a family-led group, on the market since 2013.

“Our SIP shell stood in ten weeks, and we moved in after nine months. First winter's bills were a quarter of our Budapest flat — the heat pump and solar work together exactly as promised.”

“Our Solymár logistics hall was handed over turnkey four days before the contractual deadline. A six-month run is rare here at home — without their in-house equipment and weekly site management, it would not have happened.”

“We arrived at the first consultation with our plot and no concept. Two weeks later they presented three parallel sketches — each one felt like a conversation about our lives. Choosing wasn't about variants; it was about direction.”

“We bought our new home in the Sparta House park — plot included, turnkey. Design, build, and handover under one contract; on move-in day the heat pump was running and the garden was edged.”

“Our restaurant's full interior remodel in three weeks — they didn't build the shell, yet the kitchen, the seating, and the façade came together as if planned from scratch.”

“We're a family with two kids who built a 160 m² SIP home. The schedule never slipped, and the construction plans updated in real-time on the portal each week. The calendar reminder before each weekly site visit is a serious quality touch.”

“Our Telki villa's general contracting needed complex structural work due to the sloping plot. Szilárd Erki visited personally for every harder decision, and the proposed solutions always came from the architect-and-engineer consensus.”

“While our neighbour was still laying brick, our SIP shell was already sealed and our blower-door reading came in at 0.4 n50. Electrical and HVAC then finished within thirty days. Anyone starting to build now: don't plan on brick.”

“After two years of searching, we found the Sparta House Budakeszi project. Nothing was promised that didn't fit the timeline or the budget. At handover they flagged details that with another developer we'd have only noticed six months in on our own.”

“We brought them in for a flat refurbishment — not their typical contract, but their interior team treated us with the same care as a family-home client. The finishes were chosen together, on-site.”

“We built a 95 m² SIP home for our parents in retirement. Single-storey, accessible, maintainable. Six months after warranty we contacted them about a window-sealing issue — a technician was on site within a week. That shouldn't be underrated.”
