Converting a Conservatory to an Orangery – A Complete Guide

If your conservatory feels too hot in summer, too cold in winter, or no longer suits your style, converting it to an orangery could be the solution. This upgrade can make the space more comfortable, energy-efficient, and integrated with the rest of your home.

Why convert a conservatory to an orangery?

Many older conservatories were built with basic glazing and lightweight frames. While they let in plenty of light, they often struggle with insulation. An orangery adds solid walls, better glazing, and a roof lantern, making it a true year-round living space.

This change can transform the room’s appearance, add property value, and make it more functional for daily use.

What is involved in a conservatory to orangery conversion?

The process depends on your existing structure. In most cases, the frames and roof are removed, while the base and foundations remain in place. Brick or stone walls are added, along with high-performance glazing and a new insulated roof with a lantern feature.

Any necessary reinforcements are made to ensure the structure meets current building regulations.

Planning permission considerations

You may not need full planning permission if the footprint and height remain the same. However, if you change the size, shape, or height significantly, or if your home is listed or in a conservation area, you will need to apply. It is best to confirm requirements with your local authority before starting work.

Design options for your new orangery

• Add bifold or sliding doors for easy garden access.

• Choose a hardwood frame for a timeless look or aluminium for a modern feel.

• Incorporate underfloor heating for consistent warmth.

• Use interior finishes that match the rest of the home for a seamless connection.

A well-designed traditional hardwood orangery can give the space elegance, durability, and better energy efficiency.

Cost of conversion

Converting a conservatory to an orangery is generally more cost-effective than building a new orangery from scratch, as existing foundations and base walls can be reused. However, costs vary depending on materials, glazing, and interior finishes.

A simple conversion might cost from £15,000 to £25,000, while a high-end rebuild could exceed £40,000.

Benefits of conversion over replacement

• Retains part of the existing structure, reducing cost.

• Improves insulation and comfort levels.

• Offers a more permanent architectural style.

• Increases property value.

Working with a specialist

Converting a conservatory is a technical project that benefits from expert planning and installation. A company experienced in both conservatories and orangeries can ensure the new structure blends perfectly with your home.

Whether you want a contemporary upgrade or a space that feels more like a glass room extension, careful design will make your orangery both functional and beautiful.

Conclusion

A conservatory to orangery conversion can revitalise your home, offering a stylish and comfortable space you can enjoy all year. By planning carefully, checking permissions, and working with skilled installers, you can make the most of your existing structure and create a room that enhances your lifestyle.
