The Conservatives promised to give local communities a greater say over planning decisions and halt development on green sites.

The Tories are right to prioritise brownfield but I am disappointed they have not heeded the call to equalise VAT

The Tories have pledged to 鈥渓iberate local government鈥� by giving local communities greater involvement in the planning process. The party has also focused on social housing, saying it will extend the right to buy to tenants of housing associations as part of a drive to boost shared ownership schemes.

The party promised to promote development on brownfield sites, rather than building on green areas, and said it would offer greater incentives to make homes more energy efficient.

The manifesto states: 鈥淲e will call a halt to Labour鈥檚 plans to concrete over our green fields. We will promote development on brownfield sites and establish more green belts with tighter development rules.鈥�

RIBA president George Ferguson welcomed the Conservatives鈥� focus on brownfield development, but said he was disappointed with omissions from the manifesto.

He said: 鈥淭he Conservatives are right to prioritise brownfield development but I am disappointed they have not heeded the call by the RIBA and others to equalise VAT on all forms of construction to encourage regeneration.鈥�
