Aluminium Conservatories & Orangeries
Slim-Line Profiles • NGG Glass • Year-Round Comfort
Aluminium gives you what other materials cannot: the slimmest possible frames with the greatest structural strength. Our bespoke aluminium conservatories and orangeries use British-manufactured profiles and NGG high-performance glass to create rooms that stay comfortable every day of the year.
Why Aluminium Is the Architect’s Choice for Conservatories
Aluminium does what timber and UPVC cannot: it holds structural loads with the slimmest possible profiles, maximising your glass area and your views. Our slim-line aluminium frames are precision-engineered in Britain, powder-coated to AAMA standards, and designed to last decades without painting, staining, or seasonal maintenance.
Every conservatory and orangery features our NGG (New Generation Glass)—specialist climate-responsive glazing with advanced low-E coatings and argon gas insulation. The result is a room that stays cool in summer and warm in winter, not a seasonal space you avoid for half the year.
Aluminium Conservatory vs. Orangery vs. Glass Extension
All three use the same aluminium craftsmanship and NGG glass. The choice depends on how you want the space to look, feel, and integrate with your home.
Aluminium Conservatory
Maximum Light & Views
A fully glazed roof and walls flood the room with natural light. Ultra-slim aluminium profiles maximise the glass area, creating an open, airy space with strong visual connection to the garden. NGG glass prevents overheating in summer and heat loss in winter.
Aluminium Orangery
Architectural Presence
Solid insulated perimeter walls with a central glass lantern create a room that feels more like a permanent extension. Greater thermal mass reduces temperature swings, and the substantial architectural presence integrates seamlessly with traditional and contemporary properties alike.
Aluminium vs. UPVC vs. Timber for Conservatories
The frame material shapes everything—sightlines, thermal performance, maintenance, and how the room ages. Here is how aluminium compares.

How Homeowners Use Aluminium Conservatories & Orangeries
Every project starts with how you want to live. Here is how homeowners have used aluminium to add space and value to their homes.
Open-Plan Kitchen & Dining Extension
An aluminium-framed orangery with a glass lantern roof transformed a cramped kitchen into a bright, open-plan kitchen-diner. The NGG roof glass keeps the space comfortable even on the hottest summer days, and the anthracite grey powder-coat complements the period brickwork.
Garden-Facing Living Space
A couple wanted to make better use of their garden views. This aluminium conservatory features floor-to-ceiling glazing with ultra-slim profiles, flooding the interior with light while providing uninterrupted views of the landscaped garden beyond.

Aluminium Conservatory & Orangery FAQs
Common questions about aluminium conservatories and orangeries—materials, performance, colours, and what to expect.
Aluminium delivers slimmer sightlines, superior structural strength, and larger span capability than UPVC. It allows more glass area for better views and more natural light. Unlike UPVC, aluminium is available in over 200 RAL colours with dual-colour options. The trade-off is cost—aluminium is a premium material, but for homeowners who prioritise views and architectural quality, it is the natural choice.
New Generation Glass (NGG) is specifically engineered for glass extensions. It uses advanced low-E coatings to reflect solar heat in summer while retaining internal warmth in winter, combined with argon gas fill and warm-edge spacer bars. The result is a conservatory that stays comfortable year-round—no blinds needed, no overheating, no cold spots.
Many conservatories fall under permitted development rights, meaning planning permission is not required. However, this depends on your property’s size, location, and listed status. If you are in a conservation area or have a listed building, additional approvals may be needed. We handle all planning checks and applications as part of our service.
We offer over 200 RAL colours, powder-coated to AAMA standards for lifelong durability. Popular choices include anthracite grey (RAL 7016), black (RAL 9005), and heritage green (RAL 6005). Dual-colour options are available—different colours inside and out—so you can match your external brickwork while keeping a contemporary finish internally.
A typical aluminium conservatory takes 8–12 weeks from design approval to completion. Orangeries generally take 10–14 weeks due to additional masonry work. The aluminium frames are precision-manufactured off-site while groundwork is prepared, which keeps the overall programme efficient. We provide a detailed timeline with your quotation.
Very little. The powder-coated aluminium finish requires no painting and will not peel, flake, or discolour for decades. A simple wash with soapy water every few months keeps the frames looking new. Unlike timber, there is no risk of rot, warping, or structural degradation. The NGG glass is also available with self-cleaning coatings if desired.
