Garden Storage Planning Questions Checklist

Walk the garden, the side passage and any existing store and write down everything you find, including the things that have simply been left where they were last used.

A list written on site is usually longer than one written indoors, and that difference is often what leaves storage undersized.

Identify the longest and the most awkward item on your list, such as a ladder, a folded table or a rolled hose, and note its rough dimensions.

The longest item often drives the internal length or the door opening, and it is one of the more useful things to have written down.

Count the wheeled items that need storing, including bikes, a mower, a barrow and a bin, and note whether any of them has to come out first to reach the rest.

Wheeled items need floor area and a clear run to the door, which is a different requirement from shelf space.

Note which items are only needed for part of the year and whether two seasonal sets could share the same space rather than both being stored at once.

Seasonal rotation can reduce how much space is needed at any one time, but only if the swap is genuinely practical for your household.

Mark each item as reached often, occasionally or almost never, since that order of priority is what decides where things sit rather than how large they are.

Frequently used items need to be at the front, and a store designed without that order becomes unusable within a season.

Decide honestly what you are storing only because it is already there, and record what would go before the new store is sized.

Sizing a store around items nobody intends to use again is a common and wasteful habit.

Note how far each candidate position is from where the stored items are actually used, and whether the route between them involves a step or a turn.

A store placed for looks alone stops being used, and the tools drift back to wherever is closer.

Stand at the main rear window and check what a store in each candidate position would do to the view, including whether it blocks the longest sight line.

Stores are large, static objects, and in a modest garden their effect on the view is greater than their footprint suggests.

Consider how much shade a store would cast in each position and on what, particularly if there is planting or seating behind it.

A store casts a permanent shadow that changes what can grow or be enjoyed behind it.

Note whether you could get around the store to maintain the sides and the back, or whether one face would become permanently unreachable.

A store pushed tight into a corner is very difficult to maintain, and the hidden face is the one that deteriorates.

Check whether any inspection cover, drain, meter or service run sits in the candidate position, and ask what access has to be preserved.

Building over an access point is easy to do and disproportionately awkward to reverse.

Before a store is positioned over anything, the utility or a qualified professional should tell you what access has to stay available to it.

Trace how the store or its parts would physically reach the chosen position, and record the narrowest point and the tightest turn on that route.

Access frequently rules out the preferred form of store, which is better discovered before anything is ordered.

Note what the ground is at the chosen position, whether soil, grass, an old slab or made up ground, and whether anyone knows what lies beneath it.

The existing ground is the first thing a professional will ask about when a base is being considered.

Observe whether water collects at that spot after heavy rain, and record how long it takes to clear once the rain has stopped.

A store on ground that holds water is likely to suffer from damp however well the store itself is made, so the observation matters.

Note whether the position is level or falls in one direction, and record which way, since that affects both the base and where water runs afterwards.

A sloping position changes the base substantially, and knowing the direction of fall early avoids a redesign.

The design of any base, including levelling, support and drainage, should be established by a qualified professional for your ground conditions.

Ask the store supplier what base they require, and record their answer before assuming an existing slab or paved area is suitable.

Supplier requirements vary, and using an unsuitable base is a common reason a store fails early.

Whether an existing slab or paved area is suitable must be confirmed by the supplier and a qualified professional rather than assumed from appearance.

Ask where water shed from the roof of the store would go, and whether it would run towards the house, a boundary or a planted area.

Even a small roof sheds a surprising amount of water at one edge, and where it lands affects both the base and whatever is planted nearby.

A qualified professional should establish where roof water from the store ends up, and the local position on surface water needs confirming separately.

Consider what would be left behind if the store were removed later, and whether the base would be reusable or would have to be taken up.

Thinking about removal at the outset often changes what kind of base is worth putting in.

Note which way the doors would open and how much clear space is needed in front of them, then check that space is not taken by a bed, a path or a bin.

Door swing space is routinely overlooked and is the reason many stores end up with doors that cannot be fully opened.

Check that the widest item on your list would pass through the proposed opening without being tilted, since some items cannot be turned once loaded.

An opening that works for a person may not work for a mower or a bike with handlebars.

Ask whether there would be a threshold or lip at the door, and how a wheeled item would be taken over it without lifting.

A raised threshold turns a bike store into a lifting exercise, which quickly stops it being used.

Consider whether you would be able to reach the back of the store without emptying the front, and whether the depth chosen makes that realistic.

Depth beyond arm reach only works with a way in from both sides or with a very disciplined layout.

Note whether the doors open into the prevailing wind and whether you would be standing in the rain while loading, given where the roof edge sits.

Orientation of the opening determines whether the store is comfortable to use in the weather when it is needed most.

Decide whether you need to see inside the store in the dark, and ask a qualified electrician what providing light there would involve.

Stores are most often used in poor light, and planning for it early is far easier than adding it later.

Taking a supply out to an outbuilding is work for a qualified electrician alone, and they should tell you what the local requirements are for it.

Accept that an unheated outdoor store will move with the weather, and list which of your items would be damaged by damp or by repeated temperature swings.

Sorting the list into what tolerates outdoor conditions and what does not usually shortens the storage requirement.

Ask the supplier and a qualified professional what ventilation the store needs, and whether the position you have chosen restricts airflow around it.

A store pushed against a wall or hedge often cannot breathe, which is a frequent cause of damp contents.

Ventilation requirements for any store, particularly one holding equipment or fuel, should come from the supplier and a qualified professional.

Note which items would suffer most from condensation, such as anything with a metal surface or fabric, and decide whether they should be stored elsewhere.

Condensation can be more damaging to stored equipment than rain reaching it, and it is often not considered at all when a store is chosen.

Ask the supplier of any fuel, treatment or garden chemical what their storage requirements are, and record the answer before anything is kept in the store.

This is a supplier and professional question in every case, and the answer may rule out a shared store entirely.

How fuels, treatments and garden chemicals should be stored, ventilated and separated must come from the product supplier and a qualified professional.

Consider whether items would sit directly on the floor, and note which would benefit from being kept off it given how the base is likely to behave.

Floor contact is often where damp damage begins in an outdoor store, and it is easy to plan around once it has been noticed.

Write down how the store would be emptied and cleaned periodically, and whether there is anywhere to put the contents while that happens.

A store that cannot be emptied easily never gets cleared out, which is how it fills with things nobody uses.

Ask your insurer what they expect of outdoor storage for the items you intend to keep there, and record their answer in writing before choosing a store.

Expectations differ between policies and items, and asking first is far easier than discovering a requirement afterwards.

Only your insurer can tell you what your policy expects of outdoor storage; nothing on this page should be treated as an answer to that question.

Note what would be visible when the doors are open and from where, including any point outside the boundary that overlooks the store.

Visibility from beyond the boundary is a simple thing to observe and often influences where a store is placed.

Ask the supplier how the doors, hinges and any fixings are arranged, and record what they say rather than judging the store from a photograph.

The parts that matter for security are rarely visible in product images, so the question has to be asked directly.

Ask whether the store and its contents can be anchored to the base, and what the supplier and a qualified professional require for that.

Anchoring often depends on the base, which is another reason to settle the base question before ordering.

How a store or its contents should be anchored must be established by the supplier and a qualified professional, not improvised on site.

Consider whether the approach to the store is lit or overlooked from the house, and record which windows can see it.

The approach to a store often matters as much as the store itself, and it takes only a moment standing at the window to observe.

Keep your own written record of what is kept in the store, updated when significant items are added, and hold it somewhere other than the store.

A current record is the thing most often missing when it is needed, and it takes very little to maintain.

Before settling on a size or a position, find out from local sources what applies to an outbuilding of the kind you have in mind.

What is possible depends on where the property is and what kind of property it is, so this can only be answered locally.

Only your local authority or a qualified adviser can tell you what consent position applies to an outbuilding of this kind on your property.

Check whether your title documents, lease or any covenant mention outbuildings, and note anything you do not understand for an adviser to interpret.

Property specific restrictions are easy to miss and are entirely separate from any local authority position.

Covenants, leases and title restrictions should be interpreted by a qualified conveyancer or solicitor rather than read at face value.

Note how close the store would sit to a boundary, and ask what maintaining its far side would involve if it stands tight against a fence.

A store against a boundary can make the fence behind it impossible to repair without moving the store.

Consider what a neighbour would see from their windows or garden, and decide whether you would rather mention it before it appears.

Raising it first is usually straightforward, while explaining it afterwards rarely is.

Ask who is responsible for a shared passage or path if the store has to be brought in that way, and record any permission you need to obtain.

Delivery over shared land is a permission question that is easier settled before an order is placed.

Agree in writing with whoever supplies or builds the store what is included, including base, delivery and making good, and keep that record.

Base and delivery are the two items most often assumed to be included when they are not.
