The Building Proccess, Planning & Prices

My builds are superior to pre-fabricated units bought from retailers, they are built to exceed current building regulations. My advice is to call me, to check the build is suitable and we can arrange for a site visit. My in house architect can also help you with design, planning & consultation.

Shed Building Breakdown

The table below may help you understand your input in the building process.
Build Proccess Overview & Options to Consider Time

Shed Planning & Permitted Development

You are allowed to build without planning permission, within these basic guidlines. Our in house architect can help you with a suitable design or to apply for planning permission.

  • The Area must not exceed 50% of the total area of land around the house
  • The height must be a maximum of 2.5m at the eves and a maximum overall height of 4m
  • If the boundary is within 2m, the building should not exceed 2.5m in height

A breakdown of Basic Shed Prices

A good estimate for my builds is between £600 & £800 per square meter. The prices below are a basic rough guide for completed exterior and interior.
Dimensions Total Area Pine Work Studio
Larch Living Roof Shed Rendered/Tiled Garden House
2m x 3m 6m sq. £3600 £4200 £4800
2.4 x 4.2m 10m sq. £6000 £7000 £8000
3m x 5m 15m sq. £9000 £10500 £12000

Because each shed we do is different, we can build the shell of the building for a fixed price and then work on a day rate to complete the bespoke elements. There are any number of optional extras to support your plans, from custom made sheving and desks, to specifically designed acoustic solutions for music studios. Our in house architect can help you make the correct decisions for your build and your budget. To see some of my finished builds, go to GALLERY >

Shed Bespoke Options, custom made solutions

Just some examples of our design options


A bespoke desk can be made to size to maximise the surface area available. They can be fitted the full width of the build.


Custom made shelving can be integrated into the walls of the build. Also notice the custom made folding desk and oak flooring.


It's useful to consider furniture you already have and like. We can design a build in keeping with a period or style.


Sometimes more specific solutions are required for builds such as recording studios. Perhaps acoustic isolation using resilient bars, acoustic plasterboard or custom made sound diffusers.

bespoke shed roof windows

Custom made skylights or roof windwos can be integrated to bring more natural light into the build, or consider something unusual like a port hole.


If you can see your roof at any point, it is a nice idea to consider a sedum roof. It's great for nature and helps blend it into your garden.

Step by Step, a breakdown of a build in photos

This is just one example of a Garden House Build.


The Area of the Build is cleared and levelled either manually or excavated depending on how large and uneven the ground.


A waterproof barrier to stop damp and optional insulation is laid before a four inch structural concrete slab is poured.

frame out

The frame is built with high grade structural timber, pressure treated and with preservative to ensure a long life. The framework is then boarded out with ply.

breathable membrane

The build is covered with breathable waterproof membrane which allows natural moisture to escape out - but prevents moisture from entering in. A roof window is added.


The roof was stregthened with ply, again covered in breathable membrain, batoned out & tiled. Window is sealed and then flashing added.

cladding, fascia & render preparation.

Treated Timber cladding is added to the sides, A fascia board added, initial window and door frames go in. A mesh is added to hold the render.


The front walls are rendered with two coats, roof tiles are sealed and doors fitted.

internal insulation & plastering

The internal walls and roof are insulated with rockwool, or kingspan, the walls are plasterboarded and skimmed this also helps with sound insulation and effeiciency.

paint & windows

The windows are fitted with thick safety glass, skirting is added then the build is finished with internal and external painting.


This floor was tiled, often an internal timber floor structure is covered in tongue and grooved timber floor boarding creating a solid foundation for any additional flooring.

final touches

Final touches, just guttering to be added and water taken to soak away or to a waterbut.


The Garden House is put to use with a family meal.
