Hello everyone,

After reading through the forum for a few weeks, I would now like to ask for your help…

We (my husband and I) have finally acquired a plot of land and now want to build a single-family house. We have been working on it for quite some time. Starting with wishful thinking, we have now arrived at a size and layout that roughly fits our ideas and seems feasible. But now we would like to hear your opinions on the floor plans… Of course, I will also fill out the questionnaire (to the best of my knowledge and as thoroughly as possible ;-) )

The house is currently planned with an exterior dimension of 10x10m (33x33 feet). To the north is the main road leading out of the town, and to the west, there is a traffic-calmed residential street where our driveway is located. To the south, another single-family house will be built, and to the east, there is farmland.

Development plan/restrictions:
  • Plot size: 528 sqm (approx. 5,685 sq ft)
  • Slope: no
  • Site coverage ratio (building area ratio): 0.4
  • Floor area ratio: 0.5
  • Building envelope, building line and boundary: For the house, a setback of 3m (10 feet) is required on all sides; garage may be built up to the property boundary except on the west side (1.5m (5 feet) setback required) and the east side (3m (10 feet) setback required)
  • Edge development: Garage allowed to the south and north
  • Number of parking spaces: 2
  • Number of stories: 2 full stories possible and desired
  • Roof type: no regulations
  • Architectural style: no specifications
  • Orientation: ?
  • Maximum heights/limits: Ridge height 9.5m (31 feet); Wall height 6.50m (21 feet)

Homeowners’ requirements:
  • Style: Preferably a modern urban villa; roof type still open
  • Basement and stories: Full basement with waterproof concrete shell ("white tank") due to groundwater and two full stories
  • Number of occupants: My husband (34 years), me (30 years), child 1 (2 years), child 2 (1 year)
  • Space needs: Living/dining area over 35 sqm (375 sq ft) and an additional guest room/office that could also serve as a third child’s bedroom if needed
  • Office will currently be used only occasionally for home office and as a quiet retreat for focused, undisturbed work
  • Overnight guests per year: Often, since both families live over 300 km (186 miles) away
  • Open floor plan desired
  • Modern construction methods
  • Open kitchen; cooking island not necessarily required
  • Dining seating: We would like a dining table for 8 people, but it must be extendable without needing to rearrange the entire living area
  • No fireplace
  • No music or stereo wall
  • No balcony or roof terrace
  • Garage/carport: Large double garage for bikes and/or shelves for winter tires or similar storage
  • Utility garden/greenhouse: We want to have most of the garden as lawn and possibly a small part as a vegetable garden
  • Laundry chute
  • A utility room large enough to set up an ironing area
  • Planned wall thicknesses: Exterior walls 42.5 cm (17 inches), interior walls 17.5 cm (7 inches)
  • The basement includes the rooms we want but we are unsure about the exact size needed for the mechanical room, etc. The hobby room is also intended to be used as a guest bedroom and music room among other uses.

House design:
  • The house design comes from us. No professional planner has reviewed it yet
  • We like very much that we were able to reduce some areas without noticeably losing living space
  • Unfortunately, the children’s rooms are now somewhat smaller than originally planned due to adding an extra room (originally, 15 sqm (160 sq ft) per room was planned)
  • According to initial rough architect cost estimates, we will pay about $450,000 for 150 sqm (1,615 sq ft)
  • That would actually be our upper budget limit
  • We could probably compromise on the size of the kitchen (a bit smaller would be okay)
  • The living area should not get smaller since at 14 sqm (150 sq ft) it is already not very large; we definitely want to keep the pantry on the ground floor
  • The design evolved from a starting point of about 180 sqm (1,940 sq ft), with an original intention of 160 sqm (1,720 sq ft) until we realized it would be too expensive for us. It was important for us to have the bathroom on the east side and the living/dining area facing south. After that, we did the drawing.

Can we save space anywhere? Especially: In the plan, we currently have a staircase measuring 1.75x2.41m (5.7x7.9 feet). How can we make it wider without losing the quality of the room at the top?

How is the price of 450k broken down? What are the pure construction costs assumed? I mean, 10x10m (33x33 feet) is quite small for the number of rooms you want to fit in, and this immediately shows in the rooms being too small, especially when it comes to bathrooms and bedrooms.

It makes the discussion easier when the plans are shared as images. What can be seen looks quite neat. We will probably still find some minor flaws, but

has already been reflected in the maturity of the design. In reality, the interior walls will not all be 17.5cm (7 inches) thick, especially not around the laundry shaft. The building permit / planning permission area should ideally be clearly visible, as well as the terrain elevation changes on the property.

Why is this (too small) dimension used?

No, appearances are deceiving. The doors shown are 600mm (24 inches) and 800mm (32 inches) wide.
From what I remember from looking at the PDFs earlier, the kid’s bedroom is only about 2.60m (8.5 feet) wide.
The pantry is one meter (3.3 feet) wide. The staircase, at 1.90m (6.2 feet) wide, isn’t even suitable for a townhouse.
The toilets are 600mm (24 inches) and 800mm (32 inches) wide; one is cramped by a wall that is too long.
The walk-in closet is on the sunny side, toilets aren’t stacked vertically (who really cares? These days, pretty much anything is possible).
What’s missing in living space on the ground and upper floors is made up for by too many insignificant rooms in the basement.
The garden on the east side is very small, even though there’s a field? Pasture? Nature? there.

That’s what I still remember from looking earlier today.
Good night 🙂

I don’t find the children’s rooms with 12 and 13 sqm (130 and 140 sq ft) too small. The office will be a bit smaller than the children’s rooms but still usable.
Moving the walk-in closet to the south and making it a dead space is a matter of taste; I would rather swap the bedroom and walk-in closet. That way, you won’t be sleeping next to the shower, and it might be a bit quieter in the morning…

Yes, a request from me as well: please upload the plans first as .jpg files.

Otherwise, from my side, the overall concept basically works, but I also have concerns about the dimensions; if you want to keep the floor plan as it is in principle, I would suggest enlarging it slightly so that the doors have a comfortable width and the toilets are functional.

Does it have to be this exact square floor plan? Are you really set on a townhouse/villa design? A hip roof will also make things somewhat more expensive compared to a simple gable roof...

Definitely swap the walk-in closet and bedroom! Although I’m increasingly less enthusiastic about bedrooms facing south...
Overall, the upper floor has a functional room layout, but you can tell that there simply isn’t enough space for the rooms you want. A room width of 2.6m (8.5 ft) is not very generous.

What are the chances of having a third child?
If that likelihood is rather low, I would sacrifice some space in the relatively large basement rooms for the home office/guest room and instead reserve more room on the upper floor for children’s bedrooms and a bathroom.
Alternatively, make the bedroom a bit larger and do without the walk-in closet.

A rectangular rather than a square floor plan would offer a bit more flexibility, which is why I asked upfront how attached you are to the townhouse/villa style.

The staircase is way too narrow and small for my taste—more like a ladder than a proper staircase.
