House Design
Who created the design:
- Planner from a construction company
- Architect: many inspirations from picture books
- Do-it-yourself: and then supplemented by us according to our needs
What do you particularly like? Why? The open and transparent architecture on the ground floor, the clear southern orientation
What do you not like? Why? Perhaps it is a bit too small, so we might make it one meter longer. We can only fit the home office & guest room in the basement.
Price estimate according to architect/planner: We told the construction company a limit of 500,000 € for the house, and so far there has been no rejection. We do not have any firm offers yet.
Personal price limit for the house, including equipment: 550,000 € + carport + utility connections + etc. → max. 700,000 €
Preferred heating system: pellet stove or heat pump

--> Perhaps a quarter-turn staircase would be better, as it would provide additional space for the music room on the ground floor and allow the play area upstairs to be separated from the staircase by a railing.

--> The basement is still not fully planned.

If you have to give up any details / expansions:
- you can do without: the design is already very simple; if necessary, the guest bathroom in the basement and the kitchen island. An L-shaped kitchen would probably also work.
- you cannot do without: the music room and the WC on the ground floor.

Why has the design turned out the way it is? For example:
Standard design from the planner?
Which wishes from the architect have been implemented? --> The construction company’s planners have difficulty implementing our ideas.
A mix of many examples from various magazines? --> Yes
What do you consider particularly good or bad about it? --> The open architecture on the ground floor and the (almost) equally sized rooms upstairs.

What is the most important / fundamental question about the floor plan in 130 characters?
What is your constructive critical opinion of our design? What would you do differently?

The height indication in point 2.5 is unclear. What is considered the surrounding wall? Which handrail height is meant? The existing one or the final one?

I would start by planning the outdoor area first in order to determine the reference point for the ground floor raw slab height.

Daylight in the basement will then be difficult, unless you integrate light wells into the perimeter wall.

In my opinion, a basement is not an option here anyway due to the lack of budget.

Is there already a quote from the prefab house supplier? Does it include the basement or just the foundation slab?

Good question. I would need to clarify this with the local authority.

We have considered light wells.

We still have some budget buffer (at least as long as interest rates don’t rise sharply) for the basement.

Not yet. The first offers should arrive within the next few days. If necessary, that might give us a good reason to reduce the size of the house.

I don’t understand that *scratches head*

I’m afraid that the costs for the house my wife and I have currently planned according to our wishes will exceed the base budget plus contingency. However, I really can’t estimate by how much. Therefore, I am now waiting for quotes from construction companies in order to know how much we will need to cut back – and perhaps also to receive suggestions from them about the main cost drivers so that we can address these more effectively.
