Nový stav Ester Havlová, původní stav Matěj Barla |
The extension to the existing building relates to the western half of the semi-detached house, one of the oldest buildings on the site, with an extension to the south side. The renovation and the garden extension were to be carried out with respect to the owners who built the house, according to the wishes of the investor. Conceptually, the reconstruction was to preserve the atmosphere the investor remembers from the times of childhood games at grandma and grandpa's house. Therefore, the design respects the existing building and its architectural design, where from the beginning a ground floor vestibule with a bathroom was attached to the main structure. However, the ground floor part of the vestibule extension has undergone a layout change and has been extended with an extension that extends the built-up area towards the garage. The original house has been newly extended but with contextual retention of the shape and appearance of the façade. This has allowed the creation of a new room and bathroom on the first floor. On the ground floor of the original mass, only the position of the entrance to the house will be changed.
The extension for the dining room and living room on the south side of the building is conceived as a completely new mass, glued to the existing building. The form of this extension was created by breaking the flat roof into a negative shape. The modelling of the roof thus allows light to enter the staircase.
On the newly insulated façade of the old part of the house, the original motif of the admitted lattice masonry in bands and around the windows is repeated. The new extension is designed in ceramic brick banding throughout, as an allusion to the structural decorative elements of the original house.

The technical solution maintains and follows the original concept. It is a brick building with a load-bearing brick structural system, wooden ceilings and a wooden roof. The wall surfaces are plastered. Heating is by central heating with radiators and convector heaters. The building is heated by a gas condensing boiler. Insulation of the building with a plaster surface and the use of ceramic tiles, which are as close as possible to the appearance of the original facade, allowed to preserve the original building and at the same time significantly improve its thermal technical parameters. A distinctive element of the interior, the authentic wooden staircase, which has undergone an arts and crafts restoration, has been extracted from the modern adaptation.
