The modern aluminium conservatory is a far cry from the cold, draughty PVC structures of the past. Today's thermally broken aluminium roof and wall systems deliver U-values that meet current Building Regulations, combined with slimline sight-lines that maximise the glass area and create bright, airy living spaces that are comfortable in every season.
We use advanced aluminium roof technology including the Aliver 5000+ system for premium conservatory applications and the Aliver 2000+ for versatile configurations. These thermally broken systems accept double glazed units from 24mm to 30mm, with polycarbonate options also available. Heavy-duty gutter and beam profiles enable large spans without excessive framing, and elegant glazing bars are designed to maximise the glass area while providing the structural performance needed for UK weather conditions.
Every conservatory is designed to your specific requirements — size, style, configuration and performance level. We combine our aluminium roof expertise with our extensive range of aluminium windows and doors to create fully coordinated conservatory structures where every component is engineered to work together and finished in matching colours.
From classic Victorian conservatories with decorative ridge cresting to sleek contemporary orangeries with flat roofs and lantern lights, our aluminium conservatory systems suit properties across Surrey, London and the South East. Whether you are extending a period home in Guildford or adding a garden room to a contemporary property in Esher, we design conservatories that complement your architecture and enhance your lifestyle.
Victorian Conservatory — The classic multi-faceted design with a faceted front, ornate ridge detail and elegant proportions. Our aluminium framing reproduces the traditional aesthetic with none of the maintenance demands of timber, and significantly better thermal performance than PVC.
Edwardian Conservatory — A rectangular footprint with a hipped roof, maximising usable floor space. The clean lines of aluminium framing suit the Edwardian aesthetic particularly well.
Gable-End Conservatory — A striking triangular gable at the front elevation, creating height and visual drama. Available in contemporary or decorative styles.
Lean-To / Mediterranean — A simple single-pitched roof against the house wall. Clean, contemporary and cost-effective. Available with opening vents for ventilation.
Orangery — A hybrid design combining solid insulated perimeter walls with a glazed roof — typically a flat roof with a central lantern. Creates a room that feels more like a conventional extension while retaining abundant overhead natural light.
P-Shaped and T-Shaped — Combination designs that merge two conservatory styles — for example, a Victorian front section with a lean-to rear — to create larger, more complex footprints.

Colours & Finishes
Aluminium conservatory and lean-to roof systems offer the full RAL palette — anthracite grey and white remain the most popular, with woodgrain foils available for a timber-effect finish.
Powder coating is applied to marine-grade standards with a minimum 25-year colour guarantee.
Aluminium offers several advantages over PVC for conservatories: slimmer sight-lines (maximising the glass area), greater structural strength (enabling larger spans with less framing), superior colour stability (powder-coated aluminium does not yellow, warp or discolour), longer lifespan (40+ years versus 20–25 for PVC) and a more premium aesthetic. The thermal performance of modern thermally broken aluminium is comparable to PVC.
Conservatories are exempt from Building Regulations if they are at ground level, less than 30m², separated from the house by external-quality walls, windows or doors, and have an independent heating system with separate controls. Larger conservatories or those not meeting these criteria require Building Regulations approval. We advise on the requirements during the design stage.
A typical aluminium conservatory installation takes 2–4 weeks on site, depending on size and complexity. This follows a design and fabrication period of 6–10 weeks. The base and dwarf walls (if required) are constructed by your builder before our installation begins. We coordinate the programme with your builder to ensure a smooth handover.
