Your security is our priority; that’s why we install all our house extensions with multi-point locking systems to keep you feeling protected in your home. The double glazing we use is also extremely durable and hard wearing, creating a tough barrier for any forced entry attempts. We want to keep Basildon homeowners as safe as possible.

Thermal Efficiency

House extensions are the perfect alternative to a conservatory as they maintain a comfortable optimum temperature all year round. They are neither too hot nor too cold, meaning they can be used all year round. Our extensions trap pockets of warm air in their durable panels to create the perfect living environment throughout the year.
