Total usable floor area: 351.02 m²
Total built floor area: 381.92 m²
3. Design & Siting Principles
- The home sits on the gentlest slope of the plot (under 10%), minimizing earthworks.
- Orientated west, angled slightly east, to reduce heating and cooling costs.
- Raw-white façade finish, in keeping with traditional Ibizan rural architecture.
- Existing stone walls, over 60 years old, will be restored.
- Landscaping with native vegetation, preserving the existing carob and almond trees.
4. Construction System
Structure — Isolated and strip footings tied with ground beams, on favorable ground conditions. Reinforced concrete frame with load-bearing concrete block walls and one-way slabs.
Envelope — Flat, non-trafficable roof finished in fine tile. Cavity-wall façade: concrete block (20 cm) + air gap (2 cm) + extruded polystyrene insulation (4 cm) + interior partition wall (4 cm) — 30 cm total thickness. White lacquered aluminum exterior joinery with thermal break and double glazing.
Finishes — Anti-slip porcelain stoneware flooring in wet areas, anti-mold plastic paint on interior walls, ceramic tiling in bathrooms. Oak interior joinery.

- Fire safety (DB-SI)
- Safety in use (DB-SUA)
- Health & sanitation (DB-HS)
