Hello everyone,

I have been in the planning phase for some time now.
I created the floor plan myself based on model homes.
To get a professional opinion, I have already talked to a construction company.
The designer initially drew a plan that I didn’t like. At the next meeting, I showed him my proposal, which he liked quite a bit. We discussed some revisions, and that became the first draft.

I would appreciate any criticism or suggestions and look forward to your opinions.

Development Plan / Restrictions
Plot size: ~1000 m2 (not yet officially measured)
Slope: average incline 7 degrees (approx. 1.5m (5 feet) height over 10m (33 feet) length)
Floor area ratio: 2
Roof style: hip roof
Further restrictions regarding the development plan are unknown

Homeowners’ Requirements
Style, roof type, building type: bungalow with basement and hip roof
Basement, floors: basement + 1 floor
Number of occupants, age: 2 people (29 & 34)
Rooms needed in basement: garage (2 parking spaces), office, entrance area + wardrobe, laundry room (washing machine, toilet, possibly a small shower), utility room & storage
Rooms needed on upper floor: kitchen, living room, dining room, bedroom + walk-in closet, children’s room, office & guest room
Office: family use or home office: both family use + home office (both work from home, so 2 offices needed)
Overnight guests per year: approx. 4 times
Open or enclosed layout: rather enclosed; kitchen open to dining table
Conservative or modern style: rather modern preferred
Open kitchen, cooking island: open kitchen + cooking island
Number of dining seats: a dining table for 8 people should fit
Fireplace: not required
Music/sound system wall: no
Balcony, roof terrace: no
Garage, carport: garage, carport possibly later
Vegetable garden, greenhouse: no
Other wishes/special features/daily routine, including reasons why certain things are wanted or not:
We prefer the entrance in the basement since we travel by car about 90% of the time and therefore don’t need a door upstairs.

In the kitchen, we considered having a window as the backsplash (between the countertop and upper cabinets), as we really liked it in a model home. However, it somewhat disrupts the exterior appearance. We are still undecided whether this added value is worth it.

House Design
Who designed it: DIY
What do you like most? Why? We really liked the somewhat separated living room in a model home because it feels cozy. So, we incorporated it into our plan.
What do you dislike? Why? The arrangement of the windows from the outside
Estimated cost according to designer: For the ground floor: approximately 250,000 for the performance stage (shell + roof and windows), ready for interior finishing, which will be done by ourselves. Electrical, plumbing, and screed will be contracted separately.
Basement: no estimates yet
Personal price limit for the house, including fixtures: 600,000
Preferred heating system: geothermal heat with horizontal collectors

If you have to give up something, which details/extensions
- can you give up: guest room (could possibly be combined with an office)
- can you not give up: 2 offices for home office, with my office preferably being in the basement

Why is the design as it is now? For example
We first included all our wishes in this plan to get initial cost estimates.

Looking forward to your opinions.

Best regards from Austria
Basement floor: office, laundry room, utility, two storage rooms, stairs, garage for two cars

Do you own a plot of land and are not familiar with the zoning plan? Or is there none at all?

To my knowledge, there is no building plan / development plan.

Structurally, this is a challenge. The garage has spans of more than 9 meters (30 feet).

Or do you really need that for these kinds of cars?

In my opinion, the budget will hardly be sufficient. It should be a bit more compact and without an in-house garage.

Is there a site plan with elevation details and a north arrow?

Is there really such a plateau on the hillside side?

What do the surrounding buildings look like?

We are located in a rather rural area. The surrounding buildings all have pitched roofs.

Our plot is 1228. I would like to build approximately where the red frame is shown. The plot still needs to be surveyed and will then be reduced in size. The driveway will be accessed via 1230/1.
North is at the top of the image. Unfortunately, I don't have a plan with elevation details, but I have attached an elevation profile. I hope this helps a bit with orientation.

This plateau does not exist yet. However, I would like to create one here to design a garden.

I will request some quotes. Most likely they will bring me back down to reality, and then compromises will have to be made.

It’s immediately obvious that this is an amateur design. My initial impression was: this was planned by someone for whom it doesn’t matter whether the number refers to “Schilling” or “Dollar.” When model homes are just tossed into the mix, the result ends up even more off in size and therefore in price. Then you add a roof as if from a ladies’ catalog, and the reality check needs to be as gentle as possible. “Professional opinions” from construction companies usually amount to supporting everything the client can afford. And draftsmen are happy to offer counter-proposals to clients—so far, nothing surprising.

This was drawn by the planner, I just adopted it as is. I think he didn’t detail the basement because this is a prefab company and I only requested the ground floor. [...] The roof is only like this in my draft. The planner had drawn a shed roof even though we would prefer a gable roof.

Especially if the basement isn’t part of their scope of work, the “planner” naturally won’t put much effort into it and will only address it as much as necessary. Anyone who ends up with a basement due to a sloped site should make use of it (unless money is no object). For example, I also find the second office suitable to be located in this basement, which—thanks to the basement—does not need to skimp on terrace area. I would probably specify a gable roof or a staggered shed roof here, which—ideally designed like a pergola—also covers the terrace. What I don’t understand at all is why only the garden-side view is used here and not the valley view. Have I missed a north arrow somewhere?

Thanks for the excerpts from the plans.

Does the terrain slope towards the northwest?

Is it mandatory in Austria to integrate the garage into the house?

We recently had someone from Austria who mentioned the same thing.

Here is a rough compilation.

Just saying, your parents somehow built better with the slope. In my opinion, you should do the same. @11ant North is at the top.
