Apartment for parents: 210 m² single-family house and 80 m² apartment

Hello everyone,

We are planning to build a house with a granny flat for the parents. The main house has 2 full floors and a hip roof, and to reduce costs somewhat, the granny flat and the garage will have a flat roof.

The house is being built in a new development, and I have planned the floor plan. The plot is 924 m² and is number 30 on the plan. Floor area ratio: 0.4 Floor space index: 0.6 TH: 4.5 - 6.5 meters

The driveway can only be on the west side because there will be a bus stop on the south side.

What worries me: The east wall on the upper floor runs right over the living-dining room and actually rests "only" on the wall between the staircase and the storage room of the granny flat. Would this cause problems with the structural engineering?

I have drawn the exterior walls as 45 cm and the interior walls as 15 cm. Load-bearing walls could actually be made at 20-22 cm.

The "wet rooms" like toilets, etc., are distributed throughout the whole house, and the granny flat is also supposed to have its own heating. The wastewater gullies are located in the south of the plot at the boundary to the bus stop.

Hello,

there are problems with the static structure, as you already said: there must be a proper partition wall between the granny flat and the main apartment. Furthermore, the upper floor needs to be supported. This zigzag separation just happened like that???
How is the east wall on the upper floor supposed to run? What about the roof? I think this is nonsense.
For the masons, there will finally be edge allowances for the house if it were buildable

Is there a parking space and a terrace for the granny flat?
The bedroom of the granny flat has a window to the terrace of the main apartment. The bedroom window faces south, the kitchen window to the west. It gets too hot in the bedroom, and the big kitchen is too dark. The living room somehow doesn't exist. There are a couch and armchair, but very unhappily placed without any coziness. No door has a space-saving closet behind it, which means a family closet (or a two-person closet) has no place. Washing machine and dryer stacked in the bathroom? Then they half block the window.
If someone in the granny flat is sick, the other person cannot have visitors because the toilet is at the other end of the apartment.
The all-purpose room is a dark cave

Regarding the main apartment:

Is there heating for the main apartment? I miss it.
I find it unfortunate to have a sauna behind the garage and storage room... Should that be heated area now or outside the thermal envelope?
The storage room will be ice cold, the pipes will freeze... you walk through sand...??? The bathroom there is too tight to get to the sauna.

I like the kitchen, but not the placement of the fridge - you end up walking miles

The door placement errors continue upstairs: I am not talking about the hinge side, the mistake usually lies in incorrect use of the program and can be changed quickly.
The corridor is nice and wide, but the doors... now I found the heating.
The location of the heating is bad for the utility connections.
I don't like the doors at the upper end of the corridor. And here too, south-facing windows are very scarce. The dressing room has no window - I assume because it would disrupt symmetry? A washbasin for five people?
The bump at the entrance and bedroom is also somehow over the top.

Is there a reason why the house is angled away from the sweet spot southwest (besides the street, which will probably only be a residential street)?

For this last reason alone, I would completely redesign everything.

If you like it: many other things, as listed, do not fit and apparently just happened. This is not optimal.

Why don’t you let a professional plan it?

And:

Please read and ...

That is quite a creepy cabinet of little chambers and walls. This collection of (already violated in several places) minimum dimensions completely collapses if you just imagine a piece of furniture slightly moved throughout the entire house.

I advise paper and pencil. It becomes much more apparent while drawing if you create a labyrinth. In color and if dimensions are automatically added, nonsense looks like it could actually work.

und um die kosten etwas zu drücken auf der Einliegerwohnung und der Garage ein Flachdach.

in combination with

Die "Nassräume" Toiletten usw sind auf dem ganzen Haus verteilt,

is practically a summary of a maximally confusing approach.

You are right about everything, most of it has just happened that way.

I have already thought through many arrangements and drawn the layouts, as you can see in the photo below.

Yellow: Garage
Blue: Single-family house
Turquoise: Granny flat

However, I am not yet 100% satisfied with any of the arrangements, because there are also a few things to consider.
- Driveway only from the west side.
- Garage and granny flat should be attached to the house.
- Sunny side
- The main house should rather have the sunny side in the south, SE or SW
- The single-family house is going to be a city villa, if the granny flat is on the side, then something must also be built above it as an upper floor of the single-family house.

The toilet behind the garage is rather intended for the summer, so that you don’t have to walk dirty through the whole house to shower. The sauna will be turned on anyway when needed, then it gets warm there. Where else should it be placed, it should be on the ground floor.

""Is there a reason why the house is not oriented towards the prime spot SW (except for the street, which will probably only be a residential street)""

Do you mean why the house is not standing in the SW? Could be, no reason.

No, why is the house turned away from the SW side? South-facing windows are important! Orientation is important.

Just a spontaneous thought: -> Garage on the north boundary, boundary development. Next to it, entrance to the granny flat, which extends to the rear, living room/terrace facing south/east. Main house in the middle with terrace in the SW...
Is a granny flat even allowed?

I also once considered a garage on the north side, but then you cannot go directly from the garage to the garden of the single-family house, and if, as I understand it, the entrance to the granny flat is then to the right of the garage, you do not have a private passage from the single-family house to the garage because you have to go through the entrance area of the granny flat. Yes, a granny flat is allowed and even 2 semi-detached houses, but only 2 apartments in total.
