Head of office Tim Davies said the return of speculative development was the clearest sign yet of returning confidence and predicted the area was a prime contender for ‘big shed’ projects in the pipeline.

But he added: “In spite of improved trading and a potential increase in freight levels locally it is unlikely that work on the Deep Sea Container Terminal will start in the foreseeable future.

“This is particularly disappointing as its development would provide the opportunity for Avonmouth to become a major player in the global seafreight business, especially as there are significant tracts of land surrounding the port which are capable of further development - all of which benefit from good motorway and rail connections to every part of the UK.

“As a region we already have significant infrastructure in place in terms of our road and rail network and whilst  significant port facilities are already availabke the development of the Deep Sea Con trainer Facility would massively boost the economy of the region.”

The area has already attracted major food retailers including Tesco, Co-op and Morrison and work has recently been completed on the new 600,000 sq ft plus chill and frozen facility for Asda on the former Rhodia site.

The deal is three times the size of the firm’s headline big shed deal in 2012, which saw Yankee Candle take 170,000 sq ft of space at the vacant 4Mation unit.

Combined, the two Asda  buildings are bigger than similar centres built for the supermarket giant’s rivals Tesco and Co-op. 

Other major occupiers in the area include John Lewis, Robert Wiseman Dairies, Superdrug, Honda, Keuhne and Nagel, Accolade Wines, Avon & Somerset Police and DSV.
