Our key


Insulation and heating

Your outdoor classroom is designed for use all-year-round. We provide you with a free-standing, thermostatically controlled, oil filled radiator to ensure that you have maximum thermal comfort in those colder winter months. In addition to this, we use industry leading Kingspan insulation in all of our walls, roofs and floors ensuring maximum heat retention – keeping you warm and being better for the environment.

Door set and opening lozenge window

A beautiful and practical 2.3m sliding or French door set is provided as standard, as well as an opening lozenge window. Our bright and airy school buildings help you to be at one with nature; allowing fresh air and natural light to benefit your pupil’s concentration, energy and creativity.


All of our door and window sets and options come as standard with Pilkington K ‘extra clear’ double glazing. Yet another way we help to keep you warm, this double-glazing system allows minimum heat transfer whilst the ‘extra clear’ glass enables the freest flow of natural light to brighten your classroom.


A choice of beautiful flooring finishes are available to you as standard. With options of easy to clean laminate floors or sound deadening and comfortable carpet tiles we are sure you will love our selection.


Learn and play into the evening. In the UK we cannot guarantee natural light, even in the height of summer. We offer a selection of internal and external lights that will help reduce eye-strain and make your outdoor classroom even more practical.

Wall finish

A practical and stylish melamine wall finish is fitted as standard in all of our school buildings.
