THE DEVELOPMENT market is set to be reinvigorated following a “game-changing” announcement on planning.

Ian Coomber, head of planning at Stiles Harold Williams, said developments had essentially been “on hiatus” as the sector awaited clarification on permitted development rights.

Planning and housing minister Brandon Lewis has now given permanent approval to the policy of allowing underused offices to be converted into flats without seeking planning permission.

First introduced in 2013, the rights were set to expire in May 2016.

In addition those who already have permission will have three years in which to complete the change of use – ending potential uncertainty for developers.

However concerns remain over the lack of commercial property space in the city.

Brighton and Hove City Council has an Article 4 direction in place to exempt parts of the centre from the relaxed laws in order to protect office space.

Some 800,000 sq ft office space – 16 per cent - has been lost in the city since planning laws were relaxed, according to the Brighton and Hove Economic Partnership.

Mr Coomber said: “This is a key announcement which we have been anticipating for some time. The development sector has been in hiatus for the past six months, with developers unsure if they could meet the strict May 2016 implementation date.

“This game changer has been well received and we expect the market to be reinvigorated with this announcement.

“Further changes to Permitted Development is expected over the coming months as the government aims to build one million new homes by 2020.”

Council leader Warren Morgan said the pressing need for homes and jobs had to be balanced.

He said: “Every planning application is considered on its merits, and there will be applications suitable for some housing.

"The planning process also enables local communities to have a say on proposals as well as giving planning officers the opportunity to negotiate community benefits and affordable housing if change of use is recommended.”
