Developers for a controversial 200 home site were ordered to stop work after leaving the road in a filthy state.
The former Middlesex University site at Cat Hill, on the border of Enfield and Barnet has been hotly contested by developers London and Quadrant, and protesters against the 231-home redevelopment.
Enfield Borough Council ordered L&Q to stop their work after they visited to site on August 7, to discover the developers had left Cat Hill in a mess.
The authority told L&Q vehicle movements on and off the site to stop until the mess had been cleared.
Enfield Council’s cabinet member for environment and community safety, Councillor Chris Bond, said: “We aren’t going to allow developers to scatter building site debris all over our roads because they can’t be bothered to install proper cleaning facilities for vehicles leaving their sites, it’s not acceptable and we made our views very clear in this case.
“Residents living near this site have to tolerate the building work going on, they shouldn’t have to put up with mud and other rubbish all over the roads outside their house.
"Enfield Council is determined to minimise the impact of building works on residents and this case demonstrates we will intervene to make developers comply with the conditions set out in their construction methodology statements when that is not the case.”
Protesters are continuing battle against the development and are awaiting the verdict from court on whether squatters on the former university site, can remain there.
The mess has now been cleared and an L&Q spokesman said: “Work is continuing on our Cat Hill development, to create well-designed homes that match the character of the local area. We remain committed to ensuring that our contractors’ work complies with the important rules and regulations that govern all construction schemes.”
