Architects, Extension Builders, Refurbishment Specialist
Sigma Construction UK Ltd, the London builders, offer a design and build service.
Whatever your needs, from house extension, loft conversion or flat improvement to a complete house refurbishment, our team of builders guarantee a first class service.
Thanks to our in-house architectural and building team we can provide a complete facility, from inception to completion. We also strive to provide a seamless transition from the initial idea through preparation of drawings and planning application to construction and completion.


The design and build method of procurement provides the best quality and value for our clients, and is a proven alternative to traditional contracting where house owners not only need to coordinate starting and finishing dates with individual tradesmen, but also have to cope with different approaches to design and the fluctuating costs of materials and labour.
Sigma Construction, however, have an excellent track record for being the single point of responsibility in design and construction projects.
This is because we have full planning, interior design, architectural and structural capabilities, which enable us to simultaneously carry out the various aspects of a project, deliver projects faster, and thus make our services extremely cost effective.
