A cellar sitting under a house doing nothing but storing old paint tins and a broken hoover is one of the more wasteful things a homeowner can own. It's already built, already heated by the ground around it, and already yours. No planning battle over garden space, no scaffolding on the front of the house for six months.
New build architects London that homeowners should hire aren't just the ones with the nicest portfolio. They're the ones who stay involved past the drawing stage, understand local planning departments, and can tell you honestly what a design will cost to build before you fall in love with it. If a firm can only hand you drawings and walk away, you're still doing the hard part of the project yourself.
Most detached garages start with good intentions. The car goes in for a few months. Then storage slowly takes over. Old furniture, bikes, paint tins, and boxes from previous house moves, along with items nobody has used in years, begin to fill the space.
The agreement confirms that the proposed extension will not damage the sewer or prevent future maintenance if access is required. Without approval, a water company may object to the construction or raise concerns later if issues arise.
