MICROHOME 2026
Competition Brief
The €100,000 Prize / Kingspan MICROHOME 2026 is an open international architecture ideas competition organised by Buildner in partnership with Kingspan. Participants are asked to propose an off-grid modular dwelling of no more than 25 m² for a hypothetical young professional couple, on any imagined site worldwide. Submissions are anonymous and must be prepared in English. The current competition page lists registration closing on 30 September 2026, project submission on 2 November 2026 at 11:59 p.m. London time, and results on 15 December 2026.
The brief frames the small dwelling not as a minimal object but as a concentrated test of spatial efficiency, environmental performance, and architectural judgment. Entrants are expected to examine how a highly compact home can remain livable, adaptable, and emotionally convincing while incorporating off-grid strategies for energy, water, and waste. There is no fixed real-world site and no stated construction budget cap, though the brief recommends financially rational solutions. Kingspan-specific recognition is available for teams that integrate the company’s products or systems into their proposals and explain their contribution to performance, sustainability, and appearance.
What is the competition about?
This programme continues Buildner’s long-running MICROHOME series and focuses on the question of how much space a dwelling truly needs. The organisers position the challenge within wider pressures affecting housing today: affordability, climate response, material efficiency, and the search for more adaptable domestic models. Rather than asking for a standard house reduced in size, the brief calls for a rethinking of how sleeping, living, working, cooking, hygiene, and storage can coexist within a very small footprint.
The competition is not tied to a single planning context, region, or climatic zone. That gives entrants latitude in choosing the environmental and cultural conditions their proposal addresses, but it also places greater responsibility on each team to justify site assumptions, technical logic, and the relationship between concept and context. The stated benchmark user is a hypothetical young professional couple.
What is required?
Entrants must design an off-grid modular home with a total floor area not exceeding 25 m². The proposal should accommodate a sleeping area, living/working area, cooking space, WC and shower, and small storage. The programme is described as flexible, which means these elements may be reorganised or interpreted in different ways if the overall concept remains coherent and habitable.
The brief encourages cost-conscious construction thinking, environmental responsibility, and energy efficiency. It also asks for conceptual solutions for electricity generation, water collection and filtration, and waste management. Participants may choose any hypothetical site worldwide, urban or rural. Outdoor elements such as terraces, paths, and similar non-essential components are not counted as buildings in the brief’s description of the area limit. For the Kingspan Award track, proposals must incorporate Kingspan products or solutions and explain their contribution clearly.
What must be submitted?
The submission package described in the official brief consists of four digital presentation panels, a short written statement, and a material specification list. All material must be anonymous and in English. The competition page also states that entries are uploaded through the Buildner user portal after registration and UIC validation.

✦ ArchUp Competition Review
Kingspan MICROHOME 2026 is a disciplined brief with broad international relevance. Its strength lies in the clear central task: compressing domestic life into 25 m² without treating compactness as novelty alone. Because the site is hypothetical, the competition rewards entrants who can build a convincing relationship between context, construction logic, and environmental systems rather than relying on image-making. The open eligibility and anonymous judging structure are practical advantages, especially for students and small studios. The main caution for participants is that the freedom of the brief also raises the burden of proof: weak projects will struggle if they do not explain why their chosen setting, modular strategy, and off-grid systems form a coherent whole. For teams interested in housing prototypes, prefabrication, and low-impact living, this is a substantial ideas competition with meaningful visibility and a serious prize structure.
