Professional Property Developers

A good property extension should do much more than just provide you and your family with extra space. Done well, an extension can transform your home by opening it up, flooding it with light and transforming the way you live. A well-designed extension can also add extra character and style to your home bringing it up to date and adding considerable value, too.

Whether you want a large extension to open up your living space or to create a functional office, gym or playroom, we can build the perfect new space for your needs.


At Top Notch Developments, we know that each property and every person is different. That’s why we work with you, understanding your specific requirements, ideas and preferences, to create the perfect home extension for you. Whether you want to create a large open plan kitchen with bifold doors onto the garden or to create an office space away from the bustle of family life, we can ensure you achieve the extension of your dreams.

Building an extension is not always a matter of just adding an extra room. With careful planning and some structural work, such as blocking up doorways or opening up walls it is possible to completely change the look and feel of your home.

We can help you create an extension that maximises the space and functionality of your home, whether that is a side extension, rear extension, single or double story or loft conversion. Whatever your vision for your home, we can make it a reality.


As professional builders, we bring many years of experience to your project to ensure everything from the planning to the finish goes smoothly.

We blend traditional joinery and building skills with modern-day designs and tools, to create beautiful extensions tailor-made for you.  Our team have the skills and experience to take on your entire project from start to finish. We can complete every aspect of the build from foundations and drainage to tiling and painting. In addition, we can liaise with the necessary authorities to ensure there are no hold-ups in your project.

We do all this while ensuring that the project is completed on time, within the specified budget and with minimal disruption to you and your family.

Our guarantee

We care about our work and our pledge is to stay in the job until you’re happy. No ifs, no buts. We guarantee that we will answer any questions you might have during the build and ensure that you are 100% happy throughout the transformation of your home.
