Welcome to SAS: Structural Alteration Specialists

Transforming Homes with Expert Structural Alterations

At SAS, we specialise in creating amazing indoor spaces through structural changes to properties, both domestic and commercial.

Our team of skilled tradesmen create tailor made solutions to enable you to get the most out of your property. From the very beginning of your project through to completion, we work with you to deliver a quality outcome, on time and on budget.

We work closely with structural engineers and building control to ensure your design is up to rigorous standards and will last for many years to come.

Whether you’re looking to create a kitchen-diner, extend your usable space, enlarge your living area or knock through your bathroom/W.C, we handle every stage of the structural transformation—safely, efficiently, and with absolute precision.

From a simple knock through to a complete renovation, our professional team ensure your vision becomes reality.

We are more than happy to undertake the structural elements of your build only, or carry out full renovations and anything in between.
