Conservatory Extension Cost
Adding a Conservatory as an extension to your home
With house prices on the rise again, many are stuck with their current property for the time being, despite the fact they have may have outgrown it and need more space. Homeowners are therefore choosing to extend rather than move for additional space, and a conservatory is one of the most popular ways of doing this. Even though the cost of building an extension can be significant, if done professionally it will always add value to your home. Many conservatories can be constructed without building regulation approval, but it is always best to speak with your local building control team before planning any work.
Typical Conservatory Costs
Things to consider when adding a conservatory
You need to be aware that neighbours may attempt to block your conservatory plans by claiming they have a legal right to light to their windows. This right does, in fact, exist in law and overrides any planning permission you might have and your permitted development rights, but it is only relevant in certain circumstances. It does not mean that your conservatory cannot reduce the amount of sunlight entering a neighbours window, as long whatever light is reasonably required for the use of the neighbour’s property remains. This is a problem that generally only affects properties in city centres or other areas where buildings are very close together. If you suspect this right may be a problem with your extension plans, then you need to contact a specialist lawyer.
The legal minimum ceiling height has now been removed from Building Regulations, but there is still obviously a practical minimum height which this is especially worth thinking about in a conservatory build on a bungalow. Rooms should normally have a floor to ceiling height of at least 2.1m, in an extension with sloping ceilings, a minimum of 50% of the floor area should have this ceiling height. This can be difficult with single storey buildings due to the typical design of conservatories.
Many home insurance providers do not cover the building while you are changing the structure by building an extension or doing a renovation. Therefore, when carrying out the building works, you need to have site insurance to cover the existing structure and the conservatory until you complete the build, at which point you should notify your insurance company and ensure the existing cover is sufficient. Builders will often claim they have insurance in place but they may simply mean liability cover, which will not cover fire, flood and storm damage.
When planning a conservatory, one of the most important aspects is deciding on the most efficient and practical access to the extension, using an existing room for access rarely works out well unless the room is very large, otherwise the room used for access becomes simply a corridor and you end up sacrificing one room to gain another!
Doing it Yourself
Building your own conservatory extension can save you a significant amount of money. Most conservatory kits are fairly easy to assemble if you are a DIY enthusiast with average DIY ability. However, a poorly built conservatory will more than likely adversely affect the property value and could be dangerous and even cause problems with the existing structure if badly fitted. If you are less than confident in your DIY skills but still want to save some money, you can always ask a builder to take care of the foundations and build the base for you. You could then assemble the conservatory and get the builder to fit the conservatory to the base and connect to the existing building for you, and still save money.
If you are determined to build the conservatory as a DIY project, you first need to check that your proposed extension does not require consent or permissions. Then you need to choose a size and type of conservatory which not only works well with the available space, but is simple enough for you to build. Most conservatory kits come with all frames, roof, glazing and external sills, along with a fitting kit with sealant, masonry fixings and self-tapping screws. However, the interior finish is usually all down to you, so be sure to budget for that.
Building a conservatory does require a good level of DIY experience, or the assistance of someone with such experience. A typical conservatory will also take around 3-4 days for two men to complete (and that’s assuming you know what you are doing and there are no major problems). However, once complete, you can enjoy your new extension in the knowledge that you have saved yourself many thousands of pounds!
