So you’ve decided that you want an extension for your property, that’s fantastic. But what kind of extension do you want? Unlike conservatories, which come in a set series of styles with a little bit of customization, house extensions can be designed from the ground up to be unique to your property.

Single storey extensions are a great way of expanding your floorspace, often out of the back and into your garden, allowing for ease of access and an amazing view for whatever it is that you want to use your added space for.

Be it a modern home in need of an extra living space, or a traditional or period property that you want to extend whilst keeping the aesthetic of the original property, your extension is sure to be distinct and particular to your home.

Single storey extension design ideas

Your extension’s design is entirely down to your own personal taste and design decisions, not just including its size but also the roof, windows, doors, floors, materials and interior design choices.

Whilst house extensions are brick-based structures, they can be fitted with timber cladding over the outside to bring a rustic look to the property, or have large areas of wall replaced by floor length windows and doors, allowing for unimpeded views and ease of access out into the garden.

Our Bi-folding doors can stretch the length of an entire wall, bringing in massive amounts of light into your property, and able to be folded back in a concertina space for easy ventilation and allowing for the outside to be brought in.

Small house extension ideas

Often an extension is considered when there is limited space to a property, so you may think some of the grander designs seen in brochures are not achievable for a smaller property without acres of land.

But in fact, a bigger extension isn’t always a sign of quality, as even a small extension can make a big difference in terms of space. Large windows that bring in a lot of light can create the illusion of a much larger extension, especially if there are bi-folding door sections that can be folded back to open up your property to the outside.

Smaller house extensions may even be within building regulations to count as a ‘permitted development’, meaning that it does not require planning permission to be built. Even if it is the same size as a conservatory, an extension is much longer lasting and adds a lot more value to a property, as well as providing superior insulation and security against weather and potential intruders.

Home extension ideas examples

The design of your extension depends on whether or not you want an extension that complements or blends in with your pre-existing property, or if you want something that offsets its look with either a highly modern or a traditionally ornate design.

 

Modern, contemporary extensions often have a very minimalistic exterior design; typically rectangular, box like structures, they usually have flat roofs and larger windows often taking up entire walls to create a bright and airy living space. On the outside, the brick structure can then be cladded with either timber or a more modern aesthetic cladding to offset the masonry of the pre-existing property. These sleek, simplistic designs maximise the available space, creating large living areas that can be used as anything from a kitchen diner extension, a study, a sun-room, a play room or even a sitting room.

However, if you are looking for a more ornate, traditional-looking extension that blends in with your properties original style, then there are a number of ways that that could be achieved. This often incorporates original masonry or tiling into the design of the extension, with the walls able to be clad in the same or similar brick that the original property was made out of

Single storey extension roof options

The roof of an extension can make or break it in terms of design and is often a major difference between whether it is seen as a modern extension or a traditional replication of a properties original style.

Flat roofs are a very popular choice for modern extensions, able to be fitted with windows that can take up large areas of the ceiling and allowing for more light. If it is a single storey extension, this can also prevent windows on the upper level from having their view obscured by a raised roof.

Sometimes through, a more traditional roof can be incorporated unobtrusively into a design, with a sloping roof fitted against an exterior wall that makes it appear as though a part of the original properties design. If you want an extension to look as authentic to your original property as possible, although easier said than done, getting the same or similar tiles to your pre-existing roof can go a long way to matching the roof of your original property and making it appear as a natural continuation of the house.

Can you build on a single storey extension?

It could be the case that your property already has an extension, be it one that you had installed previously or one that was already on the property when you bought it; but if that is not giving you the amount of space that you need, then you might be able to have a second storey installed onto it. This doesn’t just create additional space, but also increases the value of your property.

Planning permission would be required in order to get it built, but there is more risk to having it rejected, especially if your proposed extension would obstruct the view or cast shadows on your neighbours houses or gardens. However, if you keep your extension realistic and unobtrusive, then there shouldn’t be much issue.

How long does a single storey extension take to build?

This entirely depends on factors decided during your design phase, with factors including the size of the structure, the materials its being built from, additional features such as windows and doors, and the kind of roof that you want. All of this could make the difference of months in terms of installation length.

However, the typical estimated length of building work when it comes to basic extensions comes out at around 3-4 months, although this itself can be easily raised to 6 if you are getting a larger structure built.

 

What size extension can you build without planning permission?

Planning regulations have been made more flexible in recent years, allowing for larger single-storey extensions to be built without any planning permission. However, it is highly recommended that you familiarize yourself with the planning regulations through the government’s Planning Portal to make sure whether or not your extension qualifies; as failure to obtain planning permission when it is required can result in issues further down the line.

To be exempt from planning permission, an extension cannot cover more than half of the area of land surrounding the original house, cannot be higher than the roof of the original property, and cannot extend past the rear wall more than eight meters (for a detached house) or six meters (for undetached). There are more regulations listed, some of which are dependent on when your property was built and what kind of area you live in, so please click the link above to read them all.
