LIFT YOUR LIFESTYLE TO THE NEXT LEVEL WITH LONDON ROOF GARDENS

While standard composite decking is a great improvement over traditional timber, it is fundamentally different from Millboard. Standard composites are made by mixing plastics with recycled wood fibres, whereas Millboard is entirely wood-free. We recommend Millboard as the ultimate premium choice for your roof or balcony for several key reasons:

100% Wood-Free (No Rot): Because standard composites still contain wood fibres, they can absorb moisture over time, leading to swelling or mould. Millboard is made from a polyurethane resin and mineral stone blend. It is completely impervious to water, meaning zero rot, even in the dampest UK weather.

Unrivalled Authenticity: Most composite boards are machine-extruded and can look noticeably artificial or plasticky. Millboard is hand-moulded from real oak planks and hand-coloured by craftsmen, giving your terrace the stunning, organic look of natural timber without the exhausting upkeep.

Superior Slip Resistance: Safety is paramount for elevated outdoor spaces. Millboard features a unique Lastane® top layer that provides exceptional grip—even when wet. Because it is non-porous, it also doesn’t support the slippery algae growth common on wood and standard composites.

Exceptional Stability: Traditional composites can expand and contract heavily as the temperature changes. Millboard has an incredibly low expansion rate (less than 0.1%) and is highly UV-stable, so it won’t aggressively fade, warp, or splinter in direct sunlight.

A Flawless Finish: Millboard uses an innovative hidden fixing system. The pliable surface layer actually flexes back over the screws after they are driven in, leaving a seamless finish with no visible hardware or pre-drilled holes.

You’ll probably need planning permission if you want to:

1 Build something new.
2 Make a major change to your building, such as building an extension.
3 Change the use of your building.
4 Work in a conservation area or the building is listed.

To find out if your project will require planning permission, contact your local planning authority (LPA) through your local council.

In almost all jurisdictions, you cannot legally construct or significantly modify a building without a structural engineer’s stamp of approval. They ensure that the architectural plans comply with local and national building codes. City permitting offices rely on the engineer’s licensed seal as a legal guarantee that the structure meets all safety standards.
