From pallets to shed

11 April, 201220 August, 2012 Juliet Kemp

I spent much of February slowly constructing a shed (more of a tool cupboard, really; our garden is very small) from deconstructed pallets.

The first step was to measure up (my shed was 80cm x 60cm in footprint, and spade-height-plus-a-bit in height) and cut the pallet planks to size. I think I used about 2.5 pallets, and a hand-held circular saw (very very useful to speed things up).

I also needed four lengths of 2×2, one per corner, to attach the planks to. My design called for a sloping roof (so the rain runs off), so required two shorter lengths for the back, and two longer for the front. I nailed the back planks to the shorter lengths, and each set of side planks to one of the longer lengths (so at this point the side planks were braced only at one end).

The back wall, screwed into its 2×2 bracing at both ends of the planks.

One of the sides, with only one end braced. Note that its 2×2 rises above the planks; this is because it needed a triangular piece of planking attached later to allow for the slope of the roof.

The next step was to screw the loose ends of each side piece to the 2×2 bracing of the back piece.

Shed with three sides. Note again the space at the top of each side for a triangular piece. (Apologies for the sun flare in the photo!)

Shed corners screwed together.

I measured, cut, and attached triangular pieces for the top of each side (no photos, sorry). For the roof, I cut a piece of plywood which overlapped the sides by about 4-5cm in each direction. I intended to cover this with some thick black plastic left behind by our kitchen fitters, but my Dad came up instead with a roll of roof felt from in his garage, so I was able to do a more professional-looking (and longer-lasting!) job with that, roofing glue, and some roofing nails. Before covering the roof, I screwed in a batten at the back to keep it from sliding off.

The batten on the underside of the roof, and the roofing nails keeping the felt down. The felt was glued down on the topside of the roof.

Since installation, I’ve added a couple of battens at the front to keep it square and to brace the roof.

It still lacks a door (I’m on the look out for some large enough plywood), and at some point I will use a couple of L-shaped metal bits to attach the roof, rather than using bricks to hold it down. But as of now, it does the required job, and, given the high percentage of reused materials, for minimal financial or environmental cost. I’m also kind of proud that I built it at 38 weeks pregnant!

Making things

3 April, 20123 April, 2012 Juliet Kemp

Recently, I have been making things:

The second one took a bit longer, and is kind of still under construction.

Actually the shed is also still under construction, lacking as it does a door; it has however had front battens added since that picture. Construction post to follow. I’ve also got going with this spring’s planting in the raised beds over the last month — more to follow on that as well.

Making raised beds from pallets

4 January, 201220 August, 2012 Juliet Kemp

Last week I made a fourth raised bed for the garden; like the previous 3, the wood came from a couple of deconstructed pallets rescued from a nearby skip. It took me just over an hour (with power tools: a hand-held circular saw and a drill with screwdriver fitting; add about another 30-60 min if using hand tools), which did not include the time to deconstruct the pallets. Here’s how I went about it (apologies for the lack of as-you-go photos; I wasn’t thinking of blogging it at the time!).

Another of my raised beds, with some broad beans growing in one side. (The other side needs some more compost…)

The basic construction is 3 pallet-planks per side (for a total of 12 needed), cut to the size needed (in my case, 3 paving slab widths on the long sides and 2 on the short, to fit the intended gap). Measure up your planks, and cut them to size.

Long side of raised bed (once complete); 3 135cm planks.

Short side of raised bed (once complete); 3 90cm planks.

The next step is to attach everything together. It’s possible just to nail/screw the planks directly to one another at the corners, but that won’t be very stable. A better bet is to use a thicker piece of wood as a brace at each corner, and screw the planks to that. Happily, pallets are constructed with a couple of nice thick ribs down their middles which are ideal for this. Cut 4 corner braces from this. The length of each brace should match the width of 3 planks, so that it’s the same height as the plank-sides of your raised bed.

Take the first set of three long planks, and two of the corner braces, and screw the planks to the braces at each end. Repeat with the other set of long planks and the other two corner braces. You now have two long sides of a rectangle, each held together by the braces, but not attached to each other.

The bracing piece, shown from the inside (with both long and short sides attached).

Now screw the two sets of three shorter planks into the braces at each end, to make the short sides of the rectangle.

From the outside, planks on two sides screwed to the brace. As a rule, the long and short sides should be the same height, but my planks were slightly different widths and that didn’t quite work out. Aesthetically suboptimal but still perfectly functional!

That’s it! These should be pretty sturdy, especially once filled with soil to strengthen them. You can rest them on existing soil (in my case, where I’ve levered up the paving slabs from the garden), or, if you make them slightly deeper, you can put them straight onto concrete, put cardboard at the bottom and shovel compost in at the top, and treat them as a very large container.

Note on tools and fixings:

You can do all of this with a hand saw, and I have done in the past, but a hand-held circular saw makes it all a lot quicker (and in my case, at 7 months pregnant, makes it feasible; I’d have struggled to construct this on my own by hand).
Nails can substitute for screws, but they won’t be as secure.
Whatever the packet may say, screws go in quicker and easier if you drill pilot holes first. The screwdriver fitting on a power drill is also a godsend, but again, hand tools do the job, just a little slower.
A set-square is useful to get the cut lines straight. If you don’t have a set square, all hand saws have a right-angle marker and a 45 degree marker on the handle.

Poly-veg winter bed: update

25 November, 2011 Juliet Kemp

With the single currently-active raised bed in the back garden, I experimented with a winter polyculture, or mixed-veg bed. It’s now looking very healthy, with plants in various stages of growth:

Some garlic poking its head up, all around the edge of the bed. Garlic is often a good choice for edging beds, as it’ll help to keep off pests (when they return in the spring). I didn’t get around to getting a decent bulb of garlic from a proper shop, so I just stuck in cloves from a bulb from the Co-op. I wouldn’t want to save any cloves for next year from this crop (since I know nothing about its parentage), but it was a quick and easy solution.
A row of winter lettuce seedlings at the back of the bed.
Some very healthy-looking broccoli raab and turnips (although the turnips themselves are not up to that much; I will use the greens as well when I pull them up, to make the most of the crop).
A couple of small chard plants.
You may also spot a fair few small rocket plants scattered around the bed. I had lots of rocket seed so scattered it widely. It needs some fairly aggressive thinning, as it’s over-thick, but it’s very tasty so this isn’t a hardship. Having the soil covered thickly like this with plants I do want reduces the number of plants I don’t want (weeds) which can make their way in.

In addition to that lot, there’s a few snow peas and broad beans that aren’t quite up yet, planted where there were some bare patches towards the back of the bed. Looking for bare patches as the crops start to come up, and taking advantage of them, is another principle of polycultures and forest gardening type approaches.

I’ve also constructed another couple of raised beds (one has some broad beans in, but neither are full of compost yet), and transplanted the rosemary to its new home against the fence. The soil here is not great for a Mediterranean herb like rosemary; it’s very clay-heavy, and not well-drained. To give the plant the best chance, we dug a biggish hole and dug in some compost and sharp sand at the bottom of it and around the plant. It’s a sturdy plant (and was badly outgrowing its pot), so hopefully it’ll survive the winter and get going again in the spring. The cuttings that I took (in case it does turn up its roots and die) seem to be doing well so far.

For the end of November, it’s all looking pleasingly green; and I’m still getting regular (albeit small) crops of greens from it.

Cargo bikes, fracking, and raspberries

8 November, 2011 Juliet Kemp

I have been writing things in other places!

UK Activists Tell Energy Companies To Frack Off.

Kids and cargo bikes. (Since writing that, we’ve decided to go ahead and get the Christiania trike. I am inordinately excited, though we won’t be ordering it for a month or so.)

In ‘garden’ news, yesterday I transplanted 6 raspberry suckers (4 autumn raspberries, 2 summer raspberries) from the allotment to the western garden fence. I’m unsure how they’ll get on with the clay (I dug in a little sand and compost), but as otherwise the suckers would have been snipped up and put in the compost, it’s worth the experiment.

The Garden Project: quick-win vegetables

9 October, 2011 Juliet Kemp

So, we planted one side of our new garden with grass already. On the other side (the eastern, and thus west-facing, side), the first quick win was to move the pots of tomatoes and herbs from the old balcony. The west-facing fence was ideal for tying up the tomatoes, and it immediately made the space look more garden-like.

My parents also brought along four or five large polystyrene tubs (from frozen food deliveries) and some bags of compost, so I used those to plant a few turnips and some rocket and mustard greens, all of which do well in late summer. Another good quick win.

My intention is to construct a bunch of raised beds, as the ground underneath the paving slabs is compacted London clay, which hasn’t been cultivated at all for at least a century or so.[0] Instead of trying to improve it enough to grow directly in it, it’s easier to put compost on top and let the soil underneath improve gradually. (It’s also safer, as we don’t know what the ground might be contaminated with, other than certainly lead, like any other patch of inner-city ground.) However, I want to think about the placement of these for a bit, and observe the flows (of sun and frost) in the space, before I do anything too much.

I decided that a single raised bed would be OK: at worst, it would be manageable enough to dump all the soil out of it next spring and relocate it. So I turned a deconstructed pallet into one raised bed, and took out the paving slabs and weed matting under that area. That left me with about an inch of sand, and compacted London clay underneath. I stuck a fork into it all a few times, then dumped some half-rotted leaves and about 100l of old compost/new compost/’soil improver’ (cheap from the Southwark waste recycling centre) on the top of it.

In deciding what to plant, I took the polyculture annual veg approach I learnt in a session on the EAT course. There’s a limit to what will do well planted in late summer, but I started off with a few kale and broccoli raab plants, which by now have a few small edible leaves. A couple of weeks later, I planted a few transplanted turnips (success: middling), some chard, and a lot of rocket and other mixed greens. The salad seedlings are coming up well now, and in a week or so I’ll be able to harvest the first baby chard leaves.

In late September, I planted a row of spring cabbage towards the back of the bed — it may be too late for these to do well, but we’ll see; I might get lucky with the weather. Later this month I’ll plant some garlic around the edges (good for keeping the pests off), and in November, some broad beans wherever there’s a bit of space.

It was definitely worth the effort – even if I end up having to move it in the spring – to have that bed already in place and seedlings growing for the winter. It feels something like a proof-of-concept, or perhaps just a promise to myself that there will be a lot more of these by this time next year.

[0] The house was built in the mid-1990s, on land that used to be occupied by a warehouse, which was there from at least the early 20th century; we’re not sure exactly when it was knocked down, but at best the land will have just been derelict for a bit before the estate was built. Prior to the warehouse, there was either housing, or possibly boat-building, going on in the area.

The Garden Project: creating grass

8 October, 20118 October, 2011 Juliet Kemp

Along with my recently-moved-into new house came a new garden. Specifically, a south-facing space about 8m long by 5m wide (tiny by most people’s standards; pretty decent by local standards; and a huge improvement on the 5m x 1.5m balcony of our previous house). As of our moving-in date, it was entirely paved over, with a single and somewhat overgrown dog rose at the southern, shadiest end.

My overall intention is to spend a few months thinking, from a permaculture perspective, about a proper plan, and start to implement that in the spring. Indeed, ideally I’d wait a whole year before doing anything, but I think by the spring I should have enough information to get going.

However, there were a couple of more urgent issues:

We wanted a patch of grass for the dog more or less immediately.
I wanted some kind of plant-related quick win, to make it more like a garden and less like a very large pavement.

For the grass, then, we went for the quick-and-dirty decision-making process, which looked a bit like this:

There’s a patio at the house (north) end, which is solid concrete masquerading as railway sleepers(!). Doing anything with that will be time-consuming and expensive, so for now it stays. So no grass there, leaving the rest of the garden to be considered.
We wanted the grass to be accessible directly from the patio, so that it’s useful for humans to meander over and sit on, and so that the dog wouldn’t have to wend her way through the vegetable-growing part of the garden to have a pee. Given the north-south orientation of the garden, that meant a north-south strip.
There’s an old gardener’s maxim “west is best”; so I wanted to hang onto the west-facing side of the garden for the veggies.

By process of elimination, we wound up with the east-facing side (the western side) of the garden for the grass.

We started off with a test patch at the bottom of the garden. Unfortunately it turned out that under the ‘easy to lever up’ paving slabs, in a couple of places there were ‘much harder to lever up, and bloody heavy’ concrete slabs. Underneath that was an inch or so of sand, and underneath that, a layer of weed matting. (Under that, highly compacted clay, as one would expect in London.) P succeeded in getting up all the slabs and concrete on the test patch, and ripped up the weed matting. Since grass doesn’t like too rich a soil, we mixed in a lot of old compost with the sand, and dumped some grass and wildflower seed on top of it to see what would happen.

Answer: glorious green success.

This week, D took up the rest of the slabs on that side, forked over the sand and clay and spread a light layer of compost, and we spread more grass and wildflowers over the lot. Hopefully we’ll have at least a little greenery there before the winter sets in properly.

In the next post: pots and a raised bed, for late summer and winter vegetables. (Hopefully also I’ll have added some photos to this post by then.)

One change at a time: easy shower greywater reuse

7 October, 2011 Juliet Kemp

After a very full-on fortnight learning about permaculture and activism at the Earth Activist Training 2011 course in August, I came away all fired up to make some changes at home. I would absolutely love to set up some kind of greywater reuse system, but given the 40 sq m of garden available in my central London terrace, it would be both a big practical challenge and a pretty poor use of our limited outside space.

However! There is a very straightforward way to reuse some of your greywater, which requires only a bucket. Put the bucket in the shower, where it can catch some of the water you use while you’re showering. The next time you need to flush the loo, grab the bucket and pour it down there instead of hitting the flush. There you go: a bucket of water saved per day, with next to no effort.

I started doing this a couple of weeks ago, and can definitely recommend it: both easy to implement and personally satisfying (if you’re the sort of person who gets satisfaction from saving water). Sure, it’s not a huge amount; but it’s more than nothing. Not only that, but I’ve found myself more aware of the water I’m using whilst showering (and have taken, for example, to turning the pressure down a bit), which is a neat secondary advantage.

Watch this space for more on my permaculture adventures; specifically the plans for the brand-new garden, and my solution to maintaining the allotment next year on what will be a very small amount of available time.
