3 Bay Oak Garages

Why Choose an Oak Garage Over Concrete or Steel?

When comparing a wooden garage to concrete or steel alternatives, oak framed construction offers significant advantages:

• Aesthetic appeal: Enhances property value and character — natural oak blends beautifully with any home
• Customisation: Fully bespoke oak garage designed to your exact requirements
• Longevity: Oak garages last 100+ years with proper care, compared to 20–30 years for concrete or steel
• Flexibility: Easy to modify, extend, or convert oak frame structures
• Environmental: Sustainable, renewable timber construction with a low carbon footprint
• Planning advantage: Oak framed buildings are more likely to gain planning consent than industrial alternatives
• Comfort: Natural insulation properties make oak ideal for workshop use

We build triple garages across Sussex, Surrey, and Kent, with three-bay designs that can incorporate a workshop, home gym, or room above alongside the parking bays.

Our three bay garage designs begin with a consultation to establish width, pitch, and intended use — three bay garages are particularly popular with clients who want two full parking spaces plus a dedicated storage or workshop bay.

3 Bay Oak Garage Design Options

Your triple oak garage can be configured to suit your exact requirements. Here are the most popular layout and design options:

Layout Configurations

• Triple vehicle parking: Three enclosed bays with individual oak garage doors for maximum security — optimal spacing of 2.6m–3.0m bay widths accommodates modern SUVs
• Two cars + workshop: Two parking bays plus a dedicated workshop space with workbenches, tool storage, and separate access
• Car + storage + office: One parking bay, general storage area, and home office space above
• Carport + garage + store: One open-fronted oak carport bay, one enclosed bay, and secure storage
• Classic car haven: Three bays optimised for vintage vehicle storage with climate considerations

Roof Styles

• Gable end: Traditional pitched roof design
• Hipped roof: Elegant four-sided roof structure
• Barn end: Rustic agricultural styling for rural properties
• Catslide extension: Additional lean-to for log store or equipment

Access Options

• Single oak garage doors (2.4m–3.0m) for each bay
• Double doors spanning two bays for wider access
• Sliding doors for space-saving operation
• Up-and-over doors with manual or electric operation
• Side-hung traditional barn doors

Roof finishes include clay tiles, natural slate, or cedar shingles. All garages are made from high-grade green oak and can be supplied as part of a full design and build service.

3 Bay Oak Garage Dimensions

All our oak garages are built to bespoke dimensions. The sizes below are typical starting points — we’ll adjust every measurement to suit your vehicles, your site, and your intended use.

Need something smaller? See our 1 bay or 2 bay oak garages. For larger requirements, explore our 4 bay oak garages. If your site requires a non-standard layout, our L-shaped oak garages may be ideal.

3 Bay Garage with Room Above

Transform your 3 bay garage into a multi-storey building with a garage with room above. The generous footprint of a triple garage provides excellent upper floor possibilities:

• Home office: Dedicated workspace and meeting area away from the house
• Guest bedroom: Comfortable bedroom with en-suite facilities
• Self-contained annexe: Independent living space for family or rental income
• Hobby room: Space for crafts, model making, music, or creative pursuits
• Storage loft: Generous space for seasonal items and equipment

A two-storey oak garage maximises your investment, creating living quarters that add genuine value to your property. While it’s possible to add an upper floor later, we recommend including it in the initial design — the frame needs to be engineered for upper floor loads, and building in one phase is far more economical. We can also design your 3 bay oak garage “room-ready” with structural capacity for future expansion.

Planning Permission for a 3 Bay Oak Garage

Three bay oak garages typically require full planning permission due to their size — a standard triple garage has a floor area of 45–65 square metres, which usually exceeds permitted development limits. Key considerations include:

• Floor area and height restrictions under permitted development
• Position relative to the principal elevation of the house
• Curtilage coverage — the garage must not exceed 50% of total garden area
• Conservation area, AONB, or listed building restrictions

If you’re adding a room above, the garage becomes two storey and will always require planning permission. Our experience with local planning authorities means we can guide you through the process — we offer a full planning application service and manage everything on your behalf.

Building Regulations

Detached garages under 30 square metres that are at least one metre from any boundary are generally exempt from building regulations. However, a 3 bay garage will almost certainly exceed this threshold, so building regulations will apply. If you’re adding a room above, full building regulations compliance is mandatory. We’ll confirm exactly what applies to your project during our initial site visit.

How We Build Your Triple Oak Garage

1. Initial Consultation

We visit your site, discuss your requirements, and assess the practicalities — access, ground conditions, and any planning considerations. There’s no charge for this initial visit.

2. Bespoke Design

Our design team creates detailed plans tailored to your site and intended use. We’ll work through dimensions, bay configurations, door styles, and roof finishes until the design is exactly right.

3. Planning & Approvals

We confirm whether your garage falls under permitted development or requires a planning application. For most 3 bay garages, a planning application will be needed — we prepare and submit everything on your behalf.

4. Oak Frame Manufacture

Your oak frame is hand-crafted in our workshop using traditional mortise and tenon joinery. Each joint is individually cut and test-assembled before delivery. For a triple garage, we use 150mm x 195mm green oak posts for superior structural strength.

5. Site Preparation & Foundations

Groundworks and foundations are prepared while your frame is being manufactured, keeping the build timeline efficient.

6. Frame Raising & Completion

The oak frame is delivered and erected on site — typically completed in three to five days for a triple garage. Roofing, cladding, doors, and finishing works follow promptly.

Typical timeline: 10–14 weeks from sign-off to completion, depending on specification and site conditions.
