Dear house building community,

After much consideration, I have decided to share our preliminary design here. As a longtime passive reader, I would like to give back to the community with this small contribution and perhaps even inspire some readers with our floor plan.

For context: We have completed the preliminary design phase with the architect and are currently gathering quotes. The house will be a prefabricated home with slightly upscale features (KfW-40 standard, Q3 plaster, ventilation system, motorized blinds, etc.) and will cost around 3000 € per square meter (about 280 per square foot). I appreciate any feedback and look forward to many comments. Feel free to critically question the design. One note: we are satisfied with the planning and do not wish to make any changes.

Let’s get started!

Basic data:

  • Plot: approx. 470 m² (about 5050 sq ft) in a new development area with a slight south-facing slope (1 m (3 feet) over plot length, 0.5 m (1.5 feet) over house width)
  • Neighboring plot to the north: unattractive, vacant three-story building
  • Maximum budget for the construction project excluding land and possibly garden/terrace: 700,000 €

Requirements:
  • 3 children’s bedrooms (each 12–14 m² (130–150 sq ft))
  • Laundry or utility/laundry room
  • Study room with space for double desk and guest bed
  • Shower in guest bathroom
  • Straight-run staircase
  • Living-dining-kitchen area in an L-shape
  • Space for hallway furniture
  • Double garage
  • 2 full stories
  • Built on a slab foundation

I have kept it brief on purpose and do not want to reveal what I like or dislike about the design just yet. Instead, I’m going to relax now and grab some popcorn. If you want to know more, feel free to visit my website (Name + “.de”).

I’m looking forward to your opinions!

@roteweste is your house finished? Would you like to share some photos of the result?

Unfortunately not yet, the blog is named after the username, or you can try the following full-text search phrase:

We probably should have negotiated a shorter construction period in the contract or clarified this point more explicitly in the agreement. Our contract states that we will receive the house as turnkey no later than 11 months after meeting the construction prerequisites.

I will definitely share. The move-in date is probably early next year. At least I can post photos of the shell construction by then.

@roteweste, I saw the 3D rendering of your kitchen and understand that you created it yourself. May I ask which software you used for it?

Best regards

Oh, I’ve tried quite a few things already. I hope I’m not breaking any forum rules by mentioning specific tools. I recreated our house using LiveHome3D. You can, for example, download textures from the kitchen manufacturer and then import them there, so you initially get at least a rough but usable framework. In the past, I used that program to render images. They looked somewhat decent (there are still 1 or 2 pictures buried in the thread). Nowadays, I skip that step and take the woodcut-style 3D import and feed it into Google’s AI for image generation ("nanobanana"). I attach the 3D image to the prompt and use the following magic formula, which took me a few hours to perfect:
Role: You are a high-end physics-based rendering engine (like V-Ray or Corona Renderer).
INPUT DATA:

GEOMETRY MESH (Render.png): Use this image ONLY for the positions of walls, arches, and furniture volumes. Keep the proportions 100% accurate.
MATERIAL REFERENCE: Matte textures.
RENDER INSTRUCTIONS (PBR Workflow):

LIGHT PHYSICS (Crucial):
Calculate a complex light distribution. The lamp light must not be flat. It needs realistic falloff (Inverse Square Law).
Produce soft shadows instead of hard edges.
Enable strong ambient occlusion: corners (floor/wall, furniture edges) must be noticeably darker (contact shadows).
Color temperature: Mix warm artificial light (2700K) with cooler ambient light to break the flat tones.
FURNITURE DETAILS (High Poly):
Identify furniture, decor, and pictures; replace them with realistic, matching pieces with comparable proportions and dimensions.
SCENE UPDATE (Japandi style):
Walls: fine plaster. The walls are painted in off-white.
Decor: Replace generic render objects with photorealistic props.
OUTPUT:
A 4k photo in 16:9 format that looks like it’s from an interior design magazine. No CGI artifacts. ISO 400, aperture f/8 for depth of field throughout the room.
That usually produces something quite usable. Of course, I adapted it to the style I want to achieve (Japandi). I can then download the finished image and further modify it with nanobana by typing:
Change the kitchen fronts. Keep the 16:9 format.
Then I attach the original “render” image to the prompt and the new surface.

It all sounds fairly complicated, but I created about 30 images in an hour that way. It only gets time-consuming if you want to add the final touches everywhere.

Maybe an example of what you can end up with.
