A UK subsidiary of Arup Group has signed an agreement to pre-let 133,600 sq ft at Derwent London’s 80 Charlotte Street W1, on completion of the development in the second half of 2019. Simultaneously, the Group has agreed a conditional put and call option to sell 8 Fitzroy Street W1 for £197m to Arup, who occupy the entire building, with completion expected on 23 June 2017.

At 80 Charlotte Street, Arup has agreed a 20-year lease on the first to third floors as well as part of the ground and lower ground floor space. The initial annual rent of £9.74m represents £75 per sq ft on the main office floors. The rent will rise by 2.25% per annum for the first 15 years, at which point there is an upward only open market review. In return, Arup will receive rental incentives equivalent to 33 months’ rent free. After allowing for the impact of indexation, the average rent over the first five years is in line with our June and December 2016 ERVs. Arup also has an option to take the 40,700 sq ft fourth floor.


80 Charlotte Street W1 is the Group’s largest current development totalling 380,000 sq ft of mixed office, residential and retail use1. Arup will take 41% of the main building which comprises 309,000 sq ft offices and 14,000 sq ft of retail space. This is designed to be multi-let with separate entrances and large, flexible floorplates with extensive terraces. There will also be a new publicly accessible pocket park.

8 Fitzroy Street W1 is a freehold property comprising 147,900 sq ft fully let to Arup until 2033. The rent is £7.2m, and is subject to annual stepped increases until 2021 when there would be an upward only open market rent review. The disposal price reflects a purchaser’s net initial yield of 3.4% and is at a 2.8% premium before costs to the property’s book value in December 2016.

John Burns, Chief Executive Officer of Derwent London, said:

“We are delighted to continue our long standing and close relationship with Arup in this mutually beneficial transaction. We have been able to facilitate the upgrade of Arup’s London headquarters and Arup will be the first occupier anchoring our major 80 Charlotte Street development. This complex transaction further de-risks Derwent London’s development programme, and is evidence of our asset management and letting skills, the desirability of our product and the advantage of owning a cluster of property in an attractive location.”

David Whittleton, Deputy Chair and Group COO of Arup Group, commented:

“This innovative deal offers real benefits to both Derwent and Arup, and was possible because of the strong and trusting relationship developed between our firms over many years. Arup is very pleased to have been able to secure its London future in quality space in the rapidly improving Fitzrovia area, where the firm has been based since inception, at attractive and predictable costs. We look forward to many more collaborations in the years ahead.”
