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?

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

Does your dream house include a playroom for your kids, an en-suite bedroom, or perhaps a quiet office corner for you to work? Have you thought about how much it would cost to move somewhere bigger?

With rising house prices and the well-known stresses of moving, extensions are a popular solution to increase living space. Whether your life or family is outgrowing your home or you just fancy an upgrade, a well-planned extension can come at a surprisingly low cost and increase the value of your home.

Building an extension offers plenty of possibilities to suit your needs, from the type of extension (rear extensions, loft conversions, garage conversions, conservatories etc) to your use of the space (kitchens, bathrooms, bedrooms, offices etc). See our gallery for some inspiration!

Our local experts can carry out a detailed survey of your property and provide specialist advice as to the best type of extension for you. If you already have plans in place we can discuss these and work with architecture drawings to come up with a tailored course of action. Alternatively, if you’re still in the early stages, we’ll help you design your new space to fit your requirements.

Whether you’re in need of another bedroom, a larger kitchen, or converting a space for some extra relaxation room, you can trust that we have the skills and experience to install it all to your specification and in compliance with up-to-date building regulations. Our team of highly experienced, friendly and professional tradesmen at Bush Builders are ready to help make your dream home a reality.
