Hello,
I have been following this forum for a while, and now we have purchased a plot of land and are planning to build a house on it.
Questionnaire:
Zoning plan / restrictions
Plot size = 525 m2 (5650 sq ft)
Slope – 1 m (3 ft) elevation difference downward towards the south
Site coverage ratio = 0.4
Floor area ratio unknown
Building envelope, building line and boundary = Plot 18.2 x 29 m (60 x 95 ft), building envelope 12.2 x 20 m (40 x 66 ft). Similar plots on the left and right (new development area)
Edge development = No
Number of parking spaces = 2
Number of floors = 2
Roof pitch = 25–45 degrees
Style = Modern, timeless
Orientation = unknown
Maximum heights / limits = Eaves height 4.5 m (15 ft), ridge height 8.5 m (28 ft). Since eaves height is measured from the base reference height, which is 1.5 m (5 ft) above ground level, we can build two full stories.
Homeowner requirements
Style, roof type, building type = Modern, straight and practical. Gable roof oriented east–west (with photovoltaic panels).
Basement, floors = No basement, 2 floors
Number of occupants, age = 2 adults (around 50), 2 teenagers
Space requirements ground floor (GF), upper floor (UF)
Office: family use or home office? = Home office 4 days a week, requires a dedicated room.
Guests per year = Several, family lives far away and often stays for 1–3 weeks at a time.
Open or closed architecture = Open
Conservative or modern design = Modern
Open kitchen, kitchen island = Yes!
Number of dining seats = About 6
Fireplace = Yes, small masonry stove
Music / stereo wall = No, no TV on the ground floor either
Balcony, roof terrace = Yes
Garage, carport = Yes
Utility garden, greenhouse = No, rather flowers and nature, small but nice.
Additional wishes / special features / daily routine, also reasons why something is or isn’t wanted
We enjoy cooking; the kitchen should be the centerpiece. Inside and outside should feel connected. Lots of natural light, no roller shutters.
The ground floor should be accessible and age-appropriate, not just for us but also so that a grandparent could live there someday (then we could use the upper floor). Better to have it and not need it than need it and not have it.
A southern view (fields and forest) is important.
The upper “chill room” should be designed so that a kitchen can be installed later if a child or grandparent wants/needs to live there independently.
We want to build the house from solid wood, though the exact type is not decided yet.
Possibly a polished concrete floor on the ground floor, parquet or similar upstairs. Ground floor ceiling height 2.7 m (9 ft) – is that sufficient? For the ceiling thickness, I have currently planned 40 cm (16 in) using glued solid wood panels (no beams). The upper floor ceiling height can be lower since these rooms are smaller.
Garage is less for a car and more intended as a double carport.
House design
Who designed it:
- Do-it-yourself
What do you like most? Why? Ground floor with easy access to the terrace and garden and a private southern view, covered terrace (usable even in rain). Kitchen near the west terrace with its own access.
What do you dislike? Why? The upper floor feels a bit too large, but this results from the ground floor layout (compromise). Also, I think the staircase doesn’t have enough space.
Cost estimate from architect/planner: We haven’t reached that stage yet, I currently estimate about 2500–3000 Euros/sqm (230–280 USD/sq ft).
Personal price limit for the house including fittings: less than 600K (plot already paid for, terrace and carport I can do myself)
Preferred heating system: Air-source heat pump with underfloor heating
If you have to give up something, what would it be?
- Can give up: Living space, kitchen island
- Cannot give up: Barrier-free accessibility on the ground floor
Why is the design like it is now?
Days of careful planning and adjustments.
What is the most important basic question about the floor plan in 130 characters?
How can we reduce the house size or cost without losing ground floor functionality (barrier-free)? We worry about costs (maybe unnecessarily). Any other cost drivers you see? (Apart from masonry stove and too much glazing). General feedback is welcome.
(I’m not a native speaker, please excuse any spelling mistakes.)
Thanks to all!

I would plan more for the present. pagoni2020 schrieb:
I agree.
I think people still try to anticipate too many future scenarios. However, there are countless others, and then the next thousands will occur. I would plan ahead for the basic, most likely situations; the rest will work itself out. Especially since the budget for such all-in-one construction approaches combined with other wishes often does not add up...
I did some rough sketches, but with the given requirements, there isn’t much room for variation. I prefer the layout with the bathroom and bedroom arranged this way, but the utility room and bathroom become even smaller. A wardrobe might be possible in the stairwell area.
However, the entrance situation is particularly problematic. I agree with the others—reconsider the entire concept.

I don't like enclosed stairwells. Here, there is no enclosed stairwell but rather a "hall" in the literal sense. Acoustic construction will be necessary to prevent noise from the entrance area downstairs from being heard upstairs.

I would open up the stairwell, making the kitchen and dining area the central focus. Interesting idea, I like it. I will try to work on this in the next few days.

Draw in a bed with an interior dimension of 2 meters (6.6 feet) The drawn bed is 2 meters (6.6 feet) wide (external) and 2.3 meters (7.5 feet) long, so it should already fit approximately.

Electricity and water connections can be on the west wall. os24laenger schrieb:
Mechanical ventilation with heat recovery can be installed on the ceiling. The technician and installer need working space. Connections/fittings/meters must be accessible and adjustable with tools.
The electrical cabinet requires a 1.50m (59 inches) clear working area in front of it.

Laundry drying will be done outside; in bad weather, sometimes in the living room or guest room upstairs, or the useless hallway 🙂 Where will laundry be sorted? Folded? Ironing in the living area is fine, but there also needs to be space for temporary storage...

Cleaning cabinet can still be under the stairs. Um… what else should fit into that tiny hallway? I thought I read something about an age of 50... you should know that recycling space takes up room and that people own more than just one jacket.
