I'm guessing you start with the roof and work your way down ?
So roof, electrics, any damp, windows, central heating/boilers.
Then I'm thinking bathrooms one at a time (3 in total).
Children's bedrooms x 4, living room, garden, kitchen.
Master bedroom, study, hallway.
By which point I expect to be retired or dead.
Has anyone else done a big project, any tips ?
