Neptunus

What Neptunus does

Neptunus is a Dutch-headquartered, family-owned specialist in temporary structures, founded in 1937 by Anton Eilers. The company designs, manufactures, hires, sells, and installs marquees, event structures, and semi-permanent buildings for commerce and industry across seven European countries — the Netherlands (Kessel HQ and production), UK (Northampton), Belgium, Germany, Austria, France, and Poland (manufacturing in Wrocław), with additional service coverage into Switzerland.

Its core technology centers on aluminium space-frame construction, with proprietary hydraulic roof-lifting systems, a Flexolution modular bolt-together system, insulated sandwich panels, and a portfolio that includes the world's first double and triple-deck temporary structures. The product range spans two business lines: temporary buildings (Evolution and Flexolution series, used for retail, sports halls, showrooms, warehouses, education, and emergency triage) and event structures (Alu Hall, Alure, Alure Globe family, Salacia, Cathedral, Poseidon, pagoda marquees, and multi-deck options for festivals, corporate events, and high-end hospitality). Lifespans range from a few months up to 20 years, and components are designed to be reusable and recyclable.

Commercially, Neptunus operates a hybrid model: rental/hire on a project basis, direct product sales to owners, and full turnkey solutions covering design, build, installation, and dismantling. It sells directly through seven national subsidiaries with localized sales teams and dedicated project managers, targeting enterprise clients including Tomorrowland, Pinkpop Festival, McLaren, Audi, McDonald's, the LTA, and major European retailers. Marketing is multi-channel with five-language websites and an active social and case-study presence, while revenue is not publicly disclosed.

The temporary buildings segment includes the Evolution series (with Evolution I, II, III variants) featuring hydraulic space-frame roof technology for rapid assembly, and the Flexolution series (Flexolution II and III) offering fully modular, demountable construction for retail, showroom, classroom, and office applications. The event structures portfolio is extensive, featuring: Alu Hall structures (Alu Hall, Alure, Alure Globe, Alure Globe Giant, Alure Globe Dome, Apollo, Apollonia, Alu Pergola, Galeria, Ocean) for exhibitions, conferences, hospitality, and festivals; Multi-Deck Structures providing double and triple-storey options with various roof designs; Pagoda Structures including Mercury & Saturn Marquees and Pluto, Mars & Jupiter Event Tents for smaller-scale events; and specialty structures such as Salacia (circular floating structure), Cathedral (wood and steel construction), Poseidon, and Mezzanine (elevated floor systems). The products range from basic no-frills tents to high-end sophisticated structures, all designed to be reusable and demountable with lifespans from months to 20 years.

Scale indicators7 records

Recent moves6 records

Expansion highlights6 records

Broad incumbents

• GL events: French-listed global event services group providing temporary structures, event overlay, and venue management across exhibitions, sports, and festivals. Directly comparable as a broader incumbent in the same temporary-structure space Neptunus addresses, but at much greater scale and geographic reach.
• Algeco: Major European modular space provider (portable cabins, modular buildings) serving construction, education, and commercial clients. Comparable to Neptunus's semi-permanent Flexolution line but focused more on permanent modular than event structures.

Regional players

• Wernick Group: UK provider of modular and temporary buildings for education, healthcare, construction, and events. Comparable to Neptunus's Flexolution/Evolution semi-permanent building line serving UK-based retail, sports, and education customers.
• Field & Lawn: UK marquee and temporary structure hire business serving events, weddings, and corporate clients. Comparable hire-based event-structure model in the UK, though smaller scale and narrower premium-events positioning than Neptunus.

Direct peers

• HTS tentiQ: Manufacturer and supplier of temporary and semi-permanent structures with European production and global distribution. Comparable product set (industrial tents, event halls, modular buildings) and similar focus on hire-and-sale across events and commercial segments.
• Losberger (legacy) / De Boer (legacy) tent brands: Combined entity of Losberger and De Boer shelters, a leading European temporary-structure group with manufacturing in Germany and the Netherlands. Directly competes with Neptunus across festival halls, exhibition structures, and modular semi-permanent buildings.
• Röder Zeltsysteme: German manufacturer of aluminium event tents and temporary halls serving festivals, exhibitions, and industrial clients across Europe. Comparable in technology (aluminium space frames), product range, and target customers to Neptunus's Alu Hall and Alure lines.
• Losberger De Boer: European-headquartered manufacturer and renter of temporary and semi-permanent structures for events, sports, retail, and industry. Closest direct peer to Neptunus with overlapping product portfolio (aluminium halls, multi-deck, modular buildings) and similar turnkey delivery model.
• Spaciotempo: UK and European supplier of temporary buildings and marquees for retail, sports, industrial, and event applications. Overlaps directly with Neptunus's temporary-building hire business, particularly in UK retail-replacement and sports-hall use cases.

Others

• Aggreko: Global temporary power and temperature-control provider serving events, utilities, and industry. Adjacent peer serving the same large-festival and major-event customers with complementary infrastructure (rather than competing structures).
