Hello everyone,

Originally, we planned a solid construction house with an architect. Due to the uncertain market situation and potential cost increases with individual contracts, we have now decided to go with a prefabricated house provider and are therefore switching to timber frame construction. The floor plan remains largely unchanged, but the new construction method requires some adjustments:

The architect planned two or three steps as well as a concrete slab with a raised edge in the outbuilding. The prefabricated house provider rejects this, arguing that both buildings must be at the same level. Direct contact between the exterior wall and the foundation/reinforced concrete wall would lead to moisture and long-term damage. The height difference is small and is better compensated through the foundation.

However, the section shows a critical height offset. Possible solutions would be:
  • Lowering the house (possibly with disadvantages for drainage, daylight, and appearance),
  • Separating the garage and designing the transition with steps,
  • Or leveling the front height already and building the garage higher (steep driveway)
What do you think: Is lowering problematic? Would a separate structure with a connection be more advisable? Do you have alternative ideas?

Elevations, sections, and floor plans are attached – I look forward to your feedback!

Thanks in advance!

I'm not really someone who works with floor plans.

But how do you come up with the idea that a prefabricated house is cheap? That's a misconception. Just like the lemon butterfly doesn’t fold lemons.

I assume that the focus of the change here will not be on solid construction versus timber frame construction, but rather on architect versus general contractor, so that you have the turnkey certainty instead of uncertain individual contracts.

Apparently, that’s not really what’s needed here either.

What do you mean by that? Can you explain the disadvantages you mentioned?

Maybe the original poster should also be told that you can build solidly with an architect and general contractor as well. Also with a fixed price.

That would definitely be a good option. You should tell them that 😉
