Welcome to Gil-Don Construction

If you are looking for a House Extension, Loft Conversation or other Home Improvement in the Surrey area, Gil-Don Construction Services are here to help you! With over 25 years‘ experience and access to professional architects our service is comprehensive.

Home Extensions

We have provided customers with high quality bespoke home extensions at a very competitive price for many years.

Loft Conversions

Why not capitalise on the redundant space in your roof. Loft conversions are becoming ever more popular as a way of creating more living space and in turn adding value to your property.


Whether building a new shower cubicle, en-suite bathroom, or refurbishing an old kitchen, we can offer you advice on the design, layout and process.


Orangeries are a great way to extend your existing living space without having to move house; an orangery is often a more practical solution to add living space to your home as they are more usable throughout the winter months.
