Which Extension Style Should You Choose?

Oak Conservatory, Oak Orangery or Oak Garden Room Thinking about adding a beautiful oak-framed extension to your home, but unsure which style suits you best? Whether you’re considering a conservatory, orangery or garden room, each option brings added light, space and value. The main differences come down to roof design, glazing and the overall atmosphere of the space.

A guide to help you choose the perfect oak extension for your home.

What’s the Difference? The key distinction between these three styles lies in the roof structure and the balance between glass and timber: Conservatories: Predominantly glass, including the roof Orangeries: A blend of glazing, oak and a flat or partially tiled roof with a lantern Garden Rooms: Fully tiled, insulated pitched roofs with prominent oak features Oak Conservatories Often known as sunrooms or glass rooms, conservatories are the most recognisable style of extension. With fully glazed walls and roofs, they maximise natural light and offer uninterrupted views of your garden. While older designs could be uncomfortable in extreme temperatures, modern features like bi-fold doors, solar-control glazing and discreet heating systems now make conservatories suitable for year-round use. Traditionally built with uPVC, many homeowners are now opting for oak-framed conservatories. Oak offers a timeless, natural appearance, excellent durability, and strong eco credentials. It’s also frequently favoured by planning authorities, particularly for period or listed properties. The Orangery Originating in Renaissance Italy as a way to protect citrus trees during winter, orangeries were designed to combine warmth with natural light. Today, they offer a more balanced mix of glazing, oak framework and insulated roofing compared to conservatories. This balance helps maintain a comfortable temperature throughout the year - cool in summer and warm in winter. A defining feature of an orangery is the roof lantern (or skylight), which acts as a central focal point. It brings in overhead daylight, enhancing the sense of space and creating a bright, uplifting environment - ideal for kitchens, dining areas or living spaces.

Traditional Orangery

The traditional design features a flat roof, making it ideal for extensions beneath first-floor windows. This allows for generous ceiling heights and the potential for full-height glazing, creating a bright, open feel. With its clean lines and minimalist structure, the traditional orangery suits both modern homes and period properties looking for a contemporary touch. There are two different roof styles for traditional flat roof orangeries - one has guttering fixed to the outside of the oak fascia, the other has a hidden gutter behind the fascia.

Tiled Orangery (Mansard Style)

Also known as a mansard orangery, this design combines a flat central roof housing the lantern (if required) with pitched, tiled sides that can be matched to your existing roof. This creates a seamless transition between the extension and your home. Inside, exposed oak rafters add warmth and character, often drawing attention to the central lantern. Many homeowners enhance this feature with a statement light fixture to create a striking focal point. The lantern can be a fixed glazed system or our preferred ‘ribbon’ lantern with 300mm glazed upstand allowing top hung opening vents. The Garden Room Oak garden rooms are designed for year-round comfort, thanks to their fully tiled and insulated pitched roofs. This structure helps maintain a consistent indoor temperature, regardless of the season. A standout feature is the glazed gable end, which frames garden views beautifully while allowing natural light to flood the space. High ceilings add to the sense of openness, while optional exposed oak trusses and rafters introduce warmth and architectural interest. For a more contemporary look, hidden structural elements can also be incorporated leaving a flush plasterboard ceiling usually with oak purlins. Externally, garden rooms can be customised to blend seamlessly with your home - matching roof tiles, brickwork and roof pitch - so the extension feels like a natural continuation of the property. Choosing the Right Style Choose a conservatory if you want maximum light and a strong connection to the outdoors Opt for an orangery if you prefer a balanced, versatile living space with a striking central feature Select a garden room for a solid, fully integrated extension with year-round comfort and architectural presence Each option offers its own unique benefits - so the right choice depends on how you want to use your space and the style of your home.
