Third Space
A members-only luxury health and lifestyle group, operating premium clubs across London
A brand, web and mobile app rebuild designed to turn Third Space's website and digital presence into its best salesperson. Plug & Play were tasked with massively increasing subscriptions and market penetration for Third Space.
Third Space is expanding rapidly, opening new locations on an ambitious rollout schedule, and needed its digital presence to keep pace with that growth and drive membership subscriptions. The primary goal was to make the website Third Space's best sales person; driving new target audience enquiries that actually became paying members, upselling services like Personal Training and Spa Treatments, and doing all of it at a standard of polish that matched the in-club experience of a luxury brand.
That ambition extended beyond a single website: Third Space needed a Mobile App to work as part of the same omni-channel transformation, serving different audiences, members across multiple membership types, and PTs, whose day-to-day needs differ.
Plug & Play combined digital strategy with enterprise web development from the outset, rebuilding Third Space's website architecture and user journeys around actions that actually matter commercially, enquiries, sign-ups and service upsells. Custom map and location functionality was built specifically to support Third Space's expansion, so that every new club launch could be absorbed by the platform rather than requiring bespoke work each time.
The same strategic approach extended to mobile: rather than building one app for every audience, Plug & Play delivered two distinct apps, one for members and one for PTs, unified by a single design system, so Third Space's brand felt consistent everywhere, even where the underlying product experience had to differ.
Plug & Play curated optimised user journeys with high-quality experiences across mobile, tablet and desktop. Booking and enquiry flows were rebuilt around a single, frictionless screen that surfaces rates and key information without extra clicks. Front-end performance and enterprise CMS architecture were built for consistency across every device, with code optimised for rapid load times, critical for a luxury brand where the experience has to feel as considered on mobile as it does on desktop.
The centrepiece of the rebuild was a reimagined ‘Find My Club’ experience, built to support Third Space’s ambitious rollout of new clubs: an interactive map search with visual previews, letting users browse by location or filter by specific facility. Each location page was individually optimised for search engines, so new clubs opening during the engagement could land users directly on the right page from day one, turning Third Space’s expansion into a digital asset.
Third Space's members and its PTs use the platform in different ways, Plug & Play built two dedicated apps: a member app spanning multiple membership types, and a separate PT app built around how trainers actually manage their day. Both draw on the same underlying design system and data, keeping the Third Space brand consistent across every touchpoint without asking either audience to work around the other's needs.
The member app was built to match and extend everything available on the website: a dashboard and rewards hubs, class timetables, and booking, workout, nutrition and memebership packs, all rebuilt nativley for mobile. Beyond parity, the app carries features that exist nowhere else in Third Space's digital estate, feeding directly into the loyalty and community goals that only make sense on a device members carry with them every day.
Performance gamification sat at the centre of the app's priority list, as a mechanism for the metric enterprise buyers actually care about: retention. Turning workout performance into visible, rewarding progress gives members a reason to open the app between visits, not just before booking one, extending the relationship beyond the walls of the club.
Every screen, on web or in either app, draws from the same design system. Web and mobile app each lean into what the platform does best, while staying instantly recognisable as Third Space wherever a user encounters it, a brand that feels consistent.
A digital experience built to match the standard of Third Space's in-club service, spaning a rebuilt website structure, a member app and streamlined user journeys that make it easier for visitors to enquire, convert and become members, on a platform built to scale with Third Space's continued expansion, lifting market penetration through a website and app designed, for the first time, to do the selling itself.
That consistency extends Third Space's reach beyond the point of sign-ups, gives members a reason to open the app between visits, supports Personal Training and Spa Treatment upsells the platform was built to drive, and gives Third Space's own team infrastructure reliable enough to run the next stage of the group's rapid expansion on.
