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!!!

Then living space fits upstairs. Living belongs to the garden.

The plan is way too large. You have well over 140 sqm (1,507 sq ft). Much more.
We have 11 x 11 m (36 x 36 ft) two floors like you and come to 190 sqm (2,045 sq ft) of living and usable space.

Take a look at city villas of that size. They are 9.5 x 9.5 m (31 x 31 ft).
It may be that you need to be a bit bigger because of the slope, as not all sides have windows.


I thought it would fit if I subtract the exterior and interior walls. We had our conversation today and told him how many square meters of living space we would like. If it's well planned, 130–140 sqm (1,399–1,507 sq ft) would be enough for us. He just said to let him plan it first, so now I’m curious. The waiting is tough.

Would you like to include a window in the (separate) shower room? I find windows in small rooms with a lot of steam especially pleasant. Unless it’s a sauna.

Yes, the idea of adding a small window in the shower room was already on my mind. Maybe the entire bathroom can be planned differently. We will see what the architect comes up with based on our specifications. A sauna was definitely not planned.

I would make sure that the children's room gets plenty of natural light. In the middle of the basement level there is only a side window—how is the slope situated there, and how large can the window be?
Perhaps consider swapping it with the parents’ area. The child lives in the room, does homework there, and needs good lighting, while the parents only use their room for sleeping. Windows on two sides, even if one faces north, will create a brighter, more pleasant living atmosphere. Larger windows might also be possible on the northeast corner due to the slope.

Yes, the point about the children’s room and the bedroom is correct; we also told him today that it is very important to us that the children’s room receives plenty of light. We are really looking forward to his design.

I would say: we’ll meet here again once you have the plans. In the meantime, you can browse the forum and maybe contribute to some discussions others have started.
