Are you thinking of buying a new garden shed?

Is your current garden shed looking tatty? Do you need more garden shed storage?

Essential info if you're trying to decide whether to repair your shed or buy a new one. #shedproject #sheds

We’ve been pondering these questions for the last ten months. I dithered and googled, quizzing friends and experts about their garden sheds.

So I’ve found out some things that surprised me. I’m going to pass them onto you before you waste money on a garden shed that isn’t right for you, doesn’t last or costs much more than it should.

And you may find it cheaper to update your current garden shed. There are some interesting shed upcycling ideas in Don’t Hide An Ugly Shed! Make it Look Beautiful.

1) Garden sheds are portable

Obviously, you can’t pop one in your suitcase and take it away with you for the weekend. But if your garden shed is in the wrong place, you may not need to buy a new one. You may find it cheaper simply to move it.

We had a small shed and needed more storage space. Before our landscapers installed the new shed, they moved the old shed onto the terrace, so that we could continue to use it for storage until the new one was ready.

How to move a garden shed

Hup, one, two, three…our little old garden shed is picked up by strong men…

It’s quite a small shed and took two strong men, so this isn’t a trivial job. But it’s probably cheaper than buying a new shed.

Moving your shed may be better than buying a new one

The garden shed sets off on its travels across the terrace.

The shed sat outside the back door, looking disconsolate, but offering useful storage.

2)The most important thing about a garden shed is its base

We spent hours on the internet and in shed stores, trying to decide on the style of our new shed.

However, we barely gave a thought to the base. Many people just opt for the cheapest. It’s an extra tick on an online form.

Some people don’t bother with a base at all. But if you have a poor quality base or no base at all, the shed will absorb water from the ground. It’ll rot quickly.

And a slightly uneven base puts pressure on the construction of your shed. A shed set on paving stones or gravel may sink and become uneven over time.

There is no point in wasting money on a good quality structure if you’re going to expose it to damp and rot from the base upwards.

Doesn’t the base come with the shed?

If you buy your shed from a shed company, you will be offered a separate base, usually a wooden grid. It’ll add to the cost (starting from around £100).

Wooden grids will protect your shed by lifting it off the ground, but they will rot themselves over time. Ready-made sheds all usually come with floors, but that’s not the same as the base. The base is what the shed sits on.

You can have a paved, gravel or concrete base, too. After talking to shed experts, I have concluded that a concrete base, professionally laid, is probably the best base for a shed.

So we got a concrete base laid first, with one course of bricks on which the shed could sit.

That’s why we had to move the old shed out of the way. We couldn’t get rid of it immediately because we still needed somewhere to store the garden chairs while the concrete was setting.

3) And the roof is pretty important too…

I spent hours thinking about the design, the windows, the door, the shelving and the colour of our new shed. I gave very little thought to the roof.

If I’d never owned a shed before, I think I would just have chosen the cheapest roofing felt. But when we bought this house, the garden sheds were already there.

Shed roofing tip

My potting shed. It looks OK from a distance, but the roofing felt won’t remain on, so the wood is rotting.

The potting shed and the terrace shed both had roofing felt. We have had endless trouble with it. It curled off. We nailed it down again. The wind ripped it off. We even got a new piece of roofing felt. That didn’t last.

The roof was so leaky that I didn’t have to water the plants inside when it rained.

We got quotes to replace the whole potting shed roof. They varied from £350 to £850.

Should you buy a new shed or repair the old one?

I could buy an entirely new potting shed for around £750. It seemed madness to spend hundreds of pounds restoring an old shed when we could buy a new one for not much more.

We didn’t want to spend hundreds of pounds on a twenty-year old shed, but why spend more to replace it, if it doesn’t need replacing?

When you buy a ready-made shed, the roof  is often extra to the list price. There is a board roof supplied, which will be fine for a few years. If you want more protection, there is usually a roofing felt option. It will add around £50 to the bill.

However, we never want to see roofing felt again.

Eventually, we took one of the lower quotes (around £350) to replace the potting shed roof with a rubber membrane roof. It’s slightly more expensive than roofing felt, but should last longer. The old roof was cut away and the new roof brought in as a single unit and put on top like a lid.

Replacing a shed roof

The roof coming in. It was put on the shed like a lid.

Now that there is a new roof on the potting shed, it is dry and sound. I’m very glad I didn’t replace it.

4) A little extra internal space can make a very big difference

With so many good ready-made sheds on the market, is it worth spending a few hundred pounds extra on having a shed built for you, in exactly the right size and shape?

Our original terrace shed was 6ft x 4ft. It was crammed to bursting with deck chairs and the barbecue. We couldn’t even get in there to keep things tidy.

Small storage shed

This shed measures 6ft x 4ft and is squeezed into an oddly shaped corner of the terrace.

We wanted to replace it with a 6ft x 6ft shed. This is the biggest standard size we could fit into the space available. We also wanted to keep the height of the shed to just over 6ft as it overlooks our neighbour’s back door.

A shed either has a pent roof, which goes from one side to the other in a slope. Or it has an apex roof, which is an upturned V. Both the pent and apex roofs were higher than 6ft at their highest point. (These are affiliate links to sheds on Amazon, which means that if you were to buy one, I may get a small fee. I’ve included them to show the difference between pent and apex roofs).

A ready-made shed may not maximise space

However, there are very few 6ft x 6ft sheds on the market.

So we decided to have the shed made for us by a local company called Lockhart’s. It fits exactly into the space and is slightly rhomboid.

Instead of being 6ft x 6ft, it is 6ft 3″” x 6ft”. We also asked for it to be an extra 6″ longer along one side, in order to fit exactly into the space available, so one wall is 6ft 9″.

Tailor made shed

This shed is only 2ft wider and a few inches longer than the old shed, but takes so much more inside. Note the very shallow roof, and the extra 6″ on the right hand side.

The roof has a very shallow slope. It looks almost flat. You can barely see it along the line of the fence.

Bespoke shed

The shed roof is just a few inches higher than the fence, and merges with it visually.

The extra two feet of width plus the extra few inches on the length has transformed our garden storage. As well as the garden chairs and the barbecue, we can also store three bikes, several brooms and a large folding table. We can walk into it easily, too.

How do the costs compare?

The total cost was around £1,200, using good quality ship-lap wood. Ready-made 6ft x 6ft garden sheds – if you can find them – typically range from £400-£800, depending on the quality of the wood. You may also have to pay extra for delivery, roof and other options and installation.

You can get DIY sheds online for less, but you will either have to put them up yourself or pay someone to do it, which will add to the cost.

You may think that it’s an exaggeration to call buying the wrong garden shed a ‘disaster’. But having exactly the right size and shape of shed, with the maximum storage capacity, is really critical when you’re short of space.

We  have ended up with a very simple, almost ‘invisible’ shed, but we are delighted with it. I’m looking forward to painting it next. There is shed painting inspiration here and here.

And to organise the inside of your garden shed…

We had the inside of our potting shed revamped by a young artist, who recycled things we had already to make clever, effective storage. He also lined the walls with artificial turf! For how to do it, see:

I love this Victorian shed in an Australian garden. I hope the owners never replace it.

    If you built a concrete base then put the shed on a layer of bricks you didn’t need the concrete base. All you needed was some footings to put the bricks on. A new potting shed roof £800. To be honest you could have built a 13X8 shed with tanalised wood for that price and still had change.

    1. It’s certainly possible to build a shed for £800 or less, but I don’t have the skills. And if I pay someone then that brings the costs back up again, because it’s usually at least two days of labour. And yes, you can have a shed just on a layer of bricks without a concrete base and lots of people do. But it’s not quite as sturdy because the earth settles and moves with, say, very wet or dry weather, and this can cause the bricks to move, and the shed can then shift too, making doors and windows not hang straight etc. It’s all a question of balancing the costs with other factors like your skills,how long you need the shed to last, what you want it to look like, how secure you need it to be etc. Thank you for commenting.

    It just shows if you can spend a little more on a decent then you do get better quality and something that would last alot longer.

  3. I have just moved into a house to which I have been met with an old, weather shed that needs replacing, so thanks for this article. It has come at a great time and I will be replacing the shed in the new year. Thanks for sharing!

    1. Oh, the joy of a new shed. I’m still pleased with ours every time I go into the garden.

    I wonder whether you expand to fit whatever space you have… personally.I think I’d be more tidy with less space. I have a corner shed, which is perfect for the space I have. Totally agree with you on the importance of the shed floor/base. Mine’s really badly made, and when it gets moved I’ll be reinforcing it with more battens.

    1. I think you’re right – I suspect our ‘perfect-sized’ shed will be crammed to the rafters within a few months, but at least it’s perfect now…we had been keeping the bicycles in the house, which really was inconvenient, and the folding table under a tarpaulin at the back of the garden, so at least it’s taken what we needed it to take. Now we must resist the temptation to expand into it….

    Thank you for this post. It’s actually a really important aspect of the garden, but often little thought is out into it. It makes everything in the garden simpler. Although, so many look at artificial grass, with a turned head, it actually can have advantages. There’s no mud during winter, or constant mowing, as it always looks in good condition. Of course, everyone change your lawn, but often just for small patchers, that perhaps don’t get much sun, or to use for a path to provide grip in the icy weather. There’s so many options.

  6. Sarah says:

    Very interesting!

  7. A really interesting article. Even though I don’t need a new shed it made me think that if we can it’s usually best to get the best we can afford and get exactly what’s needed rather than “make-do”. Thanks Alexandra.

    1. Thank – and I’m delighted to see that LondonCottageGarden.com is live! Congratulations (for anyone reading this, Julie has just started a blog on London cottage gardens, which will be interesting for anyone who loves cottage garden style and lives in an urban environment.
