One of the most exciting and fun projects is building an extension. Once measures have been taken, a design has been approved, plans drawn up and planning permission granted, we are ready to start.
Further are the most popular types of house extensions for you to choose the one you want:
a) Porches are usually small extensions to the front of a house, although they can be much larger and can be built to the side or back. Typical examples include simple structures of only brick walls, columns, windows and a door. More elaborated / larger versions can be bare brick or plastered and have complete electrical installation in order to get light and electric sockets.
Due to their size most porches do not require planning permission and as long as the porch is separated from the house by an internal door, and not heated, then they will not require a building certification. However, if you want electrics installed you must either have the job inspected by the building control department or use a Part P registered electrician.
b) Conservatories – Fairly simple structures that are usually made of UPVC, timber or aluminium. Some conservatories require planning permission and some do not, but the rules on building control apply as to porches.
c) Sunrooms – A sunroom is essentially a conservatory with a solid roof and walls, including plenty of glazing. They are sturdy and warm, while bringing in a lot of sunlight. Due to higher costs involved and greater complexity than a conservatory, it is advisable to employ both an architectural company and an experienced building company.
Rules for sunrooms are very similar to that of conservatories for Planning Permission. However, a building control permission will almost certainly be required.
d) Single storey extension
When you want a new room or a room extension with a vaulted ceiling that uses the pitched roof space, a single storey extension is what you need.
Single storey extensions are built onto a part of the house whereby one or more sides of the extension is attached to the property and there is only the ground floor plus any basement built to it. Single storey extensions require building control but they might not require a planning permission.
The addition of Single Storey Side Extension can add significant value to your home, and help you turn your extension in to:
The greatest considerations of this type of extension are the size of the extension, how the roof will work with the existing building/s and its impact upon neighbours. Other potential difficulties are the positions of drains and chimneys and / or any needed excavations.
e) Single storey rear extension
Where sufficient space is provided a rear house extension has enormous potential to change the very nature of your house. This type of extension can include internal property alterations such as to open up your kitchen to your back garden and create an open-plan area that can be used as a combined kitchen, dining and living area . With this option you will not only benefit from the size increase of your property but you will also add a considerable amount of value to it too. You can use this type of extension to increase the space of your rooms or you could use it to modify or even completely reorganise the way you utilise the interior floor space.
A well designed and constructed side extension will look and feel like a natural part of your home and not like a foreign body.
f) Two storey or multi-storey extension – A multi-storey extension can be built to any part of the existing building.
A double storey side extension can be used to add an additional bedroom or bathroom upstairs or even the creation of a dining room with a spectacular ceiling height.
Due to its more complex nature the costs are higher than the single story extension. Also, the impact on neighbours is much greater and can be done only in detached or semi detached houses with side plot or garden.
As would be expected, the larger the scale of the extension, the higher the value.
This type of house extension will most probably require planning permission.
g) Wrap Around House Extension - Wrap around extensions are created by combining a side return extension and a rear extension together. Mostly they involve building the side wall closer to the neighbouring building border and moving the rear wall of your property into the rear garden, creating an L shaped space.
You could select to have an open plan wrap around extension in order to create a wonderful spacious and illuminated area. A wrap around house could also be great if you want an entire floor remodelling, an increase of your kitchen size, an additional dining room, a living room extension or just to create an additional bedroom or guest-room.
Other additional benefits of this extension type is the high flexibility and the huge increase of value to your home.
However, when you are planning a wrap round extension there are various things you might want to consider such as the overall design balance of your home and the more disruptive nature of this type of extension.
h) An Over-structure Extension - An over-structure extension is an extension over the top of an existing structure such as a garage, a living / dining room or kitchen.
Many UK properties (detached & semi-detached) built within the last 40 years, usually have a single storey side garage. This creates an opportunity for an additional first floor over the garage.
This extension type offers significant benefits compared to other extension types such as the possibility to create a large master bedroom with en-suite and / or extend the kitchen with separate utility, while blending in with the house design and retaining the current garage.
Despite the fact that it is a very attractive extension type there are lots of downsides:
- If your existing structure has only single-skin brickwork it will not be sufficient to build over it as the new brick and block work above will be twin-leaf.
Even if your existing structure has only a single-skin brickwork it could be possible to build over it by dig down through the garage floor and then install a new foundation and a new inner leaf. Alternatively, you would need to install blockwork 'piers' in the garage and fix a steel beam over the top.
- In order to ensure the conditions of the foundations, you will need to dig a trial hole to investigate.
- It could prove to be an expensive method to extend your property.
- A building control permission will almost certainly be required.
