For Houses That Need More Than an Extension
Older Houses, Inherited
Properties and Homes
Outgrown by Your Family
This service is built for houses where a simple extension isn't enough — a village house (casa de pueblo) with visible cracks and settlement, an inherited property that needs modernising and enlarging at the same time, or a family home that has outgrown its footprint while also showing its age. We treat the structure and the space problem as one project.
- ✓ Older houses with cracks, damp or settlement
- ✓ Inherited properties needing modernisation and more space
- ✓ Village houses (casas de pueblo) with tired structures

How This Differs From a Standard Extension
When to Choose Reconstruction Instead of a Straightforward Extension
If your existing structure is sound and you simply want more space, a house extension or a second storey addition on its own may be all you need — both are simpler, faster projects. Reconstruction and expansion is the right choice when the structure itself needs attention first, which is why it usually starts with dedicated foundation construction work to correct or reinforce what's already there.
Because this type of project falls under licencia de obra mayor, we also coordinate closely with building permit services from day one, rather than treating the paperwork as an afterthought.

Local Insight
Licencia de Obra Mayor: Why Structural Projects Need an Architect
Any project that touches a building's structure, footprint or use in Spain falls under licencia de obra mayor rather than the simpler licencia de obra menor used for cosmetic work. That means a formal proyecto básico y de ejecución has to be prepared and signed off by a qualified architect, submitted to the ayuntamiento (town hall) along with a structural report where relevant, and, once the work is finished, closed out with a certificado final de obra. That final certificate is also what lets you update the property's registered floor area at the Catastro (the Spanish land registry) — skipping this step is a common reason owners run into problems later when selling or getting a mortgage on a property with undeclared square metres. Because the stakes are higher on a reconstruction than on cosmetic renovation, we bring the architect and structural engineer in early, before any demolition starts, so the reinforcement plan and the expansion design are approved together rather than in separate, conflicting stages.

★★★★★
We inherited my grandmother's house with visible cracks in two walls. squaremeter Reformas's structural survey found the real cause, reinforced the foundation, and we ended up with a second storey we hadn't originally planned for.
★★★★★
We were quoted for a simple extension elsewhere before anyone actually checked the beams. Glad we didn't go ahead — the structural survey here changed the whole plan for the better.
★★★★★
The licencia de obra mayor process sounded intimidating from abroad. They handled the architect, the town hall and the final registration, and kept us updated in English the entire time.
House Reconstruction & Expansion
FAQ
What's the difference between a house extension and house reconstruction & expansion?
A house extension adds new floor area to a house whose existing structure is already sound. House reconstruction and expansion is for houses that need structural work — reinforced beams, new foundations, ring beams — carried out at the same time as adding floor area, so the whole building is brought up to standard in one project instead of two.
+
Do I need an architect for this kind of project?
Yes. Projects that change the structure, the footprint or the use of a building require a licencia de obra mayor, which needs an architect-designed and stamped project (proyecto básico y de ejecución) submitted to the town hall. We coordinate this as part of the service.
+
How do you know if my house needs structural reinforcement?
We start with a structural survey, checking for cracks, sagging beams, damp, settlement and the condition of the foundations. For older houses we often recommend a formal informe estructural (structural report) before finalising the design, so the reinforcement plan is based on facts, not guesswork.
+
Will the additional square metres be officially registered?
Yes. Once the project is finished, we help you obtain the certificado final de obra and pass the documentation needed to update your property's registered floor area with the Catastro (the Spanish land registry), so the extra space is reflected in your official records.
+
How long does a house reconstruction and expansion project take?
It depends on how much structural work is needed, the size of the added floor area and how long the licencia de obra mayor takes to approve at the town hall. A project combining structural reinforcement with a second storey typically takes longer than a straightforward extension of a sound structure.
