Elkstone Church Compost Toilet

Recently I was privileged to work on a monumental compost toilet with master timber framer Jim Symon. This toilet was commissioned for the grounds of a Norman church in Elkstone. Many churches are without toilet facilities, and as installing mains services to an Ancient building surrounded by graves is both impractical and inappropriate, compost toilets are a great option. In fact, in my opinion, compost toilets are generally the superior option. Using water that has been made fit for drinking, to transport this potentially useful resource away for arduous treatment, is an illogical activity. I stumbled upon some advice given to farmers by the Board of Agriculture in 1804, which encouraged them to build houses for their workers, because, "a ready supply of labourers is not the only advantage a farmer may reap from cottages. He will have, at an easy rate, all the manure they can make....". I think both the building of rural housing for workers and the use of human manure for fertiliser are pieces of advice that we'd do well to heed today. 

Jim Symon's compost toilet creation is a wonderful example of how a loo can be a beautiful feature that fits well into its surroundings. The frame, cladding, flooring and rafters are all local Oak, with sawn local Cedar shingles.

Compost Toilets

The last month has been dominated by compost toilet builds. Two of them I have designed and built myself using timber from our sawmill and the third was largely the creation of Jim Symon, an excellent timber framer. This latter one was build using Oak and was in the grounds of a Norman church. I currently have no pictures of this one and will endeavour to return and snap some.

This toilet is a twin vault system, so it has two wooden chambers, each with a separate lid. Only one of these gets used at a time and when the chamber is full, the lid gets screwed down and it is left to compost for two years. Meanwhile the second chamber is being used.

Urine goes straight into the chamber with the faeces where it is absorbed and composted by added plenty of dry, carbon rich matter, in this case this is coarse sawdust.

The structural timbers, cladding and steps are Larch from our sawmill. The floorboards and exterior of the door are reclaimed Larch tongue and groove. The interior of the door is our own flamed Beech, laid diagonally and the toilet seat is spalted Sycamore that I milled 3 years ago.

The steps were based on an Oak staircase that I saw in an old building at the Weald and Downland museum. The door handle with suffolk latch and bolt are hand carved from Elm and Ash.

The second toilet uses Larch throughout except for the seat which was from a large Ash tree that I milled after it fell during a landslide. This toilet uses wheely bins as it is for a glamping site which will produce an unknown amount of waste and therefore as many bins as necessary can be used. There is a urine separator which diverts it into a separate chamber.

Roundwood Roundhouse Roofing Revisited

I've been going through some pictures on my camera that I never uploaded onto my computer and found some further photos of the roundwood roundhouse we built 2 summers ago.

Pickup Truck Camper Shell work in progress

In between my current run of building a plethora of compost toilets I am working on building myself a camper canopy for my pickup truck. This is a bit more of a conventional carpentry project than my usual fair, in that I'm using glue and screws to join it all together and cladding it externally in thin marine ply to keep the weight down.

The main frame is made from 2"x2" Larch that I milled a while ago and stacked to season and the roof ribs are cut from 1" thick Ash.

I struggled with the idea that the whole thing would be clad in soulless, bought in plywood, considering that I co-own a sawmill and mill up lots of beautiful homegrown timber. So (with some slight worries about weight) I have decided to clad it internally with some incredible spalted Beech boards that I had milled to 8mm thick for another project.

I am hoping that the canopy will be removable with 4 people when all the cladding and insulation is installed, but we shall see....

The current plan is to roof it with Aluminium sheet and to try my hand at some traditional style sign writing on the plywood sides.
