Choosing Between a Conservatory, an Orangery and an Extension

Conservatory

A conservatory is mostly glazed: glass walls on a low brick base, with a glazed or lightweight roof. It gives you a bright room, a strong connection to the garden and, if kept separate from the house, a simpler route through building regulations.

Orangery 

An orangery has more masonry. Brick piers or solid walls frame the glazing, and the roof usually combines an insulated flat or pitched section with a glazed lantern. It feels more like a room of the house, holds temperature better, and suits kitchens, dining rooms, and year-round living spaces.

Conservatory or Orangery Extension

An extension opens the new room into the existing house, usually by removing the wall or doors between them. That is a legitimate design choice, but it changes the regulatory position. Our team at Richmond Bespoke Conservatories raises it at the start, not after the drawings are done.

What usually decides it is how you want to use the room. A garden room enjoyed on mild days has different needs from a space where you want to cook, work or eat through January.

Why the Local Climate Matters in Hampton Hill

Hampton Hill has the mild, changeable climate of south-west London: rain spread fairly evenly through the year, cool damp winters, and summers that are warm and increasingly prone to heatwaves. Conservatories feel those extremes more than any other part of the house. Summer 2022 showed how far temperatures can climb, with Heathrow, a few miles away, recording a reading above 40°C, and a poorly specified glass roof can push a room well beyond that on a sunny afternoon.

For summer heat, we combine solar-control glass, roof vents, and opening side windows with blinds or a solid insulated roof where the orientation demands it, so the room stays usable instead of becoming a store for boxes. To limit winter heat loss, we specify low-emissivity, argon-filled glazing, thermally broken frames, and insulated roof sections, so the room isn't dependent on a portable heater from November to March. Rain is handled with the right roof pitch, gutters and downpipes sized for heavy downpours, and flashings that cope with driving rain where the roof meets the house wall. Ventilation matters as much as glazing for controlling condensation, particularly in rooms used for dining, plants or drying washing.

A south-facing garden behind a terrace in the middle of Hampton Hill calls for a very different roof from a shaded, tree-lined plot near Bushy Park, which is why we don't work from a standard specification.

Materials and What They Mean for the Finished Conservatory

The choice of materials affects how a conservatory looks, performs and ages. We talk through the options on site, because the right answer depends on the house and the budget.

For frames, timber suits period homes and conservation area settings and can be painted or stained to match existing joinery, though it needs periodic maintenance. Aluminium gives slim sightlines and strength for large glazed spans, while high-quality uPVC offers good thermal performance at a lower cost. Composite and timber-aluminium frames combine a warm interior with a low-maintenance exterior. Double glazing is the minimum for the glass itself, and solar-control coatings, low-emissivity glass, laminated safety glass and self-cleaning finishes each solve a different problem, so we recommend them only where they earn their cost.

The roof has the biggest effect on year-round comfort, and the options include glass, lightweight insulated tiled roofs, and hybrids that combine solid sections with a lantern. At ground level, brick plinths and piers are chosen to match the existing house as closely as possible, which matters to both appearance and, in sensitive locations, the planning officer. Finally, bifold, sliding and French doors all work, and which suits depends on how the room connects to the garden. Good ironmongery is what keeps them working years later.

Homes, Households and How People Use Their Space

Hampton Hill is a largely residential suburb with a strong family character, supported by well-regarded primary and secondary schools in and around the area, from Hampton Hill Junior School and the junior department of Lady Eleanor Holles School to the secondary schools in Hampton, Teddington and Twickenham. The housing is a mixture of Victorian and Edwardian terraces, semi-detached homes and later infill, and many households have stretched their original floor plan to fit family life.

That shapes what people ask us for. Common briefs include a family dining room that opens onto the garden, and a home office or study for people who now work from home part of the week, with rail links from Fulwell and Hampton still within easy reach for the commute. We also design playrooms and second living spaces that keep children's activity out of the main reception rooms, as well as warm, bright rooms for older residents who want to enjoy the garden without braving the cold.

A well-designed glazed extension can also add value to a home in a borough where space is at a premium, and many owners choose to improve their homes rather than move. We don't make claims about the uplift on any particular property, but a good, well-built room that suits the house is generally a sound investment.
