About Our Metal Gazebos
We stock 26 metal gazebos, garden tunnels, and arbours from two specialist suppliers: Ascalon (ornate wrought iron designs) and Garden Must Haves by Norfolk Leisure (modern aluminium with canopy options). The collection splits into three categories: open iron gazebos designed for climbing plants and as garden centrepieces, Gothic-style garden tunnels that create dramatic walkways, and modern hard-roof gazebos with polycarbonate panels and sliding roofs for genuine weather protection. Prices start at £219 for the Heritage Grey Arbour Bench and range to £1,499 for the Avignon Gazebo with Canopy.
Every iron and steel structure is powder-coated with UV-resistant paint for year-round outdoor use. The Ascalon range features galvanised steel with hand-finished scrollwork in matt black, bronze, cream, blue, and white finishes. The Garden Must Haves range uses powder-coated aluminium with hardened polycarbonate roof panels. Browse our full metal garden ornaments collection for matching arches, gates, and furniture.
Why We Chose This Range
"I spent months testing gazebos before settling on Ascalon and Garden Must Haves. The cheap imports you find on Amazon look decent in photos, but the steel is thin and the powder coating chips within the first winter. Our Ascalon pieces use properly galvanised steel — you can feel the weight when you pick up a post section. The Garden Must Haves range is different again: engineered aluminium frames with genuine polycarbonate roofs, not flimsy fabric canopies that tear in the wind. Two very different products, but both built to last in British weather."

Arched walkway structures that create dramatic covered passages. The Gothic tunnels from Ascalon span up to 4 metres with pointed arch profiles in bronze or cream (£1,145-£1,150). The Parisienne tunnels offer a lighter option in cream, lead grey, or rusted iron at £279. Ideal for training climbing roses, wisteria, and clematis.

Matt's Pick for Best All-Round GazeboBest For: Traditional gardens and climbing plant displays Why I Recommend It: The Cockerell is the gazebo I'd put in my own garden. It has the right proportions — tall enough to walk under comfortably, wide enough for a small table and two chairs, but not so large that it dominates a medium-sized lawn. The scrollwork on the posts is properly detailed, not the stamped-out patterns you get on cheaper models. After two seasons with a climbing rose trained up it, this gazebo becomes a genuine garden centrepiece. At £545 it sits right in the middle of the range — serious quality without the £999 price tag. Price: £545 |
Matt's Installation Tip
A metal gazebo must be anchored to a solid base — never just placed on grass or soil. For open iron gazebos, bolt the feet into a concrete pad or use heavy-duty ground anchors driven into compacted hardcore. The minimum base should be 150mm larger than the gazebo footprint on all sides. For the aluminium Garden Must Haves range, a level patio or concrete slab is essential — these are engineered structures and even 10mm of unevenness puts stress on the frame joints. Allow 3-4 hours for assembly with two people. Check all fixings again after the first month and at the start of each season.
Gazebo Placement & Planting Guide
- Open iron gazebos: Position at the end of a lawn or in the centre of a formal garden. Train climbing roses (David Austin ramblers work particularly well), wisteria, or honeysuckle up the posts. Allow 2 growing seasons for full coverage.
- Garden tunnels: Align with an existing path to create a covered walkway. Plant alternating varieties each side — try a mix of clematis and jasmine for colour and scent through spring to autumn.
- Modern hard-roof gazebos: Position on a patio near the house for easy access. Add outdoor furniture, festoon lighting, and side curtains to create a genuine outdoor room. The Runcton models with louvred sides work well for hot tub enclosures.
- Planning permission: Most garden gazebos under 3m tall fall within permitted development rights. If you're in a conservation area or your property is listed, check with your local authority before installation.

Frequently Asked Questions
Most garden gazebos under 3 metres tall fall within permitted development rights. This means you won't need planning permission for a standard-sized structure in your back garden. However, if your property is listed, in a conservation area, or you want to place the gazebo in the front garden, you should check with your local planning authority first. All our gazebos are designed for domestic gardens and fall within typical permitted development height limits.
A firm, level surface is essential — concrete paving or a purpose-poured slab. The base should extend at least 150mm beyond the gazebo footprint on all sides. For open iron gazebos on grass, you can use heavy-duty ground anchor bolts driven into compacted hardcore, but a paved base is always the better option. For the aluminium Garden Must Haves range, a perfectly level patio or concrete slab is mandatory — the polycarbonate roof panels won't seat properly on an uneven frame.
Allow 3-4 hours for two people with basic tools. All our gazebos come with fixings and assembly instructions. The open iron designs from Ascalon bolt together in sections — posts first, then cross-bars, then decorative scrollwork. The Garden Must Haves aluminium range requires a ratchet set and spirit level. We recommend a dry, calm day for assembly. Check and retighten all bolts after the first month as the structure settles.
Our iron gazebos are galvanised then powder-coated for rust resistance. Galvanisation coats the steel in zinc, which prevents corrosion even if the paint chips. Touch up any scratches with matching metal paint before winter to keep the finish intact for decades. The aluminium Garden Must Haves range cannot rust at all — aluminium is naturally corrosion-proof. See our weatherproofing guide for seasonal care advice.
Open iron gazebos are decorative garden features; hard-roof gazebos provide genuine weather protection. Open designs from Ascalon have ornate metalwork frames without solid roofs — they're designed for climbing plants, visual impact, and partial shade. The Garden Must Haves range has polycarbonate or fabric roofs that keep rain and UV off completely. Choose open iron for cottage-garden character, or hard-roof aluminium if you want a usable outdoor room in all weathers.
Climbing roses, wisteria, clematis, and honeysuckle all thrive on iron gazebos. David Austin rambling roses (like 'The Generous Gardener' or 'Malvern Hills') are ideal — they have flexible canes that weave through metalwork naturally. Wisteria creates dramatic spring displays but needs sturdy pruning. For quick coverage in the first year, plant sweet peas as annuals while waiting for perennial climbers to establish. Avoid ivy — it's too aggressive and the aerial roots can trap moisture against the metalwork.
Our metal gazebos range from £219 to £1,499. The Heritage Arbour Bench and Lattice Arch start at £219. Mid-range open iron gazebos like the Vienne Square (£369), Cockerell (£545), and Regal (£665) suit most gardens. The modern aluminium Pandora range starts at £499 for a 3x3m footprint. Premium pieces include the Gothic tunnels (£1,145-£1,150) and the Avignon with full canopy (£1,499). Free UK delivery is included on all orders.
