About Knowles

With over 25 years experience in specialist construction, Knowles is widely regarded as a leading expert in complex building projects in London and the Home Counties. Founded by Robin Knowles, the company has skills in construction, structural and heritage work.

As Principal Contractor, Knowles provides an all-encompassing construction service to clients and professional teams, taking a project from concept to completion and beyond. The focus on retaining many in-house specialist skills gives us the ability to be dynamic, agile and self-sufficient as we don’t rely as heavily, as others, on subcontractors.

Knowles thrives on the schemes that other contractors shy away from. Our commitment to in-house management on every project guarantees a consistent approach and the
best experience for our clients.

The established reputation of our management and in-house teams has made Knowles a trusted partner for architects, quantity surveyors, professional teams and private clients. Our long-standing presence in London and the Home Counties means that we are expertly-versed in the complexities and challenges of working with councils and privately-owned estates, including The Royal Borough of Kensington and Chelsea and Westminster Council, as well as the prestigious Grosvenor and Cadogan estates.
