An eye-catcher from inside and outside

Duo 225

In this design, the main apartment is located in a two-storey villa with a hipped roof. The granny flat is housed in a separate, single-storey extension with a pent roof. Since the granny annexe stands on its own in terms of planning, it can also be easily adapted to other property designs and scheduled accordingly. In the main apartment there is space for almost 90 m² of living space on the ground floor. The dining area can be expanded with a small extension. This planning option makes the dining area appear even more spacious and also spices up the house from the exterior.
