The Extension Company Ltd are a well established building company based in Colchester, Essex. We began in 1999 and have many years experience in all aspects of the construction process. We have worked hard to build our reputation for quality service and have done so through our exceptional care and attention to detail in our projects.

The Extension Company is owned and managed by Mr Milburn and Mr Puxley, one of whom will always be on site to ensure all building works are kept on schedule with the minimum of disturbance to the client. We are a main contractor and therefore will take full responsibility for a project, covering everything from design concept to project completion. We bring in partners in specialist trades as and when required who then work under our management for the duration of their works. If you'd like, we can also offer recommendations for architects and structural engineers that we have a good working relationship with.
The Extension Company is accredited to the Federation of Master Builders and have public liability of £5 million.
Most of the building projects we undertake are in Colchester and the surrounding area, including Mersea Island Brightlingsea, Wivenhoe, Manningtree, Witham. Clacton On Sea and Braintree.
We undertake all aspects of domestic building services including: Extensions, Renovations and Refurbishments, Heritage Work, Loft and Garage Conversions, Roofing, Carpentry, Bathroom and Kitchen Fitting, Insurance Work and offer free estimates.
In terms of commercial work, we currently have a contract with the NHS in Colchester, covering projects at various NHS sites across North East Essex. With all commercial work a long established and robust health and safety system is in place and is integrated into all areas of this business.
