Design Philosophy

Why a UPVC Conservatory or Orangery Makes Sense

The old objection to conservatories—too hot in summer, too cold in winter—disappears when you use premium UPVC. Our multi-chamber profiles are precision-manufactured to achieve U-values that rival traditional masonry construction, creating a room that works twelve months of the year. Combined with advanced glazing, the result is a living space that stays comfortable without driving up energy bills.

The distinction lies in the engineering. Premium UPVC profiles are thicker, more precisely manufactured, and finished with advanced foil technology that replicates timber grain or delivers contemporary colours with absolute fidelity. Whether you choose a traditional conservatory or a flat-roofed orangery, each frame is designed to complement your property—not look like an afterthought bolted onto the back.

Conservatory vs. Orangery: Which Is Right for Your Home?

Both add valuable living space. The choice depends on your property, how you want to use the room, and the architectural character you are looking for.

UPVC Conservatory

Light-Filled & Versatile

A conservatory maximises natural light with a fully glazed roof and walls, creating a bright, airy room that connects your home with the garden. Modern UPVC conservatories with multi-chamber profiles and advanced glazing bear no resemblance to the draughty lean-tos of the past—they are comfortable, quiet, and thermally efficient living spaces.

Maximum natural light through glazed roof
Victorian, Edwardian, lean-to, and gable styles
Typically does not require planning permission
Strong connection between home and garden
Cost-effective way to add living space

UPVC Orangery

Architectural & Substantial

An orangery combines solid masonry pillars or rendered walls with a glazed lantern roof, creating a room that feels more like a permanent extension. The result is a space with greater thermal mass, reduced glare, and an architectural presence that integrates seamlessly with your existing home—particularly suited to period and traditional properties.

Solid walls with glazed lantern roof
Greater thermal mass for year-round comfort
Feels like a permanent part of the house
Suits period homes and traditional architecture
Higher perceived value and resale impact

Why Premium UPVC Outperforms Timber and Aluminium

The frame material affects thermal performance, maintenance, appearance, and cost. Here’s how premium UPVC compares for conservatory and orangery construction.

Hardwood Timber

Natural character – Authentic grain and warmth
Heritage authenticity – Preferred for listed properties
Heavy maintenance – Annual painting and repairs essential, especially on conservatory roofs
Rot risk – Conservatory joints are especially vulnerable in damp climates
Significantly higher cost – Premium timber conservatories command substantial budgets

Aluminium

Slim sightlines – Maximum glass area for panoramic views
Structural strength – Allows larger spans without intermediate supports
Thermal weakness – Conducts heat rapidly, making conservatories uncomfortable without expensive thermal breaks
Condensation risk – Cold bridging causes moisture problems in conservatory environments
Highest cost – Typically the most expensive conservatory frame option
Why Premium UPVC

Built for Year-Round Living

Multi-Chamber Profiles

Precision-manufactured profiles with multiple internal chambers trap air to create superior insulation—keeping your conservatory warm in winter and cool in summer.

Heritage Expertise

Energy Performance

U-values as low as 1.0 W/m²K mean your conservatory contributes to your home’s energy efficiency rather than undermining it. Lower bills, greater comfort.

UPVC Conservatory & Orangery FAQs

Common questions about UPVC conservatories and orangeries—materials, planning, costs, and what to expect.

Most conservatories fall under permitted development rights, meaning planning permission is not required provided they meet certain size and positioning criteria. However, if your property is in a conservation area, is listed, or the proposed conservatory exceeds permitted development limits, you will need to apply. We advise on planning requirements during your free design visit and handle applications where necessary.

Not with premium UPVC. Our multi-chamber profiles achieve U-values as low as 1.0 W/m²K, and combined with solar-control glazing and proper ventilation design, your conservatory will be comfortable year-round. The days of draughty, seasonal-only conservatories are over—modern engineering has solved the problem entirely.

A conservatory has a fully glazed roof and predominantly glazed walls, maximising natural light. An orangery combines solid walls (brick, render, or masonry pillars) with a glazed lantern roof, creating a room that feels more like a permanent extension. Orangeries offer greater thermal mass and architectural presence, while conservatories offer maximum light and garden connection. Both can be built with premium UPVC frames.

A typical UPVC conservatory takes 4–8 weeks from design approval to completion, depending on size and complexity. Orangeries generally take 8–12 weeks due to the additional masonry work. We provide a detailed timeline with your quotation and keep you informed throughout the build.

We offer an extensive range of foil finishes including authentic wood-effect options (golden oak, walnut, grey tones), pure white, anthracite, and contemporary colours. Dual-colour options are available—different colours inside and out—so you can match your external brickwork while keeping a bright white interior. Every finish is precision-applied to exacting standards.

A well-designed conservatory or orangery typically adds between 5–10% to a property’s value, and often more in terms of desirability. The key is quality of design and build—a poorly designed conservatory can actually detract from value. Our bespoke approach ensures the addition looks and feels like it belongs to the property, which is what buyers respond to.
