Granny Annex

Why build a Granny Annex

The Granny Annexes we build are suitable for many customers for an array of reasons. Some simply need more space for when guests visit, others prefer to keep family members close to home whatever the reason, a Granny Annexe provides a cost effective and attractive solution. Our Granny Annexes are all Timber Frame constructions, that are fully insulated so make for cosy (and energy efficient) year round living. Each Annex is tailor made to suit your needs and lifestyle – we even help advise on building controls and planning permission so the process couldn’t be simpler.

Building a Granny Annex


Nothing we do is pre-fabricated and we will construct your Annex to suit your specific requirements – We are a UK based company (with Scandinavian roots) and our warehouse is in Byfleet so our expert carpenters, and office team are always on hand to support you.
