House Design
Designer: planner from a construction company
What do you especially like? Why? Mostly drawn according to our wishes
What don’t you like? Why? Dining area too narrow between kitchen and living room (the left kitchen unit must be this long (from left to right: raised dishwasher, oven and microwave stacked, door to pantry, side-by-side refrigerator, tall cabinet). On the right side, we are considering shortening it a bit to gain more space in the dining area.
Estimated cost according to architect/planner: €400,000
Personal budget limit for the house including fittings: €410,000
Preferred heating system: air-to-water heat pump with underfloor heating

If you have to give up something, which details/expansions
- can you give up: open
- can’t you give up: open

Why is the design as it is now?
We spent a long time drawing, changing, and adapting ourselves. This is the result of collaboration between the planner and our wishes.
Which wishes were implemented by the architect? All

Information:
The house will be a single-family home built in solid construction, KFW55 standard, with photovoltaic system, underfloor heating, air-to-water heat pump, gable roof with a 22° pitch. The family planning is complete with 2 adults and 1 toddler. The house is built on a sloped hillside plot with a 10% gradient, accessed from the street. The basement parts fully covered by earth are made of waterproof concrete, the rest is masonry. The south side faces the street and thus has the main terrace. The passage between kitchen and pantry is hidden behind a concealed door in the kitchen wall unit. From the entrance area to the pantry, access is either via a sliding door or a regular door opening towards the pantry. A lifting system for the lower bathroom is not required since the slope from bathroom to sewer will be 2.8%. The sewer connection on our property is located at a depth of 3.39 meters (11 ft). The house will also be built slightly higher than the street level. A backflow valve is, of course, planned. From the lower bathroom, there is another door leading into the rear garden (north/east). Instead of a deeper foundation due to the slope, the double garage (prefabricated garage) will have a transverse utility garage with a side door, 3 x 7 m (10 x 23 ft), so it can be used as storage / cellar / garden equipment space. The terrace will not extend as much around the corner as in the plan, allowing the ground to slope down more quickly there.

After so much planning, thinking, and revising, it is easy to become blind to details and overlook some things. Therefore, we appreciate any criticism, tips, tricks, and suggestions

Fire away & thank you very much in advance.

If I calculate correctly, your design is over 160 sqm (1722 sq ft).


Is that just for the house, or including all additional costs such as the slope?

Yes, the 160 sqm (1722 sq ft) is correct and intended as it stands now.
That is only for the house itself; additional costs for the house, garage, and outdoor area will be added separately.

I prefer an honest attitude a thousand times over fake smiles, sugarcoating, and then making a face behind someone’s back. I can handle that kind of approach well.

I read your response more as if you were upset about a purely verbal analysis “without” a SoGehteSrichtig drawing.

Our “problem” is simply that we cannot afford a special, custom-designed, or unique house beyond the “standard,” as that would cost a lot of extra money.

There are many independent architects who, even while charging below typical rates, can be more creative when it comes to developing grips than the general contractor’s application drafter. The standard design here is already so heavily modified that it requires a custom structural analysis, and so forth. It would be more efficient to start fresh with a new design. That’s what I actually hoped to make clear: that this Pyrrhic division hasn’t even won here yet, especially considering the cost-effectiveness of finding solutions.

There are also general contractors who can work individually without model homes and glossy brochures.

Has the structural engineering been completed and taken into account? A buffer of 10,000 euros for additional construction costs is very little, especially if the house is on a hillside location.

Since the basement will actually be used 99% by us only, we wanted to avoid a "corridor" just to have an extra door. It was more important to us that our son has a very large room available.

Well, I think that’s a mistake. Maybe you’ll often think of me when you’re lying in the bathtub or sitting on the toilet and someone walks through the bathroom because it’s the direct way to the garden.

Hello everyone, it took us a few days, but we have made some changes. We have now added a door leading to the children’s room, but the bathroom door will remain as it is. You can walk around the house on both the left and right sides.

The exterior planning is not yet fully finalized, so it is not 100% like the sketch. The house will extend 10 meters (33 feet) into the plot, and the garage will extend 7 meters (23 feet) into the plot.

We do not want to follow the suggestion of adding a shower on the ground floor and placing the guest toilet next to the guest room, as we would lose too much space in the utility room due to the new location of the staircase.

We are still waiting for the revised plans, so I cannot upload anything better at the moment.

What do you think about gable windows? The attic is not planned to be converted into living space, so it will be used exclusively for storage.
