What is the maximum size of a conservatory without planning permission?

Planning permission is often a necessary requirement when getting a structure built onto your property, with the process taking a number of weeks and costing you more in planning fees; however, there has been recent changes in legislation that means that conservatories are now more often than not exempt from getting planning permission before installation, if they are under a certain set of dimensions.

As laid out in the government’s Planning Portal, your conservatory can apply as ‘permitted development’ if it does not exceed the following regulations:

No more than 50% of the land around the ‘original house’ can be covered by a conservatory. The definition of ‘original house’ is how the property stood on the 1st July 1948, if it was built before that date.

A conservatory or extension cannot stand higher than the highest point of your properties pre-existing roof. Extensions with two storeys also may require planning permission.

Your extension or conservatory cannot extend beyond 4 meters past the rear wall of your existing house.

Permitted development rights often do not apply to Flats, Maisonettes, Listed properties or homes within a conservation area.

How much does a brick conservatory cost?

The definitions between conservatories, orangeries and extensions can become blurred at a certain point, with the difference between a conservatory and an extension being how many percentage of the structure is being taken up by windows. For instance, a conservatory is defined if its roof is over 75% double glazing, and the walls over 50%, while a brick extension is anything underneath that.

Conservatories themselves are available with either floor-length double glazing panels, or can come fitted with a dwarf wall which allows for a sturdier structure, as well as electrics and pipework to be fitted to make the most out of the structure.

However, what if you want a conservatory that looks more like an extension? There are a couple of options, including fiddling with your conservatory design so that you can have brick columns stood at the corners of your conservatory rather than having dwarf walls; but if you are seriously looking for a brick-based structure that does not count as an extension, then an orangery may be your best bet.
Predominantly built from brick, yet still considered under planning permission to be a permitted development, an orangery is often mistaken for an extension because of their many similarities; however, they are more affordable and tend to have less brickwork than an extension. This makes them the perfect choice if you are looking for that extra bit of brickwork for your extension without compromising on the amount of natural light entering your property.

Conservatory Ideas

If you already have a conservatory, however, and are looking for a way to transform it into something that incorporates it back into the overall aesthetic of your property, then getting a replacement roof is a great way of doing that. If you have noticed that your conservatory is underperforming or is less than stellar at keeping in the heat, then there are several options available to you for brand new roofs.

Glass roofs are the best way of bringing in as much natural light into your property as possible, with a contemporary appeal that suits all kinds of properties including modern and traditional. While being made up of double glazing panels, these roofs still provide outstanding thermal insulation and are secure and long-lasting even after years of exposure to the elements.

Lantern roofs are a more modern take on glass roofs, with a design that brings back the ornate aesthetic of Renaissance Europe whilst combining it with all of the best advancements in modern double glazing technology so that they are incredibly thermally efficient, secure and high-performance. The added height given to your conservatory through this roofing option also creates the illusion of more space, as well as adding value to your property.

Solid roofs are the best way of making your conservatory or extension look more like a natural continuation of your property, rather than an afterthought you had attached after the fact. Available to come with tiles, you can have your roof match your properties pre-existing roof or have it offset it with a complementary colour. The tiles can also be chosen from natural slate or composite materials so that you get the best performance and appearance possible for you.

Does a conservatory add value to your home?

A conservatory tends to have a lifespan of around 25-30 years, with that being extended with additional maintenance such as roof or pane replacement. However, is it worth it in the long run?
Conservatories are such a popular home improvement installation option for one major reason: they can be used for anything. Their multi-purpose nature means that, once you have a conservatory, you can utilise it for pretty much any purpose.

If you work from home and are looking for a way of enjoying your garden more and get more ventilation and natural light, you can make your conservatory into an office. If you want your children to be able to freely come and go from the garden, then you can create a versatile play-space. If you simply want a quiet spot to relax and unwind during the evenings and weekends, then it is all too easy to make it into a sitting room or sun room. With our outstanding thermal insulation, you can use your conservatory all year around, as anything from a kitchen extension to a greenhouse if it should so take your fancy.
