We are currently in the middle of planning our single-family home. There is an existing house built in 1965 that will mostly be demolished, but the basement will be retained and expanded. According to the current plan, a few exterior walls and the stairwell will remain.

Development Plan / Restrictions
Plot size: 950 m² (11,000 sq ft)
Slope: yes, rising approx. 7 m (23 ft) from the access road to the end of the property
Site coverage ratio: N/A
Floor area ratio: N/A
Building envelope, building line, and boundary: see plan
Setbacks: 3 m (10 ft) to the west, taken into account
Parking spaces: N/A
Number of levels: Basement + 1.5 floors
Roof type: Gable roof, 25 degrees
Architectural style: Modern single-family home
Orientation: View towards street/north, at the end of a cul-de-sac
Maximum height/limits: Eaves and ridge heights specified, matching neighboring buildings

Owners’ Requirements
Style, roof type, building type: Modern 1.5-story single-family house, approximately 250 m² (2,690 sq ft) with gable roof

Basement, Floors
Number of occupants: 3 (possibly +1). 2 adults, 1 child (2 years old), maybe another child later.
Office: Family use or home office? Home office
Overnight guests per year: rather few, not a priority
Open or closed layout: Open layout
Conservative or modern construction: Modern
Open kitchen with cooking island: Open kitchen with cooking island
Number of dining seats: 8
Fireplace: yes
Music/sound wall: no
Balcony, roof terrace: Covered outdoor seating area
Garage, carport: Currently planning 3 garages, 2 mandatory

House Design
Who designed it: Architect

What do you particularly like? Why? Open living spaces, pantry, separate children’s area including entrance and bathroom. Upper floor for parents. Entrance in the basement with wardrobe at street level, open atrium.

Cost estimate according to architect/planner: approx. 1.5 million EUR (all inclusive, also built-in furniture, lighting, landscaping, etc.)
Personal budget for house and fittings: manageable as planned
Preferred heating system: Heat pump

If you have to give up anything, which details/extensions
- Can you give up: Atrium
- Cannot give up: Home office

Why is the design the way it is now? For example:
Due to the size of the plot and the restriction of not being allowed to build two full floors, the basic idea is to build as much area as possible on the ground floor. The eaves heights are given and significantly restrict the attic, so the children’s area in the attic was discarded. Storage (utility space) is also important so it does not reduce the ground/upper floor living space. Currently, this means about 240 m² (2,585 sq ft) of living space + 100 m² (1,075 sq ft) of utility space (including a granny flat) + 3 garages.

The atrium is certainly a matter of taste. We plan to fully glaze it towards the upper floor (to reduce noise and odors), but want the ground floor to feel airy. However, due to maximum height restrictions, we cannot build as high ceilings on the ground floor as we would like. Currently, there is a small child who will initially occupy the attic in the office/guest room. Rooms for children 1 and 2 will initially be used as playroom and office. When the child is older, they can move to the area with their own bathroom. If there is only one child, possibly one room per child. In the basement, there are an additional approx. 50 m² (540 sq ft) of living space with shower and toilet as a granny flat, which could be another option for child 2. Currently, this is used as a fitness/hobby room.

On the plans, north is roughly towards the bottom. Overall, we like the design very much and have already gone through several scenarios and optimizations—but we would be grateful for any further feedback.

Could you explain that in more detail? I’d like to fully understand the idea.

With an impressive 73sqm (786 sq ft) allocated for the open-plan living area, you’re left with only a measly 12sqm (129 sq ft) for the planned children’s bedrooms.
(As for other elements like the basement, those can’t really be mentioned due to already stated reasons.)
Don’t get me wrong: I believe a child or teenager can manage well in 14sqm (150 sq ft), but in relation to your overall expectations, this doesn’t add up. The approach to the children’s bedrooms feels indecisive. Others build beautiful homes of around 160sqm (1,722 sq ft), have a spacious and airy 50sqm (538 sq ft) open-plan living area, and still manage to provide decent children’s bedrooms of about 15sqm (161 sq ft).

“Visual clutter” upstairs or “holes”

That’s exactly what can be said about the dining area.

Congratulations. Your architect has put some good thought into the renovation. I really like that.

I think it’s nice to consider partially preserving the existing structure. However, this creates many constraints that I wouldn’t want to follow given the budget. Shall we give a point for sustainability?

I think the glass wall overlooking the open space is a good idea.

I would have even given two points if it weren’t for the extensive extension. Two hundred forty square meters (2,583 square feet) seems weakly justified with the expectation of a possible second child, and the parts of the original building that can still be seen do not suggest a need for such an expansion due to lack of space. However, the forum benefits if @rick2018, @Mellina, @Solveigh, and @hampshire (or specifically in hanghaus style, @ivenh0 and @sichtbeton82) are no longer so "alone" here.

@matte I only left out 1987 from the list because of the smaller house size, even though their sauna (and for me personally even more so the championship-level kitchen) are dream features 🙂

I have been trying to figure out what bothers me about the floor plan. It is a house designed for a couple, but somehow 1-2 children need to be accommodated as well.

The granny flat or secondary apartment never really gets much natural light. I also don’t think it will be used by children or teenagers. Still, it could work for an au pair or later a caregiver. You have the space and the budget, so why not.
The entrance area downstairs is great.

I would also like to have the bench in the kitchen.
I would give the dining room a bit more space by taking some from the yellow wall. I think it makes the space feel cozier.
The children’s rooms are too small compared to the size of the house. Playing, sleeping, studying, meeting friends, having a place to withdraw to – children’s rooms have many different uses.

The parents’ area upstairs is already quite spacious. I would arrange the bathroom differently. There is a family with children living there, after all.
When they need to use the toilet, they have to go through the parents’ bedroom; if they have stomach problems, they have to pass through the bedroom at night. It’s enough if just one person is awake.

I believe the time when “children need closeness to their parents” is longer than the time when “I want my peace and quiet.” In the end, they turn 18 and have to move out for their education.

I just noticed: the room on the upper floor, which one child is “allowed” to use, is actually a guest/office room. On the one hand, it’s larger than the children’s rooms; on the other hand, where would a guest go to the bathroom at night? Well, they could go downstairs. But overnight guests would have to pass the guest toilet first in order to use the shower bathroom.
I’m sure there are better solutions. Looking forward to another design 🙂

The eave heights are fixed requirements and significantly limit the attic space, which is why the children's area in the attic was discarded.

I have the impression that the upper floor might be sufficient for the two kids plus the children's bathroom. I would move the master bedroom downstairs and the guest toilet could be combined with the bathroom.

Are there any elevations available so we can better visualize the attic?
