SINGLE STOREY EXTENSION COSTS
The scope of a single storey extension project can vary depending on a number of things, for example, is the project a garage extension, porch, or similar minor work extension; or is it a full-scale extension?

DOUBLE STOREY EXTENSION COSTS
While extending on multiple floors of a home clearly adds a new level of complexity to a project, that doesn’t mean your costs multiply by the number of floors you’re adding.
The cost of the project of a multi-storey extension per square metre is only slightly higher compared to single storeys, and you save a lot of money by expanding multiple floors at once, rather than separate projects down the line.
This table with give you a rough idea of what you can expect in terms of price.

LOFT CONVERSION COSTS
Loft conversions are one of the cheapest ways to expand the usable space of your home.
Most homes will already have a loft area, but one that is non-functional or only used for storage. In these cases, there’s not much point in making a home extension outwards as it’s much more cost effective to simply convert this into liveable space.
The table below shows estimated prices for loft conversion projects in the South East.
