The new �7.7m glasshouse at the RHS garden at Wisely, in Surrey, opens to the public on Friday. Outside planting was planned by designer Tom Stuart-Smith.

The tropical area is one of three temperature controlled zones at the glasshouse. Picture by Colvin and Moggridge.

The giant palms were shipped to the Surrey garden from glasshouses in Holland.

Planting began last year but the majority of the 5,000 specimens have been placed since the beginning of March.

The giant flat-pack structure has taken two years to put together on the Wisley site.

The best view of the glasshouse and the lake is from the fruit mount. Picture by Colvin and Moggridge.

The majority of the plants in the dry temperate zone, along with the rest of the glasshouse, were grown at Wisley. Picture by Colvin and Moggridge.

Visitor will be able to walk from the moist to the dry temperate zones without having to go through any doors. Picture by Colvin And Moggridge.
