Two key themes of the Budget on 29 October 2018 were increasing the supply of housing and improving the health of high streets and town centres. Published with the Budget was the consultation ‘Planning reform: supporting the high street and increasing the delivery of new homes’. Also announced was the government’s ‘Open Doors’ project, aiming to help improve the vitality of town centres by facilitating meanwhile use of vacant units. The ‘Planning reform’ consultation closes on 14 January 2019. A call for applications from landlords who wish to pilot the Open Doors project closes on 31 December 2018. We have prepared a briefing for clients, summarising key proposals that will be of interest to retail landlords, developers and advisers and assessing how these might impact new or existing developments and the lettings of these assets.
