ᐅ Site planning / floor plan design

Hello everyone,

I more or less stumbled upon a plot of land after someone let their reservation expire.

The plot is about 606 square meters (6,521 square feet), according to my "measurement" approximately 18.10 meters by 33.50 meters (60 feet by 110 feet), not officially surveyed yet, and now I’m wondering exactly what I can do with it.

The development plan sets out the following for "my plot":
  • 0.35 floor area ratio
  • Single-story buildings only
  • Maximum building height 10 meters (33 feet)
  • Eave height max 4.50 meters (15 feet)
  • One driveway with max width of 4 meters (13 feet)
  • Two parking spaces are mandatory
  • Roof pitch between 15° and 51°
  • Roofs of garages etc. may differ in shape
  • Garages, carports, and ancillary buildings as defined by §14 (1) of the building use ordinance, which are buildings, must not exceed the street-side building boundaries of the access roads.
  • Dormers and roof recesses: the total length of dormers or roof recesses per roof side may not exceed 50% of the total length of that roof side.
  • Standard distance to property boundary is 3 meters (10 feet)
  • In the southern area, there is an 8-meter (26 feet) deep strip across the full width of the plot (approx. 18 meters (60 feet)) where trees and shrubs must be preserved. This area is quite densely vegetated and reaches heights up to 10 meters (33 feet) – I’ve tried to visualize this below
  • In the middle of this vegetation is a downward slope... the building boundary to this strip was reduced from the normal 3 meters to 2 meters (7 feet) so the plots aren’t too restricted.

Here I have placed an example house measuring 9.60 meters by 11.95 meters (31.5 feet by 39 feet), which I like based on my initial review (Viebrockhaus Edition 600).

Next to the house, in the 5.50-meter (18 feet) wide space there would be a carport – is that enough space for two parking spots? I would prefer not to make the house narrower just to accommodate vehicles... but then there’s hardly any room left for fencing?!

The terrace and garden at the back are, of course, limited by the tall trees – but that’s a compromise I’ll have to accept.

I’ve never built a house in my life before... so this is my first time dealing with this topic in detail. What would you do in this situation? Make the house a bit smaller?

If you need more information, just ask – as I said, I’m a beginner and eager to learn 🙂

My wishes are:

- Starting from 160 square meters (1,722 square feet) upwards
- I’m currently thinking about a basement and budget around $100k extra for it
- I don’t like long corridors

Once the plot situation is reasonably clear, I’d like to hear your advice on floor plans – that will surely be a more extensive topic.

Best regards

(I would have liked to send you this message via private message, but that was not possible)
This should be in the thread itself, as it was discussed that software is not very good for beginner sketches.

Ok! Thank you very much! And on which page of the 73 posts?
I already looked myself. Unfortunately, I didn’t find anything. That’s why it would be helpful to have the name of the program again briefly. Whether the program is suitable for me, I can then check myself.

Thanks!

Best regards

No idea. It was some time ago... I think it was a CAD program.

Has a car ever been scratched by cardboard boxes on you???
Yes, by the delivery worker’s hand truck 😱 That’s why, when building the house, I made sure no one would have to squeeze past the car.

I actually like the floor plan quite a bit, although without the 2-meter (6.5 feet) line it’s hard to judge whether, for example, the bathroom will work as intended. The bedroom window might also be a bit tight.

Yes, I’ve redrawn the 2-meter (6.5 feet) line and will upload it again later (I’m at the office right now) – the bedroom window fits, but the bathroom probably won’t work as is. It should be solvable given the room size, though. This is just a first draft, which will certainly need and receive some optimization.

What I find a bit unfortunate: The original Viebrockhaus has quite a representative front entrance, but in your case, it wouldn’t face the street—it would face to the side.
...
Your street view is never shown on the Viebrockhaus website, but it can’t be very impressive with windows for technical rooms and the backup kitchen. Also, your street view in the new floor plan doesn’t look very attractive at the moment, I’d guess. I would change the floor plan so you enter the house from the street side and create a nice entrance area there. It just looks better and more inviting, in my opinion. Plus, no one has to walk past cars.

True. However, the representative side comes with a lot of costly upgrades – the standard version looks quite different (no large window front and so on). I’ve also seen such houses from the other side, and it’s true: the street side would look much less impressive… but I’m building this house for myself, not for the neighbors 🙂 My partner would like the entrance to face the street because it would look nicer. I’m not fully convinced yet, as with a house only 9 meters (30 feet) wide, it seems like it would mean a longer hallway inside, which I actually want to avoid. Since I’m financing it alone, I have more say—on the other hand, “Happy wife, happy life” 😀 We will come to an agreement... I have the first exploratory meeting with Viebrockhaus this afternoon… so far, I haven’t heard anything negative about them—even from homeowners in other regions here. Two architects I contacted (asking for a callback) haven’t responded at all yet… but there’s no rush.

Which software did you use to create the drawing of the plot from your first post (Jan 15, 2021)? And would you recommend it?

That’s “SketchUp” – in my opinion, a brilliant tool… I also use it for woodworking projects (desks, etc.) and for 3D printing. Professionals create impressive architectural designs with it as well. It might not be everyone’s favorite here, but I like working with it because it gives me a good feel for things – always keeping in mind that, as an amateur, it can’t be more than a first “idea” and certainly won’t be precise down to the centimeter. I ordered graph paper and such, which I have here, but I’m not very comfortable with it. I’ll give it another chance, though, because I understand the advantages mentioned above.

So, first meeting with Viebrockhaus... it was pleasant, almost 2 hours, some things I already knew, some new information... of course, costs were discussed. What I found very positive was that they didn’t even ask about budget or equity. I had been to Massa Haus before, and their second question was always how much equity I had... I don’t like this "planning backwards" approach. I prefer to know what "my wishes" will cost – I can always downgrade later.

The person yesterday roughly estimated the following:

House according to price list (example house here): 360k
Groundworks: 20-25k (I had provided the general survey of the building area)
Basement including ventilation, underfloor heating, and raising to 2.33 meters (7.64 feet): 120k
Connections: 12k
Material selection: 15k
Electrical selection: 15k
Authorities (building permit / planning permission): 1.5k
Kitchen: 25k
Painter work: 10k
Flooring "upgrades": 10k
Electricity & water costs: 3k
Surveying: I forgot to note that 😉
Garage: 40k (probably cheaper elsewhere?)
Garden landscaping: 30k
Moving: 3k
Miscellaneous: 10k
Total: 680k

Any comments on this? This roughly matches my previous idea... if you then add a 10% buffer, would you say that’s a good path? As I said: I only want a rough idea of what I’m getting into, not to plan "completely wild"... if the buffer needs to be a bit larger in the end, I would increase the equity accordingly rather than take out additional financing.
