Neptunus: flexible building solutions for a changing education sector

Experts in design, manufacture and installation of high-quality temporary and modular buildings for schools, colleges, and universities.

Neptunus is a family-owned business with over 85 years of experience in designing and constructing demountable buildings. With a strong presence across Europe and a dedicated UK branch, we specialise in high-quality, sustainable temporary structures that combine flexibility, speed, and durability. Our modular buildings are used for a wide variety of applications, from classrooms and lecture halls to dining spaces, social areas and sports halls.

At Neptunus, we believe space should never limit learning. That’s why our temporary buildings are designed to meet the evolving needs of students, teachers, and education facilities, while also complying with current regulations and performance standards. Whether you’re facing a sudden need for extra classrooms, undergoing a refurbishment, or planning long-term capacity expansion, Neptunus delivers fast, smart, adaptable solutions.

What we offer the education sector

Neptunus designs and builds modular classrooms and educational facilities that provide an optimal learning environment with minimal disruption. Our buildings can be installed quickly, tailored to your exact needs, and even seamlessly connected to existing structures to expand your capacity.

Whether you need a temporary solution for a few months or a longer-term facility for several years, our temporary school buildings offer all the comforts and functionalities of a permanent structure, including:

• full insulation for year-round usability
• specially developed walls for superior acoustic and thermal performance
• climate control systems
• washroom and hygiene facilities
• suspended ceilings and integrated lighting
• automatic doors and partitioning options
   

The result? A high-quality, fully operational learning space that supports both academic excellence and student wellbeing.

Fast, flexible and future-proof

Our structures are modular, meaning they can be scaled and adapted to suit your exact requirements, whether you need just one classroom or an entire temporary school building. We offer a range of widths, lengths and heights, cassette floors, or glazed window panels to maximise natural light.

From covered playgrounds and assembly halls to temporary libraries or science labs, our systems offer fast installation without compromising on comfort or performance. And because everything is demountable and reusable, you benefit from a truly sustainable building solution.

Seamless integration

One of the major advantages of a Neptunus temporary building is how easily it can integrate with your existing infrastructure. With a clean, modern design and a finish that mirrors permanent architecture, our buildings can be placed alongside or connected directly to your current premises, ensuring continuity and convenience.

This was precisely the case at Trinity College Oxford, where Neptunus delivered a dual-purpose temporary facility that blended perfectly with the historic surroundings. The structure housed both a dining area and a multifunctional space, showcasing how our solutions can work even in heritage or complex environments.

A turnkey approach

From initial consultation to design, installation and handover, Neptunus offers a complete turnkey service. We work closely with school leadership, local authorities, architects, and contractors to ensure smooth delivery, even on logistically challenging sites.

Our UK team brings local expertise backed by the strength of an international organisation. That means you benefit from tried and tested building systems, short lead times, and a professional, reliable partner who understands the unique dynamics of educational projects.
