Marley Eternit tiles help cement vows at exclusive wedding venue

Architectural designers Chris Gothard Associates are extensive specifiers of Marley Eternit roofing products so they knew just where to look when it came to a vital stage in the ambitious redevelopment of a large Grade II listed country house They specified Marley Eternit's double-cambered Acme tiles in the colour Red Smooth for the re-roof of a Grade II listed carriage house and joiner's workshop that have been converted into a genuinely exclusive wedding venue and micro brewery respectively

Semi-fortified Thornbridge Hall near Bakewell in Derbyshire, which is originally Georgian but was substantially rebuilt during the Victorian and Edwardian periods, was bought by entrepreneurs Emma and Jim Harrison as a magnificent family home for their four children in May 2002 when they launched a programme of redevelopment under the auspices of Andromeda Park .

This has included converting the second floor of the building into bedrooms, converting the main hall into bedrooms and reception rooms, building a new winter garden room on the site of the former winter gardens, installing new services including a sewage treatment unit, restoring lodges on the estate for staff accommodation, and restoring gates and railings throughout the estate that features gardens that are listed Grade II on the English Heritage Register of Historic Parks and Gardens.

Located within Thornbridge Conservation Area, the hall is now a private residence although it was used for decades by Sheffield City Council as a residential training and conference centre.

Restoration was started by the previous owners and is being honoured at great expense by the Harrisons.

The roof of the Victorian carriage house was in urgent need of restoration and the original plan by Chris Gothard Associates, in conjunction with Martin-Brooks Roofing, was to reclaim as many as possible of the original hand-made clay plain tiles, some of which were believed to be Marley Eternit tiles, and use them on the external roof slopes, with imported reclaimed tiles on the internal slopes.

However, it soon became apparent it would be 'impossible' to source such a large number of tiles from one location and sourcing them from multiple locations would mean an "unsatisfactory" mix on single roof pitches.

In addition, it turned out that only a very small number of the existing tiles could be reclaimed so it would have meant mixing them with imported tiles on the same roof pitch which again would have been "unsatisfactory".

Not only that, after bats were discovered roosting in the roof space, DEFRA insisted all roofing works had to be carried out within a 10 to 12-week period and it would have been 'unachievable' to source, import, sort and fix all the tiles from all the different locations in such a short period.

Chris Gothard Associates asked planners at the Peak District National Park Authority to consider new 'handmade appearance' clay tiles which would "give a neater, more cohesive appearance" and allow them to complete the roofing contract within DEFRA's timescale.

Enclosing Marley Eternit samples for the authority's consideration, Chris Gothard Associates said: "A further benefit would be that the tiles would have a longer life span, with a guarantee of 100 years, meaning that maintenance and further necessary works to the building would be minimised.

Due to the large number of mature trees surrounding the building we feel the tiles would weather quickly and give a pleasing appearance within a short period of time".

The authority selected Marley Eternit's Acme Red Smooth plain and angular ridge tiles, which are guaranteed for 100 years, as replacements.

John Keeley, a planner in development control, said: "Whilst the Aylesham handcrafted tile has a good appearance, texture and colour, the drawback of its costs and to a lesser extent the single camber, are valid concerns which we have to take account of.

Although the decision was finely balanced, the Red Smooth was a close match which made it difficult to justify the extra expense of the Aylesham in this case".

Once the re-roof was complete, restoration by main contractor Baytree Interiors of the 12,000ft2 carriage house or stables block that had been used as dormitory and canteen accommodation by Sheffield City Council continued apace over seven months to provide a large, conservatory-style family/function room, staff/guest accommodation, basement bar and games area, catering-standard kitchen and toilets.

Chris Gothard Associates, who are currently working on an extensive indoor swimming pool complex and new tennis courts and pavilion in the grounds, met the brief to use traditional construction methods and materials to be sympathetic to the existing building and larger estate by 'detailed specification and traditional detailing to provide a cohesive exterior form appropriate to the historic setting, while giving a bright, modern internal atmosphere'.

Jason Bannister of Chris Gothard Associates said: "Materials specified were chosen to be the best of their respective kind in terms of appearance, performance and serviceability.

The Marley Eternit tiles provide a good match with the exiting, deteriorated roof covering, match with surrounding buildings, provide a roof covering which will weather quickly to reduce the initial impact of the new works, and provide an excellent finished result with good serviceability and extensive guarantees.

"Planners and local consultants such as the parish council and Victorian Society were fully supportive of the initial planning application and when visiting after completion of the works, were appreciative and impressed by the development.

The client is also absolutely delighted, costs not withstanding!".

Chris Gothard Associates specify Marley Eternit roofing materials such as natural clay plain tiles and fibre cement slates extensively for projects ranging from refurbishment of period properties to beach front cabins.

Jason added that the Acme tiles used at Thornbridge Hall "gave the appearance and performance characteristics required by such a prestige project and were aesthetically pleasing and appropriate for the setting".

Acme Red Smooth were also used on the roof and part walls of a former joiner's workshop that was converted into a private brewery near the carriage house. Request a free brochure from Marley Eternit ...
