  • Porches can be a great way to improve your home’s kerb appeal. Adding a made-to-measure porch is a great way to get rid of clutter in your home and provide space for items you don’t want taking up room in the rest of your house.

    Here at Brittannia our porches are manufactured and designed in our workshop, meaning we can create a porch that is perfect for your house. We offer a range of options for making your porch suit your style and taste. You can choose from a large selection of brick and wall options, select your ideal door and window frames and decide on the size and shape of your porch roof with help from our experts. 

    Our materials are of the highest quality, allowing you to create a unique stylish entrance without compromising on security. We offer a multi-point locking system on all our doors to give you peace of mind about the safety of your home. 

    We want to ensure you have complete design freedom when designing your porch. You can choose from a glass roof for maximum light, a tiled roof to ensure thermal efficiency or a polycarbonate roof to save money; whatever your choice we’re here to make your dream a reality. We will also help you decide how large you want your porch, whether it is simply added storage or a place to sit down and take your shoes off at the end of a long day.

Common Questions

Do Porches need foundations?

No matter how small your porch is going to be, we will always need to add foundations. Without them, your porch will be structurally unsound and won’t last very long. We want your porch to feel like a solid part of your home that will be sturdy for years to come, which is why we insist on foundations. We send a surveyor to your home before we even finalise the blueprints to check where and how deep the foundations need to be.

How big can a porch be without needing planning permission?

Most of the porches we build don’t require planning permission, as they fall under “permitted development.” This means that as long as your porch is no larger than three metres squared and the front of the porch is no closer than two metres away from the edge of your property then you can install a porch with no issues. If you are thinking about adding a porch and the front of your house is close to a road then your porch might not fall under the “permitted development” rule. If you’re not sure, then contact your Local Planning Authority to see what kind of porch is available to you.

Does a porch add value to your home?

Your porch may or may not add significant value to your home, depending on the function it has. For example, if your front door opens straight into a living area and there is no separate area to put shoes and coats, then a porch would add a whole new utility space that is likely to increase the price of your property. If your front door opens onto a hallway where there is already a coat and shoe area, then a porch might not have any real impact on your house value.

What is a good size for a porch?

To ensure your porch is covered under the “permitted development” rule (so you don’t have to apply for planning permission), then you’ll want to make sure that your porch is no larger than three metres squared. Apart from this, the ideal size of a porch will depend on what you want to use it for. If you just want a space to leave your outside boots and coats, then a length of 1.75 would probably be enough. If you want space for a large shoe rack, or a bench to sit down on when removing shoes, then you’ll probably want a wider porch. Contact us and we can give you more information on how to make a porch work best for you.

Features and benefits

Guarantees you can depend on.

We have built up a great reputation over years of delivering a first class service and excellent products, all from our local, no nonsense all-about-you company.

From characteristic country cottages to contemporary town houses, we’re confident that our products will offer a style and finish to truly transform your home. Through constant innovation the quality, durability and security of our products is genuinely second to none. As a local company we are proud to offer British Standards BS7412/PAS24 for enhanced security.

We refuse to compromise on quality

Our windows are made from British Made, high quality MarinespecTM components, with up to 25 years anti corrosion. They are built specifically for the more exposed areas of corrosion, such as coastal environments to give you worry free performance beyond your guarantee.  We believe spending more on components is worth every penny, and sets us apart from our competitors.

State of the art fabrication for best quality

We have invested millions of pounds into one of the most state of the art manufacturing facilities in the UK.  This enables us to provide you with consistently high quality products at exceptionally good prices. Our loyal factory workers are well trained and take pride in their work, they really care about quality.  Our machines are maintained according to a rigorous servicing regime to keep them in top condition.

Superior energy efficiency

Our ‘A’ rated energy efficient and triple glazed windows are tested by the BFRC, which will save you money on your heating bills. By law your windows and doors have to meet strict thermal performance regulations but you can be rest assured that our products exceed current requirements.

Energy saving is incredibly important and so is keeping your fuel bills down. We are continuously looking for ways to make our homes energy efficient and one way is to choose new PVCu windows and doors. Not only will they help to keep your home warmer, they will reduce your energy loss.

Don’t just take our word for it!

Our suppliers conform to strictly controlled and independently monitored Quality Management Systems such as ISO 9001, to ensure that everything is done correctly and according to best practise.

Our windows are tested independently by British Standards for security, weather tightness and strength performance. This means that periodically, we have to send them to independent test houses, in order to be tested to destruction.

These are just some of the many standards the products in our vast range conform to. Needless to say we take the quality of our products very seriously indeed.

The styles available are endless and the choices to suit your home are bigger than ever before. Traditional, contemporary or modern; our versatile window and door designs will create the look you want to complement and enhance your home.
