A Bright and Spacious Option

Open plan house extensions allow you to bring a living space to your home that offers an inherent brightness and spaciousness for you to enjoy. Due to a lack of obstructions, this house extension design maximises the amount of natural light coming into your home: all without any compromise to comfort or security. Alongside this, open plan house extensions naturally offer a larger floor plan. In turn, this means that they serve as the ideal place for you to entertain large groups during holidays, celebrations, gatherings, and more. Not only does this allow our open plan house extensions to be used for multiple purposes, it also means that they can add an extra tier of comfort to your property.

Other Features


Keeping the winter winds at bay while still enjoying the feeling of freedom and roominess is a signature aspect of an open plan house extension. Although bright and spacious, all of our house extensions are able to achieve cutting-edge standards of thermal efficiency. This is made possible by an energy conscious design, which works to trap in the warm air that your heating produces. In turn, this means that you’ll be able to stay warmer for a longer period of time, and you could even find yourself saving money on your heating costs.


We know that you not only want the home improvement process to go as smoothly as possible, you also want it to go as quickly as possible. This is why, unlike other companies, we offer you a dedicated project manager that is assigned to your installation until it is completed. Your manager will visit you daily to see how things are going, and they will be on hand to offer any professional advice and consultancy based on their experience. With Kirkwood, you’ll enjoy maximum quality with minimal hassle.


As there isn’t a ‘one size fits all’ house extension option, we’ll work closely with you to ensure your new addition is tailored to your exact specifications. With this in mind, we can guarantee that it will be the ideal fit for your property. Alongside this, we also offer a wide range of customisation options to help make it feel more like home. This includes everything from the shape of the windows through to your heating options, which means you can combine the best in looks and performance to create the perfect living space that is the ideal place to be no matter the weather.
