I love the concept because modularity is clever. You can build many many setups with a few pieces, and it's easy to ship!

I've been shopping for a desk in Oxford & London and I was not satisfied with what I saw. Great timing, I will consider de-sk.

I'd love to see adjustable height. Maybe not with an engine, as that would make the desk too heavy to ship and too expensive or complex. I think a crank handle system would be enough for small frames.

I'd also love to see the possibility of buying solid wood modules, like solid birch, instead of plywood.

PS: You should maybe have a solution for the annoyance of writing over tiny gaps. It doesn't bother me as I always write on top of a leather pad, but I can bother others. Good luck.
