📐 1. Get the Size Right

🪑 Measure Your Space First

Before browsing designs, measure the area where you want your arbour:

• Width — how wide can the arbour be without crowding plants or paths?
• Depth — make sure doors, benches, or walkways aren’t blocked.
• Height — tall arbours suit climbing plants and give a sense of space; lower designs suit compact gardens.

👥 Think About Use

• Seating arbour: Allow at least 60–70cm depth for comfortable bench seating.
• Walk-through feature: Prioritise height and width over depth.
• Corner arbour: Works well in tighter spaces but ensure enough room for knees when seated.

🌿 Rule of Thumb

Leave at least 60–90cm of clear space in front of the arbour so the area feels open and accessible.

🪵 2. Choose the Right Timber

Timber choice affects how long your arbour lasts, how much maintenance it needs, and how it weathers UK conditions.

🛡️ Pressure-Treated Softwood

• Most affordable and widely available
• Treated to resist rot, insects, and damp UK weather
• Good long-term performance when kept well-ventilated and oiled annually

Best for: general garden use and larger structures.

🌲 Cedarwood

• Naturally resistant to rot and insects
• Attractive grain and colour
• Requires less preservative treatment than softwood

Best for: low-maintenance gardens or rustic aesthetics.

🌳 Redwood / Redwood Cedar

• Durable and stable
• Naturally weather-resistant
• Slightly premium price

Best for: long-lasting, quality arbours with minimal upkeep.

🪵 Untreated Softwood

• Cheapest option
• Requires regular oiling and sealing
• Not ideal for very wet climates

Best for: sheltered gardens or structures that are covered.

🔩 3. Fixings & Hardware That Last

The strength of an arbour depends heavily on the fixings — these hold the structure together and prevent loosening over time.

🛠️ Use Galvanised or Stainless Fixings

• Galvanised screws/bolts: Good rust resistance and strength
• Stainless steel fixings: Best for coastal or very damp locations

Avoid basic zinc-plated or untreated nails and screws — they corrode quickly in UK conditions.

🧰 Bolts Over Nails

Bolts with nuts and washers create stronger joints than nails or staples. They’re easier to tighten if the arbour loosens with age.

🪚 Brackets & Metal Plates

Corner brackets and reinforced plates add rigidity to the frame, reducing wobble and improving longevity — especially in larger or freestanding designs.

🌦️ 4. Weatherproofing & Protection

Even quality timber needs protection in the UK:

• Seal cut ends: Apply preservative to exposed board ends after cutting.
• Annual maintenance: Re-oil or re-stain southern and western exposures.
• Keep base clear: Set arbours on paving, gravel, or concrete blocks — not directly on soil to reduce rot risk.
• Plant placement: Position plants beside but not right against timber to allow airflow.

🪴 5. Style & Function Considerations

🌿 Trellis Sides

Great for climbing plants and visual interest. Look for sturdy lattice with thicker slats that won’t warp.

🍃 Roof Design

• Solid roof: Best for shade and light rain protection
• Slatted roof: Offers dappled shade and a lighter feel

🪑 Seating vs Feature

Decide if you want the arbour mainly as a seating area or a decorative garden feature. Seating arbours need deeper platforms and comfortable back support; feature arbours prioritise height and planting structure.

🧠 6. Plant Integration Tips

Plants can make an arbour feel more natural and sheltered:

• Climbers: Sweet peas, clematis, roses and jasmine work well
• Training: Guide stems early to spread evenly across trellis
• Maintenance: Trim lightly to prevent excess weight on structure

Pro tip: Add seasonal colour with pots placed around or beneath the arbour.

🏡 7. Placement & Orientation

Consider:

• Sun path: Face seating away from harsh midday sun or strong winds
• View lines: Place where the arbour frames a garden vista
• Protection: Near fences or walls for extra shelter and structural support
