Event Details

Castle Drogo, designed by Lutyens for Julius Drewe founder of Home & Colonial, has leaked ever since it was built in 1910’s. Lutyens wanted cavity walls but the client was adamant that castles have solid walls. Drogo also has reinforced concrete roof slabs covered in asphalt which cracked and leaked.

Come and join us for a packed event including:

- A guided tour onto the roof where work is in progress
- A talk by the Project Manager and Q&A session
- A tour led by Alan Cook, setting the scene of how the building design changed as a result of WW1

This event counts as 2 hours CPD in conservation and contracts and includes refreshments.

For the energetic there is an excellent walk to Fingle Bridge if anyone wanted to round off their trip.

 

Location: Castle Drogo, Drewsteignton, near Exeter, Devon. EX6 6PB

PPE: Please wear suitable stout footwear and bring your own hi-viz vest and hard hat. You will be accessing high level externally on scaffolding. I highly recommend that you wear gloves and eyewear.

Time: 1.45pm latest for 2.00pm start

We will meet Alan Cook of the RIBA Exeter Branch at 1.30pm in the main car park, outside the visitor centre entrance, where you will be taken through registration.

Cost: £15.25 incl. Eventbrite fees, tour and entrance to the house and gardens. £5 to National Trust Members.

This event has been made possible by the support of the National Trust staff at Castle Drogo, site contractors and crafts persons, plus the generous additional financial sponsorship of the Branch by RIBA Local Initiative Funding

The group tours of the castle roof will allow a close up view of work, both completed and in progress.

 

 

At Castle Drogo the roof has never really been watertight since the castle was built by Sir Edwin Lutyens for grocery magnate Julius Drewe between 1910 and 1927. But then they do say that all great architecture leaks…

 

Following intermittent repairs over the years, the National Trust has a five-year project, with major support from the Heritage Lottery Fund, (£11M), to finally sort out the problems with the Drogo roof.

 

Castle Drogo’s medieval-style flat roof has been its Achilles heel. Lutyens had attempted to seal the roof using asphalt, a relatively new and untested material for the time, but it was prone to cracks caused as the temperature rose and fell. Before the building was even finished, it had begun to leak.

The windows have been another major weakness for Drogo. In keeping with a medieval fortress, Julius Drewe had demanded that there were no windowsills, a feature that would have offered some protection from the fierce elements. Every one of the 913 windows will be removed, refurbished and resealed.

 

A major part of the works is the huge and almost Piranesian temporary scaffold roof structure, erected to provide access and protection for the contractors.

 

Some facts:

  • A two-layer membrane designed by Bauder will be introduced to cope with the extreme temperature fluctuations and heavy rainfall of the Dartmoor area.
  • This will involve the removal and reinstatement of 2,355 separate granite blocks weighing 680 tonnes.
  • The high tech roof system (Bauder membrane) will finally make the roof watertight and eventually cover area equivalent to 2 football pitches.
  • 2,600 granite blocks will be removed and taken down to the ground.
  • Removal and repair of 913 brass framed windows.
  • Raking out and reporting 64km of mortar joints.
  • The total area of the temporary roofing is equivalent to 6 tennis courts, and the amount of poles amounts to 24,700.
