    Cost Factors of Building a New Porch

    There are a number of factors that can affect the cost of building a porch. Below is a list of cost factors that you should be aware of before you decide to build your new porch.

    Size of the porch

    As you can expect, the larger the porch, the more it is going to cost you. For the entire cost of a porch, you will be looking at paying approximately £1,400 per square metre. So with this in mind, you can see how the price can drastically rise if you choose to build a larger porch.

    Number of windows

    A new window for your porch will cost between £300-£1,000. Therefore, the more windows you want to have in your porch, the more it is going to cost you.

    Style of roof

    The two most popular styles of roof for a porch are a tiled roof and a rubber flat roof. Roof tiles tend to work out more expensive than a flat roof. You should expect to pay around £0.80-£1.80 per roof tile and around £80 per metre squared of flat rubber roofing.

    Type of porch

    Types of porch can vary in price also. For example, if you would like a lean-to, you can expect a uPVC porch cost to be around £2,500, whereas a flat gable roof porch costs roughly £3,500.

    What's Involved in Building a New Porch?

    Building a porch can be a difficult job, and it’s important that the job is done safely, precisely, and accurately. Therefore, it is recommended that you hire a professional to build your porch for you. However, the eight steps below explain how to build a basic enclosed brick porch that features windows and a door.

    porch building

    Step One

    The first step in building a porch is to lay the foundations. When you are building the foundations, you need to be sure that they have been dug deep enough to provide ample stability. You should be aware that the depth of the foundations can vary depending on pipes and cables that may run underneath or based on the soil type.

    Step Two

    The second step is to lay down the damp proof course. This prevents plants from growing underneath and breaking through the foundations, and it also prevents any dampness from leaking through into the porch area and potentially spreading through to the main home.

    Step Three

    After you have laid down the damp proof course, you must lay concrete over the top. This concrete acts as a subfloor. If you have decided that you are going to lay a timber floor, this is the best point to lay joists to support your timber flooring. If you are laying other flooring types, you want to be sure that you lay the concrete subfloor high enough for your other flooring to be laid on top.

    Step Four

    The fourth step in building the porch is to begin laying the bricks and lay the floor. Begin by building the porch up to the level of the damp proof membrane of the main property. Be sure to lay bricks accurately and evenly up to this point so that the flooring can then be laid easily.

    Step Five

    It is now time to lay your flooring on top of the damp proof course. Be sure to lay your flooring evenly and carefully. Once the flooring has been laid, add a cover over it to prevent any impact or water damage from affecting it while you are still in the building process.

    Step Six

    If you are planning on installing windows to your porch, you will now need to lay bricks up to the window level. Once your bricks have been built up to the window point, you can install a windowsill if needed. Once your windowsill is in place, you can then continue building up the brickwork to the height of the roof timbers. When you reach the top of where the widow will sit, you should fit an intel to this area.

    Step Seven

    When all of the brickwork has been completed, you can then work on building the roof. The first step in building the roof is the create a timber framework that you can work off. Then you must install a breathable roof membrane to protect the ceiling and the rest of the porch. Once this is completed, you can then lay the roof tiles or lay the roofing sheets, depending on the type of roof that you have chosen to build.

    Step Eight

    Once your roof is complete, you should add guttering. It is important to add gutters to the porch to prevent any water damage that may evolve over time. Guttering improves the drainage and will reduce the potential for flooding.

    Finishing Touches

    Once all of the above steps are complete, you can then install the windows and doors to your porch, and you can plaster and decorate it how you wish.

    Types of Porch

    There are many different types of porch, and each one comes with their own set of advantages and disadvantages. Below are the different types of porches that you can add to your existing home and the pros and cons of each one.

    Things to Consider Before Building a Porch

    When you are ready to build your new porch, you need to choose a good tradesperson or company to carry out the job. A good trade company will discuss design, implement your ideas, listen to your desires and work out a design that you will love for a reasonable price.

    In addition to choosing the right company, you need to think about the materials, design, and overall finish of your porch. This helps to ensure you can afford your perfect porch and will also help you to determine how long the job is going to take.

    If you wish to build a porch with a custom paint job, and a unique design then you need to make sure you budget accordingly. Most contractors will charge additional fees for custom designs, and unique work so keep this in mind when deciding on the ornate detail work you would like to see on the new porch.

    Lastly, make sure you have a full written quote and guarantees. This is not just so you know exactly what you are paying for the design and finish, but also so that you know how long the porch will take to complete, and all of the guarantees that the company offers to you.

    Will I Need Planning Permission to Build a New Porch?

    To add a small porch to the front of your property, you won’t usually need planning permission. You will only need to apply for planning permission if your porch meets any of the following criteria:

    • The external ground floor area exceeds three square metres.
    • Any area of the porch is more than three metres above ground level.
    • If any area of the porch is within two metres of any boundary.
    • If any area of the porch is within two metres of any public roads.
    • If any area of the porch is within two metres of any public footpaths.

    If you do find that you need planning permission for your porch, this will cost you £172 in England.

    What Type of Roof Can I Have on My Porch?

    There are several different roof designs for porches in the UK. Below is a list of the most popular types of porch roof and some information on each of the different types.

    Pitched Porch Roof Cost

    A pitched roof is a great design that works well on the majority of homes. It is perfect for those who have wider homes or for homes that have a small front garden with not as much room.

    Price per m² – £30-£65

    Gable End Pitched Porch Roof Cost

    A gable end pitched roof is the perfect choice for homes that have a good amount of room at the front. Similar to pitched roofs, a lot of homeowners like to use the peak at the front area of the porch as a nice decorative feature.

    Price per m² - £30-£65

    Flat Porch Roof Cost

    A flat roof offers a very subtle and contemporary look to your porch. Flat roofs are best for homes that feature a large window above the space where the porch is being built.

    They are also great for bungalows that have a low roofline.

    Price per m² - £35-£70

    Double Hipped to Wall Porch Roof Cost

    A double hipped to wall roof is very similar to a pitched roof; however, they offer a more traditional look to the property. This type of roof is perfect for older properties as they are Elizabethan in design.

    Price per m² - £50-£100

    Double Hipped to Ridge Porch Roof Cost

    Price per m² - £25-£60

    Single Hipped Porch Roof Cost

    Single hipped roofs are a very neat design and are smaller than most other roof designs. This type of roof is perfect for properties where the floor space comes at a premium. They’re also great for homes where the front elevation appearance can’t be altered.

    Price per m² - £30-£65

    Why Should I Build a Porch?

    There are many reasons why you may want to build a porch onto your home. Some of the main reasons you may want to add a porch to your existing property are listed below.

    • More space – Homeowners often crave more space in their homes and a porch is a great way to introduce some extra space in your property.
    • A better entrance to the home – A porch offers a grander entrance to the home.
    • Keep the heat inside the property – A porch is a separate room which means that you don’t have to open the front door and let all the heat out. Instead, the heat can remain in the home, and the cold air from outside will only enter the porch area.
    • More security – A porch offers an extra layer of security to the house. You can have a lock on the external door as well as the door that enters the home.
    • Storage opportunities – You can store many things in a porch such as your shoes and coats which will free up space in the home.
    • Increase the value of the house – A porch adds value to your home, which is great for if you decide to sell your home down the line.
    • Aesthetically pleasing - A porch is a beautiful addition to the outside of your home and is very pleasing to the eye.

    What are the Benefits of a New Porch?

    There are many benefits to adding a porch onto your existing property, aside from them being aesthetically pleasing.

    The first benefit is the extra space that a porch offers. Homeowners tend to be always keen to look for ways to create extra space in their homes. A porch is useful for hanging garments or for storing shoes.

    A porch also acts as a great extra layer of defence against any potential intruders.

    Porches can also help to improve the energy efficiency of your home by preventing a lot of heat loss to the outside. A well-designed porch will allow you to enter the porch, close the external door, and then open the door to the house, so the warm air inside is retained.

    Can a New Porch Increase Property Value?

    A porch is a great investment because it can increase the value of your home. Porches are a desirable feature among people who are searching to buy a new home.

    When you come to sell your property, you will usually gain more money back than the finances it takes to build the porch.

    pvc porch

    Due to the added security and the benefit of looking appealing on the outside of the home, people will be willing to pay more for a home that has a porch attached to it over a home that doesn’t have a porch.

    In some cases a high end porch can increase the value of your property by up to 10%. This not only means that you will get the money back that you spent on the porch, but you will also make some extra money back from adding a porch onto your home.

    Can I Build a New Porch Myself?

    Building a porch is a complex job and will take a minimum of 2-3 weeks to complete. The job requires a lot of specific knowledge in terms of materials, design, and execution. With this in mind, building a porch is a job that is best left to licensed professionals. Due to the complexity of the job, it is always recommended that you hire a company or tradesperson with the skills required to build a porch.

    It is also important to make sure that your porch fits in with building regulations. This is so that, if you ever come to sell your property, you will have all of the correct paperwork. A professional porch builder will know everything necessary to carry out the correct work needed to fit in with building regulations.

    If you decide to build your porch yourself, you will save money in the short term as you won’t have to fork out for the cost of labour. This can save you a few hundred pounds as labourers tend to charge around £14-£30 per hour. However, if you are not fully competent and don’t have the advanced knowledge needed to build a good and reliable porch, you may end up having to spend even more down the line.

    Cost of Removing a Porch

    There are many reasons why you may want to remove a porch. Perhaps it is up against an older home with issues that require remodelling, or maybe you want to make room for a new installation, or you may find that you just don’t want a porch anymore. Below is a list of the steps that you will need to take in order to remove a porch.

    remove a porch

    Preparation

    Before you begin the dismantling process, you will need to make a plan for removing the rubbish. It is a good idea to hire a skip from a local company. A one-week skip hire will cost you around £200 to £250.

    You should start by cutting the power to your porch area so that you can safely remove all of the necessary wirings during the demolition.

    Removing the Roof

    It is safest to begin by removing the roof from your porch. Start with the guttering and any trim work. You may find that you need to get a hammer to some of the tougher areas, or if any parts are screwed on, be sure to unscrew them before you start trying to remove them.

    Once this is complete, scrape away any underlays or waterproofing to expose the roof panelling. Some tougher panelling may need to be pried loose, and others will simply unscrew. If you are not planning on reusing the materials, it can make the job easier if you saw the roofing panels into smaller, manageable pieces.

    Removing Walls

    Start by removing any windows and doors from the walls. From there, you can begin to knock down the walls, being very careful to avoid any falling debris. It is always best to work on a small area at a time and make your way along the wall until all of the bricks and panelling have been loosened and removed. For the sake of safety, start from the top of the wall and work your way down to avoid any large debris from falling onto your head.

    Removing the Flooring

    For wood flooring or vinyl flooring, it is easiest to remove this by cutting into it. Set the depth of a circular saw to around ¾ of an inch and then cut the flooring material plus the subfloor into manageable 3-foot sections.

    Be sure to sink the saw into everything at once and then pry them away from the floor joists. Tiled and stone flooring is a little bit more difficult as this will require the use of a jackhammer to expose the subfloor. Finish up by cutting the floor joists down and prying them loose.

    If you are thinking of hiring someone to remove a porch for you, you will be looking at paying somewhere between £14-£20ph for the labour.

    Hiring a Porch Builder Checklist

    • Hire a company that will work with you on all areas of the design of your new porch until you are completely happy with the proposed design.
    • Make sure the company will include detail work and that they can supply the materials that you want for your new porch.
    • Consider if they are able to provide custom design work if required.
    • Make sure they work on the foundations before construction commences so that you can be sure your porch is on level and even ground.

    FAQs

    How much does a brick porch cost?
    Depending on the features that you are looking to have on your porch, you should expect to pay between £3,000-£5,000 for a typical brick porch.
    Can I install a porch on my existing base?
    As long as the existing base is in good working order, you can definitely install new wall frames onto it that can be built into a working porch.
    How long does it take to build a porch?
    For a simple 3 metre porch, you should expect the work to take around 1-2 weeks. This is the length of the complete process from the design stage to the complete construction providing there are no setbacks along the way.
    Can I order custom materials?
    Yes, it is possible to order custom materials; however, it is worth keeping in mind that this will take longer as the contractors will have to wait for the supplies. It is also going to cost more, depending on what you request. Be sure to discuss these details with the contractor during the design stage.
    Can I hire anyone to carry out the work?
    It is always best for you to hire a company that specialises in new porch construction. This way, you can guarantee that you have a trustworthy and professional team in place to carry out the work correctly and efficiently. This also ensures that the correct methods of work are carried out through all stages of the job.
