Hi everyone,

We have a plot in the new development area Jahnplatz in Lachen-Speyerdorf and have had initial talks with a general contractor (solid construction). The preliminary plan (we will only receive the official plan after signing 🙄, so I recreated it as best as I could – room sizes and rough dimensions should be correct) matches our wish list but definitely exceeds our budget. According to the general contractor, this is not a problem; we will continue to work together until we reach an agreement. The next meeting is in one month. We have requested two new plans (one with less floor area but still with a basement, one without a basement), including cost estimates. In the meantime, I wanted to ask here in the forum for obvious issues, suggestions for improvements, ideas, and further opinions.

House design
Who created the plan: Planner from a construction company
What do you particularly like? Why? Generally, all our nice-to-haves are covered; we would move in immediately.
What do you not like? Why? Pantry seems to be in the wrong place, cloakroom feels somewhat out of place, garage too long, bathroom and office could be smaller
Estimated price according to architect/planner: 648,000, including extras (garage 46k, ventilation system 16k, solar 10 kWh 22k, lump sum landscaping 25k), excluding earthworks, ancillary costs, and other expenses
Personal price limit for the house including equipment: All in, we have set 600,000 as the budget, meaning we would like to reduce the house price to 500,000 to have enough buffer for everything else (furnishing, additional construction costs, contingency).
Preferred heating system: District heating is mandatory

If you have to give up something, which details/expansions
- can you do without: The garage could become a carport plus tool/bike shed, reading and seating area upstairs can go, bathroom and office could be smaller. Walk-in closet is a nice-to-have and could be arranged differently. If absolutely necessary, we could probably live without the basement, but then the roof must be adapted for storage space and the heating/utility room has to be located somewhere on the ground or upper floor. The pantry as it currently is makes no sense; alternatively, we would enlarge the kitchen and use tall cabinets for storage.
- can you not do without: Shower bathroom on the ground floor, kitchen with 4m length (13ft)

Why did the design turn out like it is now? e.g.
The presented floor plan has been implemented individually and well adapted to the plot with minor exceptions. Some items were only nice-to-haves. The budget has not really been addressed so far. I am a bit worried that the two new variants will also not fit our budget and wonder what else we can optimize.

What is the most important/fundamental question about the floor plan in 130 characters?
How can we best meet our budget? Can we afford the basement, or is that wishful thinking?

Otherwise, I hope I didn’t forget anything in my first post. I have been reading here for a while and hopefully understood the basics 😉 Thanks in advance for your input!

Then it will get massively more expensive in the coming years... CO2 price, etc...

Yes. However, since we still generate electricity from coal, electricity prices will also rise significantly.
And anyone who thinks that tax revenues from oil, gasoline, and gas won’t be compensated through electricity prices... well 😉

Oh man…

I don’t understand how you can just brush that off so easily. You’re fixating on “unlimited space,” and later you’ll be disappointed.

Regarding the floor plan: the walk-in closet will be too narrow for a wardrobe… it’s a simple calculation: effective width measurements of 145cm (57 inches) actually give you about 140cm (55 inches). With a standard 60cm (24 inches) deep wardrobe, that leaves only 80cm (31 inches) to see the clothes inside the closet. At a normal viewing angle of 55 degrees, that’s quite restrictive. Besides, with a standard door width of 90cm (35 inches), you’re left with only 50cm (20 inches) for the wardrobe depth.
The bedroom width of 300cm (118 inches) leaves just 50cm (20 inches) on each side of the bed…

For the ground floor, I would rather suggest this entrance zoning and recommend turning the useless hallway into an open living space.
House floor plan: living room, kitchen, office, entrance, staircase, pantry, WC.

60cm (24 inches) depth is not enough for a wardrobe. In reality, those with doors usually measure 62 or 63cm (24.4 or 24.8 inches) plus the 5 or 6cm (2 or 2.4 inches) you need to leave space from the wall.
With a rough structural dimension of 145cm (57 inches), that leaves only 70cm (28 inches) in front of the wardrobe.
Feels like being in a submarine.

The staircase is missing 3 steps, which is about 81cm (32 inches) in length. Whether it will still work, you should try out yourself.

Yep, it’s all a mess as long as the staircase doesn’t fit.

The software does not count the steps, nor can it calculate them. Based on the dimensions (length), it should fit since it is scaled by length, but unfortunately the staircase width increases as well.
