Thinking of Extending Your Home? Here’s What You Need to Know About Building Regulations
At Connor Ferris Architects, we work with Essex homeowners every day who are excited to extend, convert, or upgrade their property. But there’s one crucial step that often gets overlooked in the early planning stages – building regulations approval.
Whether you’re planning a single-storey rear extension in Chelmsford, a loft conversion in Billericay, or an open-plan kitchen in Brentwood, understanding building regs is vital to keeping your project legal, safe, and stress-free.
What Are Building Regulations?
Building regulations are a set of legal requirements that ensure construction work is structurally sound, energy efficient, and safe for occupants. Unlike planning permission, which considers how a building looks and its impact on the surrounding area, building regulations focus on how the work is done, including:
- Structural stability (e.g. beams, foundations)
- Fire safety
- Insulation and energy efficiency
- Ventilation and damp proofing
- Electrical and plumbing systems
- Accessibility
In short, even if you don’t need planning permission, you will almost always need building regulations approval.
Common Projects That Need Building Regulations
Most types of work will require you to notify Building Control. This includes:
- Home extensions (rear, side, wraparound)
- Loft and garage conversions
- Removing load-bearing walls
- Installing bi-fold or sliding doors
- New bathrooms and kitchens involving plumbing changes
- Converting flats or multiple occupancy buildings
Do You Need Full Plans or a Building Notice?
There are two main routes to comply with building regulations:
- Full Plans Application – Recommended for larger projects. We prepare detailed architectural drawings and submit them to Building Control before work starts.
- Building Notice – Suitable for smaller, straightforward projects. This notifies the council that you intend to start building within 48 hours. This is dealt with by an experienced builder.
At Connor Ferris Architects, we usually recommend the Full Plans route for peace of mind. It gives you and your builder a clear sign-off upfront, helping avoid surprises during construction.
How We Help Essex Clients Navigate Building Regs
Our team supports you throughout the process – from producing compliant architectural drawings to liaising directly with Building Control on your behalf.
We operate across Chelmsford, Shenfield, Ingatestone, Billericay, Wickford, and surrounding areas. We understand the quirks of each local authority and will guide you through the process with:
✅ Detailed drawings for submission
✅ Structural calculations (where needed)
✅ Project coordination with your builder

Can I Get a Completion Certificate?
Yes – and you’ll want one. A completion certificate from Building Control is essential for proving that your extension or renovation meets current building standards. It’s also a must-have if you ever plan to sell your home.
