Additions to existing buildings?

Father inlaw wants to put a small addition on to the cabin we have, so we can store boots, coats, etc in it. Problem is he believes he doesn't need to connect the room to the cabin. He can just build it beside the cabin maybe an inch or so from the cabin to avoid needing to fully connect the room to the cabin and roof line.

My argument is that it needs to be connected to avoid leaks and future problems.

Some insight in to the pros and cons of additions attached or not attached would be much appreciated.

Thank you.

I'm an architect and own a contraction company.

Yes it is advisable to fully add three walls to form an addition on any existing structure. This will save you money (don't have to build a wall beside a wall), save you space (one wall thickness instead of two) and will ensure that you don't create a gap for moisture, heat loss, and God forbid, rodents, or insects to live.

The roof of the new addition can be under the eave of the existing roof if height allows, or it could be made into a dormer off of the existing roof by creating a peak perpendicular to the main roof.

Hope you find this helpful. Good Luck!

I agree with Suzanne. In addition, your father in-law would probably want heat and electricity and, maybe some plumbing. If it is a separate building (as it sounds as if it would be) then more issues come into play.

A second concern is the point of permits. I know some structures are created without going through proper channels, however this creates all sorts of problems, especially should the property ever be put up for sale.

An addition is an addition and has certain rules to follow (to meet safety codes). Bottom line is to do it properly and reap the rewards of having one larger structure. It will be worth the investment whenever it goes for sale or just for the shear pleasure.
