Winner: House extension of the year 2025. Jan Henrik Jansen Arkitekter and Studio Marshall Blecher have restored and extended a modernist summerhouse, Vejrhøj, in Fårevejle, Denmark.

Jan Henrik Jansen Arkitekter and Studio Marshall Blecher breathe new life into Ole Meyer's iconic 1967 modernist masterpiece, improving the performance and size of the original and adding a significant extension.

The original timber structure was carefully rebuilt and extended, meeting contemporary standards while retaining its character and craftsmanship.

Inspired by long-lost 1960s sketches by Meyer, a new concrete volume was embedded into the hillside behind the house.

Echoing the original roof form, it introduces a contrasting palette of board-marked concrete and pine. A sunken courtyard connects the two, creating a sheltered outdoor space.

The result is a bold yet sensitive evolution of Danish modernism, uniting old and new in a cohesive architectural dialogue.

Judge comments: "Born of an extremely interesting story, this renovation and extension continues the life of an acclaimed 1960s summerhouse. Mimicking the original building, the addition holds all the principle of the original without being a direct copy to start a conversation between the two structures and continue its story."
