We are planning a small extension but complete ground floor remodelling. We want an architect to design it, and we found one whose work we love. However, I am worried that actually building her work will cost more - she uses a lot of bespoke joinery for windows, benches, etc, and I’m afraid we’ll end up paying over the top for something that won’t add lots of value. We’re ok to pay her fees but really worried she’ll design something super expensive to build. Is this a thing? Has anyone had experience of using a “fancy” architect?
