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

Only in the case of urban villas is the upper floor constructed with masonry for structural reasons.

In typical 'Anstattvillen' with their beam ceilings, this is not done; masonry is used only together with concrete slabs.

Many general contractors are flexible while maintaining high quality. Don’t believe that the bricklayer automatically builds type xyz perfectly. They don’t really care whether it’s 450 cm (180 inches) or 540 cm (213 inches).
The material is clear and should not be changed.

Yes, of course. Linear changes (especially adding half or a whole meter (39 or 39 inches) along the ridge direction) are no problem and easy to accommodate. However, requests that alter priority or clearance situations at junctions of building components can cause complications. Raising knee walls is also easy, but changing roof pitch is a different matter entirely. You get three wishes from a fairy, and the Bible has ten commandments. If you don’t want clients who give you gray hairs, then you insist on a limited menu with a manageable number of options. With a princess like @Shiny86 (or her male counterpart @StanSch), you don’t make money – or worse, she recommends you to her equally demanding friends after you’ve fulfilled all special requests eight times over and back. For good reason, hybrid general contractors/developers usually only build row houses and semi-detached homes on their developer side, as the clientele is less “special” than with a standalone Tuscan-style Bauhaus.

Only one general contractor offered us a modified model home. All the others were custom designs. The model home fit surprisingly well. However, the consultant/salesperson/commission recipient immediately told us that we should consult an architect and have a custom plan drawn up, and gave us an address.

I sent the floor plan as a "rough idea" to Viebrockhaus, as requested. Let's see what they come up with – I will report back.

I will also talk to other general contractors... but I’m the type who feels more confident knowing that large companies like Viebrockhaus have already built several thousand houses, and so far I’ve heard very little negative feedback. Nevertheless, I will get additional quotes once I have an initial offer.

The idea of using architects is also still on the table, but so far I’ve contacted three: I didn’t feel comfortable with one, and the other two haven’t responded yet (callback request with basic project details). I think it’s completely fine if they don’t have time for me right now (it’s good not to overcommit), or if a callback takes longer, but a short message would be appreciated. Trust needs to be built here as well.

We’ll wait and see. As I said, I’m not in a hurry.

Size actually worries me more. A salesperson who disappears after signing the contract. Commission-driven sales. Having an in-house legal department for contracts and complaints.
Someone once said about the local carpentry company, “They can’t mess up a house. If they go bankrupt, they no longer need to go to football, fire brigade, etc., and better watch out not to get beaten up in the evening.” The small company often works with local tradespeople and can be more flexible with their products and skills.

It would be important for me to visit the selection center in advance. If one exists, your options are limited to what is offered there.
Site manager? Is there a permanent one, and when do they get involved?
Own tradespeople or subcontractors? Are subcontractors permanent, local, or competitively tendered?
