Hello dear forum,
after a long back and forth, we have finally decided on a little house.
It will be 175 sqm for a family of five.
Now we are still considering: basement or slab foundation?
We have a slightly sloping plot and are debating what would ultimately be the best option. The basement would only be a utility basement, into which a double garage as well as a workshop and storage room are to be integrated.
The alternative would be building on a slab foundation with a double garage plus a storage option/shed.
Since we are building on a slight slope, the consideration is what costs will come with each option. Of course, no one can calculate earthworks, but maybe someone can estimate.
Two earthworks contractors have already looked at the plot, saying that both basement and slab foundation are easily possible. However, no one wants to give us a rough cost estimate. That makes things difficult.
Our thought was that with the basement construction, which includes two garages, we might possibly save some costs for slope support.
Building on a slab foundation plus a double garage plus higher costs for slope support might end up being in a similar price range.
We wouldn’t have much storage space in the house.
We have the following offers:
Slab foundation 17k + 25k double garage including foundation + sum X for earthworks.
Basement 45k + 20k finishing + sum X for earthworks.
Can/may someone give an assessment of which would be the more sensible option?
