Three-bedroom apartment renovation in Barcelona
a master en-suite, two real bedrooms, and a family bathroom that frees the morning.
A 3-bed reform crosses two thresholds at once: three private zones to isolate, and a second bathroom that turns the master into an en-suite. Albert Soler has run 80+ of these. Núria designs the multi-zone HVAC. Typical 3-bed: 95-130 m² in Eixample or Sant Gervasi, master 14-16 m², two secondaries, kitchen-living open, often a small terraza.

About this service
Three private zones plus two bathrooms — the threshold change.
Going from 2-bed to 3-bed isn't just a third bedroom — it's the moment a single bathroom stops working. Master en-suite plus a family bathroom is the quiet upgrade that decides whether the flat works in the morning. We design the plumbing as two independent wet-cluster zones from day one.
02
Two wet clusters from day one
The master en-suite and the family bathroom are designed as two independent wet clusters with their own manifold. Pere reroutes the baixant where the master en-suite needs it, sound-insulates the drainage, pressure-tests both clusters separately. Result: zero noise transfer between bathrooms.
03
Multi-zone HVAC
5×1 inverter on the AC side with five indoor units (master, bedroom 2, bedroom 3, living, kitchen). One outdoor unit on the terrace or facade — comunidad approval handled. Optional aerotermia heat pump for low-temp underfloor across the whole flat.

Common 3-bed questions
Things owners ask before signing.
2-bed = two private zones, one shared bathroom typical. 3-bed = three private zones (master + 2 secondary), often with a master en-suite plus a shared family bathroom — the second bathroom is the threshold change. 4-bed = master suite + 3 secondary, usually 3 bathrooms, larger common area, and the MEP load steps up another level.
95-130 m² in Eixample, Sant Gervasi or Sarrià. Master 14-16 m² (queen + double wardrobe), two secondaries 9-12 m² each, master en-suite (toilet + sink + shower) plus a shared family bathroom (toilet + sink + bath), kitchen-living 30-40 m², often a small terraza. Pre-war pisos give you 3-3.5 m ceilings and original mosaic tile on the floor (we restore it where requested).
Yes for 3-bed flats. Typically a 5×1 inverter (Mitsubishi, Daikin, Toshiba) with five indoor units — master, bedroom 2, bedroom 3, living, kitchen. One outdoor unit on the terrace or on the facade subject to comunidad approval (vibration, noise, aesthetic). If you go aerotermia we replace the outdoor with a heat pump that does both heating and cooling.
For a 3-bed flat we usually do both — a master en-suite (toilet + sink + shower, no daylight needed if extracted properly) plus a shared family bathroom (toilet + sink + bath, accessible from the corridor). Frees the family bathroom in the morning, supports kids and guests, drops nothing on resale. Most 3-bed buyers expect both.
Base tier 8-10 weeks, Standard 11-14 weeks, Designer 16-20 weeks. Pre-war or large flats with structural surprises (cast-iron baixants, irregular slab, mosaic to preserve, reinforcement of an old beam) add 2-4 weeks. We commit to the timeline at contract signing and pay liquidated damages if we run beyond it without an approved variation.
In 3-bed flats we typically design the third bedroom as a flex room — sofa-bed plus desk plus fitted storage — so it serves both bedroom and study without needing a fourth bedroom. Or we carve a 3-4 m² work nook in the living room, daylit, with cabling for two screens and acoustic panels behind to dampen video-call echoes.
