What Size Should Your Oak Frame Garage Be? Design Guide for Devon Properties
One of the first decisions in any oak frame garage project is:
👉 How big should it actually be?
And this is where many projects go wrong.
Because people either:
underestimate what they need
or oversize the building without considering the property
The result?
👉 A garage that either doesn’t function properly — or doesn’t sit right within the setting
This guide breaks down how to approach size and design properly for properties in Devon.
Start With How the Garage Will Be Used
Before thinking about dimensions, start with function.
Ask:
Is it purely for parking?
Will you need storage space?
Is a workshop area required?
Are you considering a room above?
These decisions directly affect the size, layout, and structure.
👉 Trying to “add this later” usually leads to compromises

Single, Double or Triple Garage?
This is the most common starting point.
Single Garage
Suitable for one vehicle
Limited additional space
Often tighter in practical use
Double Garage
The most common choice
Provides space for two vehicles
Allows for better usability and storage
Triple Garage
More flexible
Can combine parking, storage, and workspace
Requires careful positioning to avoid overpowering the property
👉 The key is not just capacity — it’s how usable the space is day-to-day
Why Proportion Matters More Than Size
This is where good design makes the difference.
A garage that’s “big enough” can still look wrong if:
The roof pitch is too low
The span feels too wide
The building dominates the house
In Devon especially, garages often sit within:
Rural landscapes
Character properties
Visually sensitive settings
👉 Proportion matters just as much as size
Positioning the Garage on the Site
Where the garage sits is just as important as how big it is.
Consider:
Visibility from the main house
Relationship to driveways and access
Impact on surrounding views
Distance from boundaries
A well-positioned garage:
👉 feels integrated
A poorly positioned one:
👉 feels like an afterthought
Designing for the Property — Not Just the Idea
One of the most common mistakes is designing the garage in isolation.
Instead, it should:
Reflect the style of the main property
Match or complement materials
Sit comfortably within the setting
👉 This is what makes it feel like part of the property — not an add-on
How Size Affects Cost and Planning
Size decisions don’t exist in isolation.
They directly affect:
Budget
Planning requirements
Structural complexity
Larger garages:
cost more
are more likely to require planning
need more careful design

Getting the Balance Right
The goal isn’t to build the biggest garage possible.
It’s to build the right one.
That means balancing:
Function
Proportion
Budget
Planning constraints
When this is done properly, the result is a structure that:
works practically
enhances the property
and holds its value long-term
Avoiding Common Design Mistakes
Many issues come from:
Oversizing without considering the site
Undersizing and losing usability
Ignoring proportion and roof design
Not aligning with planning constraints

Get the Design Right From the Start
Size and design decisions shape the entire project.
Getting them right early avoids:
Redesign
Delays
Compromised results
