Designed by Prague studio ASGK Design, Energy Efficient Wooden House Zilvar occupies a site surrounded by fields and forest on the outskirts of the village in the eastern Bohemia region.

They also specified the use of wood.


In response, the architects created a house with a larch timber frame, completely clad in vertical planks of larch that have been burnt and stained to make them more hardwearing.

Large openings on the ground floor levels feature sliding glazing to open up the house when the weather is good and make the most of the heat from the sun in winter.

“A microclimate of frequent rain, strong western winds and the eastern sun was taken into account, together with the need for calm and peace, away from the busy, modern world, to make the ideal year-long living,” said the architects.

The house features a roof with multiple slopes in different directions, which gives the building its unusual shape

This arrangement creates two separate bedroom areas on the upper levels at opposite ends of the house, accessed via industrial-style staircases. The open-plan ground floor encompasses a lounge area, kitchen and dining space.

The architects designed a number of features to fulfil the energy efficiency requirements of the clients, including an outer- and inner-wall structure that allows vapour to diffuse through the building. The house is slightly raised above the ground to aid climate control.

Completed in 2013, Energy Efficient Wooden House Zilvar was one of the winners in the private houses under 1,000-square-foot category at the 2016 edition of the Architizer A+Awards, which promotes and celebrate the year’s best projects and products.
