Having commenced my career as an apprentice joiner way back in 1986, I had always appreciated the historic built environment. During the long career that followed I was fortunate to work predominantly on historic buildings, manufacturing bespoke joinery products such as Georgian and Victorian shopfronts, period doors and entrances, boxframe windows and shutters, geometric timber staircases, and an eclectic mix of traditional period fitments for both domestic and commercial historic properties.

Despite having progressed to management, and having established my own successful manufacturing business, a passion for architectural design led me to change direction following the completion of a building surveying course. This was the first step towards becoming a Chartered Architectural Technologist and towards undertaking a qualification in Architectural Conservation. The MSc Architectural Conservation course at the University of Kent had appealed to me previously, as its flexible part time option would have allowed me to maintain my design and consultancy work. However, finding the right time to commit to two year part time study was constantly frustrated by work and personal commitments.

The 2020 Covid-19 Pandemic impacted hard on my business which resulted in an immediate downturn and left a void that would have been difficult to fill in the uncertain times that followed. Therefore, I took the decision to turn the negative into a positive and reverse the plan I had been considering by undertaking work on an enforced part time basis and to embark on study full time. This has turned out to be the best decision I have made throughout my long career and has already opened up doors to a new career path which compliments my existing skillset, and which will provide the practical experience to consolidate the theoretical knowledge the course provided.

Although I was confident in my abilities I had not undertaken academic studies for several years and this had been one of the hesitations that had prevented me taking the plunge previously. Having now completed the full time course I realise that these hesitations should not have been a barrier as the lecturers were understanding, supportive, extremely knowledgeable, and managed to push you out of your comfort zone to achieve results and realise potential. This said, the course is extremely comprehensive and demands a large degree of self-discipline and dedication to complete the four modules and dissertation successfully. However, the hard work is worth it as it is an extremely interesting and knowledgeable course which is accredited by the IHBC as meeting all recognised competences.

Modules on Heritage Legislation, Conservation Principles, Intervention, and Structural Appraisal provide a holistic understanding of architectural conservation which provided the theoretical knowledge to undertake the end of year dissertation. Having completed modules on the conservation areas of Herne Bay, Somerset House, Northgate, and St Andrew’s Chapel Boxley, I chose the Neo-Classical Clock House building at Ramsgate as my case study building for the dissertation. This proved to be an extremely enjoyable project, especially as I was encouraged to undertake a combination of a theoretical topic and a design proposal. The project used the Clock House building as it is currently on Historic England’s Heritage at Risk register and is in an area facing socioeconomic challenges. This provided an opportunity to analyse the effective use of Conservation Management Plans as well as developing the skills learnt through the course. This included historical research, how the building was designed and its development, site surveys and documentation, identifying levels of significance and mapping the buildings condition, preparing a statement of significance and discussing policies and strategies that would prevent further harm occurring and promote its significance and viable use to attract investors.

I would thoroughly recommend this course to anyone interested in architectural conservation or those who have an appreciation of the architectural form found within the historic built environment. It is a demanding course but the enjoyment offsets the hard work required, and I am sure you will not regret the decision to enrol!

The Society for the Protection of Ancient Buildings and St Andrew’s Chapel

 The Society for the Protection of Ancient Buildings (SPAB) purchased St Andrew’s Chapel in the winter of 2018, following its successful negotiations and proposals to rescue the Grade II* listed building which was in a derelict state and languishing on Historic England’s Heritage at Risk Register. This purchase has provided the SPAB with a perfect opportunity to promote their approach to conservation, which remains firmly based on the minimal intervention approach set out in William Morris’ inaugural manifesto of 1877. The building, which has witnessed many alterations and additions over its five centuries of history, has a wealth of evidential, historic, aesthetic, and communal significance. Despite its high intrinsic and extrinsic values, no-one could have predicted in 2018 just how valuable this building would prove to be as an educational resource following the 2021 Covid-19 lockdown.

The generosity the SPAB extended to the University of Kent included an introductory informative lecture, use of pre-existing laser scans, architectural drawings, photographs, and other associated documents of St Andrew’s Chapel. The information proved sufficient for decay mapping drawings to be produced of the exterior and interior of the building, as well as enabling three-dimensional axonometric drawings of the building to be produced. The wealth of available resources ensured that the Intervention at Historic Building module could go ahead as an entirely online solution to the problems created by the 2020 pandemic. Students embraced the situation and produced some extremely impressive work which included tracing the building’s history, mapping the building’s condition, documenting its significance, and proposing a sustainable new use for the building for both present and future generations. The SPAB were extremely impressed with the extent, variety, and quality of the work, when invited back to watch a number of presentations conducted by the students.

The proposals for new use of the building, which may well have been a fifteenth century Cistercian gatehouse chapel, provided a variety of ideas such as a gallery, museum, café, restaurant, wedding venue or a possible return to part-time residential use similar to the schemes offered by the Landmark Trust. All the presentations demonstrated a minimal intervention approach in order to protect the significance and setting of the Medieval chapel, as well as providing detailed theories on the building’s phased developments. Even though research in the building’s monastic and secular use proved to be inconclusive, the building is certainly worthy of its designation and will provide the SPAB with a valuable educational and heritage asset that present and future generations will benefit from.

St. Andrews Chapel, Intervention Proposal

This year’s module ‘Intervention at Historic Buildings’ was delivered in collaboration with the Society for the Protection of Ancient Buildings (SPAB), and gave the students the opportunity to develop a conservation plan for St. Andrews Chapel in Maidstone. To help the students document the building, the SPAB generously provided access to its laser scanning survey of the building. Shown here, this model became the basis for this year’s student projects.

This survey technique produces models that provide considerable information about historic buildings and their condition.

This model constitutes an invaluable record of the buildings current condition and makes it possible to investigate the cause of its decay.

The south elevation of the Chapel present us with a ‘palimpsest’ of different phases. One of the students’ tasks was to retrace these phases and propose their own interpretations of the history of the building and its transformations through time.

Laser scanning models can form the basis for accurate depiction of historic buildings in plan. They also help to document the buildings’ interior.

When I joined the MSc course of Architectural Conservation at the University of Kent, I didn’t know much about British heritage and practice. Driven by my passion for historic sites, I came to discover astonishing architectural styles and historic preservation practices and philosophies. The ‘Conservation Principles’ module confronted me with some tricky questions. Should a historic building be saved partially or totally? Why do we care about its preservation? When was the building destroyed and what has been lost? How should we preserve? I soon realised that answers based only on personal views and culture can be biased… Only by studying the cultural, geographical, socio-economic and political context of a historic building can we really understand its significance and proceed to restoration.

There are different attitudes to conservation. It was fascinating to compare philosophies as different as those of Violet le Duc, John Ruskin, Cesare Brandi, and Camillo Boito, as well as conservation charters such as those of Venice and Athens. In addition to conservation philosophy, the programme introduced us to historical societies, charities, trusts, funding bodies and community involvement regarding heritage. I realised that besides understanding the UK planning system, one should be familiar with the work of amenity societies and funding bodies. After all, successful historic preservation in the UK lies in the combination of a robust legislation with the work of societies such as the Society for the Protection of Ancient Buildings (SPAB) and the Victorian society, organisations such as English Heritage, and funding bodies such as the Heritage Lottery Fund.

After this initial focus on policies, laws and philosophies, it was time for action… I was very excited to hear that the Spring Term module ‘Intervention at Historic Sites’ (January through April) would be delivered in collaboration with the SPAB and would be based on the Society’s ‘Old House Project’, the preservation of St. Andrew’s Chapel, near Maidstone. Alas, I missed the first guided visit to the chapel. Visiting it a few days later with a classmate was one of most exciting moments of the programme. This was a unique chance to experience an unspoiled medieval building, which is very little known. Formerly part of the Cistercian Boxley Abbey, the chapel was converted into a dwelling in the 16^th century. Abandoned for decades, the chapel is now in an advanced state of decay, but is not entirely derelict. Some of its features, such as the late-Gothic mullioned window, the Tudor chimneys, the post-dissolution half-timbered extension, and the early 20th-century fireplaces survive and reveal the complex history of the building.

Drawing the chapel, looking at its decay, retracing its history, and reflecting on repair methods was rewarding, and designing a proposal of adaptive reuse added to the pleasure… Here are some samples of my analysis of the decay of the chapel:

I look forward to visiting the site again, to take a long walk through the narrow pilgrims’ way near All Saint’s Church. I will then follow Boarley Lane from which I can enjoy the scenery around Boxley Abbey’s gate. I will admire the mysterious remains of the Cistercian monastery, particularly its medieval Barn. After another visit of the monastery garden, I will return to Boarley Lane and St Andrew’s Chapel, which lies just before the motorway, waiting for its repair.

Recently, the students of the MSc in Architectural Conservation visited Canterbury Cathedral. Our student, Chandler Hamilton writes: We had the chance to tour the sections of the Cathedral that are under repair. All these areas are normally unavailable to the public. I focused on Gothic Architecture in my undergraduate degree, and for me, this was a unique opportunity to get a behind-the-scenes tour of a structure that I have studied intensely in the past. The tour started off with meeting the Head of Conservation and Site Manager, Heather Newton, who basically has my dream job! She gave us an introduction to the conservation project and an itinerary for the day. The project that started in 2016 and is set to finish around October 2021 is a 25-million-pound development that is focusing on the roof of the cathedral.

We went all the way up to the top of the scaffolding on the western towers and saw a breath-taking view of the roof and the city of Canterbury. At the top you can see the difference in each piece of stone by how eroded it is. Since the cathedral was first developed, stone has been replaced throughout each century. One interesting fact that I did not know was that in the early-20^th century, there was a shortage of materials and funding, so the builders created stone-like blocks out of cement instead. There is a course on the northern side of the cathedral where you can visibly see the cement.

We then moved down into the top of the nave where they are currently repainting the ribbed vaults and sealing off cracks. Not only was this the closest I have ever been to ribbed vaults and could clearly see every detail, but there was also an incredible view of the choir to look out to.

The last stop on this tour was the inside of the roof to look at the timber structures that are supporting the buttresses. Each piece of timber is extensively investigated for any signs of decay, rot, or damage, then decided on if it needs to be replaced or not. They are trying to preserve as much of the Victorian wood as possible, so they only replaced the end where two pieces connect.

That Canterbury Cathedral constitutes a fine example of Gothic and Romanesque architecture is widely known. What few people know is that this same building has been restored and partly rebuilt countless times, and, as a result, exemplifies various attitudes to conservation. In our last visit to this monument, we were accompanied by the head of Stone Conservation at the Cathedral, Ms. Heather Newton. Ms. Newton gave us a rare opportunity to explore “the unseen world” of the roof and the tallest tower, Bell Harry. The roof, mostly dating back to the Tudor period, has been divided to several rooms for fire protection. Its beams have been restored numerous times following the rotting of the original timbers. Circulation inside the roof was through a series of timber corridors, which offered access to the ceiling without loading the nave vaults below them.

The most challenging part of our visit was the ascent to the top of Bell Harry, the tower over the crossing. On the base of the tower, we found a sophisticated crack monitoring gauge and a humidity meter that records the micro-climate of the cathedral’s interior. After hundreds of steps, we reached a room where we found the pulley mechanism for the lifting of building materials. On the top of the tower, apart from the old bell mechanism, there is a microscopic meteorological station which is linked to a central computer inside the Cathedral. The highest point of the cathedral is exposed to the weather, and this has caused the decay of the limestone there. Unfortunately, as Ms. Newton explained,this decay seems to have been accelerated by “plastic repairs” carried out in the 1930s. These involved the use of cement mortar to fill cracks and to recapture the lost profiles of stone elements. This hard, impermeable mortar prevents the “breathing” of the wall and the evaporation of moisture. Trapped in the core of the wall, moisture accelerates stone decay caused by frost weathering and the crystallization of salts.

On Monday, we attended a lecture on the Roman Forum by Professor David Watkin, one of the most important historians of our times. The “Foro Romano”, visited by millions every year, has had a fascinating and vivid building history from Antiquity to the Present. During this period, the forum was repeatedly modified, and as a result, distinguishing the dates of its buildings is not always easy. Temples that seem to be ancient were in fact erected just eighty years ago. For instance, the Temple of Vesta, in its present form, dates back to the 1930s (Watkin David, The Roman Forum, p.16).

Examining views of the forum, including the famous ones engraved by Piranesi, Watkin revealed the Roman monuments in all their grace and splendour, and traced their development from the Early Cristian Times to the Baroque period. The way in which churches were integrated into old roman edifices was absolutely astonishing. On the other hand, the Nineteenth Century idealized the “magnificent Roman ruins” at the expense of more recent buildings.

After a visit to the Forum it is easy to feel disorientated as you are trying to resolve a puzzle of multiple building phases that make the monuments comparable to palimpsests. Despite the archaeologists’ recent interventions to the site (considered to be “clumsy” by Watkin), the Roman Forum remains an ideal site to study Rome’s history and architecture as well as the development of conservation philosophy.

The new MSc in Architectural Conservation has started with a site visit to the historic centre of Canterbury, followed by lectures and seminars on Conservation Philosophy and Policy. The lecturers in the first term include Dr. Manolo Guerci, Dr Nikolaos Karydis, and Dr Timothy Brittain-Catlin. We have also enjoyed three guest lectures by Martin McKay, Conservation Officer, Medway City Council, who illustrated his lectures with many interesting examples from Medway. We very much look forward to the lectures of Prof. David Watkin and Nick Dermott (Conservation Officer, Margate Council) next week.
