Hello everyone,

After successfully finding and purchasing a plot in Schleswig-Holstein a few months ago, we are currently planning our single-family house. On one hand, we are evaluating general contractors for potential collaboration, and on the other hand, we are refining the floor plan.

Originally, a basement was planned (see cross-section), but we cannot avoid a waterproof concrete shell (“white tank”) as recommended by the soil survey for the foundation. Furthermore, the requirements of the energy saving ordinance make basements more expensive. The narrow plot (15m (49 feet)) also complicates slope construction. All these factors have led us to plan without a basement, instead allocating more space above ground.

We’re now fairly satisfied with the preliminary result but aren’t attached to it—at least I hope not... Overall, we planned generously, but I’m still a bit surprised that the ground floor area is about 230 sq m (2,475 sq ft). I’m also somewhat worried that we might have a biased tunnel vision as amateurs, which is why I’m sharing this here.

Please excuse the duplicate floor plans. I find the interior visualization in Sweet Home 3D so poor that I can’t use it for interior design. Hence the separate versions. I hope that’s not too confusing.

At this point, many thanks to the forum; just from reading along, we’ve already learned a lot, which is fantastic!

House design

Who created the design: Do-it-yourself

What do you particularly like? Why?

- Generously sized rooms
- Good separation between master and children’s areas
- Children’s rooms face the private garden
- Master bedroom faces sunrise
- High knee wall on upper floor
- Adequate storage space

What do you dislike? Why?

- Master bath above study
- Storage room on upper floor on south side (but a neighbor is only 6m (20 feet) away here)
- Is the entrance area cramped?

Estimated cost according to architect/planner: 500,000 EUR plus additional construction costs, landscaping, carport

Preferred heating technology: Gas

If you had to do without something, which details/upgrades could you skip: No individual room as such, more a reduction of overall generosity, possibly consolidating the many storage areas (pantry, utility room, HAR, storage closet).

Why did the design turn out this way? Many iterations, balancing wishes, conversations with general contractors, visits to model parks, etc.

What is the most important/fundamental question about the floor plan in 130 characters? Is the floor plan basically reasonable? Have we missed anything crucial due to tunnel vision?

Regarding the building dimensions, I have a tip for a Google search: look for an architect-designed house as inspiration; floor plans are also available as PDFs (plaster/cladding in anthracite would be optional):

** Baumann & Dürr, Residential House in the Muhl, Homburg

Back then, we were inspired by the version

** Residential House Kirchfeld, Karlsruhe Neureut, also by Baumann & Dürr

with its staggered levels, which we then adapted and simplified for ourselves (in the original architects’ design, however, the garage is built with a basement).

Just because something has always been done that way doesn’t automatically mean it’s good

We also tend to stick with it because, so far (although without comparison), we have liked it.

Well, if that helps.

If necessary, we’ll install a steel support behind the sofa. Win-win.

Maybe the vestibule should be shortened a bit, so that the entrance to the kitchen can be positioned further to the left, allowing the living room to be a bit deeper? I find the living room far too short as it is... it almost feels like it blends into the dining area.

Katja, give it a try.

We have a living room measuring roughly 5x5 meters (16x16 feet), and despite having a 2-meter (6.5-foot) screen, we feel the room is too large. We would prefer the sofa to be about half a meter to a meter (1.5 to 3 feet) closer to the screen – my husband agrees. So, a distance of 4 to 4.5 meters (13 to 15 feet) would have been better (rented apartment, what can you do).

It looks like this (the bar is in the left corner).
The sofa has a length of 2.7 meters (9 feet).
