Is the Perfect Manhole the perfect answer to self-build?

One of the UK’s very first ‘self-build supersites’ which sees a partnership between Buildstore, Kingspan, Potton Homes and developer Mark Ward has begun at French Fields in St Helens. The Government supported, self-build project is a two acre site that is being transformed into eighteen individual plots, to create unique custom built detached houses, each designed and built to a customer specific requirement. Unlike self-build where the responsibility for securing land, obtaining permissions and establishing groundworks lies with the individual self-builder, this custom build proposition delivers fully serviced plots, ready to build on, with access and services in place. Developer, Mark Ward has utilised a wide range of CPM precast concrete drainage products including the Perfect Manhole system, 1800mm chamber rings and 750mm pipes and by working together with Craig Evans, CPM’s Regional Trading Manager has devised a more efficient individual plot drainage solution. The development includes six Perfect Manholes, each with a precast monolithic multi-inlet base unit complete with pre-formed channels and benching, the manhole’s robust design and watertight thick-walled vertical chamber rings means that it can be installed without a backfilled concrete surround, which allows the open excavation to be backfilled sooner. “One of the main advantages in the Perfect system, was the speed of delivery combined with the incredible speed of site installation”, explained Mark Ward, the Overall Project Director. “The end result is a system of flawless manholes, which enables the site infrastructure to proceed at a rapid rate, maintaining high quality workmanship through each and every stage.” The project is the first of its ‘supersite’ kind in the UK and has been inspired in get Britain building custom designed homes to the same level as the rest of Europe. At present the UK self-build market represents 10% of the housing market, whereas in Germany it’s closer to 70%.
