities | Influence referral routes and the distribution of services. |
| Outreach workload | Determines how staff, records, equipment and supplies are managed. |
| Future population growth | Helps assess adaptability and potential expansion. |
Architectural interpretation: A facility serving dispersed settlements may need better external access, sheltered waiting and convenient staff access for outreach work. A compact facility in a denser settlement may place greater emphasis on efficient circulation and managing peak waiting demand.
These are design considerations, not substitutes for the official population norms.
3. Types of Health and Wellness Centre–Sub Health Centres
The IPHS 2022 document contains several facility configurations. Its annexures include layouts for facilities with and without a labour room, with and without residential accommodation, and a new-construction option.
National Health Mission
+2
The correct configuration should follow the intended clinical services, staffing and operational requirements.
| Facility configuration | Key planning implication |
|---|---|
| HWC-SHC without labour room | Prioritise consultation, examination, wellness, waiting, records and other required services. |
| HWC-SHC with labour room | Plan for the additional clinical space, equipment, privacy, hygiene and support functions needed for delivery services. |
| Facility with residential accommodation | Separate domestic and staff living functions appropriately from patient-facing clinical areas. |
| New-construction facility | Coordinate the complete site layout, building services, accessibility, circulation and future adaptability from the outset. |
Do not select a configuration based only on plot size or a standard drawing. Confirm the facility’s approved scope of services before fixing the architectural brief.
4. Infrastructure requirements for HWC-SHC
IPHS 2022 addresses infrastructure alongside service delivery, staffing, equipment and quality requirements. The document includes specific sections on infrastructure, general appearance and upkeep, safety, illumination, water and sanitation, power backup and emergency preparedness.
National Health Mission
For architectural planning, these requirements should be translated into coordinated drawings, room schedules and specifications.
4.1 Site selection and access
A suitable site should be assessed for:
- Safe and convenient access from the communities served.
- Connection to a usable approach road or pedestrian route.
- Emergency access appropriate to the services provided.
- Reliable water, electricity and communications where available.
- Site drainage and protection from flooding or waterlogging.
- Safe access for people with disabilities, older adults and people with limited mobility.
- Potential for future changes without obstructing existing circulation.
The site should be evaluated in its local context. A design suitable for a compact urban settlement may not work on a remote rural site with dispersed villages, difficult terrain or limited infrastructure.
4.2 Building entrance and reception
The entrance should be easy to identify from the approach route. Users should be able to understand where to register, wait and proceed for consultation without repeatedly asking staff for directions.
Architectural provisions to consider include:
- A clear, step-free accessible route wherever feasible and as required by applicable standards.
- A sheltered entrance and waiting area.
- Appropriate lighting and visible signage.
- A logical relationship between reception, waiting and consultation.
- Space for accompanying family members where appropriate.
- Protection from rain, excessive sun, dust and heat.
Avoid locating the entrance so that patients must pass through clinical or staff-only areas to reach reception.
4.3 Consultation and examination
Consultation areas should support confidential conversations, clinical examination, hand hygiene and convenient access to required equipment.
The layout should account for:
- Privacy at doors, windows and examination positions.
- Appropriate examination lighting.
- Handwashing and infection-prevention provisions.
- Furniture clearances and accessible movement.
- Storage for records, consumables and clinical supplies.
- Acoustic separation from crowded waiting areas.
Privacy is a functional requirement, not merely an interior-design preference. A consultation room may be large enough on paper but still perform poorly if its door opens directly towards a crowded public waiting area.
4.4 Wellness and health-education space
Health education, counselling and wellness activities form part of the broader primary healthcare approach. The planning brief should clarify which activities will occur in the facility and how frequently they will be conducted.
Where a dedicated wellness space is provided, consider flexible furniture, adequate lighting, ventilation, accessible circulation and the ability to accommodate group activities. Do not assume that a particular room size is mandatory without checking the applicable official schedule.
4.5 Toilets and sanitation
Toilets should be easy to locate, accessible to the intended users and positioned so that their operation does not compromise clinical hygiene or privacy.
The design team should verify applicable requirements for:
- User accessibility and sanitary fixtures.
- Water supply and handwashing.
- Drainage and wastewater disposal.
- Cleaning access and maintenance.
- Ventilation and odour control.
- Separation of clean and contaminated activities where relevant.
Actual fixture counts, dimensions and accessibility provisions must be checked against the applicable IPHS, accessibility, plumbing and local building requirements.
4.6 Water, electricity and building services
Reliable building services are essential to the functioning of a healthcare facility. The design should coordinate electrical distribution, lighting, ventilation, water supply, drainage, communications and backup arrangements with the facility’s approved services.
Consider:
- Adequate lighting for consultation, examination and circulation.
- Appropriate ventilation and thermal comfort.
- Reliable water for hand hygiene, cleaning and sanitation.
- Protected electrical distribution and sufficient socket provision.
- Backup power for services identified as critical.
- Maintainable plumbing and electrical routes.
- Safe placement of equipment and service access points.
A coordinated MEP design reduces the risk of late changes to clinical rooms, ceiling layouts and plumbing routes.
4.7 Biomedical waste and infection prevention
Clinical waste must be managed according to applicable biomedical waste rules and current healthcare protocols. The architectural layout should support segregation at the point of generation, safe temporary handling, cleaning and authorised removal.
Provide suitable locations and access for the waste-management system defined by the operating authority. Do not use a generic refuse store as a substitute for a properly planned clinical waste arrangement.
5. Architectural planning and functional zoning
The most useful architectural approach is to organise the facility by function, privacy and the movement of people and materials.
The following is a conceptual planning framework, not an official IPHS-mandated adjacency diagram.
Illustrative functional zoning

Entrance · Registration · Waiting
CONSULTATION ZONE

Conceptual flow for design development. The actual arrangement depends on the approved service package and facility configuration.
5.1 Public and clinical circulation
Patients should be able to reach reception and the relevant service rooms through a clear route. Staff should be able to carry out their duties without unnecessary interruptions, and supplies and waste should be handled in ways that minimise conflicts with public movement.
Map the routes of:
- Patients arriving for routine consultation.
- Pregnant women, infants and caregivers.
- People attending group wellness activities.
- Healthcare workers leaving for outreach services.
- Supplies, cleaning equipment and clinical waste.
The objective is not to create unnecessary corridors. It is to provide safe, understandable movement while protecting privacy and hygiene.
5.2 Privacy and dignity
Privacy should be assessed from the user’s point of view. Consider sightlines from entrances, windows, waiting areas and external circulation routes.
Use door positioning, screens, suitable glazing, acoustic treatment and internal zoning where appropriate. Avoid relying on curtains alone where the intended service requires more robust visual or acoustic privacy.
5.3 Flexibility and future adaptability
A small health centre may need to accommodate new programmes, equipment or changes in service delivery over time.
A flexible layout can include appropriately located power and data points, accessible service routes, practical storage and spaces that can accommodate more than one compatible activity. Changes must not compromise infection control, accessibility or the facility’s approved clinical functions.
6. Understanding the official IPHS 2022 layout drawings
The official guideline provides illustrative floor plans that can help design teams understand how required functions may be accommodated. Two examples demonstrate why the intended facility configuration matters.
Example 1: HWC-SHC with a labour room
The official PDF includes a layout titled “HWC-SHC with Labour Room and without Residential Facility,” illustrating how delivery-related functions are accommodated alongside consultation, wellness and support spaces.
National Health Mission
Architectural lesson: The labour room affects the functional brief, equipment requirements and relationships between clinical spaces. It should not be added to a plan without reviewing its complete support needs.
Example 2: HWC-SHC new construction
The official new-construction illustration identifies a built-up area of approximately 350 m² (3,786 ft²). This is an area shown for that particular example, not a universal minimum or maximum for every HWC-SHC.
National Health Mission
Architectural lesson: Use the drawing as a reference for functional relationships, then develop a project-specific plan based on the approved brief, site constraints and applicable standards.
How to use a standard layout correctly
- Confirm that the drawing corresponds to the intended facility category.
- Check whether it includes a labour room or residential accommodation.
- Verify room labels, dimensions and notes directly in the source PDF.
- Review the drawing against the actual site and access conditions.
- Coordinate structure, electrical, plumbing, ventilation and drainage.
- Verify applicable accessibility, fire safety and local approval requirements.
- Record all departures from the reference plan and their reasons.
A standard layout is a planning aid. It does not automatically establish compliance for a different site or project.
7. Room planning and architectural schedule
A room schedule helps connect the clinical brief to the floor plan. The following table is a design-development checklist, not a substitute for the official room or infrastructure schedule.
| Functional space | Main purpose | Key planning considerations |
|---|---|---|
| Entrance and reception | Direct users to services | Visibility, signage, accessibility |
| Waiting area | Accommodate patients and caregivers | Seating, shade, ventilation, circulation |
| Consultation room | Clinical consultation | Privacy, lighting, equipment, hand hygiene |
| Examination area | Clinical assessment | Patient dignity, furniture clearances, cleaning |
| Wellness space | Education, counselling or group activities | Flexibility, accessible movement |
| Laboratory or diagnostic space, where required | Specified tests and related activities | Equipment, work surfaces, hand hygiene, storage |
| Maternal and child health space, as required | Relevant maternal and child health services | Privacy, equipment, patient flow |
| Labour room, where applicable | Delivery-related services | Clinical requirements, hygiene, support functions |
| Records and storage | Manage documents and supplies | Secure storage, convenient staff access |
| Toilets | Sanitation for users and staff | Accessibility, ventilation, drainage |
| Cleaning and waste-management provision | Support hygiene and safe waste handling | Segregation, secure handling, service access |
| Staff support or residential space, where required | Staff work and accommodation | Separation from public circulation |
The actual room list should be derived from the relevant IPHS 2022 requirements and the approved scope of services. Not every facility configuration requires every space listed above.
Room data sheets and coordination
Before preparing detailed architectural drawings, develop room data sheets for the required spaces. Each sheet should identify, as applicable:
- Room function and intended occupancy.
- Required furniture and clinical equipment.
- Door and circulation requirements.
- Lighting, ventilation and thermal-comfort needs.
- Water supply and drainage requirements.
- Electrical, communication and data provisions.
- Finishes and cleaning requirements.
- Privacy and infection-prevention measures.
- Storage, maintenance and access requirements.
This approach also supports coordination with structural and MEP consultants by establishing service requirements before drawings are finalised.
8. Accessibility and inclusive design
A community health facility must be usable by people with different physical abilities, ages and mobility requirements.
The design team should check the applicable Indian accessibility standards and regulations rather than relying on informal assumptions about minimum dimensions.
Important design considerations
- A continuous accessible route from the site entrance to the principal service areas.
- Step-free access or compliant ramps and level changes where required.
- Door clearances and circulation space suitable for intended users.
- Accessible toilet provisions where required.
- Appropriate handrails, signage and visual contrast.
- Seating for older adults, pregnant women and people who cannot stand for long periods.
- Safe walking surfaces and effective drainage.
- Clear wayfinding for people unfamiliar with the building.
Design recommendation: Assess the complete journey from the approach road to the consultation room, not just the entrance ramp. A nominally accessible entrance is insufficient if internal thresholds, narrow routes or inaccessible toilets prevent independent use.
9. Climate-responsive design for rural healthcare facilities
India’s climatic conditions vary significantly. A Health Sub-Centre in a hot-dry region requires a different response from one in a humid, high-rainfall or cold region.
Climate-responsive strategies should complement the clinical and operational requirements rather than override them.
| Design factor | Possible design response |
|---|---|
| High solar exposure | External shading, appropriate orientation and suitable roof insulation |
| Hot weather | Solar control, ventilation and efficient cooling where needed |
| Heavy rainfall | Site drainage, protected entrances and weather-resistant detailing |
| Humid conditions | Moisture control, ventilation and suitable material specifications |
| Dust | Manageable entrances, appropriate openings and practical cleaning strategies |
| Power interruptions | Planned backup for services identified as essential |
| Water scarcity | Efficient fixtures and a dependable, maintainable water-supply strategy |
These are general architectural recommendations, not a list of mandatory IPHS clauses. Verify project-specific requirements, including ventilation for clinical functions, in the applicable technical documents.
Landscape and external areas
Landscape design can improve shade, comfort and the usability of outdoor waiting spaces. However, planting should not obstruct accessible routes, emergency access, signage or service areas.
Use planting and surface treatments suited to local maintenance capacity and water availability. Avoid creating waterlogged areas, uncontrolled vegetation or places that complicate pest management.
10. Structure, materials and construction
Material selection should respond to durability, cleaning, local availability, maintenance and climate.
Walls and finishes
Specify finishes suitable for the function of each space. Clinical and sanitation areas may need more frequent cleaning and more moisture-resistant finishes than ordinary administrative spaces.
Flooring
Floors should be stable, cleanable and appropriate for the anticipated movement of patients, equipment and staff. Select slip-resistant finishes where necessary, while ensuring that the surface remains suitable for wheeled mobility and cleaning.
Doors and windows
Door locations should preserve privacy and avoid obstructing movement. Window placement should consider daylight, glare, ventilation, external privacy and climatic exposure.
Roof and envelope
Roof and wall assemblies should provide appropriate weather protection, thermal performance and maintainability. In areas exposed to heavy rain or extreme heat, detailing and insulation can have a major effect on the facility’s usability.
Structural and MEP coordination
Coordinate structural framing with clinical room layouts, plumbing routes, electrical services and required equipment. Avoid unplanned penetrations through beams or structural elements. Service openings and embedded items should be agreed with the structural engineer before construction.
11. Fire safety, emergency preparedness and operational resilience
IPHS 2022 includes material on safety, disaster preparedness and emergency arrangements.
National Health Mission The architect should coordinate these considerations with applicable building and fire regulations.
Review the following:
- Safe entrance and exit arrangements.
- Emergency access and the movement of people with reduced mobility.
- Suitable electrical protection and equipment placement.
- Emergency lighting and backup provisions where required.
- Clear circulation routes without storage obstructions.
- Safe storage of supplies and clinical materials.
- Site drainage and protection from relevant local hazards.
- Emergency procedures appropriate to the services delivered.
The exact fire protection and evacuation requirements depend on the building, occupancy, local regulations and competent authority’s requirements. Do not assume that the provisions for a small outpatient facility automatically apply to a facility with additional clinical functions.
12. Common mistakes in Health Sub-Centre design
Using an outdated guideline without checking revisions
An older article or plan may not reflect the 2022 HWC-SHC framework. Confirm the applicable version before developing the brief.
Treating an illustrative floor plan as a mandatory prototype
Standard plans are references. Project-specific site conditions, the approved scope and local requirements still need assessment.
Adding rooms without planning the workflow
A list of rooms does not guarantee good planning. Check how patients, staff, supplies and waste move through the building.
Ignoring privacy and accessibility
Consultation rooms, waiting areas and toilets must work for actual users, including people with disabilities and those needing additional privacy.
Leaving MEP coordination until late in the project
Late coordination can create avoidable changes to clinical rooms, ceilings, equipment positions and service routes.
Confusing a design recommendation with a formal requirement
Every mandatory dimension, equipment provision or statutory requirement should be traceable to its applicable source.
13. Practical IPHS compliance checklist for architects

Tick each item only after verifying the corresponding requirement or drawing. Completing this checklist does not certify statutory or IPHS compliance.
14. How to use IPHS guidelines during project development
A systematic workflow helps avoid omissions and unnecessary redesign.
- Review the official guideline. Identify the sections applicable to the facility category and intended services.
- Prepare the project brief. Confirm the scope with the healthcare authority or client.
- Assess the site. Check access, climate, drainage, utilities and nearby referral facilities.
- Develop the functional schedule. Identify rooms, equipment, adjacencies and support functions.
- Prepare concept options. Compare alternative arrangements for patient movement, privacy and expansion.
- Coordinate consultants. Integrate structural, electrical, plumbing, ventilation and other relevant services.
- Check compliance. Trace technical decisions to the applicable guideline, code or approval requirement.
- Review the completed facility. Check that the built environment supports the intended services and operational procedures.
Conclusion
IPHS guidelines provide a national framework for planning and assessing public healthcare facilities, including Health and Wellness Centres–Sub Health Centres. The 2022 HWC-SHC document should be the starting point for architects reviewing current requirements.
A successful design translates these standards into a practical, accessible and maintainable building. Clear circulation, patient privacy, suitable clinical spaces, coordinated building services, infection prevention and climate-responsive design all contribute to that outcome.
For professional projects, always verify dimensions, mandatory provisions and compliance criteria in the official guideline and applicable state and local regulations. A well-designed Health Sub-Centre is not simply a compliant floor plan; it is a facility that can reliably support the community and healthcare team throughout its operational life.
