A consortium, backed by construction heavyweight Sir Stuart Lipton, has approached the City of London with a plan to save the capital from any more over-expensive iconic towers.

The group, which includes Davis Langdon, Aedas, WSP and Hilson Moran, believes it can halve the price of commercial skyscrapers.

Lipton (pictured), founder of Stanhope, approached Davis Langdon nine months ago and 鈥渃hallenged鈥� the group to come up with a way of developing office buildings for just 拢125/ft² rather than the average 拢250/ft² they are understood to cost now.

The plan was presented to Peter Rees, London鈥檚 City planning officer, last November. Sir Stuart hopes to facilitate the construction of a pilot scheme to show how the study would work in practice, through his development company, Chelsfield Partners.

He said: 鈥淲hat I wanted to do with this study was re-evaluate why construction costs are so high and why tennant鈥檚 needs are not always taken into consideration.鈥�

锘縎ir Stuart threw the gauntlet down. How can we make the City more effective?

Steve Watts, director of Davis Langdon鈥檚 tall buildings division, has been leading the project since May. 鈥淪ir Stuart threw the gauntlet down in May last year. He explained that these landmark towers in London are all well and good, but why not come up with high-rise commercial schemes that are half the price at just 拢125/ft² for shell and core?

鈥淲e pulled a team together of about 10 people from four companies and we had to ask whether investment is directed towards the right outcomes. How can we make the City more effective? Rather than spending 拢1,000/m² on a nice facade, could that money be better spent on flexibility or sustainability? We want to show how tall buildings can be made more sustainable for the end user. Now we want to show how this would work on a real building. We are hoping that a developer might be interested in joining together to develop one.鈥�

Kamran Moazami, director at WSP, was involved in the project. He said: 鈥淭he results show you don鈥檛 need to make a building extraordinary to get planning. You just need to build it well and sustainably. It鈥檚 about how to get a building working economically.鈥�

The research also revealed that while most US buildings are now designed commercially, starting on the inside of the building working out, UK designs for London high-rise buildings are still focused on iconic facades and complex structures - which no longer make financial sense.

At the British Council for Offices鈥� conference on the Future of Offices in May, it was pointed out that occupiers will be more interested in the facilities and technology inside buildings. At the event Ken Shuttleworth, founder of Make, said: 鈥満诙瓷缜鴖 will need to be simpler on the outside but with more functional interiors.鈥�
