Hello everyone,

we have purchased one of three plots that were divided from a larger property and still need to be developed. Access is via a private road, and all three owners share the traffic area equally. The plot is very well connected for us, located centrally in Bonn, and is perhaps a bit larger than we actually needed. However, it’s not like there are always free plots available in a similar location.

Because there was a lengthy legal dispute between the seller and the neighbors beforehand, we can only build a partial recessed upper floor to a limited extent. Probably for this reason, the plot was mainly interesting for private buyers. An accessory apartment is not possible, and we don’t want one anyway.

Up until now, the planning was done from scratch without considering costs or practical aspects, at least from our side. The architect apparently enjoys drawing, which is understandable at this stage and has a certain artistic approach. We are generally open to all suggestions and ideas on what could be done differently, especially where costs might be saved easily.

Our next step will be to conclude an architect contract for service phases 1 to 5 plus general contractor / main contractor.

Development plan/restrictions
Plot size: >800sqm (8600 sq ft), no slope, building envelope etc. See plan.
Parking spaces: 1 on traffic area and 1 garage
Number of storeys: Only 1 full storey plus a recessed upper floor
Roof style: Flat roof; architectural style: rather Bauhaus
Orientation: Front of the house faces southwest
Maximum height/limits: 7–8m (23–26 ft)

Owners’ requirements
We basically have no specific style requirements. A flat roof results partly from the recessed upper floor and height restrictions, which probably don’t allow a pitched roof.
We want a basement with excavation and two daylight rooms (this was more the architect’s idea). Currently, there are three of us, possibly four in the future. Early 30s and a baby.
We had planned for just over 100sqm (1076 sq ft) on the ground floor and about 75% of that upstairs. Currently, it’s roughly 230sqm (2475 sq ft) ground floor and upper floor combined plus terraces, etc., and the basement.
Office: occasional use, not very important.
Number of overnight guests per year: unknown, but a guest room is planned
Open kitchen, kitchen island: We definitely want a separate kitchen area and like the suggestion of an extended island
Number of dining seats: 4 in the kitchen, more like 8 in the dining room
Fireplace: Not very important, probably no.
Music/surround sound system: 5.1 system around the TV
Balcony, roof terrace: Terrace is a must, balcony above the kitchen results from the recessed floor
Garage, carport: The garage width of 4.5m (15 ft) is unusual and probably makes it more expensive.

House design by the architect
What do we particularly like? Why? Good use of the sunny side, and otherwise all our wishes have been taken into account.
Upper floor: 3 bedrooms, 2 bathrooms. Master bedroom with en-suite bathroom and walk-in closet.
What don’t we like? Why? I could imagine a nicer staircase, perhaps a longer, more open design. Overall, the hallway feels a bit large.
The upper-floor terrace seems somewhat oversized. We are wondering if the overhang casts too much shade on the ground floor.
Price estimate according to architect/planner: with general contractor and all additional costs >900,000€ (over 900,000 euros)
Personal budget limit for the house, including fittings: rather below that.
Preferred heating technology: no opinion so far

Why does the design look like it does?
For example:
There was an initial meeting with the architect during which our wishes were noted.
Ground floor: separated kitchen, combined living/dining area. Another separate room as office/guest room (and possibly bedroom if needed).
Passage from the garage to the house, possibly as a utility room.
Upper floor: 3 rooms plus 2 bathrooms, including one en-suite.
First draft at the second meeting, and at the third meeting this final design was presented.

A harmless question. Double washbasins in the children’s and parents’ bathrooms or not?
My wife is against it, the architect thinks it would be practical. Opinions?

If you don’t share her reasons with us, should we decide who is right by flipping a coin?
What do you mean by "double sink": a double-wide single basin with two taps?

Their reasoning is that they prefer a large washbasin with a single bowl. In reality, we hardly ever get in each other's way now, so having two basins wouldn’t really be necessary, and it wouldn’t be a big issue even with two children. It would also mean more cleaning. The architect’s reasoning is more or less the opposite.

Two sinks in the kids’ bathroom. They often need to leave the house at the same time and can brush their teeth together. Later on, when that’s no longer possible, at least no one complains about the other’s tubes and containers. Cleaning effort is not a valid argument. It doesn’t really matter that much. That’s an argument against having a kids’ bathroom.

What I find much more practical about a large sink is the width of the basin itself. For example, if you want to rinse your forearms properly, it’s much more comfortable to hold your arm under the faucet than with smaller basins, without dripping all over the countertop with your elbow.

Whether this is relevant for children, I can’t say. We only have one. Still, with a large sink that has two faucets, both can be used at the same time.

And a large sink is definitely easier to clean.

I was just about to say the same: a large basin but two taps!
