HISTORIC ENGLAND LEAD BY EXAMPLE AND SPECIFY STELLA ROOFLIGHT AT YORK HEAD OFFICE

Historic England ( formerly known as English Heritage ) has specified and installed a Stella bespoke conservation rooflight at their York Head Office .
As part of a programme of works , which included several fire safety improvements throughout the building , Stella was approached by specialist heritage surveyors , Smith & Garratt to design a bespoke conservation rooflight . The design of which would need to provide suitable ventilation for the building ’ s communal stairwell .
Aside from the design functionality , the rooflight would also need to satisfy strict Conservation requirements , as the building is deemed of significant historic and architectural interest . As all Stella rooflights incorporate slender steel frames , which sit flush within the roofline , they were the ideal choice for maintaining the heritage of the building .
The Stella team worked closely with Smith & Garratt and specialist contractors CG Building & Restoration Ltd on an innovative design that would meet the approval of Historic England and the Planning committee . Stella Rooflight Director , Paul Trace , said : “ When Historic England approached us to help obtain planning permission , which had previously been rejected , for the refurbishment works at the head office , we were only too happy to help . We came
up with a unique rooflight design with electrically actuated central openings that would provide the solution they were looking for , while at the same time satisfying the planners .” The 2185mm ( w ) x 2050mm ( h ) rooflight consisted of four casements , of which , the two centre side hung opening panes are electronically operated by two pairs of high performance chain actuators and designed to open out 90 degrees to provide the required ventilation . The two remaining side panes were of a fixed design and were at the same level as the opening casements ; which was an important detail in satisfying the planning requirement .
As with all Stella rooflights the frame was manufactured using marine grade 316 stainless steel , with a C5 coastal powder coating to protect against rust and prolong the lifespan of the rooflight . A bespoke handmade hardwood liner provided a
stunning internal finish .
A high specification glazing consisted of a BioClean Natura Self-Clean and Solar Control outer pane with a black warm edge spacer ( Argon Gas ), and a Planitherm One Low E inner pane .
Due to the considerable size and weight of the rooflight , CG Building carefully craned the rooflights into position and fixed them into place , finishing the job using a pre-formed lead flashing kit provided by Stella Rooflight .
Historic England ’ s head office is situated at 37 Tanner Row in the Micklegate Ward of York city centre . The impressive five-storey , end-of-terrace red brick building is Grade II Listed and lies within a Conservation Area .
Originally built as a railway hotel in the 1850s , originally ‘ The George Hotel ’, latterly ‘ The North Eastern ’, the property today serves as the modern offices of Historic England – the Government body that
helps people care for and enjoy England ’ s historic environment .
