The smart solution
Why choose a ground floor addition
When a second storey isn’t desired or possible, extending your ground floor increases shared living space, adds a home office, or reworks your floor plan to make the most of your backyard. Several site factors can influence the cost of any extension:
Property access
How easily machinery and materials can reach the site shapes the scope of your build.
Trees
On your property or a neighbour's, which may need protection or careful removal.
Soil condition & land slope
Both affect the ease of excavation and footings for your new ground floor space.
