Who We Are

Onslow Construction is an independent Surrey based building company that specialises in the delivery of high-quality, bespoke home renovations and extensions. Our experience and expertise are there to provide our customers with a professional and personable service at every step.

With 70 years of collective design, development and building experience, John set up Onslow Construction with the sole aim of delivering high quality building projects that provide their customers with beautiful spaces they love. At the core of everything we do is an unwavering commitment to customer service and an uncompromising dedication to attention to detail.

We pride ourselves on every member of our team and only work with sub-contractors who share the same passion for property and high standards of work as us. This means you can take comfort in the fact that collectively we will go above and beyond to make your design vision a reality.

We fully understand the disruptions, financial strains, and stress that a building project can bring with it… we therefore approach every project with the clear objective of making the process as easy as possible for you.

We believe in reliability and honest communication, which mixed with our project delivery has gained us many referrals that we are very proud of.

Our portfolio of over a hundred successfully completed works includes refurbishments, conversion, extensions, newbuilds and even Grade 1 listed heritage works.
