Advantages and disadvantages of low cost housing

Sr. No.AdvantagesDisadvantages
i)Economic Benefits to the Community – Affordable housing provides direct economic advantages to the immediate community. Since the houses are affordable, people will have extra money to spend for other products. This is going to lead to an increase in the demand of various services and goods further leading to increased employment opportunitiesThe low cast housing will not satisfy all the needs of the people.
ii)Provides a diverse workforce – The best thing about affordable housing is the fact that it accommodates individuals with different skills that are beneficial to the community. For instance, construction workers, bus drivers, cleaners, shop assistants, teachers and nurses are well catered under affordable housing and thus they can provide their important services to the community.The residents have limited money so there will be less likely to improve or maintain their homes or the surrounding environments.
iii)Promotes social and economic integration – Affordable housing ensures low cost housing due to which such families can afford to meet their respective health and education costs. This is also beneficial as it provides an adequate security of tenure for improving an individual’s capacity to get and also maintain employment. In addition to that, affordable housing enables people not to migrate from their root place.Houses have a simple layout that may or may not have living area separate from a sleeping area and large family inhabit will probably cram 2 people per bedroom and 3 in the living room and make the space over crowded.
iv)Stronger labour force – Through affordable housing, the employees will live near their respective employment centers and this leads to a stronger labour force. The work is also going to be done quickly since the people livingin the immediate vicinity and can go to work quickly.There will be no choice or control of public type to reside near or adjoin as your neighbors.
