Mayor of London has approved plans for 1 Undershaft development.

The City of London has approved plans for the development of a 73-storey skyscraper at 1 Undershaft.

The Mayor of London will now have to decide whether to allow the Corporation to grant planning permission as recommended, or to direct refusal.

Designed by Eric Parry architects, the proposed development is for a tower with 73 storeys above ground (304.94m AOD/289.94m AGL) with 4 basements.

It will be the second tallest building in Europe after The Shard.

The building would provide offices, retail (lower ground/basement 1), a publicly accessible viewing gallery (levels 71-72), public restaurant (level 70) and ancillary basement cycle-parking, servicing and plant.

The gross floor area would be 154,100sq.m (GEA), comprising:
- 131,937sq.m offices,
- 2,178sq.m retail (Class A1-A3) (lower ground and ground)
- 2,930sq.m public viewing gallery (sui generis) (levels 71-72)
- 1,220sq.m restaurant (Class A3) (Level 70)
- 15,835sq.m ancillary areas and plant

The building by Singaporean developer Aroland Holdings would be the tallest in the City and the focal point of the Eastern Cluster, and would provide a significant increase in flexible office accommodation, supporting the strategic objective of the City of London Corporation to promote the City as the leading international financial and business centre.

The City currently provides employment for over 450,000 people. The aim is to increase the City’s office
floorspace by 1,150,000m2 gross during the period 2011-2026, to provide for an expected growth in workforce of 55,000.

The architects are planning to create a large elliptical opening in the piazza, similar to the Broadgate Circle or the Rockefeller Centre in New York. This would provide light into, and a visual link with, the public areas at lower ground floor level. Incorporated within this opening would be a dedicated cycle ramp providing access to the cycle parking at basement level 2.

In order to attract and encourage small, start-up businesses the developers have stated that they would commit to providing 25 workspaces at 50% of the market rent for their first five years in the building.

The existing 28-storey Aviva Tower was designed by architects Gollins Melvin Ward Partnership and completed in 1969. The bold rectilinear geometry and detailing was heavily influenced by Ludwig Mies van der Rohe. It has an area of publically accessible open space, St. Helen’s Square, to the south, east and west. The existing tower is 118m tall and has five levels of basement beneath.

Como has recently completed the refurbishment of Aviva’s global headquarters. Works on the project were carried out in the fully occupied building.

Como, was appointed in December 2013 to undertake the 47,000 ft2 refurbishment project for a 2-stage design and build programme. Situated in the centre of the city the offices remained fully operational throughout the renovation with the team working to temporarily relocate the executive reception and main reception areas.

In order to bring the offices in line with the new modern surrounding buildings, such as the Cheesegrater, the use of clear glass panels in the atrium and ground floor facades have helped Aviva’s vision to ‘bring the outside in’. New additions to the building such as the interactive screens, feature staircase, artwork wall and illuminated porticos will allow the client to personalise the entrance space at special occasions and events.

The scope of work included extensive renovation of the ground floor reception area, installation of specialist lighting features as well as the creation of new meeting rooms, event spaces, a gym and auditorium; which houses the largest curved LED screen in Europe.

Como worked with the client and contributing consultants to support the project from the initial planning application stage. Challenges of working with expensive pre-purchased glass and water ingress were made harder with the added complication of manoeuvring around a fully occupied building.

Zoe Moss, projects director at Como, said: “Working around a fully functional office in a busy city was a challenge however the team were more than capable of delivering the project successfully and safely.”

An Aviva spokesperson said: “We are all extremely pleased with the result. The new space significantly enhances our headquarter facilities and its visual impact in the heart of the City.”
