Over the past few years, more homeowners across the UK have been choosing to improve their current property rather than move. And at the top of the list? Porch extensions. They may be small in size, but they can make a big difference to your home’s look, feel, and function.
One reason for their popularity is that they’re often simpler to plan and build than full extensions, making them an accessible option for a quick home improvement win. Whether you’re after extra storage, better security, or just a smart new look from the street, a well-designed porch can deliver.
They also tick the kerb appeal box. First impressions matter, and a stylish porch can completely transform the front of your house. From traditional brickwork to modern glass and timber designs, there’s plenty of room to tailor your porch to match your home and taste.
At MCA Design UK, we’ve seen demand for porch extensions continue to grow. Homeowners are increasingly seeing the value in small changes that have a big visual and practical impact. We design each project with the property and the people in mind – no copy-paste solutions, just made-to-measure design and build services that look good and work well.
What Counts As A Porch Extension?
In simple terms, a porch extension is a small structure built onto the front (or sometimes the side) of a house, providing a covered entrance. It often includes a new door, walls, windows, and sometimes even space for shoes, coats, and parcels. But there are rules around what officially counts as a porch.
In planning terms, a porch must be under 3 square metres in floor area, and the height must not exceed 3 metres. It also can’t be built within 2 metres of a boundary or highway. If your design stays within these limits, it’s likely to be considered permitted development — meaning you won’t need full planning permission.
Porch extensions come in all shapes and styles. Some are open structures with just a roof and posts, while others are fully enclosed and insulated, often with brick or glass walls. From classic brickwork to more contemporary frameless glass styles, there’s plenty of room to get creative.
At MCA Design UK, we guide our clients through every part of this, from checking the legal side to creating designs that blend perfectly with your home. It’s all about getting the right result with no unwanted surprises.
Planning Permission For Porch Extensions
One of the first questions homeowners ask is whether they need planning permission for a porch extension. In most cases, the answer is no – as long as certain conditions are met, it falls under what’s known as permitted development.
In the UK, you can build a porch without planning permission if the ground floor area doesn’t exceed three square metres, the height stays below three metres, and it’s not within two metres of a boundary or public road. But it’s always a good idea to double-check, especially if your home is in a conservation area or already extended.
Building Regulations may still apply, particularly if you’re adding electrics, heating, or structural changes.
We are here to help guide you through the entire process. From checking whether your design qualifies as permitted development to preparing documents if permission is needed, we make sure everything is done the right way with no unwanted delays or surprises.
Design Features That Make A Porch Stand Out
A porch might be a small addition, but the right design choices can turn it into a real statement. The materials, finishes, and features you pick will all influence how your porch looks and how well it blends with the rest of your home.
Brick is a popular choice for classic or traditional properties, offering durability and a seamless look. Timber porches create a softer, more rustic feel, while glass-fronted styles work well on modern homes and add light to the entrance area.
The roof design plays a big role too. Pitched roofs are the most common and suit most homes. Flat roofs offer a more understated, minimalist feel. Gable roofs give a grander look, often used to make a strong architectural feature.
Doors and windows should complement the existing house, and little extras like outside lighting, tiled flooring, and internal storage can make a big difference. A well-thought-out porch doesn’t just look great – it makes daily life easier.
MCA Design UK takes a bespoke approach to every porch extension. We listen to what you want, look at what suits your home, and produce designs that are both stylish and practical. It’s not just about building a porch. It’s about building the right one for you.
How Much Do Porch Extensions Cost?
The cost of a porch extension can vary quite a bit depending on the size, materials, and design choices. For a small, basic porch with a canopy or open front, you might spend around £2,500 to £4,000. A medium-sized enclosed porch with brickwork and windows usually sits between £4,000 and £7,000. Larger, more detailed porches with bespoke finishes and tiled roofs can range from £7,000 upwards.
There are several things that influence the final price. The materials you choose — such as brick, timber, or glass – will affect both cost and overall style. The type of foundation needed, the complexity of the roof, and any extras like lighting, heating, or flooring will also play a part.
We work closely with clients to design a porch extension that fit their budget and vision. We’ll always be clear about costs from the beginning, and we’re happy to suggest value-for-money options that still achieve the right look and feel. The goal is to create something practical, attractive, and long-lasting — without breaking the bank.
Do Porch Extensions Add Value To Your Property?
Estate agents agree that first impressions matter – and a well-designed porch can really boost your home’s kerb appeal. It’s often the first thing people notice when they approach your property, so it sets the tone before anyone even steps inside.
A porch extension can add value, particularly if they improve both the look and function of your entrance. Extra storage, better security, and a warmer welcome all contribute to a more desirable home. For many buyers, having a space to kick off shoes, hang coats, or receive parcels is a big plus.
However, not all porches guarantee a return on investment. If the design clashes with the house or eats into front garden space, it could have the opposite effect. That’s why careful planning and good design are so important.
At MCA Design UK, we take the time to design porches that enhance your home – not just in style, but in how they’re used day to day. That balance of form and function makes all the difference when it comes to long-term value.
Mistakes To Avoid When Planning A Porch Extension
Planning a porch extension might seem straightforward, but a few common missteps can lead to costly setbacks. One of the biggest mistakes is ignoring planning rules. Even if most porches fall under permitted development, it’s essential to check the exact requirements before starting work.
Another pitfall is choosing a style that clashes with your existing home. A porch should look like a natural extension of the house – not an afterthought. Mismatched materials or awkward proportions can affect both kerb appeal and value.
Budgeting is also important. Many people underestimate the full cost, forgetting to include finishes, groundwork, or small extras that add up. Others go the opposite way and overbuild, creating something that dominates the front of the house.
With MCA Design UK, you get clear advice from day one, helping you avoid these mistakes and plan a porch that fits your home, your goals, and your budget.
FAQs About Porch Extensions
Do I need planning permission for a porch extension?
Most porches fall under permitted development, meaning you won’t need planning permission if the size and placement follow UK guidelines. Still, it’s always best to check before work begins, especially if your property is listed or in a conservation area.
How long does it take to build a porch?
The timeframe can vary depending on size and complexity, but most porch extensions take between two and four weeks from start to finish. Planning and design are usually the quickest part when done with a clear brief.
Will a porch add value to my home?
In many cases, yes. Porches improve kerb appeal and functionality, making your property more attractive to buyers. Even if it doesn’t directly increase your home’s market value, it can help it sell faster.
Can I customise the porch to match my home?
Absolutely. At MCA Design UK, every porch is designed to suit the house it’s attached to. We look at materials, rooflines, and architectural style to ensure your new porch feels like a natural part of your property.
What’s the best material to use for a porch?
That depends on your budget and the look you want. Brick is durable and blends well with traditional homes, while timber and glass offer more modern finishes.
