Towards the end of 2014, Steven Roberts contacted us with regard to an old windmill that he planned to renovate and use as a holiday let. Originally built in 1891, the windmill was in a state of disrepair and required an extensive programme of renovation which included an insulated render system.

Permarock’s insulated render system was selected and InBuild was appointed to carry out the work. There were many challenges along the way, primarily due to the fact that every surface of the building is curved. Rockwool was used to insulate the exterior walls because it has a degree of flexibility, and it was cut into thin strips 200m wide to accommodate the curves. The 200mm thick insulation was fitted with both adhesive and mechanical fixings and this was followed by mesh and a render base coat.

In order to achieve a smooth, continuous surface with no movement joints, the top coat had to be applied in one day; this meant having 16 renderers across the various levels of scaffold, all right-handed to achieve the same pattern. The resulting black render finish is both striking and practical and will require little or no maintenance.

After months of careful renovation, The Windmill Suffolk is now ready to open its doors as a contemporary country hideaway. Situated between Bury St Edmunds and Sudbury and around 2 miles from historic Lavenham, the Windmill boasts panoramic views across the rolling Suffolk countryside. The luxurious interior is complemented by a ‘POD’ and balcony on the 4th floor to make the most of the stunning views.
