Transformation Forest House: sustainable, compact and sculptural rooftop extension

Transformation Forest House sustainable, compact and sculptural rooftop extension (1)

The architect’s description – Transformation Forest House: On top of an existing 1950s holiday home, hidden in the forest, a sculptural, compact and sustainable rooftop extension climbs out of the original structure and seeks it’s way towards the great vista over the open grassland enclosed by the forest. The extension is situated within the leaves and feels like a secluded tree house. The design fits the restrictions stated by the municipality concerning maximum height and sloping roofs.

The existing house will be refurbished in a sustainable way based on full autarky. A new new off-grid solar system will provide in energy, a woodstove will provide warmth and wastewater that now ends up in a septic tank will be filtered by a halophyte filter. The rooftop extension will be almost entirely constructed out of timber, with flax insulation and all facades and roofing will be covered with untreated Larch cladding. Hanging stairs in the existing living room provides access towards the new compact extension.

The exterior and interior of the extension are tailor fit designed for the functions and usage. The beds and storage space are built-in so no further furniture will be needed. The rooftop extension offers space for two bedrooms and a landing with a wash table, which provides access towards the existing roof. The existing roof was already frequently being used as a secret place to enjoy the setting sun and the flora and fauna.
