Garden rooms

More room, more light, more garden

Conservatories, orangeries, replacement roofs and roof lanterns, designed around how you live and built to be used in every season.

A conservatory furnished as a sitting room, with a glass roof and views of the garden

Room to breathe

The room you will use the most

A well-designed garden room becomes the place everyone ends up: breakfast in the sun, homework at the table, a quiet chair with the doors open. A badly designed one is a greenhouse in July and a fridge in January.

The difference is in the glass, the roof and the ventilation. We design every room around its aspect and how you plan to use it, so it is comfortable all year, not just on the two weekends it suits.

  • Solar-control glass and solid roof options
  • Designed and built as one project
  • Planning and Building Regulations handled for you
  • Existing conservatory? We can replace just the roof

Which is which

Conservatory or orangery?

The line between them has blurred, but the feel of the finished room is quite different.

The roof matters most

Three kinds of roof

More than anything else, the roof decides how comfortable the room will be.

Solar-control glass

Reflects much of the sun's heat in summer and holds warmth in winter, while keeping the sky overhead. Self-cleaning coatings are available.

Solid tiled roof

A lightweight insulated roof with a plastered ceiling. Turns a conservatory into a year-round room, with roof windows where you want daylight.

Roof lantern

A slim aluminium lantern set in a flat roof floods the room below with light. The centrepiece of an orangery or kitchen extension.

How a project runs

One team, start to finish

A garden room involves groundwork, brickwork, glazing, roofing and finishing. We manage all of it.

  1. 01

    Design visit

    We look at the house and garden, talk through how you want to use the room, and sketch out the options.

  2. 02

    Drawings and price

    You receive a drawing and a fixed, itemised price covering the base, frames, roof and finishing.

  3. 03

    Permissions

    We check whether planning permission or Building Regulations approval is needed, and handle the applications.

  4. 04

    Build

    Base and brickwork first, then frames and roof, then electrics, plastering and flooring as agreed.
