The WAF is not incompatible with this way of thinking - it just requires you to extend your creative reach to come up with solutions that are also aesthetically pleasing.
Me, I like to work with negative space when I’m making furniture - take stuff away to create something, add as little as necessary.
I also have my fair share of Heath Robinson contraptions, but as long as I keep them invisible (i.e. tucked away in a shed or a hutch quietly fulfilling its function) the WAF is fulfilled - and I have a stringent set of controls and policies set out by the SWAMBO.
Our bed is made out of leftover construction lumber and OSBs, but it’s very pretty, as it’s also made out of a bunch of walnut veneer doors I found by the roadside. Our kitchen is built from scrap wood from a skip, and the countertops are upside down concrete pavers with a tadelakt topcoat. The sink is a rock I took an angle grinder to. The faucets came from a “5 bits for €1” box of junk. People keep asking me who designed it, where did I buy X, Y, Z.
So, yeah. There’s no incompatibility - I started with the kind of quick and dirty hacks the roommate does as a student - but now that I’m pushing 40, I prefer to execute my stingy projects with quality.
