Llewelyn Davies has unveiled its masterplan for the new Brokerstown Village, a 2,000-home development on the outskirts of Lisburn, Northern Ireland.
Covering an 85ha site, the proposals include a new primary school, community facilities and a mixed-use village square.
It is hoped work on the new urban village scheme, designed for developers the Carvill Group, will begin on site within the next few months.
The announcement comes as Llewelyn Davies, which employees more than 150 people at its headquarters in central London, has revealed it will open a new office in Belfast.
Director Patrick Clarke said: 'We have worked continuously in Northern Ireland for six years and have established an office to enable us to capitalise on the many opportunities in planning and regeneration in the province.
'The Northern Ireland office will also be pursuing opportunities in Scotland, particularly in and around Glasgow. Our Newcastle office has proved a big success for us and we are confident that we can repeat the success in Belfast,' he added.
Colin James, who has extensive urban design and architecture experience, has been appointed to lead the team in Belfast.by Richard Waite
