More than a contractor, we are your project partner...

In the last twenty years, we have built a reputation for delivering excellence in everything we do, from those all-important first consultations, to delivering on time, and on budget.

Working in the Essex and Suffolk counties, we have gained expertise in working with historic buildings and are aware of the extra care and specialist materials that are needed when restoring listed or period properties. We have worked closely with bodies including English Heritage and have a good understanding of the legislation involved in restoring and repairing listed buildings.

If you are extending your property or designing a new build, we can work these time-honoured skills into creating brand new timber-framed and heritage style homes that have a traditional look and feel with every modern innovation built in.

Most often, our customers simply want more space, either to cater for a growing family or to create bespoke facilities such as disabled modifications. From our first discussions, we aim to design and create the perfect space for you and our customers are usually surprised at how well their new extension, conservatory or loft conversion works in to their existing property.

Our collaborative approach ensures we communicate with you throughout the project and are careful to minimise disruption. A tidy site, polite, punctual workforce and keeping your home accessible, usable and safe throughout are just part of the service when you work with us.

Most of all, we’re proud to be able to say that most of our work comes through recommendation. We look forward to working with you.

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…
