How Much Does a Summer House Cost?

Garden design is hugely popular in the UK due to the vast variety of garden renovation TV programs. As well as this, the rise of more DIY stores and garden centres selling a huge range of innovative products, many people are beginning to see their gardens as extensions of their homes, and many want to put them to good use for both relaxation and entertaining.

Adding a summerhouse adds another dimension to the garden and can be a great place to entertain guests, relax, or even provides a new place for children to play.

Garden outbuildings can vary significantly in their style, size and specification. The price to build a summer house depends on the size of the building, whether a modular or bespoke design, the building materials used, plus the cost of the finishes, fixtures and accessories you choose.

Another cost consideration is whether planning permission is required. The location, size, height, and intended use of your summer house will determine whether planning is required or not.

A small, basic, cheap summer house can cost as little as £500 and the prices can vary right the way up to £10,000+ for a more extravagant larger summer house. Before you purchase a summer house, you need to ensure that you have solid foundations in which it can be built upon.

If you opt to hire a tradesman to build your summer house for you, they can usually build the foundations for you. However, if you are choosing to build your summer house yourself, you need to ensure that you have these foundations down first.

Building a summer house is quite a complex job and you should expect the entire job to take a good few weeks to complete. A typical tradesperson will charge around £150-£200 per day and so you can expect the cost of labour to usually fall above the £2000 mark.

If you are choosing to build a bespoke summer house from scratch, you can expect this to take longer and cost more than a prefabricated summer house.

Labour Costs and Timescales

The cost for labour when building a summer house can vary depending on a wide variety of factors. Below is a list of the main factors that may affect the cost of labour on building a summer house.

Size of Summer House

The size of your summer house can greatly affect the cost of labour. The larger the summer house, the longer it is going to take to build and so, therefore, the more you can expect to pay for labour.

Your Location

Your location in the UK can affect the cost of labour when it comes to building a summer house.

Bespoke or Not

If you choose to have a prefabricated summer house built, this is going to cost a lot less than a custom summer house. A custom summer house will take longer to build and will require further work such as design and calculations to ensure that your dream summer house is going to be safe and secure enough to use.

bespoke

The labour costs for a custom summer house can cost up to £10,000 more than a prefabricated summer house depending on the size and complexity of the job.

Additional Work

Additional work will result in additional costs for labour. If you want any extras added on to your summer house such as extra windows, special materials, or decoration, then you are going to end up paying more for the extra hours that these additional jobs take to complete.

Cost Factors of Building a Summer House

There are a number of things that can affect the cost of your summer house. Below is a list of some of the main factors that can affect the cost of your new summer house.

Type of Summer House

The type of summer house that you choose to have built can affect the cost. As mentioned earlier, a contemporary summer house can range between £500-£5000, a traditional summer house can range between £350-£3000 and a corner summer house can range between £600-£2000.

Size of Summer House

The size of your summer house can greatly affect the cost that you can expect to pay. A small 7’x5’ summer house can cost as little as £350 whereas a larger 12’x12’ summer house can cost up to £5000.

Location

Your location in the UK can affect the cost of having your summer house built. Those located in London can expect to pay as much as £30-£100 more per day for labour than those based in the North of England. This cost can really add up when the work is spread across numerous days or even weeks.

Labour

Contractors can charge varying prices and so the labourer that you choose to complete the work on your summer house can affect the overall cost of the job.

If you choose a contractor that charges a higher daily rate, you will end up paying a lot more as the cost of the job will add up over the days and weeks that it takes to get the job completed. Daily rates tend to range between £150-£250 per day.

Extensive Groundwork

If your garden is not completely level, it may take a lot more groundwork to get the foundations level enough to securely and safely sit your summer house on. The more extensive the groundwork that is needed, the more you can expect to pay as this is going to take longer so will, therefore, cost more in labour.

What's Involved in Building a Summer House?

loghouse

So now you know the prices that may be involved with building a summer house in your garden, but how exactly do you build a summer house? Below is a step-by-step guide on how to build a summer house.

If you are buying a prefabricated summer house, you may find that it comes with a set of instructions similar to these which should help you complete a solid and reliable build.

Step One

The first step you need to complete before starting to build your own summer house is to lay the foundations in which your summer house will sit upon. If you choose a concrete base, this will offer maximum durability.

On the other hand, if you are looking for flexibility, a slab base is much easier to move around. This is handy if you feel like you’ll want to move your summer house to another area of the garden in the future.

You need to ensure that your foundation is flat, level, and even on all sides so that your summer house has an even, flat surface in which to sit on.

Step Two

Create a build plan. You should create a plan on paper of how you want your summer house to look so that you have a basic outline on which to work from. Include in your plan how many doors and windows your summer house is going to have.

The more specific you can be in your planning, the better. you then need to use pre-cuts to build the skeleton of your summer house.

Step Three

When it comes to the roof, you have a few options. If you have a small budget, a tin roof may be the best and cheapest option for you. On the other hand, if you are looking to spend a bit more and get a bit more, a shingled roof will give your summer house a more sophisticated look.

Add your roof onto the skeleton. You’ll now have a good idea of what your finished summer house is going to look like.

Step Four

Once your skeleton and roof are complete, you need to add the flooring and polishes. You should sand down your flooring so that it provides a smooth surface in which to step on. Polish and paint your flooring as desired and wait for it to dry before moving onto the next step.

Step Five

The final step is to add in the walls, windows, and doors. Begin by inputting the walls, remembering to leave room for the windows and doors to be installed.

If you are building the walls from wood, you want to make sure they are sanded down nicely so there are no sharp edges.

This also makes a smoother surface in case you want to paint your walls once it is complete. When inserting the windows, it’s always a good idea to have someone help you by holding them up for you as you fit them.

It can be tricky to install windows without a second set of hands to help.

Can I Build a Summer House Myself?

It is possible to build a summer house yourself, however, it is a very big job and can take several weeks to complete.

Plus, for some parts of the job, you need a second pair of hands to help you. You may save around £500-£3000 on the labour costs if you choose to install your summer house yourself.

If you choose to hire a contractor to complete the work, you can live with the satisfaction that you will be getting a very well-made and secure summer house built.

Although it can be costly, an experienced contractor will be able to complete the job in much less time than you would on your own. Plus, they will have all the tools and materials needed on hand – so you wouldn’t have to worry about a thing.

When it comes to building structures, especially ones in which your family are going to enjoy, you want to make sure that it is a sturdy build. This is why it would be extremely beneficial to have a professional carry out the work for you.

If you live in an area such as this, you will need planning permission to add an outbuilding to the front of your house, and if you want to add an outbuilding more than 20m away from your house, this must not be larger than 10m². You will also need planning permission if you live in a listed building.

Summer House Maintenance

There are a number of things that you may be required to do in order to maintain your summer house.

If your summer house is made from wood, it will need regular treatment to avoid rotting and mould. You should use a high-quality timber treatment or a wood stain at least once per year.

If your wood beings to crack or develop holes, use a filler to avoid any further damage. A typical 5L bottle of wood preserver costs on average between £15-£22.

Regularly check the roof and be sure to treat any rips, tears, or holes. Always be sure to fix damage to the roof immediately to avoid further damage to the rest of the summer house.

If you leave a roof damaged, it could cause leaks and other problems that may be irreversible if not treated immediately.

Be sure to air out your summer house regularly. As there is no built-in ventilation, condensation can develop inside the summer house and this can lead to mould. You should air your summer house out all year round including during the winter months.

Paint your summer house regularly. This helps to keep moisture out of the wood and helps to keep the moisture out of your summer house.
