Key considerations for double storey home extensions
The position of your house compared to neighbours is the main factor when deciding whether this kind of addition to your property is feasible. Detached, semi-detached and end of terraces have the option of a multi-storey side extension. Planning permission is easier the more space there is.
Other aspects to think about when planning your larger house include the potential for increased cost due to unusual surroundings. Sloping ground, trees and peat/clay hike up the price of foundations. Ask your building contractor to explain potential issues. When you’re satisfied that it’s the right option overall, get onto finer details.
Average cost of double storey extension
- £80,000 upwards
The biggest option when it comes to extending your house is, unsurprisingly, the most expensive. However, the amount of value you add to your property ensures this a sound investment plus a useful addition to ground and first floors.
Figures start from £80,000, but the total double storey extension price will depend on numerous factors that influence the amount you pay. Size, of course, is paramount. Calculations are based on cost per metre of £1,500 – £2,500, which is typical of any house extension.
Take into consideration the general rule that just over half the budget covers construction work; the rest covers the interior. Opt for high-spec, luxury finishes, however, and that balance tips the other way.
Given a lot of the work is underground, preparing footings, it makes sense to utilise that cost by building up as high as you can from foundations. Planning to go up in the future and expanding the ground floor? It’s sensible to achieve both at once. Reduce costs overall and lessen the upheaval by doing it in one fell swoop.
