Get Answers to Your Questions

The FAQs below may answer some of your questions, but please get in touch with any queries or to discuss your project.

What is off-site construction and how does it work for home extensions?

Off-site construction refers to the process where key building components are constructed in a controlled, off-site setting before being transported and assembled on-site. For home extensions, this means that we build timber-framed panels at our facility with precision, reducing construction time and ensuring high quality. Once the panels are ready, they are delivered to your location and swiftly assembled, minimizing disruption to your daily life.

How long does it typically take to complete an off-site home extension?

An off-site home extension can be completed significantly faster than traditional methods. The off-site construction at our facility typically takes 1-2 weeks. Once the panels are ready and delivered, the on-site assembly will take up to 3 weeks. This efficiency in time allows you to enjoy your extended home much sooner compared to conventional building methods.

Will there be any disruption to my home life during the construction process?

One of the key advantages of off-site construction is the minimal disruption it causes to your home life. Since most of the work takes place at our facility, your home is open to the elements and impacted by construction activities for a much, much shorter period. The on-site assembly process can then be as quick and unobtrusive as possible, ensuring your comfort and privacy remain largely undisturbed.

Can I customise the design of my home extension to suit me and/or can you provide an extension to my existing drawings/ permissions?

Absolutely, customisation is one of the strengths of our off-site construction process. We design and build panels to precisely meet your needs and specifications. Whether you have existing architectural drawings or are starting from scratch, we work with you to adapt and enhance your design within any planning permissions. Our expert team is here to help bring your vision to life, ensuring a seamless blend with your existing home.
