Jizerka Chalet
A cottage in the heart of a mountain settlement characterized by its dispersed development along the Jizerka stream.
A house with a long history - evolving from a traditional borderland farmhouse to a lodging house for forestry workers, then a guesthouse with a tavern, and finally its current form as a cozy family retreat.
The design concept is based on two fundamental approaches. The first is the sensitive reconstruction of the original timbered residential part and the stone-built ground floor. The second is the addition of a new attic space with a minimalistic aesthetic.
Later, incongruous additions that disrupted the traditional floor plan were removed, the timber structure was dismantled and meticulously reassembled, and the massive granite masonry was carefully cleaned.
The ground floor interior is built on basic natural materials - solid wooden plank floors, a beamed ceiling, exposed and restored timber walls, a simple tiled stove with a white-plastered heated nook, a large dining table.
The attic follows a contemporary design approach. The floors are made of solid wooden planks, the gable walls are finished with white-painted clay plaster, and sloped surfaces are lined with large-format bio-boards, with built-in furniture made of the same material. The result is a generous, clean, and bright space filled with the scent of wood.
The entire concept is complemented by a separate timber store with an outdoor sauna. A utilitarian rectangular structure with a gabled roof without overhangs, wooden cladding. A large glazed surface provides a view from the sauna.
Adjacent to the sauna is a wooden terrace with an integrated cooling tub.
The outdoor seating area is set on dry-laid stone paving.

The building is heated by a ground-water heat pump.
