About Orangeries

What Makes a Room Outside Orangery Different?

An Orangery is a premium glass extension that combines the light-filled qualities of a conservatory with the structural permanence of a traditional brick extension. The defining feature is a solid insulated perimeter roof with a central glazed lantern, which floods the room with natural overhead light while providing substantially better thermal performance.

What sets a Room Outside Orangery apart is the level of design and integration. Every project is individually designed around your home’s architecture, with options including brick or rendered pillars, internal pelmet lighting, and premium UPVC, timber or aluminium frames.

We have been designing and installing Orangeries across England — including West Sussex, East Sussex, Surrey, Hampshire, Kent, Essex, Greater London, Berkshire and Dorset — since 1973.

Why Room Outside

Why Choose Room Outside for Your Orangery?

Four things we do differently that homeowners consistently value.

Individually Designed

Every Orangery is designed specifically around your home’s architecture, your proportions and how you want to use the space. No templates, no off-the-shelf products.

A++ Thermal Performance

Solid insulated perimeter roofs combined with premium glazing are designed to achieve an A++ thermal rating — keeping your Orangery comfortable year-round while helping to reduce energy bills.

Three Material Choices

Choose from hardwood timber for period character, aluminium for contemporary slim lines, or premium UPVC for lasting low-maintenance performance. All individually specified.

Full Project Management

We handle everything — design, planning, building regulations, groundworks, installation and finishing. Over 50 years of experience across England — including West Sussex, East Sussex, Surrey, Hampshire, Kent, Essex, Greater London, Berkshire and Dorset.

Orangery Features and Options

Every Room Outside Orangery is individually designed. Choose from these premium features to create an extension that works exactly the way you need it to.

Lantern Roof

The central glazed lantern floods the room with natural overhead light. Individually sized with optional New Generation Glass.

Solid Perimeter Roof

Insulated perimeter sections deliver superior thermal performance and give the Orangery its distinctive architectural weight.

Brick or Rendered Pillars

Optional pillars add structural presence, matched to your existing brickwork or finished in a complementary render.

New Generation Glass

Designed to help block up to 80% of solar heat while maintaining natural light. Comfortable in summer, warm in winter.

Timber, Aluminium or Premium UPVC?

The material you choose affects how your Orangery looks, performs and what maintenance it needs. Here is an honest comparison.

Hardwood Timber

Natural warmth, depth and craftsmanship. Ideal for period properties — Georgian, Victorian, Edwardian and country homes. We use oak, sapele and accoya for durability. Requires periodic maintenance every 5–8 years.

Natural warmth and depth
Excellent thermal insulation
Best for period homes

Aluminium

Slimmest frames available, maximising glass area and sightlines. Perfect for modern, contemporary or minimalist properties. Virtually maintenance-free and available in a wide range of powder-coated RAL colours.

Slimmest frames, most glass
Virtually zero maintenance
Best for modern homes

Premium UPVC

Strong thermal efficiency, consistent colour retention and finishes including convincing woodgrain effects. Effectively zero maintenance — no repainting or oiling. A refined, bespoke result with long-term ease of ownership.

Orangery FAQs

Answers to the questions we are asked most often by homeowners considering an Orangery project.

A bespoke Orangery from Room Outside typically costs from £35,000 to £80,000+, depending on size, materials, complexity and site requirements. We provide a detailed quotation after a free home visit.

An Orangery has a solid insulated perimeter roof with a central glazed lantern, optional brick pillars and a more permanent architectural feel. A conservatory has a fully glazed roof. Orangeries generally cost 20–40% more but feel more like a natural extension of the house.

Many Orangeries fall under Permitted Development Rights. However, rules differ for conservation areas and listed buildings. We check this during the initial home visit and manage any applications needed.

Orangeries are generally warmer thanks to their solid insulated perimeter roof. With the right specification, an Orangery can achieve an A++ thermal rating.

A typical Orangery project takes 10 to 14 weeks from confirmed order to completion. We set out a clear timeline at the quotation stage.

Depending on product and location, we offer up to a 10-year structural guarantee backed by independent UK insurers, alongside separate product-specific warranties.
