Related Construction Stages
A House Extension Is Rarely a Stand-Alone Stage
What Comes Before and After Extending Your Home
A house extension in Valencia almost always starts with a separate stage — foundation construction, which has to be correctly tied into the existing footing depending on your soil type and the depth of the original foundation. It usually finishes with facade works and insulation — getting the render, colour and insulation right so the new section doesn't stand out from the old one.
Want more living space but your plot won't allow you to extend outward because of boundaries or the buildable area limit? Consider a second storey addition instead — a separate service with its own permit process that adds space upward rather than outward.

Local Insight
Licencia de Obra for an Extension: Retranqueos and Edificabilidad
Before drawing up an extension, it's worth knowing what your plot actually allows. Every municipality's local zoning plan, the PGOU (Plan General de Ordenación Urbana), sets retranqueos — minimum setbacks from neighbouring boundaries, the street and other buildings that a new structure cannot cross — and edificabilidad, a build ratio that caps the total floor area allowed on the plot. If your house is already close to that limit or sits near a boundary, a straightforward extension may not be possible in the form you imagined, and a different solution — such as a second storey addition — may fit better. We request the relevant zoning report before design work starts, so the real limits of the project are clear from day one, then handle the licencia de obra application with the ayuntamiento (town hall), protecting your investment and ruling out the risk of having to demolish unauthorised work later.

★★★★★
We added a second bedroom and a home office at the back of the house. The new foundation was tied in so cleanly you can't tell where the old wall ends and the new one begins.
★★★★★
We were worried about what we could actually build — our plot is small. squaremeter Reformas checked the setback rules and buildable area first, explained what was realistic, and handled the permit themselves.
★★★★★
We stayed in the house the entire time. They planned the work so the mess stayed outside, and the roof tiles and render now match the original house perfectly.
House Extension
FAQ
How do you confirm what can legally be built on my plot?
Before designing an extension, we review your municipality's zoning plan (PGOU) to check the setback rules from neighbouring boundaries (retranqueos) and the remaining buildable area on your plot (edificabilidad) — this determines how many square metres you can actually add, and how close to the boundary.
+
How long does a house extension in Valencia take?
Timelines depend on the size of the extension, how complex the tie-in to the existing structure is, and how long the licencia de obra takes to approve at the town hall. A single-room extension is usually quicker than one that adds a new kitchen or living area with more complex utility connections.
+
Will the extension match the style of my existing house?
Yes. We match the roof material and pitch, the facade colour and texture, the cornice height and window profiles so the extension reads as part of the original house rather than a separate addition.
+
Can I keep living in the house while the extension is being built?
In most cases, yes, since the main works happen outside the existing walls. We agree temporary connection points for utilities and organise the site to minimise disruption to your family, particularly during the stage when we open the connection between the house and the new section.
+
What determines the price of a house extension?
The quote is based on the size of the extension, the foundation type for your soil, the complexity of tying the roof into the existing one, the engineering systems needed and the level of interior finishing — we give you an exact figure after inspecting the house and plot.
