Office construction in central London has grown 24% over the past six months, taking total office space under development to 9.5 million sq ft.

The latest London Office Crane Survey by Deloitte Real Estate has recorded 31 new starts contributing 4.4 million sq ft into the 9.5 million sq ft development pipeline.

Anthony Duggan, head of real estate strategy at Deloitte, said the upturn in office construction reflected 鈥渢he start of the supply response the market has been expecting鈥, after a period of decline following the completion of mega-office schemes the Cheesegrater and the Walkie Talkie.

Duggan said: 鈥淸This is] all thanks to the robust economic conditions, strength of London as a global city, tight existing office supply and high levels of leasing deals being transacted.

鈥淗owever, this increase in activity will not come in time to alter the very tight supply dynamics the office market is currently experiencing. We expect further rises in rents and more pre-let deals on schemes under construction as tenants compete for the limited amount of available space.

鈥淟ooking further ahead, we expect the development pipeline to continue to increase as developer confidence translates to more active construction sites across London.鈥

All but two of central London鈥檚 submarkets are sharing the growth. The City is powering forward with 10 new construction starts (1.7m sq ft) accounting for 39% of all new activity started in this survey, and just under half of all pre-let development taking place across central London.

The West End has seen a 24% rise in activity driven by 11 new starts in six months.

Steve Johns, head of City leasing at Deloitte Real Estate, said: 鈥淒eveloper sentiment is continuing to improve and this is good news for London鈥檚 diverse occupier base.

鈥淭he increase in new starts is the second highest we鈥檝e recorded in 20 years. Nevertheless, a third of this space has already found tenants, leaving 22 of the new starts as speculative development schemes.

鈥淭here is no need to sound the alarm bells just yet as the 9.5m sq ft development pipeline is only slightly above the average level of activity recorded in the past 10 years. Of this, 37% is already pre-let.鈥
