A unique renovation project, LichtAktiv Haus transformed a box-like, closed structure into an open group of spacious rooms flooded with natural light. The LichtAktiv Haus can be realised in different variants - basic modernization and in modules according to financial ability, energetic ambition and need for extra square metres in the extension.
The present building contains two children’s children's rooms, two bathrooms, a master bedroom, a central living area and a reading room. All rooms feature façade and roof windows that are positioned to ensure optimum distribution of natural light – and the home’s window area was increased from 18 m² to 60 m². Living area has been closed by a five-metres-long glass wall, which could be opened to the home’s garden. Everything is also extended for an open living room connected with a dining room. Also kitchen and utility room has been implemented here. Porch became a link between what is old and new. To provide electricity and hot water solar collectors and photovoltaic solar selles were used – everything to cover energy demands of the house.
The concept of LichtAktiv Haus was based on the "settler spirit", but instead of self-sufficiency in terms of food, the home is self-sufficient in terms of energy.
The approach used for this project is a basic way to modernise an existing building without
having to make major changes to the building structure, as only the facade is renovated
to make the building more energy efficient. The building stock is left in its original state, receiving only a new roof with roof windows which offer adequate daylight in the upper floor. Furthermore, solar collectors are being installed on the roof.
The interior of the building is organised more efficiently and provides generous space. The old extension is transformed into a kitchen and living space, creating a new entrance area as well as generous views onto the large garden.
The basic structure of the existing building and modular extension are the same as the LichtAktiv Haus, and different in size, materials, and technology. The modular modernisation part consists of an extension. Consisting of a timber frame construction, it allows a flexible modernisation in terms of length and its configuration depending on individual needs. Thus, the occupants are free to design and extend their house as well as to choose the material to go between the timber frames. The main difference to the LichtAktiv Haus is the use of technical equipment and the choice of the materials. The building is efficient in terms of the use of energy and space, and it opens the living area onto the garden.
