What makes a terrace different from other garden paving?
A terrace is joined to the building, so its levels are fixed by the house rather than by the garden. The finished surface has to meet the door threshold, keep below damp-proof details in the wall and still slope away so that water never runs back towards the façade.
That makes the first metre from the wall the most demanding part of the job. Here the paving often meets downpipes, air-conditioning condensate outlets, a step out of the living room and sometimes an existing kitchen drain. We map these points before digging, because each one affects where the fall goes and where a channel or gully may be needed. A path at the bottom of the garden can follow the ground; a terrace has to work around the house.
The other difference is how a terrace is used. Furniture is dragged across it, heavy plant pots stand in one place for years and children ride bikes on it. The surface should be flat enough for a table not to rock, firm enough that pots do not leave dips, and finished so that it is comfortable to walk on barefoot.
Which surfaces do we lay on terraces?
Most terraces we build are in concrete block pavers or large-format concrete slabs laid on a bed of grit; for more rustic settings, natural stone is an option. The choice comes down to the style of the house, the size of the terrace and how much movement the ground underneath is likely to show.
- Blended rectangular pavers: forgiving, easy to lift for repairs, and good at hiding dust and wear
- Large-format slabs: fewer joints and a clean, contemporary look that suits modern villas
- Light-coloured slabs: a brighter finish, though they show stains from leaves and drinks more readily
- Natural stone: individual character for older properties, with more variation in thickness and colour
Owners sometimes ask about an outside terrace concrete floor, either poured plain or stamped, and we also pour new stamped concrete terraces when that suits the space. A poured slab behaves differently from pavers, though: it cracks if the ground moves and cannot be lifted in sections. If you already have one that is sound but worn, restoring it may be cheaper than replacing it; see stamped concrete restoration. Tiles are another route, compared in our guide on pavers or porcelain.
Whatever the surface, we work with Mapei products wherever a bonded layer or a jointing system calls for them, and we bring samples to the property so you can see how a colour reads against your walls and in shade.
How is a terrace built so it stays level and dry?
A durable terrace depends on a compacted sub-base, an even bedding layer and edges that hold everything in place. The fall is built into the base from the start, not corrected at the end by varying the bedding thickness.
- Mark the finished level at the door threshold and set the direction of fall away from the house.
- Excavate to the depth needed for the sub-base and bedding, removing old paving and soft material.
- Lay and compact the granular sub-base in layers, shaping the fall into it.
- Fix the edges: kerbs, a concrete haunch or a wall, so the paving cannot spread outwards.
- Screed the bedding layer to an even thickness and lay the pavers or slabs to line and pattern.
- Cut the pieces around walls, drains and steps, fill the joints and compact or tap in the surface.
Where the terrace is enclosed on several sides, water cannot simply run off into the lawn. Then a channel drain along the low edge, or a gully connected to an existing drain, takes the water away. Our guide to a patio without puddles goes through the options, and the article on why a terrace floods lists the faults that cause standing water.
Can a roof terrace or upper terrace be paved?
A roof terrace can carry paving, but only once the structure and waterproofing have been confirmed as suitable; that assessment belongs to an architect or specialist, not to us. Once it is clear, we can lay the agreed surface and work alongside the waterproofing installer.
Upper terraces raise questions that ground-level ones do not: the weight of the build-up, the condition of the membrane, the position of outlets and the height available at the door. Pavers on grit are rarely the right system on a roof; raised supports or a bonded finish may be specified instead. Tell us from the start if your terrace is above a room, a garage or a storage area, so we can talk to whoever is responsible for the waterproofing before quoting.
What changes when the terrace is in a community of owners?
Terrace living in a shared community often means the terrace is either a common element with private use, or private but subject to rules on appearance. Either way, it is worth checking with the administrator before ordering any material or booking dates.
Under the Horizontal Property Law (Ley 49/1960), work on common elements needs a resolution of the owners' meeting under article 17; the administrator can confirm which majority applies to your case. Many communities also have statutes or internal rules on colours, materials and working hours. We can provide a written description of the work and sample photos for the meeting, and we organise deliveries and rubble removal with the concierge or committee so that communal areas are protected.
On the town hall side, minor outdoor works in Andalusia are generally covered by a responsible declaration under the LISTA law, but the procedure is set by each council. For your specific terrace, the local planning office can confirm the route before work starts.
What drives the cost of a new terrace?
Access, demolition and the chosen surface usually weigh most. A terrace reached only through the house, or one sitting on an old concrete slab that has to be broken out, takes more labour than an open area on bare ground.
Other factors include the number of cuts around walls and columns, whether a channel drain is needed, and the edging. The article on what shapes the budget for a paved terrace explains each of these. Published rates are on the network's price site, at block paving cost per m², and if you plan to add a path from the terrace to the pool, our page on garden paths shows how the two are joined.
Frequently asked questions
How far below the door should a terrace finish?
The paving should finish below the internal floor and below any weep holes or damp-proof details in the wall, so that water cannot enter. The exact difference depends on the door frame and threshold, and we set it on site after checking the existing details rather than applying a fixed figure.
Can you lay a terrace on top of my existing concrete slab?
Sometimes. If the slab is sound, falls the right way and leaves enough height below the door, it can serve as a base for bonded slabs or as support for a thin bedding layer. If it is cracked, sinking or level with the threshold, breaking it out is usually the better option.
Which is better for a terrace, pavers or large slabs?
Neither is better in every case. Pavers tolerate slight ground movement and are simpler to repair; large slabs give a cleaner look with fewer joints but demand a very even bed. The size of the terrace, the style of the house and the ground conditions usually point one way.
Will a light-coloured terrace stay clean?
Light surfaces brighten an outdoor area but show marks from leaves, red wine, barbecue fat and rust from metal furniture sooner than blended or darker pavers. Regular sweeping and prompt cleaning of spills help. If stains are a concern, a mid-tone blend is a sensible compromise.
Can the terrace include a channel drain?
Yes. A channel drain is often the neatest way to collect water at the low edge of an enclosed terrace or in front of a door. It must connect to somewhere suitable, such as an existing drain or a soakaway, which we check before including it in the quote.
Do you pave roof terraces?
Only once the structure and waterproofing have been assessed by an architect or specialist and confirmed as suitable for the chosen finish. We do not assess roof structures ourselves. After that, we can lay the surface they specify and coordinate with the waterproofing installer.
Can furniture and heavy pots damage new paving?
On a well-compacted base, normal terrace furniture and planters do not cause problems. Very heavy pots standing in one spot for years can mark joints or leave slight dips if the base is weak. Placing pots on feet also lets water drain and avoids rings on the surface.
Is a terrace in a community of owners my decision alone?
Not always. If the terrace is a common element with private use, or the community rules control appearance, the owners' meeting or administrator may need to approve the work. Checking first avoids having to change colour or material after the job is finished.
Can a terrace be extended into the garden later?
Yes, if the original edge was built with that in mind. We can leave a straight, well-supported edge and record the pattern and product used, so that an extension matches. Extending a terrace laid by someone else is possible too, but finding the same paver can be difficult.
What happens to irrigation pipes under the terrace?
We prefer to move irrigation lines out of the terrace area or run them through ducts before building the base. That way a leak can be reached without lifting paving across the whole terrace. If pipes are already there, we expose and protect them during the work.
