So much more than a contractor,
we are your project partner...

Conveniently located on the Essex/Suffolk border and predominantly working in those counties, we have been creating perfect living, leisure and workspace, from extensions and conversions to new builds, for more than twenty years. 

Our team consists of skilled tradespeople across multiple disciplines from groundworks, construction, plumbing and electrics to final finish and landscaping. Having these skills in-house alongside our procurement, quantity surveying and project team means we really can offer a turnkey service for our customers.

We appreciate the investment you are making, so we will take the time to listen to you to understand your needs. Whether you want to create more space, remodel the space you have, or build a brand new property, we can design and build the perfect solution.

Our collaborative approach does not just apply to the planning and specification stages. We believe it is crucial that communication channels remain open throughout the project to ensure that our standards are in line with your expectations.

Having in-house procurement and quantity surveying ensures that when you receive your quotation, we have specified and costed everything down to the last nail. That means you’ll get a fixed-price quotation for your project, and a timeline you can trust.

Finally, we understand that our construction site is also your home, so we aim for minimal disruption. A tidy site, a punctual, polite workforce, and keeping your home accessible, usable, and safe throughout are just part of the service when you work with us.

John is an amazing character with a strong family and team behind him. From the very start our minds were put at ease by John and his professional attitude towards the extension we wanted built. The standard of service and work provided by John and his team was excellent and the finish product is a home that we love.  Every step of the build was explained and if ever there was question we wanted answered, John and his team were only a phone call away.…


John O’Connell was recommended to me by a friend and I am so glad that I chose them to renovate my home. After meeting John and discussing the project, he made further suggestions on how I could benefit more from the renovation work, and his ideas where fantastic! He suggested putting in under floor heating and recommended a shade of paint that would look nice on the window ledges. His professional opinion gave me confidence that he knew exactly what he was doing. I listened…


Once moved into our new house, one of the first things we decided was that we needed to have a garage built. Not only to house one of the cars, but be used as a store for garden tools etc. We obtained planning permission and asked John O’Connell to quote. John arrived at our house and we discussed the plans, showed him the site for the garage and almost by return sent us a very detailed and professional quotation for the work required. Prior to…
