Study the technical and practical skills relevant to the repair and maintenance of historic buildings and structures. Improve your skills and up-to-date knowledge of developments in materials, techniques and current practice.

The Professional Development Diploma is recognised by Historic England and adheres to its guidelines and standards aimed at improving building conservation practice. The Historic England Practical Building Conservation volumes are the core texts which underpin the courses. The diploma is designed and delivered by leading practitioners and follows the latest knowledge and developments in technology, craft and science applicable to historic buildings, archaeological sites and monuments.

The unique Ruinette at West Dean, on which students practise conservation and repair techniques, is a purpose-built structure exhibiting the materials and defects typically found in historic buildings. The diploma is aimed at those who need to develop practical skills and those who need to understand, specify and supervise them.

This historic building course is ideal for conservators, conservation officers, architects, surveyors, craftspeople and specialist contractors.

Student perspective

"I've been project managing a Heritage Lottery Funded Skills for the Future project, to support traditional building skills training and address the shortage of skilled craftspeople in and around Leeds. The city has a huge number of buildings built before 1919 but diminishing numbers of specialist heritage construction workers.

I'm looking to continue working in this area. I have an understanding of building conservation but wanted some practical training, this seemed to be the most practical course available and was recommended by a colleague. The ability to study towards accreditation in short bursts also suited me and I'm very grateful to have been awarded a bursary by the Drake Trust to enable me to study here.

The standard of tutors and speakers has been superb … it's been a privilege to study with them. I've also met a range of contacts who I know will be useful for future networking. Because of the highly respected nature of the courses here, I've been asked by colleagues to report on some of the expertise on my return, up-to-date developments in the use of lime mortar for example.

Overall, I've found the courses to be an excellent mix of practical and theoretical learning supported by great facilities."

What level of qualification is the diploma?

The West Dean Professional Development Diploma certificate is equivalent to Level 4-5.

Does blended learning mean I can study theory at home in my own time?

Yes – there are currently four courses being piloted in e-blended format with the likelihood that more will be offered.

How many hours of self-study are required per Building Conservation Masterclass (BCM)?

We estimate between 10-12 hours are required ahead of each practical session. The online elements are started 3-4 weeks ahead of the practical with some ‘live’ Zoom group discussions to allow tutors and students to meet each other ‘virtually’ to prepare for the practical.

How much hands on practical training is there per BCM?

This varies per course. Typically, two days focused practical work per BCM. 

What is the average time taken to complete the diploma?

There isn’t an average as it depends on working commitments. Some students choose to do the BCM courses back-to-back, others spread them out. Applicants have up to five years to complete the course.

Is there funding available for this course?

The Drake Trust provides bursaries to support this Professional Development Diploma. Please contact us at [email protected] to apply for this.

Do I pay my fees upfront?

You pay for each course as you book. So you pay in increments with a £450 registration fee.
