The financial advisor tells you that the budget for building a house adds up? I point out that many people still add quite a bit on top, which the financial advisor no longer notices. In 2019 on average: 2000€/sqm, according to the Energy Saving Ordinance, simple design, ETICS, plaster, without fireplace, sliding doors, lift-and-slide door, bay window or other frills Plus additional construction costs Plus garage/carport Plus painting and flooring Plus outdoor facilities Plus furniture (kitchen) How this relates to [SA], I don't know – in [BB] many things are still very cheap. Regarding the floor plan: The 3.15 meters are indeed quite tight. For 2 festive weeks, I personally wouldn't want to give up 50 weeks of space in the TV corner. You should also see with four people how you watch a movie on the sofa. But they are not only very tight in the living area. Also in the kitchen: 60cm kitchen line, 1 meter passage, 90cm island, that makes 2.50 meters. Practically 60cm remain for a theoretical seating area. With the elongated kitchen dimension, you should also use the length for the seating area and such. Fireplace: where it is now, its warmth hinders the seats on the right side of the plan. The heat will even singe the chair backs. I bet on that! It is better situated at the right corner of the all-purpose room door. The utility room has a good size. I find the wardrobe too small for 4 people. Upstairs there is similar space wastage in the hallway. However, I find the 3 children's rooms or office well arranged. Fundamentally, it surprises me that you plan the garage in the west. It is much better placed in the east. Nevertheless, if laundry is done for 4 people in the utility room, I would give up a direct passage. Issue of humidity in the utility room: ventilate, manually or by system. What's in a shelf also fits in a kitchen cabinet. Since the plot/building area is very large, I would also set the house a bit further back. A 5 meter forecourt offers space for playing, lingering, bicycle repair, etc. 3 meters offers almost nothing.
