House Design
- Architect

What do you particularly like?
The existing layout, storage space under the stairs, three possible children’s rooms, bay window in the living room, exposed steel beams in the kitchen and living room, textured clinker brick facade, overall style of the house

What do you not like?
So far, there is no natural light in the stairwell, which is why there is a desire for a partially open roof structure

Preferred heating system:
Geothermal

Why is the design as it is now?
The architect has fully followed our specifications and wishes

What is the most important/fundamental question about the floor plan?

Would a partially open roof structure be possible? Do you have any experience with this? Do you have alternatives to Wittmunder torfbruch clinker? If yes, where did you get yours?
