Building Regulations Drawings
Planning permission gets your extension approved. Building regulations get it actually built safely, and signed off. We handle both, in-house, as part of the same fixed fee.
We know what's keeping you up at night
- “Wait, that's a separate thing?” Building regulations often surprise people who thought planning permission was the whole process.
- “Who's actually doing this?” You don't want your project handed off to a third party you've never spoken to.
- “Will my builder even understand these?” Drawings that don't match what's needed on site just cause delays.

Is building regulations approval the same as planning permission?
No — they're separate. Planning permission decides whether you can build; building regulations cover how it's built safely (structure, insulation, fire safety, ventilation). Most projects need both, even ones that don't need planning permission at all.
Do you handle building regulations yourselves, or outsource it?
We handle it in-house, as part of the same fixed fee as your design and planning work — not passed to a third party you've never spoken to.
Does every extension need building regulations approval?
Almost always, yes — even projects that fall under permitted development and don't need planning permission still need to meet building regulations. We build this into every project from the start.
How much do building regulations drawings cost?
They're included in your fixed design fee — we don't charge separately for them, and you won't get a surprise invoice partway through.
