ᐅ Ground floor and basement with bedrooms and bathroom in the basement – what do you think of this layout?

Hello everyone,

We have our first appointment with the architect on Wednesday evening. In the meantime, we have started experimenting with our ideas using Sweet Home 3D and want to bring these to the meeting on Wednesday. What do you think about the room layout and design? The living area is planned to be around 140-150 sqm (1507-1615 sq ft). The listed square meters on the floor plans include both exterior and interior walls according to the program. If I have calculated correctly and subtract the exterior walls and about 15% of the foundation size for the interior walls, you end up with roughly 150 sqm (1615 sq ft) of net living space. The foundation here measures 11 x 13 meters (36 x 43 feet). For now, we are mainly focused on the room arrangement and design. We are building on a slope, which means we will drive straight into the garage, and the property slopes downward along with the house.

Between the vestibule and the pantry, as well as between the vestibule and the hallway, we are considering using internal sliding doors.

We also wanted to ask who has placed their main bathroom with toilet, shower, and bathtub in the basement? Because of the sloped site, wastewater from the toilet, shower, and bathtub would have to be pumped back up to street level. There would be a height difference of about 2.5 meters (8 feet) to overcome. We are wondering if this is possible with a pumping system and, importantly, what the costs might be.

Background: We are building on a slope so that half of the basement can be fully used as living space because it is partially above ground. Since we always wanted a bungalow but need a basement, the option of a ground floor with a livable basement area is the best solution for us. We could also build two full floors on the property, but with a basement (half of which is above ground at the rear), it would look too bulky. The house is intended for two adults and one child, and we are planning to install a photovoltaic system, an air-to-water heat pump, and underfloor heating. The house will be built to KfW 55 standards. The slope means there is a height difference of 3.4 meters (11 feet) over a property length of 32 meters (105 feet).

We are very early in the planning process and are using the software for the first time, so please don’t be too harsh if something seems completely unreasonable or confusing.

Thank you in advance for your ideas and suggestions!!!

The house is larger than 150 sqm (1,615 sq ft).

The living/dining/kitchen area faces the garden. Would swap the floors.
Remove a few corners.

... and please don’t forget the site plan including the slope.

Please do not take the planning documents to the architect. Let the professional surprise you. At a restaurant, you also let the chef do the cooking.

Please don’t bring your own plans to the architect. Let the professional surprise you. At a restaurant, you also let the chef do the cooking.

Well, a lot of nonsense comes out of it as well. When I think of the proposals we have seen, you really have to be careful.

But that’s no reason to take the plans with you. It’s more a reason to change the architect.

No, it isn’t. That’s the other extreme. Even here, where architects, planners, and others should know what they’re doing—since flat roofs are the exception—there’s a lot of nonsense being proposed. Homeowners should definitely know what they want.
