Part of Cosy Garden Rooms Limited
School buildings
At Cosy Classrooms, we design and build calm, light-filled outdoor classrooms that provide flexible space for teaching, learning, support and activities, extending your school’s facilities without the disruption or cost of traditional building work.
Well-designed, high-quality buildings that schools can adapt to their own needs
Whether you need a teaching space, quiet study area, creative room, music room or activity space, we create bespoke buildings that work with your site, curriculum, and future plans.
Bespoke design, any shape, size, or layout
Every Cosy Classrooms building is individually designed to suit your school. There are no standard templates — the shape, size, layout, and configuration are all entirely bespoke.
You can choose from a variety of:
-
Exterior cladding options to match your setting
-
Layouts and configurations to suit teaching or support spaces
-
Placement of doors and windows for light, supervision, and access
Built for many uses
Cosy Classrooms buildings are adaptable, flexible spaces and can be used for a wide range of educational purposes, including:
-
Outdoor classrooms and mainstream teaching spaces
-
Libraries and reading areas
-
Music, art, and creative rooms
-
Meeting, staff, or breakout spaces
-
Lunch rooms or activity/exercise spaces
-
Sensory spaces (school-fit out)
-
Toilet and changing facilities
-
Intervention or nurture support spaces
Because they are separate from the main building, these spaces often feel calmer and more focused, providing environments that support both group activities and individual learning.

Our school buildings are suitable for:

Primary and secondary schools
-
Nurseries and early years settings
-
Colleges, Universities and further education establishments
-
Academies and multi-academy trusts

Independent and specialist education providers
If you need additional teaching space without the disruption of a traditional extension, an outdoor classroom can be a practical and cost-effective solution.
Building regulations guidance
Permanent buildings should comply with Building Regulations, but the requirements vary depending on size and use:
-
Small, part-time use buildings (usually under 30m²) such as support rooms, nurture spaces, or intervention areas typically do not require formal Building Regulations approval.
-
Permanent buildings intended for full-time teaching or larger in size are designed to meet Building Regulations, and Cosy Classrooms can guide schools through the approval process, working with building control and engineers to ensure compliance with fire, structural, energy, and accessibility standards.
This approach ensures schools get a space that is safe, practical, and fit for purpose, whether for part-time support use or full-time classroom teaching.
"We’ve created a space that truly meets our needs, its open, flexible and inspiring. It’s everything we hoped for and more. "

Flexible by design — grows with your school
One of the key strengths of a bespoke Cosy Classrooms building is flexibility. A space doesn’t need to be fixed in purpose — it can evolve as your school’s requirements change over time:
-
A music room today could become a library tomorrow
-
An intervention space could serve as a staff room next year
-
A quiet study area might grow into an activity space
This adaptability makes these buildings a long-lasting investment in your school’s future.
Advantages over traditional extensions
Unlike a traditional extension that involves months of disruptive construction, a bespoke outdoor school building:
-
Is designed to fit your space and uses
-
Can be configured around trees, levels, and site constraints
-
Maximises available outdoor space
-
Adds useful capacity without major disruption
These buildings are permanent, insulated, and suitable for year-round use, offering a practical alternative to costly, intrusive building work.
