Single Storey Extension Ideas

Are you looking to expand your property, adding both more space and overall value to your home, then have you considered getting either a one or two storey extension? Extensions can be added to nearly any kind of property, and can be any size, either expanding on a pre-existing room such as a kitchen to create a kitchen diner, or creating a whole new, separate living area that can be used as anything from a sitting room, dining room, sun room, studio or playroom if you have children.

Extensions have proven time and again to increase the market value of your property, no matter its size, in both monetary worth and desirability should you ever choose to sell on in the future. Typically a brick-based structure, extensions differ from other home expansion installations such as conservatories as they do not come pre-fabricated and thus can be constructed to fit your precise, unique design from the ground up. With their brick walls being able to be fitted with pipes, plumbing, electrical wiring and more, allowing for running water, lights and heating, the possibilities of how you can use your extension are endless, from kitchen expansions and bathrooms to workshops and studios.

Single storey extension design ideas

When it comes to the outward design of an extension, it can either be made to complement and blend into your pre-existing property, or contrast it to highlight features and off-set a traditional design with a more modern, minimalistic design.
A more traditional, complementary design can be achieved through sourcing bricks and stone either the same is similar to one ones used on the original property, which can be used as an outer cladding, and tiles mimicking the ones from your roof. This design will seamlessly blend your extension into your home, making it seem as though it is a natural continuation of the property.
However, if you are looking for a more minimalistic design, these can be left off and instead have a more modern timber or plain coloured cladding, with a flat roof to create a simplistic yet trendy box-shape.

No matter the outward design, you can have you extension fitted with large windows or bi-folding doors that can stretch along entire walls in order to open it up and provide ease of access to your garden, bringing the outside in and providing ventilation and unimpeded views. Traditional or modern, all extensions can benefit from the best of modern technology that also gives you a classy aesthetic.

Small House Extension Ideas

You may be thinking that extensions are a commodity only really usable on larger properties, or homes with larger outdoor spaces, but that couldn’t be further from the truth. In fact, extensions are most commonly considered precisely because your property needs that extra space to make it comfortable or to fit your envisioned house design.

A bigger extension does not always equal quality, and there are many cases when even a small, box-shaped extension has added new life to a property, expanding the kitchen or dining room and incorporating bi-folding doors to open it out into the garden to create even more usable space.
Additionally, having a smaller extension can not only save you money in terms of construction, but it can also mean that you may be exempt from requiring planning permission. Planning regulations have recently changed, allowing for certain extension options under a certain set of dimensions to be built without any kind of planning permission process, saving you money and bringing forward building work by months.

Single storey extension roof options

A flat roof is more modern, allowing for unobstructed views for the upper floors and also allowing for additional double glazing units to be installed to maximize the amount of light entering your home. Skylights can be added to sloping roofs too, but flat roofs can allow for larger sections to be installed, or even having the whole roof be made of them.

Sloping or triangular roofs are the more traditional, with tiles that either replicate or contrast with the roof materials of the pre-existing property.

Additionally, lantern roofs that mimic the traditional triangular roof shape whilst being made entirely out of double glazing, can bring a touch of sleek class to an extension, promoting rain runoff and adding that additional height and illusion of extra space.

Home Extension Idea Examples

Looking online can provide a great variety of different designs, both in the shape and style of the base extension and the additional features that you can have added, such as particular windows, doors and roofing options.

The interior design of your extension matters just as much as the exterior, as while the outside of an extension is made to suit the outward appearance of your property, inside is where you can really go wild in terms of your personal taste.

No matter what you want to use your extension for, however, because of their highly adaptable nature, you can change it around at any time; this means that potential future homeowners, if you ever choose to sell on, can then use it in any other capacity the please.

Can You Build on a Single Storey Extension?

But what if you house already has an extension? Maybe you aren’t looking for more space on the ground floor, but would really benefit from some extra room upstairs. Adding a second storey extension is easier than you may think, being around the same price as a ground-floor, single storey extension and only requiring a few additional joists and fixtures in order to make it structurally sound to walk on.

Planning permission is a necessary requirement for second-storey extensions, with a bit more risk that it will get rejected, but don’t let that put you off. As long as you keep your extension unobtrusive and realistic, not obstructing the view or sunlight for your neighbours, then you should be golden.

How Long Does a Single Storey Extension Take To Build?

The length of an extension installation is going to be considerably longer than pre-fabricated conservatories, because of their brick-built structure needing more labour in order to be built. It also depends on factors incorporated into your design, such as the size of the structure, what materials it is being made from, whether you are having bespokely made features added, and what kind of roof you want.

However, your typical house extension installation has been estimated at an average of around 3-4 months, with larger structures taking around 6 months. However, these times can be affected by your design, so it can vary on a case-by-case basis.
For a more personalized estimate, it is best recommended that you consult with your installation team.

What Size Extension Can You Build Without Planning Permission?

Planning permission can be a real pain in the neck at times, adding months onto waiting time for building work to start and costing you more in fees. However, regulations have been made much more flexible in recent years, meaning that more and more extension installations can be given the go-ahead without any planning permission whatsoever.

This can, again, vary on a case-by-case basis, and it is highly recommended that you familiarize yourself with the regulations through the government’s Planning Portal, as failure to obtain planning permission can result in issues further on down the line.
These regulations lay out that, to be exempt from planning permission, an extension cannot cover more than half of the original land surrounding the house, cannot be higher than the properties pre-existing roof and cannot extend past the rear wall of a detached house more than eight meters (or six for an undetached house). There are more regulations listed, and some of them depend on when your original property was built, so please follow the link above to read them all.
