EXTENSIONS & CONVERSIONS
Conservatory Extensions
Create light-filled living spaces with bespoke conservatories and orangeries designed for year-round comfort and architectural appeal.
About our conservatory extensions service
A conservatory extension offers a unique way to expand your home or commercial property by blending indoor comfort with the surrounding outdoor environment. Unlike standard house extensions that rely on solid masonry, glazed extensions and orangeries focus on maximizing natural light through expansive glass walls and lantern roofs. This service is ideal for homeowners seeking a sunroom, a vibrant new dining area, or a tranquil garden office. For commercial clients, such as boutique hotels or restaurants, a professionally designed orangery can provide an elegant transition space for guests. Our team manages the entire scope of the project, starting with the initial architectural drawings and navigating the complexities of planning permission and building regulations. Whether you are looking for a traditional Victorian style or a sleek, contemporary glass box extension, we ensure the structure is thermally efficient and structurally sound. By integrating high performance glazing and insulated foundations, we create spaces that remain usable and comfortable regardless of the British weather.

Frequently asked questions
Do I need planning permission for a conservatory?
In many cases, small conservatories fall under Permitted Development rights. However, if the extension exceeds certain height or area limits, or if your property is listed, full planning permission is required. We handle all assessments and applications to ensure your project is fully compliant with local authority regulations.
Will my conservatory extension require building control?
While many traditional conservatories are exempt, any extension that includes a solid roof, large openings into the house, or heating must comply with Building Regulations. This covers thermal insulation, glazing safety, and structural integrity. Our service includes managing all building control inspections and certifications.
How long does the construction process take?
A standard glazed conservatory usually takes between 4 to 8 weeks to build on-site. More complex orangeries or large-scale glazed extensions may take 10 to 14 weeks. This timeline includes groundworks, brickwork, frame installation, and internal finishes like electrical outlets and flooring.
Can a conservatory be used comfortably in the winter?
Modern conservatory extensions utilize Low-E glass and insulated bases to prevent heat loss. We often install underfloor heating or slimline radiators to ensure the space is functional throughout the winter. For summer comfort, we offer solar-control glass and integrated ventilation options.
Do you offer glazed extensions for commercial properties?
Yes, we provide glazed extensions for commercial clients, including restaurants, hotels, and office spaces. These projects often require higher fire safety standards and robust structural glazing, all of which we manage as part of our comprehensive commercial build service.
