House Design
Planning by:
- Designer from a construction company
What do you particularly like? Why? All room wishes have been fulfilled, open space in a good position with large windows

What do you dislike? Why? Corridor too long, cloakroom too far from the entrance, terrace access only around the corner behind the dining area (but there are two large sliding doors there), utility room without a window, kitchen only accessible through the living room, planned swap of utility room with guest room, little storage space in the living room

Price estimate according to architect/designer: $630,000
Personal price limit for the house, including fittings:
Preferred heating system: air-to-water heat pump

If you had to give up, which details/extensions
- can you give up: straight staircase
- cannot give up: 2 offices

Why was the design made the way it is now?
All room requirements were fulfilled but the layout is not yet optimal. Modern look (especially the southwest house corner)

What makes it particularly good or bad in your opinion?
Lots of wasted space, long corridors, uneven room sizes, limited storage in the living room, blocked access to the terrace
