The Mayor of London also announced that Harrow Town Centre will receive over £1.5 million to help create a new business and community infrastructure.
According to the Mayor's office, the first project will intensify workspace usage at Artisan Place for new businesses, by fitting out the old Windsor & Newton offices to create a creative/tech workspace with ground floor cafe, co-working area and 'grow-up' space on upper floors.
The second project will deliver a new town square for Wealdstone for events/markets and to reinvigorate business/community partnership.
Works will include public realm and shop-front improvements, and establishing a new market.
The third project will focus on business survival and growth, including establishing a Wealdstone town team.
In Hillingdon, after securing the investment, Hillingdon Council will set aside the money to rejuvenate the High Street, Vine Street, Windsor Street, and to develop the space outside the Civic Centre for more community use.
The improvement work will be completed in line with the London Regeneration Fund’s timescale between April 2016 and April 2018.
The Mayor of London Boris Johnson and MP for Uxbridge and South Ruislip , said: “High streets and town centres the length and breadth of London are a hive of economic activity fuelled by creative minds.
“It’s important that we make sure they continue to meet the needs of a rapidly evolving city and the talented people who are key to its future success.
“It is fantastic to see so many applicants to this fund, offering innovative ways to nurture and support the dynamism and creativity that will power our economy in the years ahead.”
The London Regeneration Fund aims to make the most of the city’s wealth of talent in creativity and technology, and the Hillingdon project “Uxbridge Change of Heart” secured £800,000, with a tough competition from 69 other applicants.
Councillor Douglas Mills , Cabinet Member for Regeneration, said: “Being awarded the London Regeneration Fund means that we are on right path to create a thriving and vibrant town centre for Uxbridge.
“The changes being planned reinforce our commitment to the town and will encourage the business community to make further investment in Uxbridge, retaining it as a key component of our Borough".
The improvement work is said to complement much greater private sector investment underway over the next few years, including the former RAF Uxbridge , St Andrews, Charter Place with Primark opening together with “Uxbridge Change of Heart”.
Hillingdon Council say the cash boost will bring the “renewal of the Uxbridge town centre as well as creating many new job opportunities”.
