Wood­en house on the Weser with RIKA pel­let stove

The Ahad family owns this small retreat in the fishing village of Heinsen in the middle of Weserbergland directly on the river bank. As builders and architects at the same time, they realised their very personal dream house – an interpretation of the unique cultural and landscape space, a smart building that uses resources moderately and wisely. And does so with the modern SONO pellet stove from RIKA.

When intelligent architecture meets ecological and sustainable construction, the result is something very special. Like the curved wooden building by Katja and Sascha Ahad with its high and narrow proportions, which fits harmoniously into the row of old half-timbered houses. Separated only by narrow alleys and located directly on the Weser, the challenges were mainly concerning fire safety and flood protection. A well thought-out construction that is fully reversible without leaving a trace, does not contain any harmful substances, as well as a careful selection of building materials, which are ecological and recyclable, are the basic framework.

The big picture and its details

Prefabricated walls made of water-impermeable concrete were used for the basement, natural spruce wood from the region is used for the supporting structure, façade and interior design, and the house was given a skin of clay tiles as weather protection. It has a large dormer facing west and the huge glass front on the river side, installed by hand, is undoubtedly the highlight. The windows and doors were made of oak wood, the joints sealed with hemp. Heating is carbon neutral and energy saving thanks to the SONO pellet stove, which was placed prominently in the centre of the house and thus supplies the entire building with pleasant warmth through the two-storey air space. Like all RIKA pellet stoves, the stove can be controlled by touch display and online, is economical in consumption, quiet, low maintenance and low in emissions. The wood pellets come from regional production, of course.

Retailer’s statement: “We connected the SONO pellet stove to an internal stainless steel chimney. The central positioning puts the fire in the centre of this exceptional wooden house.”
