Hello,
I'm looking for some answers. We are at the starting point of expanding our house from 1916; the extension will be in a part of our existing barn. The whole house consists of a well-functioning crawl space in the extension where posts stand on existing stone blocks of Älvdalskvartsit directly on the ground, unsure how deep. We plan to keep these stones as they are around the whole house and then dig down about 80 cm and then cast the crawl space.
First of all, I've been looking for so-called "kattugglor" (I think they're called that), which are used for ventilating the crawl space. They are in cast iron; where can you find such things, and what are they really called?
Also, we've been pondering how to proceed, but the old facade should be removed on the extension, and the frame needs to be replaced here and there. Right now, half of the extension has flooring (the old carpenter's workshop), and the part that was the wood shed has an earth floor... (the old floor will become the foundation, unless we come up with a better idea).
But due to winter's arrival, it's impossible to cast and dig now, so it'll have to wait until spring. The question is:
Can I build the frame without casting the crawl space?
(I have a horizontal beam lying on the stone blocks supporting the frame)
Do I have to remove the facade to build the frame? (Thinking that I need some weather protection)
If I have these horizontal beams, could I use them to prepare the floor and then cast the footings for the floor in the spring? Or will that be very cumbersome?
I'm trying to find something to do in the extension now during winter since I'm on parental leave and have a little one who likes to sleep a lot
Hope someone can help a crazy one...
