Dear forum members,

We have completed a preliminary design for our house together with a company and are now at the beginning of the detailed planning stage. Therefore, we would greatly appreciate any suggestions for improvement, critical feedback, and additional ideas or tips regarding the floor plan.

Unfortunately, we do not yet have a site plan, but we do have the floor plans for the ground floor and upper floor at a scale of 1:100, as well as drawings of the house.

Thanks in advance!

Development Plan / Restrictions
Plot size: 700 sqm (7,534 sq ft)
Development according to §34 of the Building Code; the neighborhood features a wide variety of house types, sizes, number of floors, roof styles, etc. A positive preliminary building inquiry exists for a two-story townhouse up to 200 sqm (2,153 sq ft).

Client Requirements
Style, roof type, building type: shallow pitched gable roof, townhouse
Basement, floors: no basement, 2 floors
Number of occupants, age: 2 adults, 1 child (1 year old), possibly a second child planned
Space requirements for ground floor and upper floor: 150 sqm (1,615 sq ft)
Office: family use or home office? Home office for both adults about 3 days per week on average
Occasional overnight guests per year: parents-in-law visit several times a year
Open or closed architecture: open
Conservative or modern construction: modern

Utility garden, greenhouse: possibly
Additional wishes / special features / daily routine, also reasons why something should or should not be included:
- Larger guest room on the ground floor with space for a double bed as the parents-in-law visit frequently
- Guest room on ground floor must also be usable as an office
- Bright rooms / mezzanine
- Open entrance area with open rooms and a view of the garden (a clear sightline)
- Straight concrete staircase to upper floor for dogs and parking space underneath (built-in cupboards)
- Office on upper floor should also serve as a utility/laundry room
- Façade in stone gray with wood cladding elements

House Design
Designer: planner from a construction company
What is liked most? Why?
- Very practical room layout and good room sizes
- Barrier-free access to the guest shower on the ground floor
- Additional storage space in the roof as a storage binder
- Lots of light through large windows
- Laundry room on upper floor close to the bedrooms/children’s rooms

What is disliked? Why?
- Kitchen might be too small / cramped
- Question whether a passage to the kitchen is necessary
- Main entrance is not barrier-free (terrace exit also not)
- The gray elements in the façade are to be replaced by wood cladding to give the house a more distinctive exterior appearance.

Preferred heating system: heat pump

If you had to do without, which details/features?
- Can do without: second washbasin in upper floor bathroom, round window in dressing room (can have a different shape), kitchen island if it doesn’t fit
- Cannot do without: straight concrete staircase, windows, large lift-and-slide door, larger guest room, mezzanine, guest shower on ground floor, walk-in showers, laundry room on upper floor

Why does the design look as it does now? For example,
This is the initial individual draft without adjustments from us so far. A mezzanine, a larger guest room on the ground floor, storage space in the roof, and laundry room on the upper floor were explicitly requested and implemented accordingly.

Floor plan of a single-family home: living/dining, kitchen, hallway, guest room, shower, utility room, terrace.

Floor plan of a residential home: bedroom, dressing room, two children's rooms, office, bathroom, gallery/mezzanine.

North side of a two-story house with central door, vertical windows and round window.

East side of a light gray multi-family house with dark roof, windows and exterior unit.

South side of a house with pitched roof, two upper windows and glass front on the ground floor.

Two-story modern house front with gray façade, dark-framed windows and central double door.

Child 2 and living area feel very narrow and long.

What floor-to-floor height or clear ceiling height are you assuming?

And what tread depth did the staircase you transferred have?


The floor-to-floor height remains unchanged according to the cross-section I shared before. Structural room height is 2.70 m (8 ft 10 in) and the clear ceiling height is about 2.50 m (8 ft 2 in). The staircase used has 6+1+6 steps and measures 1.93 x 2.70 m (6 ft 4 in x 8 ft 10 in).

What are the optimal dimensions for a staircase with a landing given this room height?

I don’t think all the original dimensions are accurate.

For example, beds: if the mattress measures 100 x 200 cm, you should allow 10 cm (4 inches) more in the drawing, at least 110 x 210 cm (43 x 83 inches), better 110 x 220 cm (43 x 87 inches), to account for the bed frame and some space to the wall. This also puts the parents’ bedroom dimensions into perspective. The indicated 304 cm (10 ft) depth is misleading; it’s only 271 cm (9 ft) depth according to the bathroom, so there will be a somewhat narrow passage at the foot of the bed. Maybe there’s also a TV planned on that wall.


As mentioned, the dimensions come from the design software I used. So they should be roughly correct. For example, the bed upstairs measures 180 x 206.5 cm (71 x 81 inches).

In general, the guest area and utility room/WC etc. should be mirrored so that the utility room is more towards the north side near the driveway.


The house is now rotated about 90 degrees in this draft so that the utility room and WC face the street and the entrance is to the north.

We will reconsider the layout of the narrow rooms.

From your point of view, are there aspects in the new design that work well?

Living/dining room, kitchen, and children's room or the whole plot?

Of course, the open-plan area: 3.60 meters (12 feet) is too narrow for a kitchen with only a single row of units. There is hardly any workspace for food preparation. The room feels awkwardly long in a polite way. It is possible to furnish it, but when the dining table is in use, you can’t easily get past the cabinet.
The children's room measuring 2.41 meters (8 feet) is reduced to 2.38 meters (7 feet 10 inches) including plaster. That can be tolerated as a home office, but definitely not as a living space where a child does everything.
I also consider the 2.71 meters (8 feet 11 inches) ceiling height for the guest room, as it is supposed to be furnished, borderline. You can no longer move around the bed or a pull-out sofa comfortably. 2.80 meters (9 feet 2 inches) is my absolute minimum limit; ideally, it should be 3.10 meters (10 feet 2 inches) by 4.10 meters (13 feet 5 inches).

I also find the second custom design quite awful.
An open hallway concept in the living room feels very uncomfortable and is difficult to furnish.
There is little workspace in the kitchen and hardly any storage.
A lot of space is wasted on corridors—for example, in front of the guest toilet, the stairs, and the guest room.
Having two cloakrooms is impractical.
The upper floor has too much corridor space.
Child’s room 2 has a poor layout.
The stairwell is dark.

Why don’t you look at prefabricated house floor plans? Your requirements are really not unusual.

Ah, it would be oriented like this, with north at the top of the plan.

What I notice now is that the stairway would be very dark, as there is no natural light anywhere.

Regarding the stairs… the important factor for design is the floor-to-floor height, not the clear ceiling height, and not the height without finished flooring. So, this would be 285 cm (112 inches).

Cross-section of a house with roof structure, dimensions, and roof pitch 20°.


For stairs, we have added a few typical examples in the pinned thread:

There are plenty of good designs available through search engines.
I would lean more towards this approach. You could move the kitchen to the front and create a small guest room in the lower left corner if such a room is really necessary.

13 steps are at least 2 too few. I don’t know which software you’re using, but stairs should be customizable to fit the house design. I can’t imagine your program calculates this correctly, no offense intended.
