About this service
The MEP load steps up. So does the design effort.
4-bed apartments in Barcelona are typically pre-war Sarrià, Pedralbes, Sant Gervasi or upper Eixample — generous in surface (125-180 m²), often with original mosaic tile and 3.5 m ceilings, but always with electrical and plumbing that's 60+ years old. The reform is a near-rebuild, contracted at three-phase if a heat pump goes in.
02
Master suite as one design unit
Bedroom + en-suite + dressing room are designed as one unit, not three rooms. Three classic layouts: linear (row), en-suite priority (corner dressing), walk-through (dressing between bedroom and en-suite). Núria draws all three on the first visit and the family picks the one that fits how they live.
03
Three-phase contracted power
4-bed flats with 5+ AC zones, induction hob, EV charger or aerotermia heat pump usually need three-phase 9.2-14.5 kW from Endesa. Joan files the contract upgrade as part of the project. Without three-phase the panel selectivity is harder and the heat pump can't run continuously.

Common 4-bed questions
Things owners ask before signing.
3-bed = three private zones with a master en-suite plus a shared family bathroom. 4-bed = master suite (bedroom + en-suite + dressing room or walk-in wardrobe) + 3 secondary bedrooms + 3 bathrooms total + a separate laundry zone. The MEP load steps up another level — typically 9.2 kW contracted, possibly three-phase if you specify a heat pump or an EV charger.
125-180 m² in Sarrià, Pedralbes, Sant Gervasi or upper Eixample. Master suite 22-30 m² (bedroom 14-16 m² + en-suite 5-7 m² + dressing room 4-6 m²), 3 secondary bedrooms 9-13 m² each, 3 bathrooms total (master en-suite + family bathroom + small WC near entrance), kitchen-living-dining 40-55 m², dedicated laundry zone, often a usable terraza. Pre-war pisos give 3-3.5 m ceilings.
Three classic layouts. (1) Linear — bedroom → dressing → en-suite, all in a row, easy to ventilate, separate doors. (2) En-suite priority — bedroom + en-suite as the main pair, dressing carved as a corner. (3) Walk-through — dressing between bedroom and en-suite, used as a soft transition with no door. Núria draws all three on the visit and the family picks the one that fits how they live.
For a 4-bed family flat, no. Master en-suite (couple), family bathroom (kids), guest WC near the entrance (guests don't have to walk through the private wing). Drops nothing on resale, supports daily life when 4-5 people share the apartment. The third one is often just toilet + sink, 2-3 m², mechanically extracted, no daylight needed.
7×1 inverter or two 4×1 units typically. Master + bedroom 2 + bedroom 3 + bedroom 4 + living + kitchen + study = 7 indoor units. Outdoor unit on the terrace or rooftop subject to comunidad approval. If you go aerotermia we replace the AC outdoor with a heat pump that does heating + cooling + domestic hot water — pairs perfectly with underfloor heating in the new screed.
Base tier 10-12 weeks, Standard 14-18 weeks, Designer 20-26 weeks. Pre-war Sarrià with original mosaic tile to preserve, structural surprises (cast-iron baixants, irregular slab, beam reinforcement), or a heat-pump install with three-phase add 3-6 weeks. We commit to the timeline at contract signing and pay liquidated damages if we run beyond it without an approved variation.
