House Extensions

At 1st Builders Cambridge, we are extremely adept in all aspects of professional building work and specialise in house extensions. While hugely increasing the value of your home, a house extension can provide you with a large, open-plan contemporary kitchen, a new ground floor bathroom, or simply just a modern and practical way of expanding your living space.

1st Builders Cambridge can offer a new single storey extension, a two (or multi) storey extension, or an extension built over an already existing structure, such as a garage. During the initial stages, we will work closely with you on various designs and can apply for planning permission to your local authorities on your behalf.

1st Builders Cambridge aim for complete customer satisfaction and always try to exceed our customers’ expectations. We pride ourselves on the fact that the majority of our house extension work comes from recommendations from previous customers.

Have a look at some of our recent house extensions below and feel free to contact us for a free quotation. We will be glad to assist you in planning and building a beautiful, contemporary house extension.
