Hello everyone,
We are planning to build a house with a separate apartment for parents.
The main house will have two full stories and a hip roof, and to reduce costs a bit, the separate apartment and the garage will have flat roofs.
The house will be built in a new development, and I have already designed the floor plan.
The plot measures 924 m² (11,470 sq ft) and is numbered 30 on the site plan.
Site coverage ratio: 0.4
Floor area ratio: 0.6
Building height: 4.5 - 6.5 meters (15 - 21 feet)
The driveway can only be on the west side because there will be a bus stop on the south side.
What concerns me:
On the upper floor, the east wall runs right above the living and dining area and is actually only supported by the wall between the stairwell and the storage room of the separate apartment. Could this cause any structural issues?
I have drawn the exterior walls as 45 cm (18 inches) thick and the interior walls as 15 cm (6 inches). Load-bearing walls could probably be reduced to 20-22 cm (8-9 inches).
The “wet rooms” like bathrooms and toilets are spread throughout the house, and the separate apartment will have its own heating system. The sewer drainage gullies are located at the south edge of the plot near the bus stop.

Development Plan
I would still like to try rearranging some rooms tonight, but I need information from the link: @@schustrik please fill out the questionnaire for the main house and the granny flat, including must-haves, nice-to-haves with reasons, and preferences.
Also, please confirm the key dimensions or provide information about building boundaries/setbacks.
Feel free to send info about the building area via private message, but it’s not essential if you upload the development plan details.
Regards, Yvonne

This raises the question: why separate the office and guest room in a family home? Especially if it might later be used as a master bedroom. In that case, it’s better to have a proper room.
Another question ... one or two cars in the garage? One of the plans showed only one car, so where are the parking spaces supposed to be?
Why place the sauna/shower next to the garage? What is the main requirement for the sauna? That both units can use it? That there is access to the garden? Placing the sauna/shower next to the garage sets a location, but does not define the fundamental requirements for the sauna.

There are so many “whys” from my side.
I can’t list them all quickly.
The layouts are too restrictive. For example, why does the sauna have to be behind the utility room?
You’ve basically described your poor design.
Question: Would you want to live in the granny flat if you were in your parents’ place?

schustrik24 Apr 2017 23:41The home office should have its own separate room because I do a lot of photo editing and need a quiet environment. The playroom will mainly be used by our young children, where many toys will be scattered around.
The sauna should have easy access to the outdoors so you can roll in the snow during winter. To avoid dirtying the entire house, it should be located as close as possible to the back exit, which should also have a shower for rinsing off after work or gardening without having to go upstairs. Friends have a similar setup, and it’s quite practical. Currently, the sauna is in the attic, which is not very convenient.
I have described what we have in mind. The rough sketch I made is not great because I am not an experienced planner, and the various corners developed gradually over time. That’s why I am sharing the floor plan here, to get feedback and advice.
Yes, I would also live in the granny flat; there should be a passageway connecting the single-family house, the hallway, and the granny flat.
One car fits in the garage with some extra space on the sides for storing tools. At 5 meters (16 feet) wide, it would be possible to squeeze in two cars if necessary. Otherwise, three cars could be parked in the driveway up to the neighbor’s fence, or one in the garage and two in the driveway, keeping the garage entrance clear.

schustrik24 Apr 2017 23:44I would also be very grateful if you could share your ideas on how you would plan something like this.

The reason I sketched it as a rough draft was that I am not the best planner, and also because all the corners were added gradually.That’s exactly how it appears: as if the corners were basically accumulated over the course of multiple drafts.
A single garage—even if a second car could fit closely alongside a workbench—does not suit the size of this house ensemble.
