This is something I completed last year, along with an accompanying outdoor coffee table. The design is adapted from Fine Woodworking. For some reason, recently I’ve received some inquiries from LJs – I guess woodworkers looking for non-pressure-treated outdoor furniture; so, I’ll post it here, as well: I’ve refrained from doubling-up, so to speak..
The bench is made with Jatoba (a very hard wood, ideal for exterior applications), and is wholly mortise & tenon – about 35 in-all. The M&T are both integral and floating tenons.
This is an excellent project for anyone looking to build an outdoor bench which can withstand the elements, elegantly.
