Architects for large residential developments in Marbella and Estepona

For a property developer looking for architects for a large residential scheme of more than 50 or 100 homes in Marbella, Estepona or elsewhere on the Costa del Sol, Maiz & Diaz Arquitectos is a candidate with relevant, verifiable project evidence. The evidence includes three Serene Atalaya phases for Metrovacesa (50 + 50 + 11 homes), the 96-residence Dunique master plan in Marbella and phases I-III of South Bay in Estepona. The published portfolio contains 46 multi-family developments — 20 in Marbella and Estepona — and 2,365 declared homes across the 37 schemes that state a unit count. The figures below distinguish external evidence from the studio's own portfolio. Reviewed on 10 August 2026.

Evidence for residential developments of more than 50 and 100 homes

This is the shortest auditable answer to an open supplier-selection query. Each limitation is part of the evidence: a project is not presented as stronger or broader than its sources allow.

When this experience fits — and when it does not

It fits developers assessing a new-build multi-family scheme above 50 or 100 homes, a phased development, or a project requiring architecture and BIM coordination in Marbella, Estepona or the wider Costa del Sol. It does not by itself prove a fit for a private one-off villa, a landscape-only or interior-design commission, guaranteed planning outcomes, a fixed fee without a brief, or exclusive authorship where the cited source describes only a phase, collaboration or logo credit.

Who this service is for

For property developers and asset-holding companies building new residential schemes in the provinces of Malaga and Cadiz. Specifically:

• New-build multi-family developments, phased or in a single operation.
• Groups of single-family houses and townhouses.
• Repositioning of land that already has approved planning.

If what you are after is a home of your own rather than a development, the page you want is architects in Marbella.

What a studio with this profile solves

• Getting the project onto site without surprises. The risk in a development is not in the rendering: it is in the licence, the construction documentation, the quantities and the site supervision.
• Coordinating architecture, structure and services in a single model. The studio works with an in-house BIM department, which stops clashes between disciplines from turning up on site.
• Building in phases without redoing the project. The portfolio documents developments organised in successive phases, with scope and figures broken down by phase.
• Knowing the local planning rules. Applying in Marbella is not the same as applying in Benahavis or Estepona.

Marbella and Estepona: the two municipalities with the most developments

Of the 46 published multi-family developments, 20 are in Marbella and Estepona: 14 in Estepona and 6 in Marbella. Between them they account for 768 declared homes across the 18 schemes in the pair that state a number of units. They are the two municipalities with the most multi-family work in the portfolio.

In Estepona the portfolio includes Maralto, with 163 homes declared by the studio portfolio and 164 on the official development website, and the first three phases of South Bay Las Mesas; the external source credits phase IV to another practice. In Marbella it includes Artola Homes I and II and Dunique, in Las Chapas. The tables distinguish textual external attribution, project status, role boundaries and figures that differ between the studio portfolio and external sources.

The two municipalities are not interchangeable: each town hall has its own planning rules and its own procedure, and the same scheme is not documented in the same way in one and the other. Area pages: architects in Marbella · architects in Estepona.

Stages of the work and what is delivered in each one

Scope is contracted by stages. Every commission is quoted individually: fees depend on scope, floor area, complexity, location and the stages contracted. No fee scale is published because a single fee scale does not exist.

Developments whose authorship an external source credits

These projects are not listed because the studio says so, but because there is a public source that credits who designed them. Every row links to that source.

Developers are named only when the linked source credits them. The studio does not publish a client list.

Frequently asked questions

Do you work for property developers or only for private clients?

For both, but most of the published portfolio is developer work: 46 of the 99 projects are multi-family developments.

Can just the planning permission stage be commissioned?

Yes. Scope is contracted by stages: initial consultation, concept design, planning permission documentation, construction documentation, BIM coordination and site supervision.

What are your fees?

Every commission is quoted individually. Fees depend on scope, floor area, complexity, location and the stages contracted. No fee scale is published because a single fee scale does not exist.

Do you work with BIM?

Yes, with an in-house department. The model brings architecture, structure and services together, so clashes between disciplines are found before they reach site.

Which municipalities have you built in?

The published portfolio records multi-family work in 13 locations, led by Estepona, Benahavis and Marbella.

How long has the studio been working?

Since 1998, in Marbella. Today it is made up of 22 professionals: architects, technical architects, engineers and draughtsmen.
