With BU, costs are constructed based on an example

I earn above average, am married and have 2 children. In 2018, I saved 6000€ every month. Our monthly expenses amount to 4500€ 1600€ warm rent (115m2 near Frankfurt) 800€ health insurance (self-employed) 450€ groceries (obviously we do not save here) 450€ vacation (calculated very generously) 350€ car (an old car is enough, I ride a bike) ... Age 38 years Equity 350k, I would want to invest a maximum of 300k of that. I have saved the equity alone, no inheritances or gifts. So I have been living significantly more frugally than necessary for a long time and I lack nothing. My income is irregular and project-dependent. Constant is 1500€ net from my wife. Since I am self-employed, I have to take care of my own pension. So I cannot put the entire income into the property. Now to the actual question: Ausstattung Of course, the following services are included in our prices: • The offered plot, including any possible demolition and clearing work • Creating the building application, including static, thermal and sound insulation calculations • Energy demand certificate according to the Energy Saving Ordinance • Continuous construction-related quality and deadline controls • Blower door test • Solid stone-on-stone construction with high-quality Poroton insulating bricks • Full basement • Wall and floor coverings • Branded sanitary objects and fittings (German manufacturers) • Wall and floor tiles in bathroom, guest WC, kitchen and hallway on the ground floor • Heat pump with underfloor heating in all living rooms • Plastic windows in multi-chamber system with triple thermal insulation glazing • Interior and exterior window sills made of natural stone • Front door with 5-fold security locking system • Smoke detectors in all bedrooms • The house is move-in ready Lage The plot is located in a dead-end street with 4-5 houses in a very quiet location without car and aircraft noise. It is just 100 m to the field. The school and kindergarten are about 300 m away. With the city bus, you can reach the S- and U-Bahn at the Kurpark Bad Homburg every half hour. Here your children can still play on the street. Many advantages that you are currently searching for in vain. Bad Homburg: Listed at 708,000€ + 57,000€ incidental costs = 765,000€ What would realistically be added to that? I don’t need luxury, but it doesn’t have to be the basic version either. I would like electric roller shutters, LAN cables in all rooms.

Garden and terrace paving etc. 15, connections and drains 8, carport and shed 10, patterns, meaning windows not in white, roller shutters, different toilet bowls or similar, 10 painting work and vinyl floors 15, so almost 60 on top. Then furniture new fitted kitchen, hard to say, 5 or 50, everything is included, lamps also huge range, one buys Ikea, the other only at Leuchten exclusive studio. K.

Heat pump on the property can only be an air blower - you have to want and like it. In the photos from your link, there are probably houses with gas boilers and solar collectors to be seen (why?)

- do they build monolithically? (no additional insulation on the masonry) can cause additional costs, but it depends on the company

- Against unwanted guests, an additional mushroom head lock in the windows helps. Allegedly, no one climbs in through the front doors anymore because the hinges and anti-lift locks are too stable. I cannot give any cost information about this

- Electrical stuff! What the standards require for sockets in the house is by far not enough. Costs are hard to predict because you don’t know what you want. Including switches/sockets, the additional costs in our house amounted to around 8k€

- own construction supervisor (prerequisite is a clarified house right question) 3-5k€*

- despite a network in every room, an antenna connection (a few hundred euros)

- property enclosure (fence)

- wall and floor tiles are included up to which price (surcharges for "special sizes"?)

- chimney including fireplace/stove from 8k€ for something simple

*often, when building with a developer, you do not have house rights during the construction phase, so you can only supervise if the company allows you or if you have contractually stipulated it. 'Building myself with a general contractor, I reached defect number 91 the day before yesterday and would most like to give the company boss a "personal talk." Only the criminal code is still preventing me from doing so. If you forgo your own inspections, the developer can hand you a junk property, and you don’t notice anything because plaster and wallpaper are stuck over it. It all looks so nice and smooth...

I do not see anything about the usual incidental construction costs: site setup, construction road, container, toilet, electricity and water, earthworks, building permit, etc. -> Minimum 25000 Plus exterior facilities such as carport, garage, entrance platform, paving. -> Minimum 20000 Any changes or higher-quality fittings you choose will cost extra. See electrical work, e.g., outdoor lighting and satellite dish, see sanitary installations, e.g., second washbasin, rain shower, lifting system in the basement, the living basement mentioned in the exposé, See tiles, e.g., larger formats, more elegant flooring, etc. Ventilation system is not included.

Hello, you have a great starting point. Basically, you should think about what you want and calmly provide a detailed description.

Example:
[Marken-Sanitärobjekte und –Armaturen] (German manufacturers)

You can get the private label from the wholesaler as a standard that you like or something high-quality that always costs an extra fee.

Wall and floor coverings: laminate? parquet, PVC? painter’s fleece? What about wall painting in, for example, pastel tones?

We also had a construction company, the standard was very good, but often we wanted something different which always had a “reasonable” extra charge. However, it was rural.

My colleague also bought in your area from the construction company, and he felt like he was always complaining when he wanted something different. It always cost an immense extra charge.

The best thing is always to sample as much as possible upfront. Then the construction company has no room for negotiation. Later everything is possible if you pay for it… and possibly get annoyed.

And always get extra charges in writing, also watch out for the net/gross trick.

and additional charges always in writing, also watch out for the net/gross trick

You are absolutely right! Although I really wonder why this is actually the case, when private customers must always be given the final price and no final price with the note "plus VAT" is allowed.
