Cheers to another great build! We supplied this 6m x 12m structure for Festival — set up on our levelled floor system with fully DDA-compliant ramps for easy access.

Robust, professional, and festival-ready. If you're planning an event and need a structure that can handle the crowds (and the weather!), get in touch.

We're proud to share that Key Structures is now an approved supplier of marquees and temporary structures at Syon Park — the London home of the Duke of Northumberland and one of the capital's most iconic event venues.

Syon is a genuinely special setting: Robert Adam interiors, 200 acres of Capability Brown landscape, and a history stretching back through the Tudors — all just minutes from Central London. It's exactly the kind of venue where every structure we build has to earn its place.

We had a first taste of that this spring, building for a wedding on the estate — and we can't wait to do more.

If you're planning a high-end wedding or event anywhere in London and want a marquee or structure that matches the occasion, we'd love to hear from you.

T. 020 8944 9633
Yes, that's a genuine London number — because we're 100% based in Central London. That gives us unparalleled access to, and knowledge of, what it takes to deliver premium temporary structures of every size safely, on time, and efficiently — making your next event the success it needs to be.

Last month's build in Trafalgar Square — a location we know inside out. Tight get-ins, fast turnarounds, no margin for error, and full compliance with the UK's strictest health and safety standards throughout. Just another day for the team.

If you've got an event on the horizon and need a reliable, local, professional temporary structure provider (we're based right here in SW19), give us a call. We're ready when you are.

Behind the scenes at Wimbledon 2026.
Key Structures Ltd was proud to deliver a fully bespoke off-site hospitality structure for IMG, creating a stunning player rest and dining area unlike anything we'd built before.
Sleek black frame with matching custom black glazing. Clear roof panels with black borders. And a genuine engineering challenge — the structure turns a full 90° bend to seamlessly connect to the house, forming one large, open-plan café and relaxation space.
Installed in 48 hours, using our self-weighted flooring system (bespoke to this build too), the result was a premium, professional environment fit for the world's best players.
A huge thank you to IMG for trusting us with such a unique brief — we can't wait to do it all again in 2027.

When the Ground Isn't Level, We Make Sure Everything Else Is. Installing a fully glazed 9x9 Pagoda at the iconic Guildhall in London for Event Concept and the Innovation Foundation is exactly the kind of challenge we relish — but the real story is what happened before a single frame went up. The Guildhall site presented a mild challenge in that it is on a slope. For most, that's a can be a problem. For Key Structures, its a daily challenge. Here's how we ensured a flawless, safe installation: Laser Levelling — We survey the site precisely before anything is built, giving us an exact, mm perfect, picture of the terrain. Self-Weighted Floor System — Our proprietary self-weighted flooring ensures a perfectly level structure, secured entirely within its own footprint — no ground fixings required. Wind Rated to 40mph — Fully engineered and tested to withstand wind loads up to 40mph, whatever the British weather throws at it. Custom Access Ramps — Working directly with our ramp suppliers, we match ramp specifications precisely to the site survey — delivering safe, seamless, level access every time. Fully Insured & Signed Off — Every installation meets the highest Health & Safety standards, fully Section 30 compliant and deployable across any London borough. The result? A stunning, fully glazed structure that looked perfect, performed perfectly and kept every guest safe. That's the Key Structures difference. For any requirements, big or small, give us a call.

Yesterday we were out in Battersea, delivering a temporary structure for event support — up and fully operational within a few hours, and back down just as fast. One of literally 100’s of 24 hour in/out jobs we do each year.

Key Structures is proud to be London’s only Central London-based marquee company, delivering round the clock using only our own highly experienced team. We don’t use agency crews, ever.

Whatever your site, whatever your surface — hard standing or grass — we’ll make it work. Every structure we deliver is fully insured, HSE compliant and safety rated as standard. And with years of experience working alongside councils across every London borough, you’re in safe hands from first call to final de-rig.

If you have a temporary structure requirement coming up, we’d love to hear from you. June is looking very busy, so if you’re planning ahead, it’s worth getting in touch sooner rather than later to avoid disappointment.

Give us a call — we’re always happy to help.

Key Structures returns to Chiswick House & Gardens for 2026

We're proud to announce the successful installation of the Garden Pavilion structure at one of West London's most prestigious event destinations — the Grade I-listed Chiswick House & Gardens.

For 2026, we've raised the bar. This year's installation features our FloorStak®-based flooring system throughout — delivering a perfectly level, structurally rated foundation across the site, with no external ballast, no ground fixings, and zero intrusive groundworks on this irreplaceable heritage landscape.

The result? A structure rated to withstand winds of up to 50mph, built to TÜV-certified standards, fully insurable, and engineered to perform across an entire season of high-footfall events.

As one of the only large-scale temporary structure specialists based entirely within the M25, technically demanding installations on sensitive sites are exactly what we do.

The Garden Pavilion is now open for corporate events, private dining, and venue hire throughout the 2026 season.
