SPA and conference building in Uppgrenna, north of Gränna with a mile-wide view of Lake Vättern and Visingsö. An existing falu red barn is demolished and replaced by a modern building with a ground floor partly buried in the slope. The upper entrance level consists of an insulated building together with an unheated greenhouse that extends over the entire roof with space for plantations and protected terraces. There is a mile-wide view from the greenhouse which also creates an internal climate corresponding to northern Italy.
The exterior is inspired by traditional barn architecture with its simple gates and shutters. All windows and doors are provided with openable shutters in the same rough, falu-red panel as the wall. It creates dynamics for the facade and reduces heat radiation when the house is not in use.
The greenhouse enables a closed local cycle with plant beds that reuse the water and purify and absorb the nutrients in the wastewater and convert it into fruit and vegetables. The house is not connected to the municipal sewer system.
The house was nominated to the Swedish award "Rödfärgspriset" in 2016.
It recieved the Environmental Award of the City of Jönköping Jönköpings kommuns Miljöpris) in 2016.
