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!

No, I mean the developer who built the social housing and the natural gas power plant there and is developing the rest of the area. But after that, we have free choice.

Ok, that’s good then… otherwise, it would have been a tied transaction.

Then it will become significantly more expensive over the next few years... CO2 price, etc...

I would have already walked away when the general contractor hesitated to hand over the plan. And I am uncertain which is the bigger madness: A. believing in a reasonable reduction of the design; B. preferring to give up living space rather than a “random” basement; or C. the hidden pitfall with the heating system. By the way, there is a thread here discussing how this last point breaks an entire housing development (see also: https://www.hausbau-forum.de/threads/auswirkungen-nahwaermeanschluss-zwang.42972/#post-565163).

Well, heating is just the way it is now, and the land has already been purchased. I’d rather pay a surcharge on the heating costs than go through the hassle of trying to resell the land and end up stuck with the expenses. My colleague also seems to be having second thoughts, but sometimes things don’t go exactly as you wish.

Setting costs aside for a moment, is my floor plan realistic, or are there any major mistakes that would make it impractical or problematic? What have we forgotten or overlooked?

I would paint the pantry, reposition the bathroom, and create space for a wardrobe.

You won’t be able to fit a stand-alone freezer cabinet through the pantry door. The interior wall measures just under 130 cm (51 inches). The door opening is planned to be 60 cm (24 inches), and it also needs some clearance from the top wall. With a 60 cm (24 inches) door opening plus the frame, the actual passage will be about 56 cm (22 inches). If the door opening is made wider, the freezer won’t fit along the lower wall.

This awkwardly shaped pantry definitely needs to be reconsidered.

The same applies to the bedroom and dressing area, which is 145 cm (57 inches) wide... the door there won’t be very large either. Is the upper floor a full story?

What are the plans for the garage, parking space, and so on?
