The design
One building, many sizes.
Anthracite steel cladding, a glazed gable and a timber deck: the same building, shown in the supplier's own visualisations.
Don Modular Homes publishes one rate per square metre for every size. PlotNua has not verified those prices to its pricing standard, so it does not show them here: each reads “Price not currently verified”. The sizes and what the supplier includes are below; the cost of your project is confirmed only in the supplier’s written quote.

The whole cost
Ask for a written quote that includes the base, delivery, crane, installation, connections and VAT, so you can compare like with like.
Planning
A garden room that is not lived in can be exempt from planning permission within set limits. A home in the garden is different: depending on its size, it may need permission or a notification under the newer rules for detached units, and every condition applies. Don Modular Homes publishes its own guidance; treat it as the supplier's view and check your plans with your local authority.
