Interior demolition and strip-out on the Costa del Sol, managed for owners who live abroad

What does interior demolition actually include?

Interior demolition is the controlled removal of everything inside a building that the renovation will replace, while the structure, façade and the neighbours' property stay untouched. In practice it covers partition walls, kitchens and bathrooms, wall and floor tiles, screeds, false ceilings, doors, built-in wardrobes and the old installations behind them.

The trade term is strip-out, and a soft strip is its lightest version: fittings, finishes and non-structural elements come out, nothing that carries load is touched. A full strip-out goes further and leaves the apartment or unit as a bare shell, ready for a new layout. Either way, the work is done mostly by hand or with small electric tools, because inside a flat or a shop there is no room for machines and every blow travels through the slab to the people living below.

On this site each type of work has its own page: full interior strip-out, wall removal, including load-bearing walls, kitchen and bathroom strip-out, floors and ceilings, commercial strip-out for shops, restaurants and offices, and hand demolition as a technique in its own right.

Who do we work for?

This site is written for people who own a property on the Costa del Sol but live elsewhere – in the United Kingdom, Ireland, Scandinavia, the Netherlands or Germany. Typically they bought an apartment in the 1970s or 1980s that now needs a new kitchen and an open layout, a villa where three small bedrooms should become two large ones, or a commercial unit that a new tenant wants empty. What they have in common is that they cannot stand on site every morning.

We also work for architects, interior designers and builders who prefer to hand the demolition stage to a specialist and start their own trades on a clean shell. In that case we follow their drawings and their calendar, and the owner simply receives the same photo record.

• Owners abroad renovating a holiday home or a future retirement home.
• Buyers who want the old interior out before their builder prices the new one.
• Landlords and investors preparing an apartment or a shop between tenants.
• Businesses handing back or taking over leased premises.
• Professionals – architects, designers, project managers – who need a reliable demolition subcontractor.

How do we manage a strip-out while you are abroad?

A strip-out can be run remotely if three things are settled before the first day: who holds the keys, who the community administrator is, and how you want to be informed. Once those are clear, you do not need to fly over for the demolition stage.

We start from the photos and measurements you or your agent send, and arrange a visit with whoever has access – a neighbour, a property manager, the concierge or your builder. After the visit you receive a written scope listing what will be removed and what stays, so there is no ambiguity about the built-in wardrobe you want to keep or the radiator that must survive.

During the work you get photos by WhatsApp or e-mail at the moments that matter: the protection of the lift and the stairwell, each wall before and after it comes down, the exposed pipes and cables, and the empty rooms at the end. Hidden surprises – a beam where nobody expected one, old fibre-cement pipes, damp in a slab – are reported with a picture before anyone decides what to do next. You can write to us in English or Spanish; documents from the town hall or the community stay in Spanish, but we explain what they say in plain English.

For owners whose project goes beyond the interior, our sister site explains how a whole demolition is managed from abroad, from paperwork to final clearance.

Can a load-bearing wall be removed in a Spanish apartment?

Yes, a load-bearing wall can often be opened or removed, but only with a design by a técnico competente that defines how the loads are carried once the wall has gone. That person calculates the new beam or frame, specifies the temporary propping and signs the technical documentation; we carry out the demolition part following that sequence and coordinate dates with whoever installs the new structural element.

Many walls in older Costa del Sol blocks are not what they look like. A thin brick wall can carry part of a slab above, while a thick one may be nothing more than an old service shaft. Before any quote for an opening we ask who has assessed the wall. Our guide on how to tell whether a wall is load-bearing lists the signs owners can check, and our blog post on red flags before anyone touches a load-bearing wall describes what should make you stop a contractor.

In a building under propiedad horizontal there is a second step. Under the Ley 49/1960 de Propiedad Horizontal the community has to be informed before walls, structure or façade elements are demolished, and works that affect common elements need the agreement of the owners' meeting. Structure is usually a common element, so the administrator should be involved early.

Do you need permission for interior demolition in Málaga province?

Whether you need a permit depends on what is being removed, where the building is and what the town hall's ordinance says, so the honest answer is: check before you start. In Andalusia the total or partial demolition of buildings is done by declaración responsable since the Decreto-ley 3/2024, unless the building is protected or lies in a protected setting, where a licencia urbanística is still needed. In Málaga city, the 2025 municipal licensing ordinance (OMLU) asks for a project or technical report signed by a técnico competente, a technical certificate and photographs for a works declaración responsable.

Each ayuntamiento – Marbella, Estepona, Mijas, Fuengirola, Benalmádena, Torremolinos and the rest – sets out its own documents and timings, so ask your técnico or the town hall which procedure applies to your works. If a skip, hoist or scaffold has to stand on the street, the occupation of the public road needs its own authorisation. We do not file declarations or obtain licences: that is done by the owner and their técnico. What we do is tell you what the town hall usually asks for, work from the documentation once it exists and adapt our dates to it.

The guide do you need a permit to remove an internal wall in Spain? goes through the situations one by one, and the network's pillar site explains the wider permit regime for demolitions in Andalusia.

Working inside a community of owners

Most interior demolition on the coast happens in apartment buildings, and the neighbours experience the job before you see the result. A well-run strip-out respects three things: the common areas, the working hours and the waste route.

• Common areas. The lift car, landings and stairwell are protected before the first bag of rubble leaves the flat. If the community does not allow the lift to be used for debris, the rubble goes down the stairs in bags.
• Hours and noise. Community rules and municipal ordinances can restrict noisy work to certain hours. We agree a timetable with the administrator and plan the loudest tasks – breaking screed, chasing walls – within it.
• Dust. The apartment door is sealed, windows are used for ventilation rather than the corridor, and the landing is cleaned at the end of each day.
• Information. A short notice in the entrance with the dates and a phone number prevents most complaints.

Our guide to strip-outs in a community of owners explains what to send the administrator, and the one on noise, dust and working hours covers how disruption is kept down.

How the rubble leaves the building

Getting debris out of an upper-floor apartment is often the slowest part of the job, and it is planned before the first wall comes down. Rubble is bagged in the room where it is produced, carried or lowered to street level and loaded out as the work goes, so bags do not pile up on the landing.

In buildings without a lift, or where the lift may not be used, bags go down by hand; on some façades a debris chute or a small hoist is possible if the community and, where needed, the town hall allow it. Where the street is narrow, as in many old town centres, loading is arranged around the times when a vehicle can stop. Our guide on getting rubble out of an apartment without a lift describes each option.

The waste itself is sorted as it is produced. Since 2022 the Ley 7/2022 on waste requires non-hazardous construction and demolition waste to be separated at least into wood, mineral fractions such as bricks, tiles and concrete, metals, glass, plastic and plaster, and selective demolition has been mandatory since 1 January 2024. On an interior job that means separate bags for ceramic rubble, plasterboard and gypsum, metal from old frames and pipes, and wood from doors and kitchen units. The sorted waste goes to an authorised waste manager and you receive the delivery receipts. For larger volumes – a whole building or a commercial unit with concrete floors – our sister site handles rubble removal and skips.

What if asbestos turns up behind the walls?

Asbestos is the one discovery that stops an interior demolition immediately. In buildings of the right age it can appear as fibre-cement (uralita) downpipes and flues inside walls, old water tanks on the roof or in a utility room, or panels in a service shaft. If something suspicious appears, work in that area stops and you receive a photo the same moment.

We do not remove asbestos ourselves. The removal is carried out by a company registered in the RERA that works as our subcontractor, under its own work plan approved by the labour authority, and the asbestos waste is kept apart from all other rubble and delivered to an authorised manager as hazardous waste. We coordinate the rest of the strip-out around it. The current regulation on asbestos work is the Real Decreto 847/2026, in force since late October 2026.

The guide hidden asbestos in interior renovations shows where it usually appears, and our sister site explains how asbestos removal is organised from start to finish.

What does an interior strip-out cost?

We do not publish prices, because two strip-outs of the same floor area can differ completely in effort. What drives the cost is known, though, and you can estimate it yourself before asking for a quote:

• what has to be removed – tiles on a sand-and-cement bed take far longer than tiles on adhesive, and a screed is heavier than the floor covering on top of it;
• whether structure is involved, which adds a técnico, propping and coordination;
• the floor and access – lift or stairs, distance from the door to the loading point, street parking;
• the volume and type of waste and how it must be separated;
• restrictions on working hours in the building;
• surprises such as fibre-cement elements, which need a separate RERA-registered company.

Demolition work generally carries the standard 21 % IVA; some renovation work on private homes may qualify for the reduced 10 % rate if the conditions of the VAT law are met, and each quote states which rate applies. For a rough idea before contacting anyone, the network's interior demolition cost page and its demolition calculator show how these factors add up. The blog post what affects the cost of an interior strip-out in Spain explains each factor in more depth.

Hand demolition or machines indoors?

Inside an apartment almost everything is done by hand: sledgehammers, crowbars, electric demolition hammers and breakers, cutters for clean edges where a wall meets one that stays. Machines would overload the slab and shake the building. Hand demolition is slower, but it is precise, quiet compared with a breaker on a machine, and it lets materials be separated as they come off the wall.

In larger spaces – a ground-floor shop with a thick concrete floor, a basement, a villa where a whole wing is opened – compact equipment can make sense, and we will say so if it does. The comparison is laid out in the blog post hand demolition vs machine demolition indoors and in the guide hand demolition explained. When the job turns into demolishing a whole house rather than its interior, the right place is the network's pillar site for house and villa demolition.

Where we work

We work across the whole provincia de Málaga. Most interior jobs are on the Costa del Sol – Marbella, Estepona, Mijas, Fuengirola, Benalmádena and Torremolinos – and on the eastern coast around Rincón de la Victoria, Vélez-Málaga and Nerja, with inland work in Ronda and Antequera. Our area pages describe what is typical in each: high-rise apartment blocks on the coast, townhouses in old centres with narrow streets, or villas in urbanizaciones where the access road decides how rubble is loaded.

Historic town centres need extra care. Málaga, Ronda, Vélez-Málaga, Antequera, Archidona and Casares have protected historic areas; in a protected conjunto histórico a demolition needs a licence and, where applicable, heritage authorisation, so confirm it with the town hall before planning dates.
