When it comes to selecting the suitable house extension design for your home, it is advisable to first determine whether it falls under permitted development or whether you will need planning permission. In most cases, a double-storey or single storey extension with a pitched or flat roof are the four basic variations. As an efficient and reliable design and build company, we are able to advise you regarding the planning permission and compliance with all the building regulations. Whether it’s a new room or an open plan kitchen, our Barnet builders have what it takes to deliver the perfect outcome in line with your style and preference.
The fact that a single-storey extension visually connects the house with the back garden makes it a popular option among many homeowners, who in return will benefit from the extra space and light.
While most side and single rear extensions fall under permitted development, there is always a need for planning permission when it comes to wrap-around extensions. One of our award-winning architects can help you obtain the planning application if needed. Do you want to build a gym at your home, a lounge area, or an open plan kitchen connected to your garden? We can help you achieve any of these plans.
A two-storey extension tends to be more cost-effective than single-storey ones, mostly because the foundations and the roof happen to be the most costly parts of the building process.
Our builders in Barnet, with years of experience, can build a double-storey extension either at the back or side of the home. As part of compliance with the building regulations, there will need to be a pitched roof with the same design as the existing one for a two-storey side extension. There are several things you can do with an extension, getting an extra bedroom, playroom or office are just a few of them.

I have been using Frank and his team for many years, and am always impressed by their professionalism and attention to detail. They are highly skilled and can do any job, big or small. They actually built our entire house from scratch a few years ago, and now we use them for property maintenance jobs around the house and garden. They are highly reliable, trustworthy, punctual, neat and tidy, and can do anything. Always my first port of call if there is anything to build or fix in the house. Highly recommend.
High quality, friendly and professional building service. Impressive attention to detail and admirable work ethic. Have seen a couple of their projects close hand from start to finish and can highly recommend them, especially if quality is paramount.
