Vertical Expansion with Fiber Cement and Wooden Additions for Urban Housing

Project in-detail

Combining vertical residential units with lightweight wooden construction and fiber cement siding, the design reimagines existing plattenbau structures to enhance urban housing density and sustainability.
5 key facts about this project
01
Incorporates scaffolding to ensure sunlight access for all residential units.
02
Utilizes removable installation segments for efficient utility management.
03
Features lightweight wooden construction for quick assembly and transport.
04
Prioritizes rainwater management with integrated reservoirs and septic systems.
05
Enhances existing plattenbau structures by adding vertical residential units.

The Parasite House project addresses housing challenges linked to plattenbau structures in urban areas like Warsaw. Developed during the housing crisis of the 1950s, these buildings used prefabricated concrete slabs to offer affordable solutions. However, as urban needs evolve, the limitations of plattenbau construction regarding density and livability are becoming clearer. The Parasite House concept looks to improve these structures by adding new living spaces that extend vertically along their facades, enhancing the function without requiring more land.

Architectural Concept

The design introduces a model that expands vertically, allowing the creation of new residential units that rise along existing walls. By doing this, it increases housing density while preserving the character of the original buildings. The project aims to blend old and new elements, fostering a sense of continuity in the urban landscape.



Light and Sustainability

Ensuring natural light reaches all living units is a crucial aspect of the design. Scaffolding is used not just for support during construction but also to maintain access to sunlight for residents. The careful positioning of photovoltaic systems takes advantage of the buildings' east-west orientation, ensuring effective solar energy capture and promoting greater sustainability in energy usage.



Water Management

Water and energy management are also key considerations in the design. The Parasite House includes a removable installation segment that provides clean water and electricity to residents. Effective solutions such as rainwater reservoirs and a septic system help manage essential utilities, reducing the overall environmental impact in a city setting.



Materiality

Lightweight wooden construction is chosen for its benefits in transport and installation. This approach fits with current sustainability practices and allows for speed in assembly while maintaining structural strength. Additionally, fiber cement siding adds durability and improves the appearance of the new living spaces, helping them blend with their surroundings.

The outcome results in flexible living areas that meet modern demands. Features such as two independent workspaces cater to the rising trend of remote work, reflecting the need for multifunctional environments in today’s urban life.

MICROHOME 10: Celebrating Small-Scale Living with €100,000 Prize Fund and Kingspan’s Innovation

`
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.
