The OneTwoHouse is a detached house that creates an optical illusion with its external shape: although it looks like a semi-detached house, it is actually a single detached house. The offset cubes and the symmetrical façade create the impression of two separate units, which are nevertheless united under one roof. The spacious first floor houses the public areas of the house and opens generously onto the garden. The high rooms and the delicate wooden ceiling create a light, inviting atmosphere that makes the transition to the private area on the upper floor smooth and harmonious. The carefully positioned window openings frame the outside space and create a strong connection between inside and outside. The family's private retreat is located on the upper floor. Here, the bedrooms are deliberately kept compact to ensure an intimate, cozy atmosphere. The large hallway area acts as a lifeline that connects all the rooms and offers the family members space to meet and retreat at the same time. The name OneTwoHouse not only describes the external appearance of the house, but also the feeling of unity and reciprocity that can be felt inside the building. The architecture conveys a balance between the feeling of openness on the first floor and tranquillity on the upper floor. This fusion of two seemingly separate worlds under one roof is reflected in the details of the house.

The OneTwoHouse is more than just a house. It is a space that, with its design and functionality, creates a link between the external appearance of a semi-detached house and the internal structure of a detached house. It unites both worlds under one roof - and thus offers a home that is both open and spacious as well as private and cozy.

SUSTAINABILITY

The building is constructed from Proton plane bricks with a perlite filling using the thin-bed method. This means that the bricks are easy to dismantle and can be reused as part of the circular economy. Concrete was largely dispensed with in the construction. The frost apron of the floor slab was constructed with foam glass gravel. A geothermal probe system with heat pump supplies the building's underfloor heating and is supported by an all-roof PV system with battery storage. The northern roof surface is designed as a sloping green roof and offers excellent insulation properties as well as biodiversity. The building is insulated to low-energy standards. There will be no controlled ventilation. Fresh air is to be supplied manually by opening the windows. Thanks to the clay plaster surfaces and clay building boards, the interiors have a very high moisture storage capacity and thus contribute to the natural air conditioning of the room air.
