Planning a bespoke orangery extension can feel daunting, but with a clear, step‑by‑step construction process it becomes an exciting upgrade for your home. In the UK, homeowners increasingly choose brick and glass Orangery extensions over basic conservatories because they offer better insulation, more architectural character and a stronger connection to the garden.
Every successful orangery construction process starts with a clear brief. Decide whether you want an open‑plan kitchen orangery extension, a bright family room, a garden‑view dining space or a hybrid orangery‑conservatory living area. Think about how many people will use the room, what time of day it will be busiest, and how it should link to your existing layout.
At this stage, set an approximate budget range and list key features such as roof lanterns, bi‑fold doors or feature glazing. A specialist like Farrow Jones can then shape a bespoke orangery design that suits your home and expectations (visit farrowjones.com to start the conversation).
Next comes a detailed site survey. The team will measure your existing walls, openings, garden levels and boundaries, and assess drainage and access. These measurements feed into concept drawings that show how the orangery extension will attach to your property and how light will move through the space.
You will then review floor plans and elevations, usually with options for different orangery roof lantern sizes, door styles and window configurations. This is where your orangery starts to feel real, and you can fine‑tune details before any permissions or construction work begin.
In many UK cases, a modest orangery can be built under permitted development, but larger orangeries, properties in conservation areas or homes with previous extensions may need full planning permission. Your orangery builder should advise you and, ideally, handle applications on your behalf.
Regardless of planning, building regulations approval is required to ensure your Bespoke orangery meets structural, insulation, glazing and safety standards. This is essential for year‑round comfort and future resale value.
Once approvals are in place, the on‑site orangery construction process begins with groundworks. Builders set out the footprint, excavate trenches, pour concrete foundations and adjust drainage where needed. These foundations are critical for long‑term stability and help prevent cracking or movement.
At this point, service routes for electrics, heating and water can also be planned so they are neatly integrated into the new orangery extension.
With foundations complete, the walls and structural elements go up. Brick or stone is usually chosen to match your existing house, helping the orangery feel like a natural addition rather than a bolt‑on conservatory. Structural openings are formed between the old and new spaces, often using steelwork to create wide, open‑plan connections.
The roof is then constructed, combining a flat or gently sloped perimeter with one or more glazed roof lanterns. High‑performance glass in both the roof and vertical frames helps keep your UK orangery comfortable in all seasons.
Next, windows and doors are installed. Many homeowners opt for slim‑frame aluminium bi‑fold or sliding doors for a contemporary orangery look, or French doors for a more traditional style. Once the structure is weather‑tight, external detailing such as coping stones, gutters and cornices is completed.
From the outside, your brick and glass orangery now looks like a finished part of the property, with conservatory‑style light and extension‑level solidity.
Inside, trades complete insulation, first‑fix electrics and plumbing, followed by plastering. Underfloor heating, flooring, lighting and, where relevant, kitchen units are installed to turn the structure into a fully functioning room.
After final snagging and cleaning, your orangery is handed over, ready to furnish and enjoy. Working with a UK specialist like Farrow Jones ensures every stage – from design to completion—is managed carefully, leaving you with a luxury orangery extension that transforms how you live.
