Garden Room or Annexe?
While the terms are often used interchangeably, there is a key difference: a garden room is typically a versatile space in the garden—ideal for a home office, gym, or quiet retreat. An annexe, however, is a more substantial structure designed for independent living, often used to accommodate family members, teenagers, or visiting guests.
At Clc Home, we specialise in creating both—from standalone oak-framed garden rooms to fully designed annexes that can either connect to your home or stand independently in the garden. We also combine our modular extension systems with premium materials such as aluminium, uPVC, or oak, giving you greater flexibility in design and function.

Garden Room Office: A Dedicated Workspace
With the rise of remote working, creating a practical and professional workspace has become a priority for many homeowners. A standalone garden room or a garden room extension can provide the perfect solution for a dedicated workspace at home.
A separate room whether fully detached or divided by doors creates the quiet, professional environment needed for a better work-life balance. Your garden room can also be designed for multiple uses, maximising practicality while enhancing the overall functionality of your home.
