sip panel homes
SIP technology is a sealed PUR insulating core between two OSB faces — structure and insulation in one element. Factory-manufactured panels that stand in 8–12 weeks, with near-passive-house performance and class BB+ energy rating.

A SIP home is a coordinated system of eight to ten layers. The table shows the base-package layers — mid and premium add further enhancements.
type plans
Any type plan can be sited on the client's plot — under general contracting. Within the type, façade, interior design, and garden layout are shaped together with the client.

sip-specific questions
A SIP (Structural Insulated Panel) is a sealed PUR or EPS insulating core between two OSB faces — structure and insulation in one element. Panels are produced under factory conditions, so on-site assembly is fast and precise. The full shell stands in 8–12 weeks.
Our standard SIP wall delivers a U-value of ≈ 0.15 W/m²K, which is near-passive-house performance. SIP homes we deliver typically reach class BB+ — annual primary energy demand of 60–70 kWh/m²/year, paired with a heat pump and solar array.
Including slab and turnkey delivery, 8–9 months. The shell itself stands in 8–12 weeks with manufacturing running in parallel. The remainder of the time goes into building services, interior fit-out, and the garden.
The exact price depends on size, orientation, building services, and finish level. Indicative range: 650 000 – 800 000 HUF/m² for entry-level finish, 900 000 – 1 200 000 HUF/m² for premium. After a quote request we provide a concrete itemised offer within 10 working days.
SIP panels meet Hungary's fire-protection regulations (OTSZ) when combined with the appropriate fire-rated finishing layer. A standard SIP wall with interior gypsum-board finish reaches F30 or F60 classification. Regulatory specifics are reviewed project-by-project at permitting.
SIP panels last 80–100 years given appropriate external protection (render, timber cladding) and roof maintenance. We provide a 10-year structural warranty, 2–5 years on building services (depending on manufacturer), and a mandatory year-end technical walkthrough.
