Päivä Architekti transforms a hilltop home in the Czech Republic with a beautiful larch extension - A Modern Addition to the Czech Hilltop Landscape

I’ve spent a lot of time looking at how we build in fragile places, and there’s something genuinely moving about seeing a house that doesn't just sit on a hill but actually respects the dirt beneath it. When Päivä Architekti took on this project in the Czech Republic, they weren't just adding a room; they were trying to solve the puzzle of a 35-degree slope that would normally require a messy amount of concrete. Instead of tearing up the hillside, they opted for six steel micro-piles driven eight meters deep into the bedrock, which is a choice I really respect for its restraint. It’s a bit like acupuncture for the earth, honestly. To make the new larch extension feel at home, they treated the wood with an iron-sulf

I’ve always been fascinated by how choosing the right wood isn't just about the "look," but about how that material actually behaves when the wind starts howling across a Czech hilltop. When we look at the larch used here, it’s got this incredible density of about 590 kg/m³, which basically means it can take a beating from the elements without needing a bunch of nasty chemical preservatives. Think of it like a heavy wool sweater for the house; because larch has such low thermal conductivity, it creates this natural envelope that keeps the warmth in when the Central European winter gets bitey. What’s really clever, though, is how the team left a 40mm air gap behind those boards to create a chimney effect for passive cooling. They went with a vertical orientation for the

I’ve always thought the hardest part of any renovation isn't the new stuff, but how you actually hook it into the old bones without breaking anything. For this Czech project, the architects didn't just smash the extension against the original masonry; they used a narrow, recessed glass corridor that acts like a quiet handshake between two different eras. You're looking at triple-glazed units with a center-of-glass U-value of 0.5 W/(m²K), which honestly sounds like total overkill until you realize it's keeping the heat from escaping through what is essentially a glass bridge. Because the new timber frame is entirely self-supporting, it doesn't lean on the old house for help, which is a smart move to avoid the cracks you usually get when

I’ve always felt that the real test of a home isn’t how it looks from the driveway, but how it feels when you’re standing in the middle of the living room at sunset. Inside this extension, they’ve gone with a high-density, polished concrete floor that weighs in at about 2,240 kg/m³, which sounds like a lot of heavy lifting but it’s actually there to act as a thermal battery. Think of it as a sponge that soaks up the sun's heat during the day and slowly breathes it back out when the temperature drops at night. I'm not sure if it's just me, but you can’t really talk about this space without mentioning that massive glass wall, which uses specialized quadruple glazing to keep the Czech
