ᐅ Building plot secured! What now...?

What are the typical costs for surveying?

That depends on what you or your construction manager need. An all-inclusive package is roughly estimated at 2,500 euros; I believe there is a thread where prices and services are discussed, showing a very wide range (try using the search function). Some services are based on the building value, others on the size and condition of the plot, and some depend on the region.
Individual services roughly estimated:
Site plan for building permit / planning permission 800 euros
Rough staking out (for a basement) 700 euros
Detailed staking out (string lines) 300 euros
Building measurement 800 euros
Some local authorities require an additional base inspection for construction supervision (measuring the finished foundation slab) 300 euros

Who commissions it and when?

You need to coordinate that with your construction manager.

Does it have to go through the land registry office?

No. The building measurement usually ends up there, but you don’t have to worry about that if you hire a publicly certified surveyor.

Hello 11ant,

We already understand that the situation is far from finalized.

However, before involving an architect, I would like to develop a fairly clear idea of the "dream house" myself. That's why I'm trying to learn more here.

The Rosenweg is a public road running down to the property boundary. From there, it's a private road, a parcel in shared use. The road width is at least 3m (10 feet).

The floor plan draft is just a rough concept of how the room layout and house orientation on the plot could look.

The questions I am considering in this context are as follows:

- Due to the slope: should we build with or without a basement?
- Where is the best location for the house on the plot?

And then regarding the house itself:

- Lightweight concrete blocks or aerated concrete (e.g., autoclaved aerated concrete)?
- Building services: what really makes sense? A simple, cost-effective gas boiler or a heat pump with exhaust air heat recovery? Water-bearing fireplace? Photovoltaic and/or solar thermal system? Smart home?

We are not focusing on environmental aspects, nothing against "green" solutions, but rather on the economic feasibility of the project.

Best regards

Unfortunately, your questions don’t have simple yes or no answers.

1. What you want or what your dream house must include.
Start with which rooms you need and then
Visit show homes, walk through every apartment with open eyes, what do you dislike about your current home? For example, your dream XXL sofa doesn’t fit – now is the time to plan.
Study floor plans, draw in your furniture.
Then go to the architect or general contractor (GC).
We want
an open kitchen with a peninsula
the living room must fit a sofa with dimensions xyl
a 5-meter (16 feet) floor-to-ceiling bookshelf must be accommodated
bedroom with or without walk-in closet space for wardrobes
and so on.
All that is important to you, what makes you different from others. The architect doesn’t need to know the exact layout of a 3x2 m (10x7 feet) bathroom with shower here, sink there—that’s his job.

2. The energy standard is also important. For example, my provider would be ruled out because KfW 55 (passive house standard) is an absolute rarity there.

3. Basement
For your case, it’s borderline which is cheaper.
I would really get an offer including all earthworks and disposal work with and without a basement.
This should also include the exterior landscaping.
It’s nice to have no steps to the terrace and from there to the garden, and to be able to keep an eye, ear, and voice contact with small children. Your lifestyle habits play a role here, too.

4. Wall structure
If you don’t have a specific preference, I would choose the construction partner you want to work with and use their standard materials.

5. Building services
For many, controlled mechanical ventilation (CMV) is a must.
You simply always have fresh air without having to open windows. Odors in the toilet and kitchen don’t spread so much, and diapers don’t produce unpleasant smells.
If you want CMV, heat recovery is sensible.
Is gas available on the property?
Photovoltaics, yes or no, that’s your decision.
Smart home—what exactly do you want? How extensive?
You can install a smoke detector with app function or a full KNX system with wind, sun, temperature sensors, room lighting, etc.
This often depends on your budget and personal preferences. Everyone has some smart features nowadays; those with KNX systems probably didn’t need to ponder this—they are tech-savvy and were sure about installing it.

I would plan with a living basement or even a split-level design.
Place the house on the northwest side.
Plan the garage or carport relatively close to the street, even if it’s the nice west side.
The north side behind the house is quite far from the street and the yard costs money.
Where exactly to locate it? I would rely on suggestions from the GC or architect.

MI, floor area ratio 0.4, plot ratio 0.8, no restrictions on the number of floors, maximum building height 11.0 m (36 ft) above finished floor level, base height at the middle of the building 0.5 m (20 in), only pitched roofs with at least 20°

I can’t find anything like that – the community’s citizen information system seems to function like the Darknet :-(

- Pumice or aerated concrete

My mantra is to use the material the builder is most familiar with – in our area that’s often pumice stone. You’ve already been advised about Weton; they are also among my top choices in this region.

As Elefant pointed out correctly in #13, the height difference on the building plot is about 1.5 m (5 ft). For a building without a basement, I think that’s just about acceptable. But personally, I would build with a basement.

Without a basement, according to my rule of thumb, that 1.5 m (5 ft) height difference almost comes at 75% of the cost of building a basement. In my opinion, that almost calls for a split-level design. The first thing I would remove is the connecting door to the garage, so that the floor heights of the house and garage can be independent.

… but unfortunately unusable since, as mentioned, it’s not accurate to scale.

Are you in the wrong municipality? Under the citizen portal, there is a menu item for development plans, which leads to a geographic information system that, once you disable your pop-up blocker, reveals the essential information with a click via PDF documents.

Correct municipality, pop-up blocker disabled, but with limited success. A neighboring development plan could be opened, but that is not useful here.

However, it doesn’t hurt if the original poster attaches the relevant screenshots here themselves.

Yes, unless they want to remain anonymous, which I don’t really believe given the digital traces here, but considering my own footprints online, I want to avoid any conflict with a martial artist rooted in the Cyrillic region.
