I started building a shed last year to use as a home office. The exterior is done and complete, and the interior is maybe 80% done.
I just need to add the remaining bits of insulation around the tricky, sloping corners, then wrap and seal them before laying some plywood to use as walls. My electrician has been waiting for me to do so since May.
I tried it out during the winter and it was surprisingly cozy inside despite the missing insulation and some air gaps. It's rather toasty now in summer though.
I just, haven't found the motivation to complete it.
