Mucuc18Hello dear house building forum community!
After carefully reading along for a while, I would now like to share our current design for constructive feedback.
Below are the usual details; south is at the bottom of the site plan:
Development Plan / Restrictions
Plot size | 512sqm (5509 sq ft)
Slope | No
Site coverage ratio | 160sqm (1722 sq ft) building footprint allowed for main building (+140sqm (1507 sq ft) overrun permitted for other structures)
Number of parking spaces | min. 1.5
Roof type | SD / WD or similar (mansard roofs are common in the area)
Maximum heights / limits | Ridge height 9.4m (31 ft) | Eaves height 6.5m (21 ft)
Additional requirements | Setbacks of 0.4 times the building height on two sides, 0.8 times the building height on other sides
Client Requirements
Architectural style, roof shape, building type | classic mansard-hipped roof, somewhat modern interpretation
Basement, floors | Ground floor, first floor, attic + basement
Number of occupants, ages | 2 (30 yrs, 33 yrs) + 1 (0 yrs) + occasional visitors
Space needs on ground floor, first floor | approx. 80–90sqm (860–970 sq ft) each for ground and first floors
Office | 1 office space needed for home office
Guest accommodation per year | to be determined, sometimes longer visits
Open or closed layout | rather open, but with adequate sound insulation and privacy
Conservative or modern construction | rather modern
Open kitchen, kitchen island | large open kitchen with island is important
Seating for dining | 4–6 seats regularly available, with option to extend
Fireplace | yes
Music / stereo wall | no, flexible hi-fi system
Balcony, roof terrace | no
Garage, carport | double garage
Utility garden, greenhouse | garden with beds and 2–3 trees, enclosed by hedge
House Design
Planner: architect & own ideas/drawings
What do you like most? Why? Separate parents’ floor, spacious open living area, straight staircase, number of rooms on first floor (flexibility), sufficient wardrobe space, staircase separated from living room
What do you dislike? Why? Location possibilities for heat pump outdoor unit, attic possibly has somewhat excessive space that might not be used efficiently (sloping ceilings)
Cost estimate by architect/planner: none so far
Budget for house including equipment: 1.4–1.5 million
Preferred heating technology: air-to-water heat pump
If you have to give up something, which details/features
- can be omitted: fireplace, pool, possibly double garage
- cannot be omitted: preferably a “large” garden
Why was the design developed this way? For example,
A mix of own ideas and architect’s input, along with several rounds of improvements over recent weeks. The main focus is on maintaining as much contiguous garden space as possible on a relatively small lot. Therefore, a setback on the east side is planned to comply with setbacks on the trapezoidal plot. The three floors plus basement help keep the house footprint small and separate the parents’ area from the children/guest area. We feel our wishes are well implemented in the current floor plan. Minor details such as window dimensions still need adjustment (e.g., equal-sized windows on the first floor west side, possibly a slightly larger sliding door on the ground floor, etc.).
What is the most important / basic question about the floor plan in 130 characters?
Do you see potential for improvement that we should consider or any no-gos we need to rethink? We are quite happy with the current status but appreciate input on aspects we may have overlooked or rationalized too optimistically.

Do you see any areas for improvement that we should consider or any absolute no-gos that we should rethink? I won’t comment on the floor plan since others have a better overview. But this roof design is really a no-go nowadays, as you can hardly fit any photovoltaic panels on it.

But this roof style – nowadays it’s really a no-go, since hardly any photovoltaic panels fit on it. Finally, a mansard roof – and in both dimensions!
Its rarity nowadays is mainly due to thoughtless zoning regulations that have practically wiped it out. In principle, this roof type is actually the best to optimize for photovoltaic systems.

Price estimate according to the architect/planner: none done so far You really should get that done… that’s quite a sum: the mansard roof counts as a full finish of the tight 80 sqm (860 sq ft).

House price limit, including fittings: 1.4–1.5 million Oh, I’m just reading that now. Well, then 🙂

Space requirements on ground floor, upper floor | about 80–90 sqm (860–970 sq ft) for each, ground and upper floor Mucuc18 schrieb:
The attempt to keep as much contiguous garden space as possible on a rather small plot. Keep in mind that your large driveway will reduce the garden space again.

No-gos we should reconsider? Well… the roof might be liked by some. But it fits the so-called coffee grinder style villa. I wouldn’t call it modern.
No-gos for me are the guest toilet behind the wardrobe, the bathtub in the master bedroom area instead of the children’s section, a shower door in the kids’ bathroom (who's going to clean that?), and kind of a major planning mistake: the lack of ceiling height in one corner of the bedroom (lower left corner of the bed and roof slope). A 1.90 m (6 ft 3 in) tall man definitely has to duck to get through there without hitting his head.
I find the roof shape quite unique, and regarding the photovoltaic system, it’s definitely worth considering integrating the panels as "roof tiles." No budget was mentioned 😉 ... @ypg just discovered it ... so, probably okay.
I like the floor plan overall. For the kitchen, I would suggest a detailed plan, as the divided wall to the hallway needs careful consideration. Also, I would save the open space above and instead install the washer and dryer on the "children/guest floor."
I agree with Yvonne about the bedroom bed edge; however, I would probably just rotate the bed 90° and place the headboard against the right wall on the plan.
Having a bathtub only in the larger bathroom doesn’t bother me since that bathroom is accessible via the hallway. A shower door in the children's bathroom could just as well be a shower curtain, or if preferred, a proper door. The phase of having kids and a bathtub isn’t usually very long, especially in the early years when parents are often not around.
There is simply a lot of space ... is there really that much hobby activity to fill so much basement?

I see the bedroom bed edge the same way as Yvonne does, but I would probably just rotate the bed 90° and place the headboard against the right-hand wall of the floor plan. It is now 2.54 meters (8 feet 4 inches)… the other side can only be estimated. I think it’s almost the same?
