The grade II* Listed Sacrewell Watermill has been restored and brought back to life, with the financial assistance of Heritage Lottery Funds and the William Scott Abbott Trust.   Part of Messenger Construction’s (conservation and restoration builders) remit was to improve the acoustic and thermal environment at Sacrewell, following designs by Purcell. The existing windows suffered from significant heat loss due to their age. A total of 8 units were fitted in various areas, bringing the spaces up to modern standards.  The windows were treated with a combination of Series 10 2-pane horizontal sliders and Series 10 3-pane horizontal centre sliders, set to match the original window’s sightlines.  The original plaster reveals were full of character; some were splayed and most were neither plumb nor true. Purpose made joinery grounds were produced and carefully installed to ensure the closest of fits was achieved with the secondary glazing. The restoration of this historically important building, which was on Historic Englands ‘At Risk’ register, has been a great success, with Sacrewell Watermill winning RICS East of England Project of the Year in 2016.
