6. Add a garden room
Adding a garden room is much less hassle than building an extension. They’re also versatile – you can use one as an office, playroom or even a guest room. Prices vary enormously, but you can expect to pay around £6,500. And if you live in Surrey, it could add over £35,000 to your home’s value.
7. Convert the under-stairs cupboard into a downstairs loo
Depending on where you live, this is potentially a great way to increase the value of your home. According to the Federation of Master Builders, it’s a seven-day job that should cost around £2,600. But if you live in Dartmoor, it will add nearly £15,500 to the value of your house.
