Is it cheaper to build your own shed?

Is it cheaper to build your own shed?

DIY home projects are becoming increasingly popular. With the sense of achievement you receive afterwards and the cost reduction, we can understand why this may be a favourable option. 

But is it really cheaper to build your own shed? With the cost of materials and tools and the time and effort a job like this takes, it’s important to consider whether you’re truly committed to the task.

We will explore the factors that come into a DIY project at this level, determining whether you’re saving more overall than you would if you bought a pre-built shed. 

The cost of buying a shed

Pre-made sheds

With a busy work schedule and a chaotic home, pre-built sheds are a saving grace. This allows you to browse a range of options, choose a shed perfect for your needs, and have a solid idea of what the finished product will look like in your garden. 

The cost of a pre-made shed can vary significantly depending on its size, materials, and features. You might expect to pay around £300 to £500 for a basic wooden shed. However, for a larger, more robust structure with additional features like windows, shelving, and higher-quality timber, the price can easily go up to £2,000 or more.

Plastic sheds are generally the cheapest option, set at around £200. However, they are a less popular choice as many view them as unattractive, and the material is less durable. 

Wooden sheds are more costly. However, they provide a garden with elegance and sophistication, and their longevity means you’re saving more money in the long term.

Added costs such as installation and delivery will add to your purchase. Although many places offer free services, reducing the overall cost.

Custom-made sheds

Opting for a custom-made shed allows you the freedom to design it to fit your specific needs and aesthetic desires; however, this level of personalisation often comes at a higher price. 

You might expect to pay anywhere from £1,000 to £3,000 for a basic custom shed. For larger, more elaborate designs, the cost can easily exceed £5,000. 

Custom metal sheds are generally less expensive than their wooden counterparts, but they can still cost upwards of £1,000, depending on the design. The most affordable options are made from composite materials, yet even these cost between £1000 and £3000, which most people will agree is expensive for a garden shed.

The cost of labour and installation can increase the overall cost by up to £1000, and if it requires planning permission, this will put a bigger dent in your wallet. From electrical wiring to insulation and custom finishes, you should factor these into your budget if you want a custom-built shed.

Materials and tools

Here is a list of the materials and tools you will need to build your shed. You should factor in each item's price to calculate the project's overall cost. 

  • Timber, Plywood, Oak, or Pine
  • Roofing material: asphalt shingles, metal roofing, or corrugated plastic sheets.
  • OSB sheets- walls, flooring, and roofing
  • Concrete blocks or piers
  • Siding: wood, vinyl, or metal sheets.
  • Paint or stain
  • Doors, windows and trim
  • Door Hardware: hinges, handles, and locks.
  • Fiberglass or foam board for walls and ceiling.
  • Plywood, laminate, or concrete for flooring.
  • Guttering and vents.


  • Tape measure
  • Hammer
  • Screwdriver or drill
  • Circular saw
  • Level
  • Ladder
  • Utility knife
  • Pencil
  • Safety gear (gloves, goggles, ear protection)


While building your own shed can save you a lot of money, it can cost you a lot of time. Depending on your skill, stamina, and strength, a task like this can take you anywhere from days to weeks to complete. 

If you're not comfortable doing the entire project yourself, you may need to hire a professional for specific tasks:

  • Electrical wiring: £100 to £300
  • Roof installation: £200 to £500
  • Foundation work: £150 to £400

If you’ve never worked on a project to this level before, you must consider the possible mistakes you will make and the extra materials you will need to cover them. It is always best to purchase extra material in case of damage or loss of property.

Permits and regulations

If you are required to obtain a building permit for your shed, there may be a cost to pay to the council. This can range anywhere between £50 to £200. 

Inspections are sometimes required to check if the shed is fit for installation in your home. This can cost anywhere between £100 to £200, and it is important to check if it is required as it may cost you a fine.

Hidden costs

Aside from the cost of materials, tools, and any necessary permits, you must include costs for future repairs and maintenance of your new shed in your budget. 

A DIY shed will likely be less durable than a professionally built shed, meaning repairs are more likely. However, a do-it-yourself shed can turn out just as good if the appropriate time, effort, and materials are applied.
