ᐅ Floor Plan Design Single-Family House – Flat Roof – 142 m²

Hello everyone,

after we secured our plot, we spoke to several construction companies. Some only offer the building volume and want to create the floor plan after signing the contract. That feels a bit like “buying a pig in a poke” to us.

One company approached things differently and, after a several-hour discussion, presented a concept that we would like to share and discuss with you here.

Here is first the questionnaire:

Development Plan / Restrictions

Plot: F 1.6
Plot size: 394 m² (14.7 x 26.8 meters), no slope
Building envelope: 8.7 x 12.0 meters (11.7 x 12.0 meters minus 3 meters (10 feet) setback towards the east)
Orientation: Southeast to south
Floor area ratio / site coverage ratio: 0.4 / 0.8
Number of parking spaces: 2
Number of floors: 2 full stories (additional stepped-back floor is allowed)
Roof type: flat roof
Energy standard: at least KFW 55
Energy sources: photovoltaic system and air-to-water heat pump or ground-to-water heat pump


Homeowners’ Requirements

The architectural style, roof shape, and building type are basically set by the development plan and are acceptable to us (otherwise, we would not have applied for the plot).

We (2 adults and 2 elementary school children) plan to build without a basement, with 2 full stories, and a 9-meter (30 feet) garage. Our planned energy source is a ground-to-water heat pump.

We need 1 bedroom, 2 children’s rooms, 1 office (for home office), kitchen, living and dining room, guest toilet (without shower), bathroom (with shower and bathtub), cloakroom as a built-in wardrobe, and of course a utility room. Additionally, storage space is required. We do not expect overnight guests.

We are aiming for a rather modern design with an open kitchen (with a peninsula) and an L-shaped living and dining area (6 dining seats, no fireplace).

Since we do not want a “traditional” entrance canopy, we would prefer a “modern” solution.


House Design

The design comes from a medium-sized general contractor in the region, with its own project draftsmen and an architect.

What we particularly like is that all our requirements have already been fully implemented in the first draft. Even extras like a bench and an interior light well, which we only mentioned in passing, have been included. In our view, the entrance canopy was also well realized, even if it costs a few square meters of living space.

Especially the storage spaces (and the cloakroom) were very well implemented from our point of view. In the first draft, the bathroom was 2.5 m² (27 sqft) smaller, and there was a storage room in front of it. Instead of the fixed storage room, there is now space in the hallway to optionally place a (built-in) closet or remove it later when the children no longer live at home. This redesign also made it possible to add an additional window in the bathroom. Whether this is really necessary is still open.

The kitchen and living/dining area were efficiently designed despite the 42 m² (452 sqft) size.

The guest toilet might be a bit oversized, but worse things exist.

The office window might look better if centered in the room, but the window below it in the kitchen makes this more difficult.

The window in the bedroom behind/above the bed may not be perfect either. We have considered several options and concluded that this is the best solution.

With 16 windows, the house feels like it has quite a lot. We wouldn’t know which one to give up—except maybe the second window in the bathroom. We are also wondering whether the large window in the dining area really needs to be that big.


What is the most important/basic question about the floor plan in 130 characters?

Do you have any suggestions on what we could adjust in the floor plan? Any ideas about the windows (large one in dining, two floor-to-ceiling in bathroom, central in office, behind/above bed in bedroom)? Perhaps we can discuss the kitchen layout here or in a separate thread later.

Urban plan with colored plots (F/E/G), bike path, streets, and compass rose.


Plot plan: red house on green land, parking space and neighborhood square.


Ground floor plan: terrace, dining/living, kitchen, hallway, WC, utility room, garage.


First floor plan: bedroom, office, two children’s rooms, bathroom, and hallway; staircase in center.

The original poster just received the first draft and now the discussion is about wall cabinets?

If the draft has no or very few critical points, it will be built as is. The general contractor obviously isn’t bored and tells the planner to prepare an optional version if everything else fits.
There are things you can tolerate — but there are also things you cannot... and in all the excitement, storage space, whether for suitcases and decorations or in the kitchen that needs to function daily, is in short supply.

For me, the maximum has been achieved here according to the specifications. What I also think is the insufficient storage space. As guckuck2 already mentioned, where are suitcases, possibly sports equipment, various small items, and so on supposed to go?

The kitchen is barely adequate. Cooking alone is possible. With two people...

Here is an alternative, so the original poster doesn't think we're just too lazy to think.

A bit more kitchen space and, in my opinion, a more appealing layout on the upper floor, but with access only through the kitchen. Space under the stairs used as a pantry.
There is now more storage space for cups and pots – but is this actually better? I’m not sure.

I prefer the upper floor.
The desired bench seat is missing downstairs.

Don’t you think it could still fit in the hallway?
I would be much more bothered by the access through the kitchen.

This seemed quite important to the original poster.

If it is now placed in the hallway, access to the open-plan living area becomes very cramped. Coming in through the front door, with the shopping basket passing the bench, where there are again some unattended shoes, then through the rather narrow access to the kitchen.
You are right, the access is tight.
