Introduction

The concept of High Density High Rise Vertical Living for Low Income People refers to designing, developing, and managing tall residential buildings (high-rise) where many housing units are vertically stacked, aimed specifically at affordable or low income populations. The idea emerges out of pressures from rapid urbanization, land scarcity, rising land values, infrastructure deficits, and the urgent need to provide housing for the urban poor in sustainable, efficient, and equitable ways.

This summary explores the case for High Density High Rise Vertical Living for Low Income People: its rationale, design and planning considerations, benefits, challenges, management models, case studies, financing, policy implications, and recommendations for implementation. It examines how such housing can contribute to social justice, urban efficiency, environmental sustainability, and economic viability, while maintaining affordability and dignity for low income residents.

The Colombo Master Plan (2008) reveals that there are 66,000 households within the City of Colombo living in squalid slums and shanties unfit for human habitation. They represent 51 percent of the total city population and live in 1,506 pockets of human concentration identified as Under-Served Settlements (USS) encumbering on state-owned lands with no title. About 390 hectares of valuable prime lands in the City have succumbed to the encroachment process during the past five decades. Moreover, they have engulfed all the environmentally sensitive low-lying areas, canal banks, and flood retention areas as well as roads, railway reservations and other open spaces. Since gaining independence in 1948, the Sri Lankan government has devoted much attention to finding a solution for this situation and has successively introduced policies, programs and projects to overcome poor housing in Colombo. However, most of these programs have proven to be only temporary fixes, and have not made any significant long-term impact to the housing sector overall. This research paper discusses the Sri Lankan government’s policy move towards high-rise high-density low income public housing as an appropriate solution for slums and shanties in Colombo City. It is noted that high-rise housing for low-income people is not a universally accepted solution for housing low-income people and some countries have totally rejected high-rise for low-income housing due to significant failures in the past. At the same time, some other countries claim success in high-rise housing for low-income people including uplifting low-income people to a middle-income status through high-rise housing. Therefore high-rise low-income housing remains a controversial topic in many developed and developing countries. This paper revisits the literature on Pruitt-Igoe in order to identify lessons that may assist Sri Lankan authorities to avoid similar failures.

Rationale for High Density High Rise Vertical Living for Low Income People

Land Scarcity and Rising Land Costs
In many cities, particularly in emerging economies, land in central or near-central areas is scarce and expensive. Horizontal expansion (sprawl) becomes costly both in terms of land and infrastructure extension. Thus High Density High Rise Vertical Living for Low Income People offers a way to house many people on less land, making efficient use of constrained land resources.
Economies of Infrastructure and Service Provision
When many units are stacked vertically, infrastructure (roads, water mains, sewage, electricity) can be shared and centralized, lowering per unit cost. Vertical living lends itself to economies of scale in utilities, maintenance, and services. High Density High Rise Vertical Living for Low Income People thus can reduce costs of servicing compared to dispersed low-density housing.
Proximity to Jobs & Amenities
High density high rise projects, when located near transit, employment centers, markets, and social infrastructure, reduce commute times and travel costs. For low income people, High Density High Rise Vertical Living for Low Income People in well-connected locations is more equitable and has higher impact.
