Not Your Average Garage.

We don't like to brag (who are we kidding, we LOVE to brag) but our garages are pretty special. Most companies make timber garages to a shed specification, but not us...
A Garage is Not Just a Garage...

We have have our own spec just for Garages because we know how important it is to get a building of such a size right.

You're probably looking for something substantial (not just any old garage). You want something that's capable of keeping your pride and joy safe, warm and away from moisture. Or you want a space to tinker away at whatever projects you pour your heart and soul into.

Traditionally Garages are for cars but there are all manner of things that they can be used for.

We've seen some incredible workshops, crafts and businesses made within the walls of our garages over the years.

It's an incredibly versatile build that many upgrade to include full insulation and lining – and ain't half bad to look at either.

We make a simple promise with our garages – they don't leak. Ever.

Technical Specification

If you’re familiar with Gillies and Mackay, you’ll know we don’t muck around with our specifications. We love nothing
more than to barter back and forth with new ideas, new technologies and a whole world of possibilities for design, specification and techniques.

Our Garages are made with a three-tier wall specification that looks and sounds a little something like this…

External Cladding

As standard we will always use 19mm thick tongue and groove redwood which has been tanalised to protect it against rot and fungi.


Water, as far as we’re aware cannot ‘jump’ - which is why a Cavity is the perfect solution to halting any moisture ingress through the external weatherboard. The cavity keeps the water on the outside and stops it from ‘jumping’ to the internal lining.

Breather Membrane

It’s a material that is water resistant but still allows air to flow. The membrane is lined between the cavity space and the OSB sheeting known as the cold side of the insulation. This prevents the moisture (as well as all the other elements) penetrating through to the internal of the building.

Oriented Strand Board (OSB)

We love a bit of OSB. It’s not our primary material it’s used as intended, to brace a structure. OSB is very strong and durable - Ideal for the internal structure of a wall rather than the finishing lining. Although there are plenty Hipsters who prefer a OSB lining just for the rustic look 😉

Pressure Treated Graded Framing

Depending on the size of structure we may use heavier timbers, but as a standard we will never use less than 95mm x 45mm pressure treated C24 Graded framing. The strength of this timber is what you would
expect to be used in new build homes.

We don't supply flooring for garages as these are typically built straight on top of the concrete plinth. You can however add your own flooring as seen in the picture here.


Steel Box Profile

This is our most favoured and common roofing option. We use Planwell, a fantastic firm in Buckie, Aberdeenshire. Murray and his team are amazing, they churn out massive quantities of Nova Permaroof for us on a fortnightly basis. The reason this option is so favoured is it’s 20 year guarantee and the fact it doesn’t leak! There are a couple of alternatives which are often preferred for Apex shaped roofs (pitched/pointed).


Electrics & Plumbing

At Gillies and Mackay we build the building because we’re joiners. We leave the other trades up to the skilled professionals. We do work closely with Electricians, Groundsmen and Plumbers to ensure these areas of the build go according to plan.

Light, Heating and Power.

These are the three things that make your Garage a space you can live, work and play in and thankfully electrics don’t need to be regulated by Building Control so assuming you’re not infringing on other areas - we’re able to build and hook you up without any added complexity.


Plumbing is a whole different kettle of fish and if you intend to tap in to the mains it will mean the entire building will need a warrant. You might prefer to look at alternative options, which don’t require building control.

How Much Does a Garage Cost?

As all our garages are custom builds, we can't give exact prices but here's a rough idea of what to expect from your build:


Small Garage

14 – 18m2

£7k - £9k


Medium Garage

19 – 24m2

£10k - £12k


Double Garage

Up to 30m2

From £13,000

Examples of things we cost for:

  • Manual / Automatic Garage Doors
  • Planning / Building Control (in few cases required)
  • The outer body
  • The inner body
  • Roofing
  • Windows
  • Doors
  • Car Port

Please Note:

If you’re planning on the building being bigger than 30m2 or running mains water to the building, it will require a Building Warrant and Engineers Certification.

This can add a considerable amount to the cost.
