Stunning Mill House Extension, Cornwall
November 2019

This old Mill House in Cornwall has undergone a huge conversion and extension to become a luxurious five-bedroom home, protected by the failsafe Newton CDM System.

Simon Williams purchased the 18th Century Water Mill in 2015 with a view to renovate, develop and extend the beautiful property, located in Blowinghouse just South of Perranporth, into his private residence.

Once planning permission was gained for the required conversion and extension to transform the mill into a luxurious 5-bedroom family home, Simon liaised with CAD Architects on the design, which incorporated a waterproofing design specified by Newton.

An additional large garage with charming two-bedroom ancillary accommodation was also added to the grounds of the property, which required specialist steel and concrete foundations, given the close proximity of the water.

In order to restore the old mill and achieve a Grade 3 habitable environment, BS 8102:2009 recommends that a Type C internal cavity drain membrane system is one of the primary forms of waterproofing, as it is the most failsafe system that is least prone to defects and issues.

The Newton CDM System is also completely maintainable, and was therefore ideal for the 18th Century structure, considering that Williams Creative Homes did not want to compromise the external appearance of the thick stone walls.

The proximity of the river also meant that there was a high risk of water ingress, however Newton's robust cavity drain waterproofing is designed to capture water using Newton 508 membrane on the walls, then drain it away via gravity using Newton Basedrain.

"The Newton waterproofing products provided an extremely straightforward and understandable system for keeping out the water. Furthermore, it was supplied with all of the required ancillaries and fittings that would be necessary, making it very easy to install, and providing me with total peace of mind that once in place, it would do the job." - Simon Williams, Director, Williams Creative Homes.

Finished to an incredible high standard by Williams Creative Homes, Simon has been living in the property ever since, whilst the Newton waterproofing system successfully ensures that his home is completely dry and protected.
