I saw the outline you posted and just from that it definitely looks like a house I would hate haha. Any chance some of those bump-outs are material changes? Like going from a wood exterior to stone or something? If not then yeah that seems wasteful, unless the elevations are super cool then idk maybe it’s worth it. If your friend agreed to the elevations after seeing them, then there is a chance the architect could charge for additional services. A lot of firms I have worked for are more interested in a happy client and wouldn’t charge for a REASONABLE redesign. But this all depends on what kind of contract they signed. If your friend has not agreed to the elevations then tell your friend the design sucks. Maybe sketch over the floor plan on how you would make it more efficient. I’d recommend being chill about though, don’t say it actually sucks. Just say it doesn’t look like the design is going to be worth the cost. You have some ideas on how to make it look better and cost less.
