The guys from Channel 4 love a good oast cowl construction. Back in 2017 they featured us in their Village of the Year programme showcasing the history of oast cowls and Kent peg tiles. This time, they approached us to film the construction of an oast house a from start to finish. This is part of a programme that will showcase the build of different traditional buildings, each one being different and unique (a church, a windmill). With faces most definitely made for television, who were we to deny the public this experience?
They were particularly interested in watching us build the two oast house roundels (the roof) and the two oast cowls. As highly trained craftsmen and a fourth-generation family business, we know this process very well. We restore and rebuild oast houses and oast cowls from scratch and over the years, we have worked on all types of oast houses across the country, including buildings listed with local heritage departments.
Building an oast owl from scratch
We started the construction by pitching the two oast roofs known as roundels. We then used Tyvek (flash spun high-density polyethene fibres) to weather each kiln. After that, we used counter batten up each rafter, so that when we lathed the kiln it could hold the tile nails away from the Tyvek preventing holes. We then made onto the counter baton to work out where every row of tiles had to go so that they were evenly spread up the kiln and weathering one another.
Going onto the makes we added the lath, which is wood that’s run out really thin and therefore gives us an opportunity to bend it and pin it around the roof. The lath also serves as a base for the tiles. We used tapered and square tiles as due to their shape they’re able to go around the roof without running downhill. Once the tiles were on with lead and fibreglass, the top was ready for the oast cowl.
The last step of the process is to add the oast cowl on top, which we are in the process of putting on so watch this space for the final snaps!
