Building an Extension Checklist
Building an extension can often feel like ticking off a never-ending checklist.
However, while the process can be drawn out, you can ensure that you get all the essential bits right by following a few straightforward steps.
If you carry out these tasks, you’ll be sure to get a stunning extension that gives you the home of your dreams.
When you build an extension, there’s plenty of base work that needs doing, as well as the overall installation. However, you won’t have to put your life on hold.
You can work with a trusted local installer who’ll help you to create your extension, and they’ll work around your life to give you the minimum amount of disruption.
Because of this, you can stay in control and get all the elements of your installation right. With this checklist, you can get around planning permission regulations, avoiding plenty of red tape.
Not only that, but you can find out how to design and customise your extension to give you a bespoke space that provides the best possible performance.
1. Choose the Dimensions of Your Extension
The first, and perhaps most crucial, part of building your extension is deciding how large it will be. A smaller extension will cost less, but won’t give you as much space or use as many energy-saving materials. Additionally, you may have limits on the shape, like the design of your house and the size of your property.
When you choose the dimensions, you should also consider how your new space will blend into your home. For example, you may want more than one storey in your new room, but it could extend past the roofline, meaning it’ll need planning permission.
Not only that, but if you want to have a unique shape, then you can expect to pay more and have a more complex installation too.
Another significant factor to consider is where you want to install your new extension. The location is crucial not only for planning permission but for how the build enhances the rest of your home. With materials like double glazing, brickwork and other options in the right place, you can allow more natural light and warmth into your living space, making it more comfortable.
2. Carry Out a Technical Survey Where You Want to Install Your Extension
Once you’ve nailed down the precise size of your new build, you need to make sure that the ground underneath can support it. If you decide to build an extension on your own, you could find that it begins to sink and become unstable on uneven ground. Because of this, it’s essential to carry out a full technical survey of your property.
To do this, you can hire out a specialist who’ll survey your ground and check it for any issues. If some do arise, then you can work with them to change your plans and find another area of your property that suits an extension more. That way, you’ll be compliant with building regulations, and you’ll ensure your extension can perform for a lifetime.
Your surveyor will also check underneath your garden for anything that may cause an issue, like sewage and drainage pipes. Additionally, they can help you to carry out any base work for your extension, creating an even space in the soil for your new addition. As a result, you’ll make sure your extension doesn’t damage your garden or cause any unforeseen problems.
3. Make Sure Your Extension Meets Planning Permission Guidelines
Planning permission is one of the most stressful parts of the building of an extension checklist. However, you can get around it with ease when you seek professional advice from a trusted local installer. You can get in touch with one through the Conservatory Prices UK network with approval from bodies like CERTASS and FENSA who’ll ensure your new build meets the rules.
Some of the rules to consider include:
- The extension can’t cover more than half the land around the original house (meaning the house as it stood on the 1st July 1948)
- The extension can’t be higher than the highest part of your roof
- Extensions of more than one storey cannot extend further than three metres from the rear wall
- Single-storey extensions cannot extend further than eight metres from the back wall in a detached house and six metres for any other house
There are also plenty more guidelines; however, you can check them both with your expert installer and with the Government’s helpful planning guides. As long as you follow these steps, you’ll be able to install your extension quickly and to reap the rewards of your installation. Planning permission can also help you to design the shape of your space.
4. Select the Best Materials for Your Extension
After you’ve ensured your new addition can fit your home seamlessly, you can decide which materials to use in the build. You can customise your extension in endless ways, with windows, doors and other accessories. With each, you’ll get a selection of advanced materials that save energy, improve security and make your space warmer and brighter.
For example, you could want to design a stunning, open space with panoramic views of your garden. Glass house extensions give you double glazing across the walls of the room, meaning you’ll get gorgeous light without compromising on warmth. That’s because the glass is air-tight, stopping heat from escaping and cold air from entering the room.
Alternatively, you can install more robust structures, such as brick walls or solid roofing. These materials are much more durable and secure, giving you a feeling of privacy and seclusion with their terrific sound insulation. However, they still work to insulate your home, and you can add windows and doors with double glazing to take complete control of lighting your space.
5. Choose Windows and Doors for Your Extension
Windows and doors are a massive part of building an extension and should be high on your checklist. You won’t only get beautiful materials with these designs, but elegant looks as well. With many of the local suppliers in our network, you’ll be able to choose from the most popular styles of windows and doors to style your new extension precisely to your vision.
You could fit sliding sash windows, for example, which have an elegant upward opening. You can choose either uPVC, aluminium or composite frames too, that are durable and won’t twist in wind or rain from outside. Alternatively, you could even select ceiling-to-floor windows or a roof lantern to get warm light into your space through a dramatic design.
Doors are also a significant way of improving your extension. You can fit doors to the front and back, connecting your extension to your garden and blending your new space in seamlessly with your home. For example, there’s the option of sliding and
6. Connect Your Extension to Your Home
Your new extension should blend seamlessly into your home and feel like it was always there. That’s why you can design your space to do just that. You can select brickwork that matches your existing property, and your installer can connect your new area to your mains electricity and plumbing. That way, your extension will feel like a regular part of your existing home.
Doors can also help you connect your extension to your home, or to make it feel separate too. For example, composite doors provide a sturdy, robust design that makes your extension feel more private. With the option of tiled roofing, blinds and many other features, you could create an entirely secluded space for your family, or only you, to enjoy.
Finally, you can begin to work out precisely how you want to use your new extension. You could create a new kitchen, dining area, or even a bedroom. The choice is all yours, with flexible materials and customisable options at your fingertips. That way, you’ll create a warm and bright space that can transform your whole home.
7. Compare Building Extension Prices
To complete the process of building an extension, and to tick off your checklist, the last thing to consider is the cost. B
