House design
Who created the plan: Planner (architect?) of the general contractor
What do you particularly like and why?

[*]Straight staircase
[*]Covered entrance and terrace
[*]Spacious enough for our needs

What do you not like and why?

[*]WC on the ground floor probably too small
[*]Pantry makes little sense like this (maybe omit)
[*]Layout of the bathroom upstairs (we already have alternative ideas here)
[*]Unsure if there is enough light in the living/dining area
[*]A bit too large/clunky
[*]A bit too expensive

Price estimate according to architect/planner: 565 TEUR
Personal price limit for the house, including equipment: 730 TEUR (including garden, carport, photovoltaics, kitchen, incidental costs)
Preferred heating technology: Heat pump is practically a must (no gas connection)

If you have to do without, which details/fixtures

[*]you can do without: void, pantry, if necessary the type of roofing for entrance and terrace (set back under the upper floor)
[*]you cannot do without: storage space

Why did the design turn out as it is now?
Three-hour appointment with the architect at the general contractor, starting with a similar show house (was a 1.5-storey with gable roof), several iterations on tracing paper, then a week later received the digital design.

Which corresponding wishes were implemented by the architect?: Covered entrance and terrace set back under the upper floor, bedroom with walk-in closet, 2 studies (1 GF, 1 UF).

What makes it particularly good or bad in your eyes? Basically, we like the overall package quite well.

I am looking forward to your opinions and am curious what you think. If we still like the design in January, we will probably push ahead with further planning with the general contractor.

Spacious enough for our needs

A bit too big/clunky

You have to bite the bullet. Although 200 sqm for 4 people is not only "spacious enough," but already wasteful – no offense. But...

A bit too expensive

that follows from that.

Price estimate according to architect/planner: 565 TEUR

Did the planner forget a floor in the price calculation? Or are extensive DIY contributions included? House: 600k + X (pure construction costs for the house, brick cladding is already the most expensive version possible). Additional costs: 50k Carport + storage room: 15-20k Photovoltaics: 15k Front garden/driveway/terrace: 25k (I assume the terrace mentioned in that size is just a placeholder and a real terrace will still be planned – just try placing a garden table for 6 people + grill on 8 sqm... LOL) Garden: with gardener 30k, without according to your wishes in EL. But that is not free either (trees, shrubs, plants, soil preparation, fence, beds, borders, etc.) So your planning with the maximum budget is already very tight, but it could still work if you have no further special requests. Kitchen has nothing to do with the house and the limit.

Did the planner forget a floor in the pricing? Or are significant own contributions included?

In fact, we not only have an estimate, but already an offer with this price on the table, without significant own contributions. We still assume additional services of 20,000 EUR and 20,000 EUR for sampling, but we also hope to negotiate a decent part of that.

Offer for carport: 18,000 EUR
Offer for photovoltaics: 23,000 EUR
Planning driveway/garden: 25,000 EUR
But in fact, so far I have only calculated 30,000 EUR for incidental construction costs.

You have to choose your poison.

You are of course right. I think function will take precedence over form for us, but maybe it can be arranged a bit more elegantly.

Actually, we not only have an estimate but already an offer with this price on the table, without significant own contributions. We are still expecting additional services worth 20,000 EUR and 20,000 EUR for sampling, but we also hope to be able to negotiate a decent amount.

Then please pay very close attention to the service description. As for the rest, I didn't estimate badly. Although the photovoltaic system still offers great potential.

Whereas the photovoltaic system still offers great potential.

The cost driver here is the storage with 12 kWh, maybe a bit large, but we have 11 kWp of power on offer.

Then please pay very close attention to the service description.

I will probably post a few more detailed questions about this in the next few days. How does etiquette look regarding this, is it better to do it here in the thread or open a separate topic?

But for now, I would wait and see what comes up regarding the floor plan.
