Enter their latest project: a sleek, airy, 10x12-foot A-frame mini-cabin, which the couple built earlier this year over a period of two weekends, and all out of easily sourced materials. The cost? A relatively miniscule $2,500. On their website, Elevated Spaces, which the couple launched shortly after the 2020 fire, Waldman and Fiffer are selling plans to enable even a DIY novice to build their own version of the A-frame cabin.
