An education in old building repair

by Joanna Daykin

The SPAB repair course has been running since the 1950s with the aim to introduce the philosophy of conservative repair and specifically the SPAB approach to repairing old buildings, alongside the benefits of on-going repair to preserve the fabric of the building.

Two days of site visits are sandwiched between lecture days in Holborn. The first day focused on the principles and philosophy of repair and subsequent days looked at materials, structure and building elements. The great and the good of the SPAB shared their experiences and knowledge on each subject through case studies and pithy anecdotes which kept us all entertained as well as educating us.

The site visits helped to consolidate what we had been learning and provided an opportunity to discuss with other delegates about there work and experiences.

Wilton’s Music Hall

The first visit was to Wilton’s Music Hall in east London.  Five terraced houses built in the 1690’s were knocked together and the music hall built in their gardens in 1858. It’s glory faded as music halls went out of fashion after the Victorian era. The building was refashioned as a Methodist mission and later as a rag warehouse. By the 1970’s it was in a seriously dilapidated condition before what is now Wilton’s Music Hall Trust took the project on, fundraised and repaired the building. The current repairs, designed by Tim Ronalds Architects and undertake by the contractor William Anelay Ltd, have very gentle approach to conservation and are aiming to retain the magical atmosphere which makes it feel like one has stepped back in time.

The Temperate House at Kew Gardens

Opened in 1863, the Temperate House is the largest surviving Victorian glasshouse in the world. Since 2013, Kew has been undertaking a five-year restoration project on the Temperate House and its surrounding landscape. The works involve new services and plant installations (including a biomass boiler), cleaning and redecoration of the glass house structure and a new education programme to improve visitor engagement. The huge scale of the project is daunting and co-ordination of the building process around precious and rare plants makes it even more tricky. The project team includes; architects : Donald Insall Associates, contractor : ISG plc., engineers : Ramboll.

Manor Farm Barn, Frindsbury Extra nr Rochester
The barn was constructed as part of a wider monastic complex in 1403 to store tithes. It is believed to be the longest medieval timber-framed structure in Britain and is a very fine example of crown post trusses. The barn was subject to a number of arson attacks in 2003. The structure though badly charred and damaged, loosing a couple of end bays, was not destroyed. Now funding has been secured, temporary protection and urgent works are proposed to be followed up by more permanent repairs.

The local community will be included in the process and a number of apprentices will be taken on – teaching them timber framing using mediaeval techniques and tools. We discussed the merit of choosing to repair the barn in this way as opposed to using modern materials and techniques along with the decision to removed the charring from the existing beams. The opinions between members of the group were widely varied as each had a slightly different aspect which they valued most i.e. education in crafts, honesty in repair, good new design. It was interesting to hear no one opinion prevailing above the others and it will be fascinating to see how the repairs to the barn are undertaken by the heritage team.

Knole House

It’s quality Elizabethan and Stuart architecture is reflected in its lavish interior with ornate plaster ceilings, panelled walls and decorative joinery along with it precious collections. Originally an Archbishop’s palace, the house passed through royal hands to the Sackville family – Knole’s inhabitants from 1603 to today.

The National Trust is carrying out one of its largest repair programmes with the support of Heritage Lottery Funding. The work is being carried out in three phases over eight years. The first phase of  external repairs is complete. The next phase is to open a new Bookshop Café and visitor centre in 2015 and continue to build a world-class conservation studio in which will facilitate the final stage of repairs; conserving the showrooms and there artefacts.

The current phase of works by architects Rodney Melville and Partners has is being undertaken by contractors Fairhurst, Ward and Abbotts. The works have used utilised every type of repair philosophy to achieve an accessible and useful buildings to meet the needs of the house and the trust. This has sometimes been to minimise maintenance, improve sight lines or create more visitor friendly spaces.
