Building homes across Europe since 2017.
Promiris is a residential developer operating in Belgium, Portugal, and Spain. Founded in 2017, we have delivered 29 projects across three countries — each one built around the people who will live there.
How we work
Across three markets
Belgium, Portugal, and Spain — three countries with different climates, regulations, and buyers. Our local teams know each market from the inside. We don't parachute in; we build relationships, understand the neighbourhood, and commit to the long term.
Across residential formats
Residential apartments for families. Purpose-built student residences. Mixed-use urban regeneration. We work across all residential formats because the discipline of delivering on time and on spec applies equally to all of them.
Built for every generation
Young people starting out, families settling in, seniors wanting independence with security. Our portfolio spans all life stages — which means we understand what makes a space genuinely liveable.
Founded on discipline. Built on proof.
Promiris was established in 2017 by three partners with deep roots in European real estate. Since then, we have grown from a Belgian developer into a tri-market operation — with local teams in Brussels, Porto, Lisbon, and Barcelona — while keeping the decision-making structure flat and the commitment to quality non-negotiable.
We work with architects, engineers, and contractors we have built genuine partnerships with. Sustainability targets are shaped with recognised frameworks such as BREEAM in mind, and any formal certification is stated project by project where achieved.

Common questions
-

Promiris was founded in 2017 in Belgium. Since then, we have expanded to Portugal and Spain, building a portfolio of 29 projects totalling 187,000 sqm and €600M in investment across the three markets.
-

-
Does Promiris develop outside Belgium, Portugal, and Spain?
Currently, all active projects are in these three markets. Our focus on disciplined execution means we grow deliberately — expanding to new markets only when we have the local team and relationships to deliver to our standard.
-
What makes Promiris different from other European residential developers?
Promiris combines local market knowledge, disciplined delivery and a long-term view of residential quality. We develop with sustainability standards in mind, using recognised frameworks such as BREEAM as references where relevant.
