Hello everyone,

we are planning to build a semi-detached house with 2.5 stories plus a basement. We have received a first draft from the general contractor and would like to discuss it with you.

The floors are divided as follows:
Basement = utility cellar
Ground floor = living/dining + kitchen + WC + storage
Upper floor = 2 large children's rooms + family bathroom
Attic = bedroom + office + WC/bathroom

Development plan/restrictions
Plot size: 420 sqm (4521 sq ft)
Slope: no
Site coverage ratio: 0.4
Floor area ratio: not specified
Parking spaces: carport + 1 parking space
Number of floors: 2.5
Roof type: gable roof, 35 degrees
Style: semi-detached house
Orientation: southeast
Maximum heights/limits: ridge height = 6.5 m (21 ft 4 in), overall height = 10 m (32 ft 10 in), max width = 9 m (29 ft 6 in). Due to the overall height limit and the 35-degree roof pitch, the max depth = 10 m (32 ft 10 in).

Homeowners’ requirements
Style, roof type, building type
Utility basement, 2.5 stories
Number of occupants: 2 adults + 2 children (5 and 7 years old)
Guests per year: negligible
Large kitchen, open but can be closed off with sliding doors; kitchen island for prep work (cooktop not planned on island for now)
Number of dining seats: 6
Fireplace: ethanol fireplace integrated into the living room wall
Carport
Separate floor for the children with large bedrooms
Sauna in the attic
Dormer on the north side
Ceiling height on ground and upper floors: 2.50 m (8 ft 2 in) each
Office/guest room in the attic

House design
Design by: general contractor (redrawn by me in Sweet Home 3D with furniture added)
What do we like most and why?: large living room with big windows, spacious kitchen, large children’s rooms
Preferred heating system: air-source heat pump

What is the main/basic question about the floor plan in 130 characters?
- Living room: are the windows chosen too large?
- Children’s rooms: how do you find the layout, especially child 2’s room?
- Family bathroom: is the passage to the toilet and shower too narrow?
- Office: 2 m (6 ft 7 in) depth is reached quickly after the entrance; the dormer exists but I’m unsure how the room will feel. What do you think?

I’m not sure if I am allowed to publish the general contractor’s documents online, so I imported the floor plan as a template into Sweet Home 3D and redrew it. It’s a pretty cool feature of the program—there’s not much room for errors.

This so-called "improper use" could fill volumes. I’m sharing this advice here free of charge during my coffee breaks or when, instead of my favorite show, there is a special news report about Karl Ranseier’s death, and professional drawings are often much quicker for me to understand. By the way, copyright concerns are not resolved by showing “just a copy” of a plan.

Thank you for the detailed explanation.
I don't want to unnecessarily prolong the thread, so I would like to stop the discussion about tracing here and focus on the main topic.

The carport is 4.52m wide, and a car is about 1.80m wide. That leaves more than 2m for passage. That should be enough, or am I missing something?
That's right, the single carport is a bit wider than others. But your calculation isn’t quite accurate:
- 5.52m is the exterior width; from that, you need to subtract the roof overhang and posts. You lose at least 30cm (12 inches) per side. (By the way, how is it planned on the house side? With posts or as an attached carport?)
- 1.80m (5 feet 11 inches) is a reasonable width for a family car without mirrors. With mirrors, add about 25cm (10 inches).
- You probably won’t park right at the edge; you’ll want enough space to comfortably get out. Also, you won’t want to drive your mirrors right next to the posts.

All in all, the passage should indeed be sufficient, but you’re certainly far from the imaginary 2.5m (8 feet 2 inches). You’ll need to check exact dimensions for your carport and your vehicle.

That's true, the single carport is a bit wider than others. But your calculation isn't entirely accurate:
- 5.52m (18 ft 1 in) is the external width; you need to subtract the roof overhang and posts. That reduces the width by at least 30cm (12 inches) on each side. (How is it planned on the house side? With posts or as an attached carport?)
- 1.80m (5 ft 11 in) is a reasonable width for a family car without mirrors. With mirrors, add about 25cm (10 inches) more.
- You probably won't park exactly at the edge since you want to get out comfortably. Also, you won't drive past the posts with the mirrors just a few millimeters away.

All things considered, the clearance should actually be sufficient, but you're definitely far from the hypothetical 2.5m (8 ft 2 in). You'll need to check the exact dimensions for your carport and vehicle yourself.

The car is 1.77m (5 ft 10 in) wide without mirrors, a normal station wagon. It will be an attached carport. The width should be sufficient under the given circumstances 🙂. But you're right, it's not completely ideal.

For example, problems can arise if one of you builds without a basement.

The neighbor is also building with a basement and with a shared general contractor. At least, that is the current situation.
