What Materials We Use to Build a Traditional Orangery

At Glass House Architecture, every orangery is built with longevity, comfort and character in mind. We don’t use plastic kits or pre-fab solutions. We construct each project using carefully chosen materials that suit the property and stand the test of time.

This article explains what materials we use in a traditional orangery and why they’re selected. From structural timber to glazing, brickwork, and finishing touches, everything is chosen to reflect the quality our clients expect.

Timber and Hardwood for the Frame

The frame is the heart of every orangery. We use either engineered hardwood or oak, depending on the property and the intended finish. Oak is strong and full of character. It works beautifully on listed buildings, barn conversions, and period homes. Over time, it develops a soft silver tone that suits rural settings.

For painted finishes, we use engineered hardwoods such as sapele or accoya. These are stable, moisture-resistant, and hold paint extremely well. They also allow for finer sightlines and traditional window proportions.

We do not use uPVC. It lacks strength and character, and it does not suit the quality of home we typically work with.

Brickwork and Masonry

The base of the orangery is usually built in brick or stone. We source materials to match the existing building as closely as possible.

In some cases, that means using reclaimed brick. In others, we colour-match modern handmade options. The goal is always a seamless connection between the orangery and the original property.

Compared to a full brick extension, an orangery includes more glazing and detailing, but the quality of the masonry still matters. We treat the brick base as part of the overall design.

Glazing and Performance

We use high-performance double or triple glazing in all orangeries. The specification is tailored to the room’s orientation, use and exposure.

Solar control glass helps regulate heat. Low-iron glass is used where maximum clarity is important, especially in roof lanterns. Self-cleaning coatings can also be applied to reduce maintenance.

The glass used in a traditional orangery makes a real difference to comfort. It helps manage temperature, improve efficiency, and deliver a bright space that performs well throughout the year.

Roof Structure and Roof Lanterns

Our roofs are constructed from insulated timber panels with a central glazed lantern. This design brings in natural light from above while still offering a solid, well-insulated ceiling.

The lanterns are built from hardwood or slimline aluminium, depending on the size of the opening. Glazing is specified to meet modern U-value standards and often includes solar control.

This roof format provides better comfort and daylight than a brick extension, without the excess exposure often seen in glass box designs.

Interior Finishing

Inside, we finish each orangery to the same standard as the rest of the home. That includes plastered walls, cornicing, skirting and traditional joinery.

Integrated lighting, underfloor heating and bespoke fittings are often included as standard. These accessories help turn the orangery into a year-round living space rather than just a seasonal room.

Compared to a conservatory, the finish is far more substantial and tailored.

Paintwork and Fittings

Painted orangeries are finished with microporous exterior-grade coatings that protect the timber and allow it to breathe. These coatings are long-lasting and available in any colour.

We use high-quality hardware in period-appropriate styles. That includes forged iron, aged brass and pewter window furniture. These elements are subtle but essential to the finished look.

Regulatory Standards and Compliance

All our orangeries comply with UK building regulations and are designed to meet planning permission requirements. We handle planning applications where needed and advise on what can be built under permitted development.

Listed buildings and homes in conservation areas are treated with extra care. We often use heritage materials and traditional detailing to satisfy local planning officers.

Summary of What We Use

• Oak or engineered hardwood for structure

• High-spec double or triple glazing for light and performance

• Brick or stone bases matched to the existing home

• Insulated flat roofs with glazed lanterns

• Interior finishes that match the character of the home

• Paints and fixings designed for traditional properties

  
  

Other Considerations

• The cost of a traditional orangery depends heavily on material choice.

• Orangery ideas vary, but quality materials form the foundation of every design.

• Roof types, accessories and glass specification all contribute to comfort.

• Compared to a glass box extension, a timber orangery has more warmth.

• Compared to a brick extension, it offers more daylight and charm.

• Choosing the wrong materials is one of the most common mistakes to avoid.

• Every structure is designed with the pros and cons of each material in mind.

• Planning permission is considered early, especially for conservation areas.

  
  

Final Thoughts

We believe a traditional orangery should last for decades, not just look good when it’s built. That’s why we work only with materials we trust that deliver real comfort and value.
