ᐅ Initial Floor Plan Draft: Open-Plan Kitchen and Living Area – Discussion and Feedback

Hello,

I would like to hear your opinions on an initial draft (sketch) we received yesterday from one of our preferred construction companies.

Plot size: 835m² (8984 sq ft), gable roof with a 35-45° pitch, slightly sloped terrain.

The design features a gable roof with a 35° pitch. The southern side is elongated to allow for as much space as possible for solar panels. We did not want skylights.

We plan to live there as a family of four (currently two) and, due to our jobs, work more or less regularly from home – therefore 2 work rooms + 2 children’s rooms.

We specifically wanted a separate living room and to place the main living area more in the kitchen/dining space. There is a sliding door between the living room and the dining area. Between the hallway and the dining area, there is a (somewhat undefined) glass/door element.

I would appreciate some initial feedback – unfortunately, due to the “sketch nature,” I don’t have exact measurements.

Regards,
Markus

Hello,
I actually like the floor plan.
However, I would change the layout of the guest toilet and the office. As it is now, they would just become two narrow corridors.
Also, I find the utility room very small considering it has three doors and serves as a passageway. Is all the building services equipment supposed to fit in there?
For the house size, I also find the children's rooms rather small in the end. But, of course, that is always a matter of personal taste. We have a similar room layout (though only one office) with 180 m² (1,938 sq ft) and children's rooms of 18 m² (194 sq ft).
Also, consider whether you really need both offices. As long as you don’t have children yet, you can use one of the children's rooms as an office. If you have two children, will you really be working in both offices at the same time, or would one slightly larger office suffice? At some point, the children will leave the house, and you can use a room again as a children's room. Otherwise, these rooms will just end up as storage rooms anyway 🙂

The second option is a straightforward brick-by-brick build, priced at around 360,000 EUR (all inclusive).

I wasn’t far off; that’s why I think 360,000 EUR won’t be enough.

Single-family house, KfW 70 including building permit / planning permission: 283,500 EUR
Detached garage: 12,000 EUR

Estimated total: 295,500 EUR; according to the cost estimate, 64,500 EUR remain. This amount has to cover painting and flooring, landscaping, reserves for extras, as well as typical ancillary construction costs of 40,000 EUR. I don’t really see that working out; sorry.

That’s quite a significant amount 🙁

According to the architects, the stated costs are based on projects they completed in the area, so I assumed they would be accurate.

Especially since the garage was already included at 17,500 EUR (about 18,700 USD) and the landscaping at 15,000 EUR (about 16,000 USD).

Does your total also include the planning services and structural engineering (architect)?

Hello Markus,

I find that hard to believe since the Ruhr area is not significantly cheaper than Düsseldorf or Cologne. Given the size of the property, I estimated a base cost of only €1,500.00/sqm (around $160/sqft), even though the design will require additional expenses—such as the extra floor height and the concrete staircase, which will still need a finish and a railing.

How is the standard defined? I ask because I was quite surprised recently to read that a well-known Rhineland supplier cut costs on the roof covering construction of the shed roof.

For a masonry garage, that price is too low; for a prefabricated garage, it is set too high.

and the outdoor areas at 15,000 EUR were already included.
For outdoor areas (driveway, terrace, and flat land), I usually budget €10,000 (around $11,000) in the cost estimate, but upward adjustments are always possible. Some landscaping will likely be necessary as well; in the end, that usually leads to an unpleasantly high figure. Just ask the users here 😉

They are always included in my cost estimates.

I don’t have the calculation with me right now, but the standard is not defined.
This is the initial draft based on a discussion with the architect. The “standard” would be defined here in a separate tender process after (numerous) further discussions. The more detailed the planning becomes, the clearer the final price will be 🙂
