When you’re building anything from a small extension to a full development, staying on the right side of the rules makes a big difference, and that’s where we come in. We work with self-builders, architects and developers to make sure building regulations are followed from the start. That means giving clear advice, checking your plans, and helping you avoid costly mistakes. Because we know how different councils work across the UK, we can spot local issues early. Our goal is to keep your build safe, legal and on track, so you can spend more time building and less time fixing problems.
