Village gardens and the room that suits them
Many houses on the lanes around the green have long rear gardens that back onto open Green Belt land, which is ideal for a garden room facing the view. Older cottages tend to have low eaves, so a lean-to conservatory with a shallow pitch often slips neatly beneath the first-floor windows. Detached family homes towards Moneyrow Green and Stud Green usually have space for a larger plan with a dining area.
Shapes and styles
- Victorian: a faceted bay front and a steep ridged roof, a pretty match for period brick. See our Victorian conservatories.
- Edwardian: square or rectangular, giving the most usable floor for furniture. See our Edwardian conservatories.
- Regency and Elizabethan: variations on the classic forms with different roof pitches and detailing, which we can sketch on your own elevation.
- Gable-fronted: a full-height glazed front that lifts the ceiling and pulls in more daylight.
- Combination plans: L-shaped conservatories wrap around a corner, T-shaped conservatories push a central section into the garden, and P-shaped conservatories join a lean-to run to a rounded end for separate sitting and dining zones.
A small conservatory makes a quiet reading spot off a kitchen, while a large conservatory can comfortably hold a table for six and a sofa.
Glass, polycarbonate or a solid roof
For the brightest room, glass roof conservatories use sealed units, and solar-control glass helps on a south-facing plot. Polycarbonate is the lightest and simplest roof, but it is louder in rain and holds heat less well. A tiled solid roof conservatory feels more like an extension and stays warmer through winter. If an existing room is too cold to use, a replacement conservatory roof can transform it without rebuilding the walls.
Orangeries are another route, combining brick piers and a flat perimeter roof with a central roof lantern, which suits more formal houses near the green.
Getting the groundwork right
Every build sits on a properly designed foundation, and depth matters where trees are close or the soil is soft. Our page on conservatory bases explains what goes underneath and why we survey the ground first.
Do you need planning permission?
The Planning Portal treats a conservatory like any single-storey extension under permitted development. To the rear, it may project up to 3 metres beyond the original back wall of an attached house, or 4 metres for a detached one, with a maximum height of 4 metres. Within 2 metres of a boundary the eaves cannot exceed 3 metres, nothing may sit forward of the principal elevation, and all extensions together must cover no more than half the land around the original house. Outside designated land, prior approval can allow up to 6 or 8 metres.
Holyport is a conservation area, which counts as designated land, so a side conservatory there needs planning permission and the larger rear allowance does not apply. Check with the Royal Borough of Windsor and Maidenhead first, and read our guide to planning permission for conservatories and porches.
Building Regulations normally do not apply if the conservatory is single storey at ground level, under 30 square metres, separated from the house by external-quality walls, doors or windows, and heated independently with its own controls, provided its glazing and any fixed electrics comply. Cutting a fresh opening through the house wall is a different matter and does need approval.
Finishes and garden doors
Frames come in white, woodgrain foils or dual colour, with one shade outside and another inside. For the way out to the lawn, pick French doors, a sliding patio door or an aluminium bifold from the Smart Visofold or Cortizo ranges. Blinds help control glare in summer.
A porch for the front
Many cottages have a front door opening straight into the living room, and a small porch adds a buffer against the weather. Under permitted development a porch can be up to 3 square metres in floor area and 3 metres high, provided no part is within 2 metres of a boundary with a highway.
What it costs and what happens next
Size, roof and finish all affect the figure, as our conservatory cost guide explains, and we quote only after a site visit. Browse the full range on our conservatories page.

Frequently asked questions
Can I build a conservatory in the Holyport conservation area without planning permission?
A modest rear conservatory may still fall within permitted development, but conservation areas are designated land, so side conservatories need permission and the larger prior approval route is not available. Rules on listed buildings are stricter again. Check with the Royal Borough of Windsor and Maidenhead before ordering, and we can provide drawings for any application.
Which roof is best for a conservatory facing open fields?
If the view is the point, a glass roof with solar-control units keeps the room bright while limiting summer heat. If you want the room usable all year with fewer temperature swings, a solid tiled roof is warmer and quieter. Many owners compromise with a solid roof plus a glazed lantern or roof windows.
Will a lean-to fit under the low eaves of my cottage?
Usually, yes. A lean-to can be built with a shallow roof pitch so the frame stays below first-floor windows and the existing gutter line. We measure the eaves height on the survey and draw the roof to suit. Where the eaves are very low, a flatter solid roof can be the neater answer.
Can you replace the roof on my old Holyport conservatory?
Yes. If the frames and base are sound, swapping a tired polycarbonate or glass roof for a solid tiled roof or modern glass can make the room comfortable again. We check the walls, base and frames first, because a new heavier roof needs a structure capable of carrying it.
How long does a conservatory build take?
Lead times begin at 10 days for many products, but a conservatory involves groundwork, a dwarf wall and roof work, so the full programme depends on size and roof type. We give a realistic timetable after the survey. With our workshop around a mile from Holyport, the team can be on site early each day.
