Anderson Architects
Conservatory Extensions in Oxfordshire
At Anderson Architects, we design conservatory extensions in Oxfordshire that balance light, comfort, and lasting quality. Moving beyond the draughty glass boxes of the past, our modern conservatories are carefully detailed architectural spaces — bright, energy-efficient, and beautifully integrated with your home.
A Contemporary Approach to the Conservatory
Today’s conservatories can do far more than provide extra space. We create designs that blur the line between house and garden, using high-performance glazing, insulation, and shading to keep spaces comfortable year-round. Each project is tailored to your home’s architecture — whether it’s a period property in Banbury, a listed cottage in the Cotswolds, or a modern home in Oxford.
Designed for Light, Comfort, and Connection
Our conservatory extensions are designed to bring natural light deep into your living spaces while improving flow and everyday use. By combining thoughtful orientation, roof glazing, and elegant structural detailing, we create spaces that feel open yet sheltered — perfect for dining, relaxing, or working.
From Planning to Completion
We guide clients through every stage of the process — from initial feasibility and planning permission to technical design and delivery. Our experience across Oxfordshire ensures that each conservatory extension meets local planning requirements and blends seamlessly with its surroundings.

Do I need planning permission for a conservatory extension in Oxfordshire?
In most cases, conservatories fall under permitted development, meaning they don’t require full planning permission. However, listed buildings, conservation areas, and properties with previous extensions often need consent. We assess this at the feasibility stage to ensure your design complies with local regulations.
How is a modern conservatory different from a traditional one?
Modern conservatories are designed as high-performance living spaces rather than seasonal rooms. Using insulated walls, roofs, and energy-efficient glazing, we create extensions that feel comfortable year-round and integrate seamlessly with your existing architecture.
Can you replace an existing conservatory with a new extension?
Yes — many clients choose to replace outdated uPVC or glass structures with a contemporary, well-insulated conservatory extension. This upgrade improves comfort, efficiency, and visual harmony with the rest of your home.
How much does a conservatory extension cost?
Costs vary depending on size, materials, and level of specification. As architects, we provide clear guidance from the outset and tailor the design to suit your budget while maintaining quality and value.
How long does the design and build process take?
A typical conservatory extension takes around 8–12 weeks to design, gain necessary approvals, and prepare for construction. The build itself often takes 8–10 weeks, depending on scope and site conditions.
Will my conservatory be usable all year round?
Yes. We design conservatory extensions with thermal efficiency in mind — incorporating insulated bases, high-performance glazing, and solar control to maintain comfort throughout the seasons.
Do you handle planning and building regulations?
Absolutely. We manage the full process — from planning and listed building consent to technical drawings and coordination with contractors — ensuring a smooth and compliant project delivery.
What areas of Oxfordshire do you cover?
We work across Oxfordshire and neighbouring regions, including Banbury, Oxford, Bicester, Chipping Norton, and the Cotswolds — offering a complete architectural service from concept to completion.
