Types of Single Storey Extensions
There are many types of house extensions to choose from for your property in Liverpool, 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 double storey extension offers all of this too, plus more value for money with still just one roof and foundation, plus a room upstairs too.
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.
Side extensions can add great space especially if you have an unwanted drive or you are at 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 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 house extension plans
Once the technicalities are worked through and considered within your designs, it’s time to explore what kind of creative options are present.
The biggest things to think about in this part of the process are roofing, materials, glazing, facilities, access, impact on existing rooms, and what it may look like when decorated, too. Each is vital to the overall success of the design since it is going to be a permanent addition to your home (and increase its value).
We’ll always be on hand to help you make any decision you aren’t sure of using our years of expertise in the industry, as well as do everything that we can to incorporate the things you love or know you want to be involved in the finished product.
Planning Permission
House extensions in Liverpool often require planning permission to be built, and we’re highly experienced in working with local councils to create designs that account for this. We’ll take into consideration things like privacy, impact on the street scene, the area you have to work with, and anything else that your local council consider.
For smaller extensions, there is also the potential for Permitted Development Rights to be utilised too. This is where planning is not required as you are allowed to make smaller changes without it, however, it may still be recommended that you get a certificate of lawful development to provide this should you ever sell.
Whatever your situation, we’re always happy to provide advice both before and during your project to make sure you have the best chance of success without any wasted time.
Process of application
We know exactly what is legally required to be in place before you begin building your house extension in Liverpool. 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 the 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
House extensions in Liverpool also need building regulations drawings to be provided to building control in order to be considered safe and legal to build. We have a huge range of experience with both private building inspectors and local building control authorities and will be more than able to help you obtain your certificate.
Whether we take you through the entire process or simply provide the building regulations drawings for your project, we’re happy to help you with any project.

- Building control approval
- Full approved plans
- Building regulation drawings
- A site inspection of your project
We can help you gain each of these individually and again liaise throughout where required to make sure there is no room for error or confusion and to give your project the biggest possible chance of success.
Our drawings can then be handed to a builder to quote upon before they inspect the site themselves for anything undocumented and begin the construction process.
