Hello everyone,

We are a family of four living on the upper floor of a multi-family house (4 apartments) that we own. Since space is becoming tight and the ground floor apartment is becoming vacant, we would like to expand by connecting the two apartments stacked on top of each other on the garden side.

In the past, considerable renovation and remodeling have already been done on the house. This includes changes to the upper floor layout, installation of underfloor heating throughout including tile flooring, replacement of all windows, roof insulation, balcony refurbishment, and replacement of apartment entrance doors, the front door, and garage doors.

For now, we are primarily focused on the ground floor, where we want to create more space. I have attached the current floor plans (G1). Additionally, I uploaded the plans of the entire house (ground floor + upper floor), which do not fully match reality. For example, the open patio was never realized but was built as a type of conservatory. The plans show the two apartments on the right side.

In the next two posts, I will describe the planned changes.

A friend of mine has now opened up his living space and installed a double T beam for support. He left it exposed in a vintage style, and the cast concrete floor looks really cool.
