How much is the total cost of building a Single Storey extension?
Extending your home can be a hefty job, especially when there are so many aspects to consider and decisions that will affect the entire process before proceeding with the new extension.
There are a whole host of rules and regulations that we encourage you to follow so that you can go ahead and dive in. The house extension cost varies depending on various important factors, for example, the use and the extension size you desire. Much smaller and less complex site extensions are typically the most affordable.

Ideas for Single Storey House Extensions
You can utilise a new single-storey extension for your original household in many ways, and our Trimble architects are blessed with immense creativity and innovation. They can provide all the best ideas to enhance your home project in a suitable, practical, stylish, and visually pleasing way.
Two of the most popular ways to go about a single-storey extension is to turn them into either kitchen or wraparound extensions.
The heart of the home is typically considered to be the kitchen, as many adults will spend at least an hour or more in this part of the property preparing food or chatting, as the kitchen is quite favoured among the other rooms of the property for most Brits.
Its importance is often why kitchen extensions are one of the most popular uses of the single-storey rear extension for homeowners across the UK.
For those who wish to invest in a single-storey extension to expand your kitchen space, it will allow you to curate a brand-new, updated and vibrant design, enhancing the potential of your household overall.
A single-storey house extension is a building type under the permitted development rights, making it incredibly easy to create an accessible open space that works best for you and your household, practically and visually.
However, before gathering builders and surveyors, you'll want to ensure you obtain a party wall agreement. Party wall agreements are vital for building any project affecting the adjoining properties, meaning any neighbouring buildings and individuals.
In recent years, the rules of planning an extension have been relaxed; however, even those households and terraced houses with Permitted Development rights will still need proof of a party wall agreement. Warning those in your community about the new developments is essential so that they are aware of any off-road parking and disruptions.

We'll work with you to ensure your new build layout plans and drawings match the criteria to gain the necessary planning permission and your budget whilst adding luxurious touches to enhance your vision.

Wrap Around Extensions
We would encourage you to take your single-storey rear extension perhaps a step further and begin designing a wraparound extension for your household or property.
Such extension will allow you to create more flexible living spaces to suit any occasion and incredible openness. Generally, the wraparound extension wraps itself around the existing structure to form an 'L-Shape.'
However, please be aware that you, the householder, must complete planning applications and receive approval from your local council or authority before proceeding with construction.
Contact us at Trimble today if you require assistance filling out your planning application or need any plans assessed to see whether they would be approved based on your area's criteria and building regulations. Our trusted professionals can visit and look at your plans, giving in-depth advice and any help you need.

Frequently Asked Questions about Single Storey Extensions
Deciphering the general build cost of your single-storey rear extension is one of the most challenging aspects of any new build or extension project. You'll find the other aspects, like planning and designing, can be pretty fun and exciting. The overall price will typically depend on many factors within your briefs, such as labour, square metres and material costs.
However, various general costs of building a single-storey extension at the rear can be summarised within the following price ranges:
UK Average Square Metres: £1,200
London Average Square Metres: £1,400
These are examples of the general costs for a standard extension within the UK and London; the capital cities of any country or continent will always be costly no matter the service you're after, which explains the excessive London costs. Higher-end extensions in London and the surrounding areas can go up to around £2,300 square metres.
Much like any other build, its use will dramatically impact the costs involved, so it's best to have a general idea of the class or use of build your extension fits into.
During the planning stage, you want to curate an idea of how much you wish to spend on a brand-new kitchen, bathroom, living room or bedroom extension for your single-storey. Typically, the kitchens and bathrooms are the most challenging to budget as you must consider and implement the final costs of drainage plumbing, all the appliances and fitted joinery.
The cost of installing kitchen compartments, plumbing and appliances like gas meters into your extension will be around £10,000 for the cheapest designs.
The final price will typically depend on the overall quality of the appliances and materials you wish to have installed, such as bespoke flooring like engineered wood floors, light fittings, brand-new appliances, or simply painted walls. Often, the most cost-effective ways of extension are a tad more costly than the generally cheaper options but offer an incredibly long lifespan.
To add a bathroom to your extension project will mean the cost is significantly increased by approximately £5,000, yet the price could get higher depending on the finishes you desire.
The general rule of thumb for budgeting any extension, whether one or two-storey extensions:
Architects throughout London typically take up 10% of your budget. The administration and other professional fees will often take up 1%, and your structural engineer will take approximately 4%.
Your quantity surveyors will, on average, take around 3%, and your contractors will take up 30% of the budget. The materials used will amount to 20% of the final budget, with the fittings and glazing of windows and doors taking up 5% and 15%, leaving a final 20% for the VAT.
You must assess your desired building works against the final budget finish, as this will often help decipher which extension style and bespoke options are best for your household and the costs you can afford.
You can extend along the side and separately at the rear without receiving any planning permission, as this is considered under permitted development.
It's paramount that any single-storey rear extension cannot simply extend beyond the rear wall of your current home by any further than 3 metres for a semi-detached house or, if your current home is a detached house, no further than 4 metres.
Similarly, the maximum height of your single-storey rear extension must not proceed further than 4 metres; otherwise, you'll find that you will require planning permission.
Any side return extensions tend to fall under permitted development, as long as they do not extend more than half the width of the existing house. As long as it is a single-storey extension, you can extend to a maximum of around 3 metres but cannot pass the front elevation.
Nationwide has conducted a lot of research showing us how home extensions and other home improvements can drastically add value to your property that you may not have even considered.
Single-storey household extensions can add approximately 23% value to your initial existing property.
