What do rear extension planning drawings cost in Falkirk?
As a guide, £1,000–£2,500 including VAT for a single-storey rear extension, or £2,000–£3,500 for a two-storey scheme. Planning and building warrant fees in Scotland are set nationally and by value of work; we confirm both before submitting. Ground conditions, glazing, the roof and how far the house is opened up move the final figure within the range.
Do you need planning permission for a rear extension in Falkirk?
The planning route for a rear extension in Falkirk is set by Scotland's householder rules and your council.
In Scotland an extension of more than one storey is only permitted development (Class 1B) if no part is within 10 metres of any boundary and it is no higher than the existing house, so almost every two-storey rear extension needs planning permission and a building warrant.
Scottish councils aim to decide householder applications within two months; the building warrant runs alongside.
Classes 1A and 1B do not apply in conservation areas, and listed buildings need listed building consent. Before any drawing we look up the property's history with the council, because earlier extensions and removed rights change the answer.
What are homes in Falkirk like to extend?
Post-war semis and terraces are common around Falkirk, and many have room for a single-storey rear extension within Class 1A limits.
