ᐅ Floor plan of a narrow, long house (7 meters wide) with a gable roof

We have a special challenge and have purchased a plot of land measuring 12m x 45m (39ft x 148ft), on which we can build 7m x 15m (23ft x 49ft). The design must be a single-story building with a gable roof, a knee wall of 1m (3ft), red brick facade, white windows, and a maximum roof pitch of 48 degrees.

The goal is a modern construction style with an open floor plan downstairs, as much as possible.

In addition to two children's rooms (ages 1 and 3), we also need a home office/guest room. There will be no basement. After several attempts working with construction companies and architects, we have now found a direction and would like to get your opinion.

What do you think? We have two main questions: How can we arrange the living room and kitchen in a practical way, and how can we avoid feeling too cramped in the attic? The kitchen should also be larger (longer), with the office/guest bathroom narrower as a result. The staircase will be a concrete staircase including a storage room with a door to the hallway to create more space for a coat area. Upstairs, the bedroom will be narrower to make room for the bathroom and gallery. The window distribution is also not yet ideal. An air-to-water heat pump is planned. The hallway is small, but so far there has been no better solution.

If anyone has alternative ideas for a floor plan within these parameters, we would be very grateful.

South is at the top of the plan. The living room faces west, and the street is to the east. The neighbors are located to the south and north along the long sides, each with a 2.5m (8ft) distance.

The floor area ratio and site coverage ratio are strictly regulated, but since we are in detailed discussions with the building authority and expect to receive a special permit, these points can be set aside here.
