The Hartley Highgrow

For the serious gardener, The Hartley Highgrow Aluminium Greenhouses are spacious and offer the flexibility to choose the perfect size – allowing you to put your own personal stamp on your garden’s interior space.

Built to the classic Hartley Botanic semi-dodecagon shape, these greenhouses & glasshouses maximise the available space inside with large panes of glass and minimal metalwork in the frame itself.

This creates a professional aesthetic and offers the level of performance you might expect to go along with it, providing you with top-quality growing space for climbing plants and taller shrubs where you will love spending time both on sunny days and when it is overcast.

With Hartley greenhouses & glasshouses you can add extra indoor space to your property without having to spend more time inside your house – this lets you enjoy your garden all year round without having to brave the elements, as well as ensuring you can prepare your planting for the coming season without laying frost blankets over your beds and borders.

The Hartley Highgrow from the Hartley family of greenhouses & glasshouses is perfect for aspiring gardeners who want some extra space and at over 7′ 10″ – the highest greenhouse in the Hartley range can accommodate the tallest of gardeners.

These are truly versatile structures with their own in-built drainage to help cope with wet weather. What’s more its awning windows across the arched roof to allow for ventilation and optional roller blinds to shield against the glare of the sun. The sturdy semi-dodecagon shape ensures the structure is robust throughout extremes of temperature, wind and precipitation.

A side-sliding entrance keeps the design compact, eliminating some of the issues that a swing door can create and maximising the aperture created when the door is opened – and of course, there is no glass-to-glass or glass-to-metal contact, as all meetings of structural metalwork and glazing are protected with thermoplastic rubber to cushion the panes and increase the longevity of the greenhouse, making it a space you will come to love over the course of many years of happy planting.
