A seriously ill March man has urged developers to stick to its plan to install bollards outside his home to stop it becoming a rat run for traffic.

Jason Blake, 30, has a rare life-threatening condition and is waiting to undergo a medical world-first to try and improve his quality of life.

Mr Blake, who lives with full-time carer Paul Brightey in a Roddons-owned bungalow in Lake Close, claims the housing association reneged in a promise to install bollards, blocking off the narrow roadway outside his home.

Roddons, however, says the bollards plan is currently being considered by highways officials.

The roadway is one vehicle wide, there is no footpath, and Mr Blake’s front door opens almost directly on to it.

He is concerned it will become more dangerous as the 60-plus homes on the development become occupied.

Mr Brightey said: “It is already quite busy with cars and vans whizzing past, but it is only going to get worse as the houses and flats are filled.

“A handful of homes in West End have a legal right of way to use the road and they have all agreed to bollards being installed with them being allocated keys so they can use it when they want.”

NE Cambs MP Steve Barclay has also contacted Roddons to find out whether highways officers have approved the bollards.

Mr Barclay said: “It is not wide enough for two vehicles and once the development is complete it could easily become a rat run for residents.”

Anne Brighton, managing director at Circle Housing Roddons, said: “We apologise for any confusion that’s been caused over this matter.

“As we don’t own the road, we have to consult with various organisations about installing bollards and it is currently under consideration by the highways department of Cambridgeshire County Council. We visited Mr Blake and his carer last week to explain this and discuss his future needs.”

• Mr Blake was diagnosed with relapsing polychonditis 10 years ago. The condition means Mr Blake’s own immune system attacks cartilage in his body and has weakened his trachea to such an extent he needs a special machine to keep him alive when he sleeps to help him breathe.

He is awaiting pioneering stem cell treatment and a bone marrow transplant to help treat the condition. The world-first procedure will see Mr Blake undergo a transplant using a trachea grown from his own stem cells.

Once the treatment is carried out Mr Blake will need constant medical attention for many months, making easy access to his home vital.
