IV inHAUS LAB International Competition – ‘Design your modular house’

Rules of the IV Contest for Students and Recent Graduates

The IV inHAUS LAB ‘Design your modular home’ competition reaches its fourth edition. After three highly successful editions and with a very high level among the participants, the leading firm in the premium modular housing sector is once again launching a new challenge to architecture students and recent graduates.

The high quality of the projects received from all over the world and the commitment of the applicants to understand and apply a modular construction system to the design of a single-family home has reinforced the idea of re-launching this competition.

Students and young professionals from multiple disciplines from all over the world have contributed their point of view on single-family housing in recent years, combining it with a way of building that marks the present and future of architecture.

In this edition, new sponsors and patrons have joined the competition. In addition, the jury has a more international character, in line with the firm’s international growth. Their participation is essential for the incorporation of the best candidate projects in the inHAUS catalogue of model homes.

The main objective of the inHAUS LAB ‘Design your modular home’ competition is to promote creativity and innovation in architecture. As part of our mission to disseminate modular design and construction, it seeks to promote new ways of understanding and practising architecture among students and recent graduates of architecture schools and other related disciplines. The competition will reward candidates who excel in their creativity in the search for new modular housing solutions.

Casas inHAUS defends two fundamental principles in professional practice: innovation and creativity. But always linked to the highest construction quality, the optimisation of processes and the improvement of people’s living spaces.

In this new edition, we have managed to bring together a jury of a high level and more than recognised national and international prestige. As usual, they represent the disciplines of architecture and design and are sources of inspiration for the participants.

We also count on the collaboration of our suppliers in the form of sponsorships: Porcelanosa Grupo, K-Line, BC3, Nuovvo, Saloni, Jung, Aislagan and ATSA.

New this year is the Porcelanosa Award for Best Kitchen Design worth €500.


The aim of the competition is to propose a modular concrete house that meets the specifications and provides a technical and formal response to the requirements set out in the competition rules.

The jury’s selection of the best architectural proposals will be included in the inHAUS NEW TALENTS HOUSES COLLECTION (in Spanish only). The models will be produced as many times as customers demand. In return, the winners of the competition will receive royalties for the design.

All the designs submitted have the option of becoming part of the inHAUS Catalogue, such as the Salou, Pedrera and Villalbilla models, winners of the 2019-2020 edition. As previously happened with the modelo Colmenarejo, modelo Bunyola and modelo Benicàssim,  winners of the previous editions.

The competition proposal thus becomes an incentive for young people. It aims to position itself as a support for starting a professional career and, at the same time, to disseminate new construction techniques, encourage creativity, achieve more with less and promote industrialised modular architecture as the best option in terms of both construction quality and design.


Who can apply?

The competition is open to:

  • All students enrolled in the 2022-23 academic year in Architecture or any other discipline related to the sector (Engineering, Design, Interior Design, Decoration…) at any university or college.
