A full-size showroom. Towed by a car.

A pop-up shop lives or dies on its location, and the best locations are the ones a lorry cannot reach: an old-town square, a pedestrian street, the forecourt of a shopping centre, the promenade in summer. A module that arrives behind a passenger car on a trailer of up to 3,500 kg gross, and then stands on its own support legs, can be placed in all of them.

The front and one side are glazed showcase walls with doors. The shop is visible from across the street, the window display is the wall itself, and the doors can be run open along the glazing to move a queue past a counter, or closed for fittings. Heated, cooled and lit, it trades in whatever weather the month brings, so the season is as long as the permit.

The stock goes inside the closed module, up to 700 kg of it, along with the rails, the shelving and the till. One person opens the shop in about fifteen minutes, from 15 m² closed to 27 m² open, and closes it the same way at the end of the run. Nothing is built on site and nothing is thrown away when the pop-up ends.

For a brand testing a new city, the module is a shop that can move to a second location after a fortnight without a second fit-out. For a food or drink brand, it is a glazed kitchen or bar with a counter along the open side. The interior finish, exterior panels and signage are specified per order, so the same shell reads as a different brand each time it is reskinned.

Rental operators run the same module in the rental fit-out and let it to a different tenant each month; a brand that only needs a shop for one season hires rather than buys.

A conventional exhibition stand is built by a crew over a day, used for three, and mostly thrown away. Stella Space is towed into the hall closed, opened by one person in about fifteen minutes with no equipment, and closed again at the end of the fair. The same stand, with its interior intact, goes to the next one.

Closed, the module is 15 m² on its trailer, which is all the room it needs to be brought to its pitch. Open, it is 27 m² of finished room, glazed along the front and one side, with doors, so the stand has a real inside as well as a face to the aisle: a meeting room, a demonstration space or a display behind glass.

Halls with a floor loading limit or a low loading door, which rule out truck-based mobile units, are within reach of a trailer of up to 3,500 kg gross that a passenger car tows. On its own support legs, the module lets the trailer drive out and leave the hall, so there is no vehicle parked on the stand during the show.

Exhibits and furniture travel inside the closed shell, up to 700 kg, and the stand is heated, cooled and lit on its own account. Outdoor fairs and demonstration days get the same room without a marquee.

For fair organisers, a fleet of modules in the rental fit-out is a way to offer exhibitors a turnkey stand without a build-up period, and to place stands outdoors or in overflow areas the hall's infrastructure does not reach.

Hospitality at an outdoor event needs a room that looks better than a marquee, arrives without a crane and works in the weather the event actually gets. Stella Space open is a glazed suite of 27 m², with showcase walls along the front and one side, heated, cooled and lit, so it is a lounge rather than a shelter.

It arrives closed behind a passenger car, on a trailer of up to 3,500 kg gross, and can be placed trackside, quayside or beside a fairway — wherever the view is, and wherever a car can go. One person opens it in about fifteen minutes with no equipment. It stands on its own support legs, so the trailer drives out from under it and can bring a second unit while the first is in use.

Guests come in through the doors in the glazing, by a step or a ramp, so the entrance is step-free where it needs to be. With the doors open the suite is part of the event; with them closed it is a quiet room with the action on the other side of the glass.

Furniture, a bar counter, screens and catering equipment travel inside the closed module, up to 700 kg, and the interior finish is specified per order — timber, fabric, the sponsor's colours — so the suite reads as a designed space and not a hired tent.

For a series that moves from circuit to circuit or harbour to harbour, the same suite follows the calendar and looks the same at every round.

An activation is a short, intense use of a space: a few days in a city centre, a weekend at a festival, a launch evening on a beach. What matters is presence on arrival, a finished interior and a quick exit. Stella Space is built for exactly that cycle.

It arrives closed as 15 m² behind a passenger car and opens by 80 per cent to 27 m² in about fifteen minutes, by one person, with no equipment. The front and one side are glazed showcase walls with doors, so the product is on show from the moment the walls open, and the doors let people walk through rather than queue at a counter.

Rebranding it is a matter of exterior panels, interior finish and signage, all specified per order. For an agency, one module is a season of different clients; for a brand, it is a space that photographs like a flagship and moves like a trailer. The demonstration kit, the samples and the screens travel inside the closed module, up to 700 kg.

Heating, cooling and lighting mean a launch evening runs into the night and a festival weekend survives the rain that would end a gazebo. On its own support legs, the module frees the trailer to leave the site, so nothing but the room is in the picture.

Agencies that run several campaigns a year keep a module in the rental fit-out and reskin it between clients; a brand with a launch calendar of its own buys in the showcase fit-out.

Not every use is a brand. A screening unit, a temporary information point, a site office for a construction project or a production office on location all need the same thing: an enclosed room with heating, lighting and level access, delivered without heavy transport. Stella Space in the utility fit-out is specified for function rather than finish.

It is towed closed behind a passenger car on a trailer of up to 3,500 kg gross, so a council or a contractor moves it with a vehicle it already has. One person opens it in about fifteen minutes with no equipment, from 15 m² closed to 27 m² of heated, cooled and lit room. It stands on its own support legs, the trailer drives out, and the module stays on site for a week or a season.

For a public service, step-free access is the point: a ramp for wheelchairs and pushchairs, doors in the glazed front and side, and daylight in the room. A screening unit or an advice point is visible from across the square and easy to walk into, which a converted van is not.

Equipment travels inside the closed module, up to 700 kg: desks, examination furniture, screens, filing. The interior finish is specified per order — hard-wearing surfaces for a clinic, a plan table and lockers for a site office, a quiet fitted room for a production office.

Where a service moves on a rota — a different neighbourhood each week, a different site each phase — the same module follows it, and the trailer is only needed on moving day.
