Architecture & planning services

Our company’s Design Team is responsible for planning our building objects. Our architects are able to utilise the free advantages nature offers; passive solar energy, natural landscapes and flora, and gravitational ventilation. Our engineers solve structural challenges and plan technical functionality for the customer’s benefit. We plan both single family homes and larger community housing concepts.
New buildings

New buildings

We build single homes and larger complexes, such as housing areas, retirement homes, schools, and high-rise buildings, with love.  Both official and private objects deserve to be built with a focus on quality.


We repair and restore old buildings with natural materials. We exchange logs, renew floors, repair roofs and improve insulations. We also carry out renovations and extensions with breathable and safe materials.
Clay and lime plastering

Our beautiful clay plasters are ideal for indoor air quality and esthetically pleasing. Our skilled plasterers can create both unique effects and even surfaces in the colours you wish.

We sell chemical-free, safe and healthy building material from our office in Billnäs. Our products include ready-to-use clay plasters, clay paints, reed boards and mats and unburned clay bricks.
