We've recently bought a house that needs a total refurb, and we're adding an extension. It's long been a dream, but now it's reality, I'm floundering a bit. Where to even start with looking at things? I find myself comparing boilers one minute, then browsing upholstery fabric the next whilst stressing about wall lights in the back of my mind. 
There's so much choice I seem to keep coming back to the same few sites; John Lewis, Made etc. There must be so many gems I'm missing - please give me your recommendations for both the nuts and bolts of refurbishment and the prettification later on. My preferred style is midcentury modern and clean lines, but would love a distracting nosy at anything!
