I would rather recommend that you first go to an architect and create a proper floor plan. The architect then uses that to prepare a tender, and the companies make offers based on your requirements. This is a bit difficult, of course, if you are absolutely set on a large prefab house manufacturer, because they don’t necessarily participate. Carpenters and smaller prefab house providers are more likely to do so. And in solid construction, this is standard anyway. Maybe you could briefly explain again why it has to be a prefab house?
Masa? Or Massa Haus? Massa Haus is a shell construction company and can be found in the entry-level price segment.
Massa Haus, of course. Yes, that was a shell construction. But basically, that describes our problem quite well – you get 2 (I don’t want to call them offers) price indications that are completely different and vary greatly in scope. Many parts are then packed into some kind of "packages" that make it incredibly difficult to compare the pricing in any way.
We would do floors/walls painting ourselves (we have already done that ourselves or have people in the family who can do it) – but we would hand over more complex tasks.
We prefer prefab houses mainly because neither of us is a professional and we expect a bit more controllability with a quasi-standard product (and also hope for simpler assistance during acceptance by an expert or similar – who might also know the weaknesses of the individual providers). If we hand it over to a general contractor now, we have the same problem all over again, just on a different level.
We don’t have a plot yet but have already started to get familiar with 1 or 2 new development areas.
Hiring an architect and tackling the whole project with them (whether prefab or custom designed) would be a solution; still, we want to build up knowledge ourselves first. We are definitely still far from starting – the only thing we have so far is a financing framework, plus now we are actively increasing "more" reserves to build up equity (i.e., our goal would be to increase the available equity by another 10% within the year).
In addition, we are actively working on floor plans and already have various sketches of how we want the room layout (as an example, the often shown "bathroom with 2 doors" (towards the master bedroom and towards the hallway) is, for example, terrible in our opinion. But all in all, that’s just Sims+.
