Illustrative example. The case below does not correspond to a specific client: it is a typical La Marina terrace with the problems we most often find, and the materials, timings and prices are the ones we work with on this kind of job. A 40 m² terrace you cannot use: loose tiles, rotten pergola, corroded railings and, worst of all, water filtering into the living room. It is the most common outdoor problem we see in La Marina.
Initial situation
Problem: deteriorated slab with leaks, unsafe railings, damaged pergola
Our proposal
- Full demolition and cleaning
- Professional waterproofing (two layers) and new slopes (1.5%)
- Porcelain anti-slip flooring (60×60, light beige)
- New aluminium railings with tempered glass (1.10 m, low maintenance)
- Bioclimatic motorized pergola with remote control
- LED lighting and exterior electrical points
Budget: €9,200 — Timeline: 12 working days
Execution
Day 1–2: Demolition and removal (2.5 tons debris) Day 3–4: Waterproofing and slope formation (24 h water test) Day 5–7: Tiling with exterior adhesive and expansion joints Day 8–9: Plumbing/electrical points and LED wiring Day 10–11: Railings and pergola installation Day 12: Sealing, cleaning and handover
Result
✅ No more leaks, fully waterproofed ✅ Modern look coherent with the house ✅ Adjustable solar protection with pergola ✅ Low maintenance materials ✅ Safer environment (anti-slip, compliant railings)
Extra benefits
- Lower summer temperature (white louvres reflect heat)
- Usable even on windy winter days
- Increased property value
Cost breakdown
Demolition & disposal: €850 Waterproofing: €1,100 Porcelain flooring + installation: €2,200 Aluminium + glass railings: €2,400 Bioclimatic pergola: €2,100 Electrical installation: €350 Drains & plumbing: €200 TOTAL: €9,200
Lessons learned
- Waterproofing is non-negotiable
- Materials matter (aluminium resists marine corrosion)
- Proper slopes prevent stagnation and damage
- Invest in durability for year-round use
