A made-to-measure Doppeldreieck sun sail, precisely planned and exactly matched to the setting.
The sail spans the terrace and shields both the outdoor area and the rooms behind it from direct sunlight. At the same time, the view out stays completely clear.
Control is fully automatic:
In the morning the sail extends via the sun sensor, in the evening it retracts again. The system is rounded off by wind monitoring for extra safety.
Particular care went into the architectural integration. The brackets were fitted in several steps and then clad in wood, so they blend harmoniously into the façade.
The structural elements – posts, uprights and brackets – are kept in anthracite and recede visually. This creates a shading solution that reads not as a technical element but as a natural part of the house.
The sun sail not only reduces the heat on the terrace but noticeably improves the indoor climate throughout the living area. The large glass surfaces stay clear – with no lowered blinds or intrusive shading elements.
The outdoor space becomes a true living space: sheltered, calm and usable at any time.
The sail extends automatically in the morning and retracts in the evening. This is controlled by the light and wind sensor. In a storm with wind over 20 m/s the sail retracts automatically.
Master craftsmanship from the Allgäu
For over 20 years, Thaddäus Berktold has run his carpentry in the Allgäu with a clear focus on sustainable craft and alpine building culture. Be it a classic roof truss, a mountain hut or the renovation of the Jägersberg – his work unites traditional methods with modern architecture, precision and ties to the region.
Project highlights
Shade without losing the view
The Doppeldreieck sail shades terrace and interiors without limiting the panoramic view of the Allgäu Alps – the view stays clear.
Part of the architecture
Posts and brackets in anthracite, clad in wood, recede visually. The shading reads not as technical, but as part of the house.
Fully automatic with wind sensor
Sun and wind sensors control the sail: it extends in the morning, retracts in the evening. In a storm over 20 m/s it safely rolls back in automatically.
Better indoor climate
The sail lowers the heat on the terrace and in the living area – with no blinds at all. The large glass surfaces stay completely clear.
