How much does a garden room cost?
Most garden rooms are priced based on size, insulation, finishes, and electrical work. Once we see your garden and understand how you plan to use the space, we can give you a clear, fixed quote.
Do I need planning permission for a garden room?
Many garden rooms fall under permitted development, but it depends on size and placement. We’ll advise you during the site visit so you know exactly what applies to your property.
Are your garden rooms insulated for year‑round use?
Yes — all our garden rooms are fully insulated and built to the same standard as a regular room in your home.
How long does a garden room take to build?
Most builds take just a few days once the base is prepared. Larger or more customised rooms may take slightly longer.
Can I customise the design?
Absolutely. You can choose the size, layout, cladding, windows, doors, flooring, and interior finishes.
