Central Core Housing With Flexible Offset Units

Project in-detail

The design focuses on central core access and flexible offset units to enhance natural light and ventilation, creating adaptable housing solutions in a high-density urban environment.
5 key facts about this project
01
Central core design facilitates improved resident interaction and accessibility.
02
Unique offset unit arrangement enhances natural light and ventilation.
03
Modular housing blocks allow for both vertical and horizontal expansion.
04
High-density urban integration maximizes site utility and service access.
05
Sustainability features support energy efficiency and thermal comfort.

The HORVEX housing project addresses the pressing housing needs in London, focusing on finding practical solutions in a city with limited available space. Located in Inner London, the project aims to offer flexible living environments designed to adapt to various needs and configurations. The overall concept emphasizes modular blocks that can be expanded both upwards and outwards, making efficient use of the urban landscape.

Design Concept

The HORVEX design features compact blocks, each measuring 13.5m by 16.5m. This size allows for configurations that can accommodate at least two and up to four housing units per block. The central access core encourages residents to engage with one another, promoting a sense of community within the building. This layout also enhances the flow of light and air throughout the units.

Extension Capabilities

The arrangement of the blocks allows for both horizontal and vertical expansion. In horizontal layouts, the blocks are offset, which helps to maximize natural light and ventilation for the lower units. This also leaves room for parking, which is an important consideration in urban design. For vertical growth, the uniform layout of utilities simplifies construction and maintenance, making it easier for future developments to be integrated.

Site Context

The chosen sites are Studley Road in Stockwell and a corner at Besson Street and Brian Street. These locations are part of a high-density area in London, making them ideal for this housing solution. The access to existing transport links and amenities will help residents enjoy a better quality of life. Integrating these units into the surrounding urban environment will strengthen community connections.

Energy Efficiency and Sustainability

The project incorporates strategies for energy efficiency and sustainability. Architects have designed the blocks with thermal performance in mind, ensuring that living conditions are comfortable year-round. Special attention is given to features such as balconies and shading, which allow for better ventilation and reduce energy use.

The design’s offset structure contributes to air circulation, which lessens wind loads on the building. This careful planning reflects a commitment to create worthwhile housing options that respond to the realities of urban living. The focus remains on delivering spaces that are not only functional but also enhance the overall living experience for residents.

`
Competition organisers

The MICROHOME 10 competition invites participants to submit visionary designs for off-grid, modular microhomes that push the limits of sustainable, small-scale living. Organised by Buildner in partnership with Kingspan and Hapi Homes, this tenth edition sets the challenge of designing a dwelling for two people within a maximum floor area of 25 m², encouraging bold solutions adaptable to any urban or rural location. The competition continues Buildner’s mission to foster innovative approaches to compact, energy-efficient housing that can address pressing global challenges.

This year’s edition offers a generous total prize fund of €100,000, including the Kingspan Award for designs that integrate high-performance Kingspan products and the Hapi Homes Award for a project selected for real-world construction. In addition to cash prizes, the winners gain international exposure through Buildner’s media partnerships, publications, and a dedicated MICROHOME magazine, further amplifying their ideas to the wider architectural community.

Key dates for MICROHOME 10 include the closing date for registration on 25 September 2025, the submission deadline on 29 October 2025 (11:59 p.m. London time), and the announcement of winners on 9 December 2025. These milestones ensure participants have clear timelines to develop and present their concepts, with early registration discounts available to support students and emerging designers worldwide.
