SINGLE STOREY HOUSE EXTENSIONS IN LEEDS

House extensions in and around Leeds by expert architectural designers

Single Storey Extensions

House extensions are an incredible way to improve your home, and we can help you do it across Leeds, Bradford, Huddersfield and Wakefield. They are an amazing way to enhance your quality of life and to save space as well as increase the value of your property at the same time.

CK Architectural Leeds offer free advice and quotes on all extension and home renovation projects before any commitments are made to make sure you’re happy with the service you’re going to receive.

We work hard to go above and beyond customer expectations and provide an unparalleled service to create the home of your dreams, no matter what your project is.

Types of Single Storey Extensions

There are many types of house extensions to choose from, and they all offer unique benefits. Our single storey extension plans will lead to building eye-catching feature rooms or more space for practical and essential needs. A small single storey house extension can enhance the rooms you already have and work well with internal alterations.

Single storey rear extensions are a great way to add living space to the back of your home if you have the garden to spare.

Kitchen extensions can enhance or create fantastic open and light spaces that can captivate practicality too.

Single storey side extensions can add great space especially if you have an unwanted drive or you are the end of a terrace.

Toilet and utility extension spaces can allow better comfort and get the noisy washing machine out of living areas.

Design considerations

Extension plans need to come from a thorough design process. We need to consider what the site and budget will allow, and then consider gaining planning permission and building control following this.

The most important thing to remember is how you want to live in and use the spaces so that they can complement and enhance existing rooms. Sometimes a small single storey extension can revamp the existing kitchen without taking up too much garden. A larger single storey glass or garden room extension would be the best option if you have the land and a good outlook. It all depends on your unique situation.

The House Extension Process

Building your house extension in Leeds requires a lot of careful thought and consideration. Each and every single aspect of the design needs a multitude of decisions to be made.

Potential issues on site should be established such as shared boundaries, party walls, sewers, or if it is a listed building or in a conservation area prior to all of this, but this is something we will always consider first.

We have the expert knowledge and years of experience to do it smoothly and efficiently above all else helping create the perfect fit.

Design options for extension plans

Once the size and layout of the extension have been determined around the practical requirements, you do not want to end up with dark unusable or impractical spaces, or corridor effect. To prevent this, this is where we explore single storey extension roof options. Tiled mono pitch, dual or ridged, hipped or flat roofs, for example, all have a huge impact on your final renovation.

From here we add the finishing touches with you, discussing and displaying options around glazing, and last but not least, the important wow factors. We keep up to date with trends and new material finishes, plus cheaper alternatives that have similar effects all to make your project work best for you no matter what your preferences are.

Planning Permission

Most Single Storey rear extensions can be built under permitted development. Side extensions can be permitted development also but there are more rules to consider. We give you the necessary advice, and, where necessary, make permitted development enquiries too.

We know exactly what is legally required to be in place before you begin building your house extension in Leeds. Our clear planning application extension plans present your design in the correct scales, site maps, and every other necessary component to validate the application.

We will check the design against the planning guidance such as overdevelopment, impact on street scene, right of light, overshadowing, loss of amenity and outlook, massing/dominance, loss of privacy, and other factors that could affect the project.

Building Regulations

Our detailed building regulations plans will include all the necessary detail such as structure, passage of sound, disabled access, drainage, resistance to moisture, collision, impact, heat loss, ventilation, light, emergency escape and much more. Most alterations to your home will require a building certificate from a building control body, either local authority or private building inspector.

Once the design and planning has been approved you will then need a detailed set of drawings. These drawing can be used for gaining quotation and will be checked against as the building is inspected.

Our specification demonstrates the new extension can and will be built in accordance with the building regulations approved documents. These building regulations drawings will then be submitted for a full plan check, amended if necessary and once approved they will be the standard that is built to and inspected against. Drawings will be used when the building control officer inspects the build to ensure the builder is carrying out the works correctly.

Building a single storey extension

When choosing your builder, choose someone with lots of specific experience and references in building single storey extensions. Choose someone you would feel comfortable working with and talking to about concerns.

Ask where they are based, and be clear about your timescale expectations and specific finishes. Quotations should be clear and easy to read with reference to our detailed approved building regulations drawings. Ask who will be doing the work, will they be sub-contracting and who is responsible. Make sure you know when you need to pay by checking their payment structure and be comfortable with it. Don’t always go with the references they give you, it’s not hard to find out where else they may have been working.

We can offer further help through full project management or individual additional services that can give you better support and clarity when dealing with builders of single storey extensions.

We try to add as much construction details as possible at the building regulations stage, but some assumptions must be made and certain areas investigated before moving forward. Make sure you to remedy them. We offer help throughout for both you and the builder, we will come to site if help is required.
