Terra Bianca
Five identical prefab SiP-frame villas sit side‑by‑side on a sunny hillside above the Neretva. Each one is built to the same spec, so once you understand a single house, you understand them all. Below you'll find the essential numbers plus the engineering choices that make the homes warm in winter, cool in summer, and simple to run.

How the Shell Works
Prefab SiP frame
Factory‑cut laminated posts and beams craned into place in under a week, so walls stay square and waste stays low.
Wall build‑up
180 mm mineral wool, OSB, vapour-open membrane, ventilated cavity, finished in ThermoWood cladding that needs no chemical preservatives.
Roof
220 mm mineral wool under a ventilated standing-seam aluminium skin; rain drains fast, snow slides quietly.
Windows
Seven-chamber alu-PVC frames with triple-glazed, argon-filled glass.
Air‑tightness goal: ≤ 1 ACH at 50 Pa, proven by blower‑door before hand‑over.
Comfort Systems in Three Lines
- Heat and cool with a single inverter heat‑pump: warm floors in January, quiet fan‑coils in August.
- Fresh air via MVHR at 85 % heat recovery—no stale bedrooms, less dust.
- Hot water from the same heat‑pump plus a solar roof loop; showers keep flowing even after pool time.
Pool and Outdoor Kit
Salt‑water chlorination means gentler skin and no chlorine smell. A slatted polycarbonate cover captures solar heat and adds 4‑6 weeks to the swim season. Garden taps run on a 3 000 L rain‑water tank tucked under the deck.
Floor Plan in Plain English
- Living and kitchen (41.2 m²) open south‑west to the terrace.
- Three bedrooms (10.8 m², 9.7 m², 8.1 m²) cluster off a quiet hall.
- Main bathroom holds a walk‑in shower and dual‑flush WC; a guest WC sits by the foyer.
- Utility room hides the heat‑pump, MVHR and laundry stack—out of sight, easy to service.
Material Highlights & Key Performance Metrics
ThermoWood cladding
Heat-treated pine with 40-year lifespan, fully recyclable.
Standing-seam roof
Aluminum alloy with 30-year finish guarantee.
Rigips double-board interior
Provides 45 dB sound reduction, keeping neighbor noise outdoors.
Stored carbon
Approximately 55 t CO₂ sequestered in each villa's prefab SiP frame.
Operational CO₂
Projected at ≤ 14 kg/m²/yr due to excellent insulation values and efficient heat-pump.
Why It Matters
You get a house that handles Herzegovina summers without rattling AC units, and Bosnian winters without oversized boilers. The salt‑water pool needs little upkeep, the prefab SiP walls sequester more carbon than they cost to build, and the EV conduit waits for your charger, not the other way round. In short, these numbers translate into quieter living, lower bills, and a feel-good footprint, leaving you free to focus on river swims, waterfall hikes, and local day trips.
