SG Build Contractors Ltd


We provide structural calculations, drawings, details and designs for domestic alterations, large-scale refurbishment projects, extensions, loft conversions, reinstatement work following fire, storm and flood damage, and more.

Whatever your unique requirements, we work with you to ensure the structural calculations and drawings we create are not only accurate and structurally sound, but also meet your personal requirements – all our clients are different and no solution will fit every situation, so we take our time to ensure the structural solution we create for you is tailored to your needs.

Our service include:

  • Calculations, designs and drawings for a new build project.
  • Calculations, designs and drawings for alterations to a domestic property.
  • Calculations, designs and drawings for an extension/loft conversion.

Extensions are a fantastic way to add value and space to your home without the cost and difficulties associated with moving. Whatever you want to achieve, SG can work with your architect’s drawings to design the relevant structural details to ensure the extension is structurally sound.

Alternatively, we can provide a ‘one-stop-shop’ contract administrator service – taking you from concept to completed extension – by instructing architects known to us and building contractors from our approved contractor list.

This will give you peace of mind that the whole process will be handled by experts and your project will be completed on time and within budget.
