Construction project. With whom do I build my house in Tuscan style?

Dear builders

I intend to build a house in Tuscan style because I think practical, square, good, is cheaper than if I build gables and dormers.

The plot is available, the building window is 23 x 12

I want to build on the ground floor - 1 apartment for myself with about 120 sqm, and a living, dining room, kitchen and guest WC for the tenant, on the 1st floor - 1 guest room with shower for me and 3 bedrooms 1 bathroom and 1 shower bath for my tenant.
But everything should be separated so that the tenant and I have completely separate areas, I have also possibly thought about building the area on the ground floor for my tenant as an extension or around the corner, because the 1st floor does not have to be as big as the ground floor.
A basement would be good but depends on the price.
Does anyone have an idea what this could cost or an idea how I could design it.
I am also considering whether to build with a property developer or a general contractor (where is the decisive difference?) or whether an architect is ultimately cheaper?

Grateful for any idea is
Evelyn

Since the costs depend on so many factors, I would say just go to different companies and get quotes. It’s not easy to say anything flat-rate online. Location, finished basement, white bathtub [Weisse Wanne], building ground, type of construction, energy standard, heating system, equipment, and so on.

We are building with a general contractor and have been doing quite well with that so far.

I am not an expert, but I believe when you buy from a developer, you usually buy the land and the house and then pay correspondingly more property transfer tax. In other words, the builder is the developer and then sells you the house.
A general contractor builds a house for you and takes care of all the work with the trades (if desired).

Just get various offers and then you’ll have a clearer picture. You can already look up some floor plans on the internet in advance so you have a direction. Based on what you’re saying, I would google semi-detached houses, single-family houses with granny flats, and two-family houses.

Thank you very much,

yes, I already suspected something like that with the developer.
I have already contacted 2 general contractors and am waiting for the offers, I will probably fall off my chair,
since I am building in Hamburg the plot (855 sqm) is already very expensive.
A construction supervisor advised me to take a construction company from my area (North Sea) because they are better and more affordable than Hamburg companies.

Thanks again for your message

We have a construction company from East Germany. They are also cheaper than our local ones, so even the travel and accommodation costs are worth it.

Since the costs depend on so many factors, I would say just go to different companies and ask for quotes. Saying something flat-rate online is not exactly easy. Location, finished basement, white tank, building ground, type of construction, energy standard, heating system, equipment, and so on and so forth.

How is a company supposed to give a serious offer if the information is so vague? A serious contractor will first query all requirements and then create an individually suitable floor plan. Since this involves a lot of effort, it already costs money with some companies. Alternatively, you can also commission an architect to create a suitable floor plan and then go to the construction companies with these in order to obtain comparable quotes. The decision for a construction company should not only be the price in the bottom right, which may be cheaper due to the location in East Germany, but because the company offers the right quality and reliability at an acceptable price. This can, but does not have to be, a company from far away.

Hello Evelyn,

Does anyone have an idea what that could cost or an idea how I could design it.

No, not as long as there is no draft. You will get this via architect, general contractor/GC or also BT.

I am also still considering whether to build with a developer or general contractor (what is the decisive difference?) or whether an architect is ultimately cheaper?

There are countless posts on this topic on the HBF; try the search function and you will have plenty to read.

yes I already thought something like that with the developer. I have already approached 2 general contractors and am waiting for the offers, will probably fall off my chair, since I am building in Hamburg the plot (855 sqm) is already very expensive.

You can fall off your chair if the offers are really overpriced. But just wait.

A construction supervisor advised me to take a construction company from my region (North Sea) they are better and cheaper than Hamburg companies.

I don't want to claim that they are "better"; maybe cheaper; whereby the north of the country is generally cheaper in terms of construction costs. However, it then depends not only on the respective construction company but also on the fine print concerning the assumption of overnight and catering costs.

I am not a fan of a construction partner that is too far away; it can work well, but it can also go badly wrong. The question of warranty should also be included in the considerations.
