Home Extensions North London
How Much Will My House Extension Cost in London?
The cost of your house extension will depend on complexity of the project and the part of London. Again, the closer to zone 1, the more expensive the logistics and the more restriction complications.
The roof structure will also influence the cost – a flat roof structure is likely to be cheaper than a crown roof structure.
Another factor that will influence cost is the depth of the foundations. If there are trees close to your future extension, the foundation may need to be excavated to 2.5m deep. A piling may even need to be considered.
The approximate cost of an extension is somewhere between £1700 and £2000 p/m2.
