Safe, buildable design that meets regulations

Once your design is agreed, the first step is making sure it can actually be built and built safely. Our structural engineering partners calculate what’s needed to support the design, from beams and load paths to foundations. You’ll get clear structural drawings and details your builder can rely on, helping the construction run smoothly and safely.

We can also prepare the drawings and specifications required for building control approval. These ensure your project meets all legal standards for safety, energy efficiency, drainage, fire protection, and more. With fully compliant, easy-to-follow documents, your builder knows exactly what’s required, reducing risk, avoiding delays, and keeping everything on the right side of the regulations.

Why is structural engineering important when renovating your home?

Good design isn’t just about how a space looks; it has to work in reality, too. Structural engineering ensures your project is safe and structurally sound, whether you’re removing walls, adding extensions, converting lofts, or opening up spaces.

We handle:

  • Structural calculations
  • Steel beam (RSJ) design and layout
  • Foundation design
  • Foundation piling
  • Load-bearing wall analysis
  • Roof structure
  • Suspended ground bearing slab
  • Retaining walls

Every project is checked and calculated by trusted qualified structural engineers we’ve worked with for years.

Building regulations made simple

Almost every project needs to comply with building regulations. These rules ensure your home is safe, energy-efficient, and built properly. We prepare and submit Building Regulation drawings that meet legal standards, covering:

  • Structure
  • Fire safety
  • Insulation and energy performance
  • Ventilation
  • Drainage
  • Sound and thermal performance
  • Stairs and access
  • Materials and workmanship

We also liaise with Building Control (private or local authority) to answer queries and keep things moving smoothly.

Smooth handover to build

We stay involved through this stage to ensure everything works together – structure, design and budget. If we’re managing your full project, we carry these drawings through to tender and into build, so everything connects seamlessly, bringing your vision to life.

Frequently Asked Questions

Anything involving structural changes (removing walls, extensions, lofts) will need structural calculations.
An application usually takes around 2 weeks, depending on complexity and response times from Building Control.
Builders can apply for Building Regulation approval, but they can’t legally produce structural calculations, and DIY drawings often lead to delays or failed inspections. It’s best done properly by experts.
We handle Building Control queries and update drawings if needed so there’s no stress for you.
We don’t recommend starting before building control has been applied for otherwise you risk being stopped mid-build and facing extra costs.
