Definitive Construction

Extensions, Carpentry & Oak Frames

Quality Building & Joinery

Definitive construction are a family run Berkshire based firm of builders and craftsmen.  As well as traditional buildings and extensions we also specialise in carpentry and oak framed buildings.  We cover all aspects of the work from design to completion.

We pride ourselves on the high quality of our work and materials.  Whether you need us to take care of smaller scale bespoke carpentry, a custom oak frame conservatory, a building extension or traditional carpentry for a listed building you will get the same care and attention to detail.  Our testimonials are evidence of our dedication to customer satisfaction.

We cover all aspects of the work from design to finishing.  As part of the design we consider all issues that will impact the longer term usability and maintenance.  We can produce 2 or 3 dimensional drawings to help you articulate your requirements.  Our skills and technologies mean we have the efficiencies and process normally associated with larger companies.
