Stem & Agate Ltd is a specialist construction company based in London, working on renovation and refurbishment of fine residential and commercial properties.

Our company was established in 2010 and has been growing since, expanding its portfolio and gaining expertise in design and build projects, loft and basement conversions, including restoration works and remodelling of listed buildings. Our services also include extensions, bespoke joinery, M&E, windows, landscaping and decoration.

We have a strong team of experienced project managers and highly skilled workers, that take pride in their work and craftsmanship. Our biggest strength is attention to detail and comprehensive client care, that helped our company grow mainly through referrals.

We ensure that every aspect of each project is done properly and in a timely manner. We do this by preparing detailed and realistic costings and programme prior to beginning of the works, and constantly monitoring the progress.  We also offer continues support during the planning and implementation stages helping our clients and architects to find the most efficient and cost-effective solutions. 

Please have a look at our most recent Pojects and get in touch if you would like to discuss your ideas, or simply send us the details of the project to receive a free estimate.
