Kitchen Extension in Brentwood

What our customers have to say:

"A huge thanks to Dave, Julian, George, Vern and everyone involved in building our extension. They have created us a large 50 square metre open plan kitchen, dining and lounge area and we look forward to enjoying it as a family for many years to come. The job was started exactly when agreed and the quality of workmanship has been first rate throughout the build. Communication was excellent and we could always contact someone if we needed to. There were some unforeseen issues with the existing part of the house and the way it was dealt with by Dave and the team is a true testament to the sheer professionalism of this firm. I would not hesitate to recommend Bush Builders and we will definitely be using them for further projects."

"Dave and his guys built us a very large extension across the whole length of our house. One of the largest builds the team had done, and we couldn't be happier. Dave was realistic and is the only tradesman I have met who gets back to you each time you message or call. The guys are an established team and clearly work well together, minimising delays as much as possible.

We are absolutely thrilled with our extension, quality of the work and all interactions with Dave and the guys Could not recommend strongly enough."

What are the benefits of building a house extension?

Does your dream house include a playroom for your kids, an en-suite bedroom, or perhaps a quiet corner office corner for you to work? Many people automatically assume that they need to move house to get the extra space they need, but we all know that moving house can be very expensive. Before you start perusing the estate agent ads, have you thought about a house extension on your current home?

If you’re considering a house extension in Essex, you’ve come to the right place.

With rising house prices and the well-known stresses and hidden costs of moving, extensions are a popular solution to increase the living space in your home. Whether your life or family has outgrown your home, or you just fancy an upgrade, a well-planned extension can come at a surprisingly low cost and can increase the value of your home far above the cost of the extension. So many people are amazed when they see the difference a well-designed rear extension or kitchen extension can make to their home.


Adding an extension offers an almost unlimited range of possibilities to suit your needs and we have built all kinds of house extensions in Essex. Everything from the type of extension, (rear extensions, loft conversions, garage conversions, conservatories) to how you make use of the extra space (kitchens, bathrooms, bedrooms, offices etc) can be discussed with our experts and delivered to the highest standards.
