CrixtonHello House Building Forum,
What do you think about the floor plan (see attachment)? This is a first draft, and I am open to any feedback!
Thank you in advance!
Development Plan / Restrictions
Plot size: 390 sqm (approx. 4200 sq ft) with 16.5 m (54 ft) width x 23.5 m (77 ft) depth
Slope: none
Site coverage ratio: 0.4
Floor space index: 0.8
Building envelope, building line and boundary: minimum 3 m (10 ft) setback from the street, linked building in a continuous row. Boundary building allowed.
Edge development: Grouped houses are required: house, garage, house, garage…
Windows: On the ground floor, windows are only allowed on the southwest and northeast sides due to the house grouping. On the upper floor, windows are allowed on the southwest, southeast and northeast sides.
Number of parking spaces: 2 in carport/garage + 2 in front
Number of floors: minimum 2 full stories
Roof shape: hipped roof with max 25° pitch (hence square floor plan)
Orientation: southwest-facing
Maximum heights / limits: max wall height 6.5 m (21 ft). Knee walls not allowed.
Other requirements: A tree must be planted in front and behind the house. This may affect the distance of the house to the street. According to the development plan, minimum 3 m (10 ft) setback is required; I am not sure if this is sufficient for the tree. A free-growing hedge with 3 m (10 ft) depth must be planned behind the house.
Client Requirements
Style, roof shape, building type: city villa with 2 full stories
Basement, floors: no basement planned for now, possibly if really needed
Number of people, age: Currently 2 (male 28, female 25), planning 2 children soon
Space requirements ground floor, upper floor:
Office: several home office days per week, small office (around 9 sqm (97 sq ft)) sufficient
Guests per year: 5
Open or closed architecture
Conservative or modern design
Open kitchen, kitchen island: open kitchen, kitchen island if space permits
Number of dining seats: at least 5
Fireplace: if space and budget allow
Balcony, roof terrace: possibly on top of the garage, but not mandatory
Garage, carport: double garage planned with 6.5 m x 8 m (21 ft x 26 ft). Max length allowed 9 m (30 ft). Only flat roof allowed on garage.
House Design
Who designed it: Do-it-yourself, with some floor plans as templates
Cost estimate according to architect/planner: not yet determined
Personal price limit for house including fixtures: 350k € plus garage and landscaping
Preferred heating technology: If not KfW 40plus standard, connection to district heating is mandatory. If KfW 40plus standard is met, connection is voluntary.
If you have to give up something, on which details/extensions
- can you forgo: straight staircase (if other staircase types are better suited for 10 x 10 m), roof terrace
- cannot forgo: office, guest WC + shower on ground floor, bedroom not directly adjacent to children’s room, pantry, access from garage to house, children’s rooms at least 15 sqm (160 sq ft)
Why did the design turn out this way?
What is the most important/fundamental question about the floor plan in 130 characters?

- cannot forgo: office, guest WC + shower on ground floor, bedroom not directly adjacent to children’s room, pantry, access from garage to house, children’s rooms at least 15 sqm (160 sq ft)
Why did the design turn out this way?
- The maximum width of the house of 10.2 m (33 ft) is based on the plot width of 16.5 m (54 ft). 6.3 m (20 ft) is allocated for the double garage. The house depth is therefore 10 m (33 ft) (hipped roof: square floor plan is advantageous + if deeper than 10 m, the floor space index would be exceeded + hardly any garden space would remain)
- The office on the ground floor could be used as a third children’s room if needed (not currently planned) and later as a care room
- Bedroom is not adjacent to the children’s rooms
- Both children’s rooms have access to the roof terrace on the garage
- Direct access from the garage to the house
- Open living and dining area
- Large children’s rooms (approx. 17 sqm (183 sq ft))
What is the most important/fundamental question about the floor plan in 130 characters?
- Is the straight staircase suitable for a 10 x 10 m layout, or are there better options?
- Is the space sufficient for 4 people, or would you recommend a basement?
- Open to all comments
askforafriend5 Apr 2021 19:18Get some graph paper and draw your plans with real measurements first (forget about the computer for now). For exterior walls, use 40cm (16 inches), and for interior walls, roughly cm. Take a look at what furniture or items you want to include and draw them to scale. For example, a large U-shaped sofa: 3.50m x 2.20m (11.5 ft x 7.2 ft). This way, you’ll quickly see if it fits.
A straight staircase would waste too much space at 10 meters (33 ft); it’s better to choose a U-shaped one.

Do you consider the straight staircase suitable for a 10x10m (33x33 ft) house? Certainly not.

I would prefer other staircase designs. Not just the shape, but also the location. In this row townhouse—middle unit on the ground floor and end unit on the upper floor—the staircase with its narrow side belongs against the neighbor’s wall; in the footprint of a detached villa, it should even be spiral. I see the garage-to-house passage being compromised in this setup.

Suburban villa-
... 🙂OK, I admit this will have more of a "terraced house" character rather than a "villa" 😀
Thanks for the feedback.
I’ve looked at several terraced house floor plans; the ones I found didn’t have square exterior dimensions but were more rectangular (for example 6 x 10m (20 x 33 ft)) and usually 3 stories. That creates a different situation regarding the staircase.
What do you think of the layouts of the Town & Country "Flair 110" (8.5m x 9.13m (28 x 30 ft)) and the "Stadtvilla 145" (9.5m x 9.5m (31 x 31 ft))? Both have a quarter-turn staircase and an almost square footprint. Our floor plan is currently planned at about 10m x 10m (33 x 33 ft), so slightly larger than both.

Definitely not.
Not just the shape, but also the position. In this actual mid-terrace (ground floor) or end-terrace (upper floor) house, the staircase with its narrow side "belongs" against the wall shared with the neighbor; on the footprint of the semi-detached villa it’s even spiral. I see the passage between garage and house suffering because of this.
