In short
Terrace and outbuilding demolition removes slabs, porches, pergolas, sheds, pool houses and garages from a villa plot, separating concrete, ceramics, timber and metal for an authorised facility. It is often combined with a pool removal so the garden can be redesigned in one go.

What counts as a terrace or outbuilding demolition?
Terrace and outbuilding demolition covers the secondary structures of a villa plot – everything that is not the house itself but is built and fixed to the ground. In practice we remove:
- terraces and pool beaches: concrete slabs, tiled or stone-paved platforms, raised decks on block walls;
- porches and covered terraces attached to the house, with their pillars and roof;
- pergolas in timber, steel or aluminium, including their footings;
- pool houses, pump rooms, changing huts and barbecue areas;
- sheds, workshops, storerooms and single garages.
If the structure is part of the house – an annex sharing walls with the main building, or a storey on top of it – the job is a partial demolition of the house, which our main site covers under partial demolition.
Terrace demolition: slabs, tiles and what lies beneath
A terrace demolition is usually more concrete than people imagine. Under the tiles there is mortar, a slab – often reinforced – and sometimes a raised platform built on block walls and filled with rubble. We break out the surface, separate the ceramic tiles from the concrete, cut out the mesh and remove the footings, so that what is left is soil and not a crust of old concrete under the new lawn.
Where the terrace runs up to the house, the cut line is planned so the façade, the damp-proofing and the drainage of the house are not damaged. If the terrace surrounds a pool, it is normally removed with the pool: see pool demolition. The guide demolishing a terrace or porch in an urbanización deals with estate rules and neighbours.
Porch demolition and pergola removal
Porch demolition and pergola removal are about doing things in the right order. A porch roof is taken down first – tiles, battens, beams – then the pillars and finally the footings. A pergola is lighter but often has steel posts concreted into the ground; we pull or break out the bases rather than cutting them flush, because stumps of steel left in the ground cause problems when the area is replanted or paved.
Timber from old pergolas is kept apart as wood, steel and aluminium as metal. Reed or plastic shading, cushions and furniture are yours to clear before we start, or we agree in the quote that we take them as a separate item.
Shed, pool house and garage demolition
Shed demolition and garage demolition are small jobs in size but full demolitions in method: roof, walls, slab and footings, with each material separated. Before the work, the electricity, water and any gas to the building are disconnected by the relevant installer; we do not cut live services.
Roofs need a careful look. Corrugated grey sheets on older sheds, garages and pool houses may be asbestos cement. If that is possible, the roof is not demolished with the rest: the removal is carried out by a RERA-registered company working as our subcontractor, under its own approved work plan, and we coordinate the rest of the demolition. Asbestos waste is kept separate and never mixed with other rubble. Our sister site explains asbestos removal in detail.
Outbuildings in an urbanización: community and neighbours
Many villas on the Costa del Sol sit in urbanizaciones with a community of owners and shared walls, roads and gates. If the outbuilding or terrace touches common elements – a boundary wall shared with a neighbour, the estate road used for access – the community must be informed, and works on common elements need the agreement of the owners' meeting. We coordinate dates, machine access and working hours with the administrator so that the estate knows what to expect.
Lorries parked on a public street need an authorisation to occupy the public road from the town hall. Inside a private estate, the community's own rules about access and hours apply.
Permits for demolishing a terrace or outbuilding
A terrace, porch, shed or garage is a construction, and its demolition in Andalusia is generally processed by declaración responsable since Decreto-ley 3/2024, provided the property is not protected or in a protected setting. The owner files it with the ayuntamiento, normally through their técnico, and each ayuntamiento sets the documents in its ordinance. We work with that documentation and coordinate dates with your técnico.
If the structure was built without a licence, the situation is a matter for your técnico or lawyer before any work starts; we do not advise on legalisation. The guide do you need a permit to remove a pool in Spain? explains the declaración responsable route, which applies in the same way to outbuildings.
Combining outbuilding demolition with the rest of the garden
Removing an old pool house without touching the pool, or a terrace without the wall below it, often means coming back a second time. When the garden is being redesigned, list everything that should go and we plan one sequence: structures first, then the pool, then plot clearance and basic levelling. For an honest picture of what changes the cost, read what changes the cost of removing a pool, which applies just as much to terraces and sheds.
What decides the time and cost of an outbuilding demolition?
Size matters less than people expect. A small block pool house with a reinforced slab and deep footings can take longer than a large timber pergola, because concrete is what costs time to break and tonnes to transport. The main factors are:
- the construction – timber, steel, block, brick or reinforced concrete;
- slabs and footings below ground, which are often thicker than the structure suggests;
- the roof, especially if fibre-cement sheets need a specialist subcontractor;
- access for a compact machine, or the need to work and carry out by hand;
- the number of material fractions to sort and the volume of rubble.
For a rounded band before you ask for a quote, the demolition calculator on our pricing site covers outbuildings and terraces as well as pools.
Frequently asked questions
Can you remove a terrace without damaging the house?
Yes. The cut line along the façade is planned before breaking, and the last strip next to the wall is removed with lighter tools to protect the house and its damp-proofing.
Do you remove the footings of a pergola?
Yes. Concrete bases and steel posts are broken or pulled out rather than cut flush, so nothing is left to obstruct planting or paving.
Can you demolish a garage attached to the house?
A garage sharing walls with the house is a partial demolition of the building and needs a técnico's input on the shared wall. A free-standing garage is a routine outbuilding demolition.
What if my shed roof might be asbestos?
It is removed separately by a RERA-registered company working as our subcontractor, under its own approved work plan. We demolish the rest of the shed afterwards.
Who disconnects electricity and water to the pool house?
Your electrician and plumber, or the relevant installer, disconnect the services before we start. We never cut live supplies.
Do I need a permit to demolish a porch?
A porch is a construction, so its demolition is generally processed by declaración responsable in Andalusia unless the property is protected. Your técnico confirms the procedure with the ayuntamiento.
Can the rubble from the terrace go into the pool infill?
Clean broken concrete can form the bottom layer of a pool infill if your técnico agrees. Tiles, timber, metal and plastic are always taken away separately.
Do you remove garden furniture and plants?
Furniture and loose items are cleared by the owner before the work, or included as a separate item in the quote. Plants in the way of the demolition are removed as part of the job.
What is left once the outbuilding is gone?
Clean ground at a basic level, without footings or slabs, ready for your landscaper or builder.
Can you work in a gated estate?
Yes. We coordinate dates, hours and access for machinery with the community administrator.
