Hello,
I am planning to build a single- or two-family house and have an idea of how I might proceed. I would like to hear or read your opinions, as this approach may not be fully developed and might lack many details (e.g., requirements and predefined materials). I would appreciate some support.
Currently, there is a fully serviced plot of land available. I want to build a standard house on it—so no special components and no exceptional thermal insulation, just a maximum energy standard of KfW 70-90. It should be two stories with a full basement (usable cellar) and a gable roof pitched at about 35-45 degrees, possibly with a knee wall depending on the price, since the attic might be converted later. I am looking for a shell construction including roof and basement, without plastering or screeding work. Windows, sanitary installations, heating, and electrical systems would be tendered separately. The house has a footprint of about 125-130 sqm (1345-1400 sq ft) per floor.
What specifications should be made? Building materials? U-value? I was thinking of sending various shell construction companies self-prepared dimensioned floor plans, area calculations, and a volume calculation. Question: What information is needed for a preliminary quote? If the price is acceptable, is it possible to use a structural engineer or architect through the builder?
At the same time, I would also submit my planning to architects or present it in a free initial consultation. What else should I consider or possibly mention when requesting a quote?
PS: Sorry for the spelling mistakes. I wrote this text on an old iPad.

You are aware of the building regulations for two-family/multi-family houses and multi-storey residential buildings, right?Apparently not

Infosauger24 Aug 2018 08:53The plan is essentially for a single-family house with a granny flat. It could potentially become a two-family house in about 30 years, once the children have moved out. I still need to gather information regarding the requirements for a single-family house, so this is an item that should be included in the tender. Thank you! The specifications according to the development plan are quite flexible. Two stories, with no roof restrictions except possibly in relation to neighboring buildings. The plot is fairly large, and the allowed building areas are more than sufficient.

Infosauger24 Aug 2018 09:49Since I want to save money with the bids, I would like to stay under 500,000 EUR. I think with 500,000 EUR I can have everything done, including the basement, at a construction cost of 2,000 EUR per square meter (about 186 USD per square foot) of living space.

No matter who issues the tender, the contractors have their set prices...
montessalet24 Aug 2018 10:20An architect will only create a rough cost estimate once they fully understand your requirements and have a basic plan (initial draft). This rough estimate will not yet include some items (for example, additional construction costs, which can also be significant).
Only after the trades have been tendered and the bids received will they provide you with a binding cost estimate.
And you can probably forget about 2000€/m2 (including the basement). Basements alone usually cost around €50,000 (often even more). But let yourself be surprised........
