The Government is proposing modification of state enactments and city level master plans for upward revision of FAR/FSI to accommodate land allocation for LIGs.
Tremendous economics is involved in the process of the mass housing schemes. An overview is needed to be taken to reduce the construction costs and make these constructions affordable which can be done on several levels .The review areas include economising construction materials costs, proper usage of technologies-conventional and alternate and project management. Several Developers are adapting these methods to reduce the construction costs of their projects.. It is estimated that overall employment generation in the economy on account of additional investment in the Construction/Housing Sectors is eight times the direct employment (IIM Ahmedabad : 2005). In view of the substantial use of cement, steel, marble/ceramic tiles, electrical wiring, PVC pipes and various types of fittings; construction activity has a multiplier effect on industrial demand for these items.

  • Housing Scenario and Urbanization : India1. India is undergoing transition from rural to urban society.2. Increasing migration from rural to urban areas.3. Mismatch between demand and supply of sites and services.4. Disparity between high land costs of construction and lower incomes leading to non sustainable situation.5.Lack of equitable supply of land, shelter and services at affordable prices.6. Depletion of resources in construction and negligence of ecology in design.7. Lack of application of cost effectiveness and energy efficiency in construction.
  • Housing Scenario and Urbanization : India1.28% urban population growth (Census 2001).2.40% by 2020 (Vision 2020 – Planning Commission).3. 50% by 2041 (draft Urban India Report).4.Growing urbanisation has led to :a) pressure on the availability of land and infrastructureb) deterioration of housing conditions of the weaker sections of societyc) increased number of slums and squatter settlements.
  • Necessity of Providing Affordable housing1.Urban population likely to grow from 285.3 million in 2001 to 360 million in 20102.Nearly 36% of India’s population likely to be urbanised by 2005.3.Employment in Rise in population in last ten years services and real is 790.2 millions S0urce-Registrar General Of India estates show a sharp rise.

  • Public Private PartnershipPartnership Expectations1.Timely delivery by developers2.Ease of working by the government3.Transparency by both the parties
  • Public And Private Partnership in Affordable housingThe public-private partnership can be formally definedas:In these partnerships, private developers, non-profit agencies, andin some cases religious agencies receive some funds or supportfrom the municipal, state, or federal government (or all three, insome cases) in order to build or renovate and manage affordablehousing. This can be used both for rental housing and as a meansof encouraging low-income home ownership. This is also anapproach that has been used in a number of other countries.A contractual relationship where a private party takesresponsibility for all or part of a government’s (departments)functions… a contractual arrangement between a public sectoragency and a private sector concern, whereby resources and risksare shared for the purposes of delivering a public service or fordeveloping public infrastructure. (Hardcastle & Boothroyd, 2003, p.31).
  • The Scheme of Affordable Housing in Partnership as per NationalUrban Housing & Habitat Policy (NUHHP) 20071.The Scheme of Affordable Housing in Partnership aims atoperationalising the strategy envisaged in the National UrbanHousing & Habitat Policy (NUHHP) 2007,of promoting various types of public-private partnerships – of thegovernment sector with the private sector, the cooperative sector,the financial services sector, the state parastatals, urban localbodies, etc. – for realizing the goal of affordable housing for all.2. It intends to provide a major stimulus to economic activitiesthrough affordable housing for the creation of employment,especially for the construction workers and other urban poor whoare likely to be amongst the most vulnerable groups in recession. Italso targets the creation of demand for a large variety of industrialgoods through the multiplier effect of housing on other economicactivities.
  • Need for PPP in Housing1.Synergy2.Capitalize and maximise on core domain of respectiveplayers3.Scale of Development4.Humongous need for combined capabilities5.Investment Gap Funding6.Cost spread over project lifecycle in PPP model ratherthan being front loaded in traditional procurement model7.Improving Quality &Efficiency8.Returns for private players linked directly toefficiency and quality delivery9.Risk Mitigation10Appropriate allocation between stakeholders11On-Time Delivery12Faster and time approvals, payments also linked totimely completion
  • Philosophy For Recommended modelsSource-Mr Gulam Zia_Knight Frank.
  • Role OF National Housing Bank Towards Affordable Housin Some Basic Facts Regarding Construction Industry. 1.A basic human necessity supporting economic activities . 2.Second largest employment generator, next to agriculture. 3.Has forward and backward linkages with over 250 ancillary industries. 4.Every Rupee spent on construction, an estimated 75-80 paise is added to GDP. 5.GOI created enabling Fiscal, Monetary and Legal Environment 6.Housing Industry Growth in last 5 years – Physical Terms 3.0 % p.a. Financial Terms 30% p.a. 7.Contribution of Housing in GDP is about 6% 8.Percentage of Mortgage Debt to GDP is 8.50% (E) in 2005-06, still way below China’s (12%), Malaysia (22%), Hong-Kong (40%) and US (65%).
