About Hartley Botanic

Hartley Botanic has specialised in the design and construction of handmade Glasshouses and Greenhouses since 1938. Precision-engineered and built at our workshops in Greenfield, England, our range now spans seven established architectural styles, each available in a variety of sizes and configurations.

Whether from our established range or entirely bespoke, each is made to order. For almost 90 years, we've helped thousands of delighted Hartley Botanic clients, the world over. Greenhouse and Glasshouse excellence enshrined in our motto, Nulli Secundus - second to none.

Hartley Botanic - Handmade in Greenfield, England

You’ll find our workshops in the gorgeous mill town of Greenfield, England. Nearly 90 years of craft with every structure assembled entirely by hand, using precision parts still crafted using traditional, hand-operated equipment. Our skilled craftspeople cut, weld, glaze and finish every Hartley to order - nothing is taken off a shelf, nothing is rushed through a production line. Your Hartley Botanic glasshouse is handmade exclusively for you.

Our Range of Greenhouses and Glasshouses

Hartley Botanic offers seven elegant architectural styles, designed to suit your garden, whatever its character, period or scale:

Victorian Glasshouses - the classic span-roof form, tall and elegant, rich in horticultural tradition and available from intimate to imposing
Heritage Greenhouses - a timeless pitch-roof design designed to sit sympathetically within period gardens and landscapes
Modern Greenhouses & Contemporary Glasshouses - clean lines, concealed engineering and generous glazing for the contemporary garden
Lean-to Greenhouses & Glasshouses - an elegant, space-efficient option. The union of garden and wall or building
Brick-Base Greenhouses - structures raised on a traditional low brick base for added aesthetic depth
Glass to Ground Greenhouses - an inspirational light-filled form with glazing that reaches up to the sky

Every style is available in a range of sizes and colours. All are handmade to order at our Greenfield workshops.

Bespoke Greenhouse Design and Builds

Every Hartley is made to order - but our flexibility goes further than the range. For clients who need something beyond our established styles, we offer a full bespoke design and installation service. Whether a modest customisation, an additional porch, a specific length, an integrated cold frame, or something altogether more unique - your own architectural commission. Explore our Made-to-Measure Service to find out more.

From intimate planthouses to palatial Glasshouses, the defining feature of a large garden or estate, every bespoke Hartley is yours and yours alone.

Why a hartley

Built to Last: The Lifetime Guarantee

Every Hartley Botanic Greenhouse and Glasshouse comes with our 30-year lifetime guarantee. A guarantee that covers both structure and installation. Designs created not for a season or a decade, but for the life and times of your garden, and beyond.

Find out more about the Hartley lifetime guarantee.

Sustainable by Design

Hartley Botanic structures are constructed primarily from aluminium and glass, materials inherently sustainable and readily recyclable. Our aluminium is procured from a UK manufacturer holding ISO 14001 Environmental Management Certification, and all aluminium waste is recycled back into the mills to be re-smelted and repurposed.

Our ‘Low Carbon Glass’ and standard glass is UK-manufactured, with ‘Low Carbon Glass’ significantly reducing carbon emissions by ~50%, with waste glass crushed and returned to source for reuse.

We also offer a full ‘de-installation’ and ‘re-installation’ service for customers who are moving home, because a Glasshouse built for life should be able to follow you through yours.
