Located on the outskirts of Berlin, this former farmstead dating from 1873 was originally built by colonists with little land. Following consultation with the conservation authorities, it was agreed that the most economic option would be the best solution – to demolish the existing building and rebuild it in the original style.

Old and new reunited

The result is a modern family home with historic charm, in which old and new features are reunited. The entrance door, transom windows, half-hipped roof and stone plinth were reconstructed in accordance with historical details. The clients wanted a both natural and highly insulated building envelope. They opted for Perlite-filled clay blocks from Wienerberger's sister company Schlagmann Poroton.

Modern and traditional

Passing through the timber front door, you arrive in the hallway, a typical feature of these smallholders' houses, which has been integrated into the new house in compliance with conservation regulations. Leading off from the hallway is a granny flat and access to workrooms and the kitchen. The whole of the ground floor has a bright and generous appearance due to the open doorways. The exposed brickwork in the arches was salvaged during the demolition, and confers more than just a rustic character to the building. All in all, a wonderful unique example of traditional brick architecture has been recreated. The roof space has been converted in a contemporary studio style. The living and bedroom and modern bathroom with wood-heated sauna are now located on the first floor.
The floors are tiled throughout the house, the ideal solution for the underfloor heating system, which is heated by a gas-fired condensing boiler. When coupled with a building envelope from energy-efficient clay blocks this guarantees low running costs. In addition to having excellent sound insulation properties, the cellular blocks also provide pleasant room conditions: Fired clay and the Perlite filling do not give off any harmful substances. This aspect was particularly important to the young family. Clay blocks are also the preferred choice when it comes to fire protection. The long-life building material has the ideal characteristics for a further 200 years in the new smallholder's house. This rebuild project is an impressive demonstration of the fact that tradition and modernity are not necessarily mutually exclusive. The listed building conditions were satisfied while still creating modern, high-quality living space.
