Home Extensions in Mallorca
An extension adds floor area rather than reworking the floor area you have, and what may be added is a question about the plot before it is a question about the house. Describe the property and what you want, and we pass the request to renovation and building companies on Mallorca that build them.
The first question is what may be built, not what you want
Every plot carries a limit on how much of it may be built on and how high, and on Mallorca a property is often already close to it. The limit belongs to the plot rather than to the house, so two neighbouring properties can have very different answers and neither is obvious from the street.
That is why an extension normally starts with a technical team rather than with a builder. Somebody establishes what the plot allows and draws what is possible, and only then is there something a building company can price rather than estimate. Skipping the step produces quotes for a building that may never be built.
The second question is what the existing house can carry. An extension that ties into the old structure, opens a wall into it or sits on top of it is structural work as well as building work, and the two are priced together or not properly at all.
Kinds of extension people ask about
- A ground floor extension into the garden or along the side
- Enclosing or roofing over an existing terrace
- Adding a storey, where the structure below allows it
- A basement or a lower level cut into a slope
- A separate annexe or guest building
- Converting a garage or a store into living space
- A pool house, an outdoor kitchen or a covered terrace
- Connecting the new space to the services the house already has
How an extension usually runs
Almost all of the risk sits in the first two steps, and almost none of the cost.
-
01
What the plot allows
A technical team establishes what may be built before anything is designed. This is the step that decides whether the project exists at all.
-
02
Design and drawings
What is possible gets drawn, roughly costed and agreed. Changes here are cheap; changes after here are not.
-
03
Permissions
What the work needs depends on what it touches and where the property is. The company quoting it says what it needs before it can price the build.
-
04
Groundwork and structure
Foundations, the tie into the existing building, and whatever the existing structure needs in order to carry the new one.
-
05
Envelope
Walls, roof, windows and doors, until the new space is weathertight and the old house is closed up again.
-
06
Services and finishes
Electrical, plumbing, heating and cooling extended into the new area, then the finishes.
-
07
Making good
The join between old and new, inside and out. It is the last thing done and the first thing anybody looks at.

How your request reaches a company
Mallorca Renovation is a comparison service. A request for an extension goes to the renovation and building companies on our list; they quote the work and carry it out, and any agreement is between you and the company you pick.
-
01
Describe the job
Tell us the property, roughly what you want and where it is. Photographs and a rough plan help, though neither is required.
-
02
We match it
The request goes to companies that work in your area and take on this kind of job at this size.
-
03
They quote you
Each company contacts you directly with its own price, timing and approach. We do not set any of it.
-
04
You compare and choose
Put the quotes side by side and take the one you want, or none of them. Using the site costs you nothing.
Do I need drawings before I can get a price?
For anything beyond the simplest addition, yes. A building company can price a drawing. It cannot price an idea, and a figure given without one is a guess that will move.
Can any house be extended?
No, and the question is about the plot rather than about the house. It is worth establishing at the very beginning, because it costs very little to ask and a great deal to assume.
Is it cheaper to extend or to reorganise what is there?
Reorganising is often cheaper, because an extension carries foundations, a roof and an envelope that a layout change does not. Whether it gets you the same result is a separate question, and both are worth pricing.
Can we live in the house during an extension?
More often than during a full renovation, because much of the work happens outside the existing walls. The exception is the period when the two are joined together, which is noisy, dusty and thankfully short.
