Is an orangery better than a conservatory?

For year-round use, generally yes. Orangeries are warmer in winter and cooler in summer due to solid walls and better insulation. They also look more integrated with the house and add more value. Conservatories are cheaper but can be uncomfortable in extreme temperatures.

How much does an orangery cost?

From £30,000 for a small (12–16m²) orangery to £100,000 for a large (25–35m²) design. This is more than a conservatory (£10,000–£30,000) but less than a full brick extension of the same size.

Do I need planning permission for an orangery?

Usually not. Most orangeries fall under Permitted Development. The same PD rules as single-storey extensions apply. If your property is in a conservation area, an orangery's solid walls are often more acceptable than a glazed conservatory.

Does an orangery need Building Regulations?

If less than 75% of the roof is glazed (which is the case for most orangeries), Building Regulations apply in full. This means foundations, insulation, drainage, and electrical work must comply — same as a standard extension.

Q: Do I need planning permission for a orangery vs conservatory: complete guide in Wimborne?

It depends on your specific property. Dorset Council covers a large rural area with many villages in conservation areas and AONBs (Dorset AONB, Cranborne Chase AONB). Permitted Development rights may be restricted in these areas — always check before assuming PD applies. Dorset Council approves approximately ~87% of householder applications. We assess your project and property designations before recommending the planning route — many Wimborne homeowners find they only need a Certificate of Lawfulness (£1,500).

An orangery sits between a conservatory and a full extension. It has solid walls with large windows and a flat roof with a central lantern — giving it more presence and year-round usability than a conservatory, at a lower cost than a brick-built extension. Here is what Wimborne homeowners — covered by Dorset Council — need to know about costs, planning, and timelines.

What you need to know

Orangery vs conservatory vs extension

A conservatory is mostly glass (75%+ glazed roof and walls). An orangery has solid brick or rendered walls with large windows and a flat roof with a glazed lantern. A full extension is entirely solid construction. Orangeries look more substantial than conservatories and are warmer in winter and cooler in summer.

Design and materials

Modern orangeries typically use brick or rendered columns with aluminium bi-fold doors and a flat roof with a central roof lantern. The solid perimeter walls allow for better insulation than a conservatory, making the space comfortable year-round without excessive heating costs.

Planning permission in Wimborne

Orangeries usually fall under Permitted Development as they are structurally similar to a single-storey extension. Standard PD rules apply — 4m/8m depth limits, height restrictions, and boundary conditions. In conservation areas, the solid walls and flat roof are often more acceptable than a glazed conservatory.

Standard single-storey extension PD rules apply. The 75% glazed roof rule that distinguishes conservatories from extensions under Building Regulations does not affect PD — it affects whether Building Regulations apply.

Dorset Council — local planning context

Dorset Council covers a large rural area with many villages in conservation areas and AONBs (Dorset AONB, Cranborne Chase AONB). Permitted Development rights may be restricted in these areas — always check before assuming PD applies.

Dorset Council processes approximately ~6,000 planning applications per year, with an approval rate of ~87%. Average decision time is 8–10 weeks.

Building regulations

If less than 75% of the roof and 50% of the walls are glazed, Building Regulations apply in full (same as a standard extension). Most orangeries fall into this category. If the glazing thresholds are exceeded, a thermal separation (door between house and orangery) may be required.
