Whether it is a renovation project or a new build, or extensions to your commercial or domestic property, our qualified team of skilled workers has the expertise and equipment to provide an outstanding service for you.

New Builds

When planning a new build it's important that you have a building contractor with a good reputation, qualifications and past building work experience to ensure it's completed to a high specification. We are proud to be able to deliver all these requirements whilst also going above and beyond to understand exactly what our clients need or want.

Contrasting the rough with the smooth


If you've out-grown your London home, extending your living area through a loft or basement conversion can often be a better option than buying a new house. Apart from the emotional stress of moving, you can save more than you need by avoiding Stamp duty, tax and professional fees (surveyors, lawyers etc) particularly in London where typical fees, taxes and duty can easily exceed £100,000.

House Extension

In order to gain extra space to your property in London an extension could be an excellent choice. We take into account all considerations that are involved with the project to avoid any delays and other obstacles so that we complete your house extension on schedule and within budget.
