Three 鈥榢ey areas of change鈥 earmarked for new development as Square Mile eyes transformation into cultural and leisure destination
The City of London鈥檚 guidance for development in the Square Mile over the next 16 years has passed a key planning hurdle.
The City Plan 2040, which sets out how the area will become a 鈥渟even-day-a-week cultural and leisure destination鈥, has been overwhelmingly approved by the City鈥檚 planning and transportation committee.
It is the first of three committee votes it must pass before the document, which has been in development for almost a decade, is published for public engagement and sent to the secretary of state for consideration.
The plan includes an ambition for more than 1.2 million sq m of new office space by 2040, with most of it to be built in three 鈥榢ey areas of change鈥 earmarked for tall buildings.
Most of the new floorspace will be mopped up by the City cluster, the group of towers in the eastern half of the City where Stanhope wants to build the 74-storey 1 Undershaft, which was submitted for planning last month.
This will be supplemented by smaller areas deemed suitable for new development around Fleet Street and Liverpool Street.
A new contour map included in a draft document for the 2040 plan sets out the maximum heights of tall buildings in the City cluster, which has a central peak around 1 Undershaft of 300m, although Eric Parry鈥檚 proposals for the site would rise to more than 309m.

A much smaller area in the west of the City around Holborn and Fleet Street is the only other area where tall buildings would be allowed under the plan, with a stricter height limit of no more than 90m.
The City of London Corporation said maximum building heights in these two areas had been calculated using extensive three dimensional modelling and assessments of potential impacts on St Paul鈥檚 Cathedral and the Tower of London.
The study found that all parts of the City, which has nearly 600 listed buildings, is highly sensitive to tall buildings, with only the City cluster and Fleet Street areas having a slightly lesser sensitivity.
Towers in the two approved areas must achieve an 鈥渆xemplar standard of architectural鈥 and enhance the City鈥檚 skyline, according to design guidance included in the document.
They must also make a 鈥減ositive contribution to the townscape character鈥 of the City and create a 鈥渉igh quality experience at street level鈥.
Office developments in general must take a 鈥榬etrofit first鈥 approach, prioritising the refurbishment of existing space over newbuild options in a policy assigned 鈥渟ignificant importance鈥 in the plan.
鈥淎n understanding of the potential for retaining and retrofitting existing buildings should鈥 be the starting point for appraising site options, alongside a robust analysis of the whole lifecycle carbon of different development approaches,鈥 the document says.
All major schemes will need to undertake an assessment of the viability of retrofit on sites, and where new buildings are found to be the most suitable approach, they must be of a high standard of low carbon development which 鈥渄rives forward best practice beyond standard approaches and contributes to wider sustainability improvements in the area鈥.
All large developments will be required to achieve a minimum BREEAM rating of 鈥渆xcellent鈥, and aim for 鈥渙utstanding鈥, and a minimum five star NABERS UK rating.
The City has previously announced an ambition for a 鈥渘et zero Square Mile鈥 by 2040, 10 years ahead of the government鈥檚 target for the rest of the UK.
The plan also aims to make the City鈥檚 riverside play an 鈥渆nhanced role鈥 for the City with more leisure, culture and recreation destinations with enhanced greening and connectivity.
The Corporation鈥檚 chairman Shravan Joshi said: 鈥淭he City of London is like nowhere else on earth. A global economic powerhouse, and an ancient city, a centre of collaboration and innovation for the hundreds of thousands of people who work here, as well as a destination for visitors and tourists who come to experience our unparalleled culture and heritage.鈥
鈥淭he City of today has enormous strengths but, like all successful places, it needs to adapt, to change and to grow.
鈥淭he City Plan 2040 will help to shape the built environment in ways that rise to the challenges of our time while making the most of the many strengths of the Square Mile.鈥
A public consultation on the draft plan will be launched this spring, with an examination by an independent planning inspector following later in the year.
