What is a Mono Roof Garage?
A mono-roof garage is a timber garage with a single-sloping roof that falls from front to back. This design allows the building to reach a maximum height of 2.5m at the front before reducing to approximately 2m at the rear.
The layout is particularly popular because it makes efficient use of the available height while remaining suitable for many projects where planning restrictions are a consideration. By avoiding a traditional pitched roof, larger garages can often be accommodated without increasing the overall height of the structure.
Despite its lower profile, a mono-roof garage still provides ample space for cars, motorcycles, workshops, and general storage. The design works especially well for double, triple, and even larger garage layouts, making it a practical option when extending usable floor space is a priority.

Why Choose a Mono-Roof Garage?
A mono-roof garage offers several advantages over a traditional pitched-roof garage:
- Makes the most of the available space – The simple roof design allows you to get more out of internal floor space without unnecessary bulk.
- Ideal for larger garages – Double, triple, and even quadruple garages can be achieved while maintaining a lower overall building height.
- Planning-friendly design – The roof slopes from 2.5m at the front to approximately 2m at the rear, helping many projects remain within common planning restrictions.
- Contemporary appearance – A simple roof profile makes mono-roof garages particularly well suited to modern homes and landscaped gardens.
- Practical vehicle access – The full-width frontage allows straightforward access for cars, motorcycles, trailers, and larger equipment.
- Flexible internal space – In addition to vehicle storage, many customers use part of the garage as a workshop, hobby area, or general storage space.
- Cost-effective construction – The straightforward design offers an easy, practical, and efficient way of creating a large timber garage.
A Garden Garage for Modern Homes
If you’re looking for a garden garage that complements a modern property, a mono-roof design is worth considering. The clean roofline and straightforward shape create a simpler appearance than a traditional pitched-roof garage, making it a popular choice for contemporary homes and new-build developments.
The design works particularly well alongside modern landscaping, where uncluttered structures help create a more cohesive look across the property. It can also be finished with different cladding and door options to suit the style of the house.
While mono-roof garages are often chosen for their practicality, many customers are equally attracted to their understated appearance and ability to blend naturally into modern surroundings.
Popular Uses for a Mono Roof Garage
A mono-roof garage can be used for much more than parking a car, including:
- Daily vehicle parking – Keep cars protected while maintaining easy access for everyday use.
- Workshop space – Create a useful area for tools, benches, and DIY projects.
- Hobby storage – Useful for bikes, sports equipment, restoration projects, or specialist kits.
- Motorcycle storage – Provides secure and covered storage with room for maintenance.
- Garden machinery – Store mowers, strimmers, and larger equipment away from the house.
- Home business storage – A useful space for stock, tools, or materials where a separate outbuilding is needed.

Design & Customisation Options
Mono-roof garages are available in a wide range of sizes, from single garages through to double, triple, and quadruple-bay layouts. This flexibility makes them suitable for everything from a single-family car to larger vehicle collections, workshops, and storage requirements.
The online configurator allows you to customise the building to suit your needs, including the addition of windows and personnel doors. These options can improve natural light, create separate access points, and improve usability day-to-day.
As standard, garages are clad in pressure-treated shiplap boarding, with the option to upgrade to feather-edge cladding for a different appearance. A variety of garage door styles are also available, allowing you to create a building that works for both your property and intended use.
If you require dimensions outside the standard range, please contact our team to discuss alternative sizes and layouts.
Construction & Specifications
Each mono-roof garage is built using quality timber construction, creating a strong and practical building for vehicle storage, workshops, and general use.
- Pressure-treated shiplap cladding – Supplied as standard for long-lasting protection against the elements.
- Feather-edge cladding upgrades – Available for customers who prefer a different appearance.
- Steel box-profile roof sheets – Durable and designed to provide reliable weather protection.
- Timber-framed structure – Engineered to support the building while maintaining the clean edge of the mono-roof design.
- Visible internal framing – The structural timbers remain exposed internally unless an optional lining package is selected.
- Optional insulation and lining – Internal roof lining and insulation can be added where a warmer, more finished interior is required.
Delivery & Installation
Installation is included with most mono-roof garage projects, with our experienced team assembling the building on site once the groundwork has been completed. This helps ensure everything is fitted correctly and ready for use as quickly as possible.
If you would prefer to install the garage yourself, a supply-only option is also available. Delivery costs can be calculated through the online configurator by entering your postcode as part of the quotation process.

Groundwork Requirements
A mono-roof garage requires a level base to ensure the building performs as intended over the long term. In most cases, this will consist of a concrete base with a single course of bricks around the perimeter, helping to separate the timber structure from ground moisture.
To make preparation straightforward, we provide foundation plans showing the required dimensions and layout for your chosen garage. These can be passed directly to your contractor before installation begins.
Correct groundwork is one of the most important parts of any garage project, helping to ensure a smooth installation and a long-lasting building.

Internal Views
The framing is visible on the inside of the garages unless you choose the inside lining option.
On the back of the framing, you will see the 4mm plywood, which has the vapour barrier and then the outside cladding.
Inside the building, you will see the purlins (between the trusses) followed by the sterling board (OSB). On the outside of the OSB is the final roof covering.
If you select the option of the internal roof lining (and insulation), the Celotex is fitted in between the purlins, and 9mm plywood is fixed to the underside of the purlins.
Garage Door Options
Mono roof garages can be supplied with a range of door options, depending on the look and access you need:
- Canopy-style up-and-over doors – Supplied as standard and available in a choice of colours.
- Fully retractable up-and-over doors – A useful upgrade if you prefer a different opening style.
- Timber-framed doors – A good option if you want a more traditional garage appearance.
- Cedar-clad doors – A smart timber finish that works well with upgraded cladding.
- Third-party doors – We can leave the openings ready if you want to arrange your own roller shutter doors, automated doors, or another specialist option.
Door choice can affect both the appearance and everyday use of the garage, so it’s worth considering how often you’ll access the building and what you plan to store inside.

Maintaining Your Mono-Roof Garage
Mono-roof garages come with a 10-year guarantee covering design and manufacturing faults. To keep the building in good condition, a small amount of regular maintenance is recommended.
- Keep the roof and guttering clear of leaves and debris, especially after poor weather.
- Doors and windows may also need occasional adjustment as timber naturally expands and contracts throughout the year.
- External timber should be treated as required to help protect it from moisture and maintain its appearance.
With basic upkeep, your mono-roof garage will remain strong, practical and reliable for years to come.

FAQ's
Can you build bespoke sizes?
Yes. While the online configurator includes a range of standard sizes, we can often modify dimensions and layouts to suit individual requirements.
If the size you need isn’t shown online, please contact our team to discuss the available options.
Will a mono-roof garage look right next to a traditional home?
Although mono-roof garages are often associated with contemporary properties, they can work equally well alongside more traditional homes. Cladding choices, door styles, and colour selections all help to create a building that complements its surroundings.
Can the garage be insulated?
Yes. Insulation and internal lining options are available for customers who intend to use the garage as a workshop, hobby space, or for storing temperature-sensitive items.
What garage doors can I choose?
Standard canopy-style up-and-over doors are included, with upgrades available to retractable doors, timber-framed doors, and cedar-clad doors. We can also leave the openings ready for third-party doors if you have a preferred supplier.
Can I add windows and personnel doors?
Yes. Windows and personnel doors can be incorporated into the design to improve access, increase natural light, and better suit the building for workshop or storage use.
Are mono-roof garages suitable for SUVs and vans?
For most vehicles, yes. The design provides generous internal space despite its lower overall height. If you own a particularly tall vehicle, we recommend checking the door and internal dimensions before placing your order.
Can I build a large mono-roof garage without planning permission?
In many cases, yes. Mono-roof garages are specifically designed to work within common permitted development guidelines, with a maximum height of 2.5m at the front.
Planning requirements can vary depending on your property and location, so we always recommend checking with your local authority if you’re unsure.
Why is a mono-roof garage popular?
Mono-roof garages are popular because they provide a large amount of usable space while maintaining a relatively low overall height. The single-sloping roof design is often a practical solution where planning restrictions are at play.
