Our roofs are exceptionally strong and, you’ll be delighted to learn, maintenance free.
Locks & Catches
Each door and window is lockable using high-security industry-standard and insurance compliant fittings.
Door & Window Framing
All doors and windows of our garden rooms are constructed from reinforced steel and uPVC.
The sub-floors of our garden rooms are engineered to sit clear of the ground to allow air to circulate and remove any risk of rising damp.
4” wide guttering is provided as standard on all garden room buildings, helping to manage the flow of water from the roof and away from your garden room.
Wiring & Electrics
Internal electrics are fitted by our own part-p certified electricians. Included as standard are 3 x 13amp double sockets, consumer unit and lighting.
Internal walls
All our garden rooms are fitted with a durable and easy-clean melamine interior. The finish is a lightly reflective soft sheen surface, which is strong enough to hold fixings such as shelving and pictures. The melamine is UV stable – meaning it is will not discolour or bleach in direct sunlight.
Exterior walls
18mm thick Maintenance free, FSC sustainable certified Scandinavian redwood is used as the standard cladding choice for our garden rooms with alternative options available as upgrades.
We use an in-house engineered wall insulation system that is eco-friendly and A+ rated for fire safety.

Photon Wrap


Green Retreats engineer our unique wall panels from the highest standard of raw materials for a superior finish. Our highly efficient thermal insulation prevents extremes of temperature to keep you warm (or cool) all-year-round.

In every garden room we manufacture, we use a layer of PhotonWrap multifoil insulation, an air-open reflective insulating breather membrane.



The sub-floors of our garden rooms are engineered to sit clear of the ground to allow air to circulate and remove any risk of rising damp.

Constructed with 80mm polyurethane insulation sandwiched between steel sheets, which are then powder-coated on both sides for a maintenance free finish.

The interior flooring side is fitted with an underlay directly to the steel ready to be fitted with your choice of stylish flooring on top.

Our sub-floor structures are fire resistant, strong and robust; and can comfortably support over 380kg load capacity per square metre.



4” wide guttering is provided as standard on all garden room buildings, helping to manage the flow of water from the roof and away from your garden room.



The composition of our roof is a 60mm – 95mm section of high density fire resistant insulation surrounded by 2 steel plates. All weather-exposed steel elements are coated in an epoxy resin to ensure 100% weather proofing and resistance to growth of organic materials. All interior steel panels are powder-coated in a soft-sheen white finish. The roof of every building is pitched with a slight 4 degree slope from front to back, allowing water to run-off easily to the rear guttering system and down-pipe.


Standard Glazing

All doors and windows are fitted as standard with hard coated, low-e Pilkington K Optiwhite ‘extra clear’ double-glazing, which is argon filled and fitted with a Planitherm layer and Swisspacer providing superior insulation and energy efficiency.


Stippolyte Glazing

For additional privacy it is possible to switch to obscured/frosted glass as a no cost option.

What is Rockwool

Rockwool has excellent thermal and acoustic properties, and is also water repellent and resistant to high temperatures by holding the best fire classification possible (A1), whilst being far more eco-friendly as it’s constructed from natural materials.

What is PhotonWrap?
  • PhotonWrap upgrades thermal performance without the risk of condensation
  • The air-open membranes allow more water vapour to pass though than an air-closed membrane
  • We use this pioneering technology within our wall sections to ensure that your garden room is fully insulated for year-round use

We then use a 50mm thick layer of Rockwool RWA45.

The wall layers of your garden room from outside to inside:
  • A choice of either slow-grown, tanalised, pressure-treated cladding or the latest in composite external materials
  • A cavity gap designed to eliminate heat loss and house internal electrical wiring
  • A layer of PhotonWrap
  • A 50mm layer of Rockwool RWA45
  • 15mm Melamine
