What Is A Conservatory?

A conservatory is basically a structure constructed on a property that’s usually attached to the side of a home. It’s a room as well as a greenhouse that’s constructed with the help of a wide range of materials which includes bricks, wood, glass and polycarbonate. A conservatory is typically built with a great amount of glass which enables it to offer huge amount of sun and light. During construction, the idea is always to muster sufficient sunlight for the plants while also enabling a cosy room within the structure especially during the cold months. Generally, conservatory extensions’ walls are made of over 50 percent of glass, while their roofs are usually made up of more than 75 percent glass.

Thanks to the advancement in technology, conservatories have also greatly developed over the years. They’ve significantly evolved from the usual luxury greenhouses to normal and everyday home extensions. Conservatories have also grown to become very energy-efficient while also providing super comfort to the extent that they’re now being used throughout the year. And while it’s formerly known to be an occasional room, it’s now more of a home’s extension.

Legally, conservatories are usually covered by what’s called the permitted development rights which exempts them from both planning permission and building regulations. The conditions below form the legal definition of a conservatory to differentiate it from an extension.

✓ Below 30 square metres in size

✓ Constructed at ground level

✓ Separated from the main building by external walls, doors or windows.

✓ Possesses its own stand alone heating system

✓ The glazing as well as fixed electrical fittings are in compliance with the relevant building regulations.

Modern conservatories are well insulated and have double glazing. This means that you can use them in winter, as well as in the warmer seasons. Different roof options such as a glass roof or a titled roof will allow a conservatory to become simply another room in the home.

Many conservatories fall under permitted development which means they don’t require planning permission. There are exceptions to this though, especially if you’re looking to have a large conservatory installed. Read our guide on conservatory planning permission for more information.

When you build a new wood-constructed conservatory, or any type of conservatory, you’ll need to dig a trench for the footings. You’ll need to dig to a minimum depth of 600mm and at least 300mm below your property’s damp proof course. When you dig down, you might expose obstacles such as underground pipes.

If this happens, you’ll need lintels for your wood-constructed conservatory. These are usually concrete and protect the pipes or obstructions from being crushed. You may also want to use steel mesh for additional support.

Building Regulations state that if an opening is formed in a wall, the structure above the opening needs to be supported. This will be especially relevant if you’re building a wooden lean-to conservatory. It says that there are two ways that you can use lintels to provide support.

The first way involves using a steel lintel to support both the inner and outer leaf of a cavity wall. It can then serve as a cavity tray that directs moisture from the cavity through the outer skin of the wall as well.

The second way to use lintels is to use two steel or concrete lintels. They support each leaf of a cavity wall construction. You’ll need separate thermal insulation and a cavity tray as well.

Whatever type of lintel you use, it should have a suitable bearing onto the wall at each side. If you’re not sure, speak to the manufacturer of your wood-constructed conservatory, or ask a reputable company to install it for you.

In 2002 the Government amended Building Regulations governing the replacement and installation of glazing units. For the first time, windows had to meet energy efficiency standards and tough thermal performance levels. For new window units you must have efficiency ratings of at least a level C.

Do You Need A Building Reg For A Conservatory?

If you’re planning to build a conservatory in your home, it’s only logical to consider whether or not you require a building reg for such a structure. Generally, several conservatories, summer buildings, sheds as well as outbuildings do not require building regulation approval to erect. One of the applicable rules is the fact that if they’re ( small or less than 30m2) or constructed with non combustible material, or are differentiated from structures nearby or land and don’t feature sleeping accommodation or room, then they’re not required to submit a building regulations approval application. However, it’s strongly recommended to check with your local authority before you commence the project as only they can provide the most accurate information.

Generally, conservatories should be primarily built of translucent walls and roofs, while also possessing an external type door separating them from the main building within a property. What’s more? The foundations and floors, however, can be laid in a number of ways, but you’ll have to put into consideration the conditions of the ground, trees as well as the existing drains. It’s also a wise decision to include insulation which makes the structure a lot easier to heat especially during the cold months.

Overall, conservatories are usually exempt from building regulations if the following conditions are met:

✓ If the conservatory is erected at ground level and are not up to 30 square metres in floor area.

✓ If the structure is separated from the rest of the house with an external quality walls, windows or doors

✓ If the conservatory features an independent heating system with different temperature as well as on/off controls

✓ If the glazing and electrical installations are in total compliancewith the relevant regulatory requirements.
