How much do Builder services cost?

How much do Builders cost? Prices for Builders in 2025 can fluctuate relying on the sort of work that you need to have carried out in your residence.

Are you planning to erect a new house or structure? If yes, then you’d probably want to know just how much it’ll take to get the project over the line to help you set a budget and start to plan. Building a new house is requires huge financial investment and as a result, there’s the need to carry out your due diligence before you proceed. In this post, we’re going to give you an insight into the prices charged by builders to erect a new home or structure.

First and foremost, like every other home project, the price charged by builders to construct a new house or structure depends on a wide range of factors. These factors include the size, location, accessibility as well as qualifications of the builders you wish to employ just to mention a few. For instance, you’d expect the cost of building two-storey in London to be a lot more expensive than the price of a one-story building in Scotland. However, we’ll try our best to give you an idea of the price range you can expect to incur to complete your project.
In general, a builder will charge within the range of £10 to about £15 per hour on the average. For small building projects which includes wall and foundations repairs, a builder will typically charge about £11 per hour. However, the price charge will depend on the extent of the job due to the fact that simple tasks such as repointing only costs about £10 per hour, while laying new foundations can cost up to £15 per hour.

The table shows the types of work that Builders typically do and the average cost range of these tasks. Some tasks take longer to finish than others so prices do fluctuate by job.

Builder FAQs

how big can my house extension be?

The holy grail of home extensions is basically the need for additional space for living as well as leisure. However, before commencing your home extension project, you’d probably want to know just how big your new building can be. In this article, you’ll find the answer to this question which is also frequently asked by many other home or property owners in the UK.

Besides your budget, there are two other major influencing factors that can determine just how much extra room that can be added. These factors include whether you wish to carry out the extension project under Permitted Development rights which is usually for a smaller project or you’d prefer to opt for a larger project which is covered by Planning Permission.

Apart from the limitations in the size of an extension under Permitted Development, the extensions are also a lot more affordable and consumes less time when compared to the extensions under planning permission. So what exactly is the size limit for an extension under Permitted Development and the ones under Planning Permission?

For a single storey extension, the maximum size that can be constructed without having to submit an application for Planning Permission includes:

• An extension should have a maximum length of 6m, if you reside in a terraced home or a semi-detached property.

• Extensions for detached properties can have a maximum length of 8m.

• The extension built must not go beyond half your garden’s area.

• The extension should have a maximum height of 4 metres, but in the event whereby the extension is situated within 2 metres of the boundary of your property, it should not exceed a height of 3 metres.

• The extension should not be higher than the highest part of the existing house’s roof.

how deep do footings need to be for a porch?

No matter how big or small a building is, it can only be as good as it’s foundation - and that’s a fact! It all starts from the footing and when it isn’t deep enough, unlike badly installed gutters or gapped hardwood flooring, can make the whole building collapse to the ground. Just like any code recommendations, the depth of the footings of your porch is a parameter that must be complied with and adjusted to suit your local code requirements.

As a rule of thumb, you should always dig below the frost line when excavating your footings. At this depth level, the moisture present in the soil will be frozen. Ultimately, this will help the ground to act as a barrier to insulate the soil below the footing from freezing during the cold months. As a result, in regions where the weather is almost always very cold the depth of your footings is expected to be at least 48 inches. But in areas featuring a warm climate, you may be allowed to install your footings on grade.

In addition, it’s compulsory that your footings must be installed at a minimum depth of 12 inches below unsettled soil. However, if you’re constructing the structure into a steep hill’s side or by the side of a retaining wall, it’s required that you maintain the least distance to grade both vertically and laterally. In the event whereby you need to achieve a good lateral barrier, you’ll need to have your foundation dug a lot deeper compared to if it’s on a flat surface. For a more accurate and updated information, you can consult your local building inspection department to get familiar with the requirements in your area.

do i need planning permission for a loft room?

Do I Need Planning Permission For A Loft Room?

The answer to this question is maybe. Generally, loft rooms are covered under “Permitted Development which means you won’t need to apply for a planning permission to build a loft room. This is like an advance planning permission provided by local authorities to allow some particular building works to be done such as loft conversions, rear extensions and more. When you’re covered by a “Permitted Development, you’re given the free range to oversee your home’s development without much interference from the regulations or the council. However, for permitted development to apply, there are some specific criteria that must be met. Therefore, if your loft room does not meet the following requirements given below, then you must complete a planning application before proceeding.

• In a terraced house, the converted loft space must not be more than 40 cubic metres.

• In a detached building or semi detached house, the converted loft space must not be more than 50 cubic metres.

• The existing roof slope at the front of the house must cover the extension made.

• The extension should not increase the height of the roof in any way.

• Verandas, balconies and any other structures of this nature must not be included in the extension’s plan.

• The side facing window openings should be at a minimum of 1.7 metres above the ground. The windows must be obscured as well.

• The roof extension should be set back as far as practically possible. It should be at a minimum of 20cm from the current eaves.

• The roof extension should not overhang the house’s roof or it’s wall.

• The materials to be incorporated must be the same or at least similar to what you already have on the house’s exterior.

how much do bespoke fitted wardrobes cost?

Getting the opportunity to fit your very own bespoke wardrobe in your home is a really exciting prospect. However, when planning to install customizable fitted wardrobe, one factor that turns off most home and property owners is the belief that the bespoke solution is actually a very expensive one. But the fact, in reality, is that so far you’re prepared for any associated costs bespoke fitted wardrobes should not make you break the bank to get one done in your home. So if you’re planning to install this type of fitted wardrobe and wondering about the cost, you’ve come to the right place! In this article, we’ve put together the price range estimate as well as the potential extra costs to help you plan ahead and get your dream wardrobe without having to worry too much about unpleasant surprises along the way. Let’s take a look!

With some companies you’ll be provided with a fixed price which can’t be negotiated. While prices from other suppliers will usually start within the range of £1400 to about £1700 for the standard wood finish wardrobe, but this can also reach about £5000 or more for high end or premium finishes, without taking the cost of the added extras into consideration. Ultimately, this often implies having to pay out more money for interiors and additional features than you’re likely going to need. Below is a rough guide to the cost of fitted wardrobes from Spaceslide:

✓ The price for a 2, 3 or 4 door sliding wardrobe starts at £452.37.

✓ The price for a 3 door fitted wardrobe starts at £659.07

✓ The price for a 4 door fitted fitted wardrobe starts at £865.77.

Additional costs you’ll have to consider before getting started includes the cost of hiring installers as well as delivery and removal cost.

how thick should render be on external wall?

Render serves two basic functions. One is it’s protective qualities as render acts as waterproof for the wall which enables them breathe by allowing water vapour move from the inside to the outside of the structure while also working to prevent water or rain from finding its way inside the structure. While the second function is the decorative qualities as render is able to provide the structure with a fine finish and colour to make the building a lot more appealing and correcting faults in line and level in the masonry.

If you wish to apply render on your external wall, you’d probably be wondering just how thick the render should be to perfectly serve both of functions. In this article, we’re going to take a look at just that!

For a render thickness, the British Standard Wind Driven Rain Index has come up with 4 ratings which include Sheltered, Moderate, Severe as well as Very Severe. An area with Very Severe rating include South West England. This rating implies that the thickness of the render in this area should be increased to at least 20mm for a direct one coat render applications as well as 5 to 6 external wall insulation base coat applications. And if you happen to reside within one mile of the coast, it’s strongly recommended you incorporate an extra repellent protection like Paraguard AG from Parex.

In general, render that’s prepared on site with cement and sand should be have a minimum of 20mm to 25mm thickness. Although, it should be noted that the quality of the render is based on quality of the sand incorporated, the design mix as well as being largely dependent on how good the mixing technique from the applicator is. The most common reasons why traditional renders fails is due to both poor mixing ratios and low quality materials used.

do you need planning permission for a loft conversion?

Typically, loft conversions do not require planning permission except in certain situations. They’re usually covered under what’s known as Permitted Development. Certain building works like loft conversion, rear extension and conservatories are granted planning permission by local authorities. Permitted Development, however, gives you a free range to improve your home without having any issues from the councils or regulations. Before your planned loft conversion can be covered under Permitted Development, there are some certain criteria that must be met. This criteria includes the following:

✓ The extension must not go beyond the existing slope of the roof at the front of the house.

✓ The loft space converted must not go beyond 40 cubic metres in a terraced house.

✓ The roof’s height must not be increased by the extension.

✓ The loft space converted must not reach beyond 50 cubic metres in a detached or semi detached house.

✓ The plan for the extension mustn’t involve structures like balconies, verandas or anything other structures of this nature.

✓ The roof extension should be positioned as far back as possible or at least 20cm from the existing eaves.

✓ The side that faces the window openings should be at least 1.7m beyond the floor and the windows should also be obscured.

✓ The roof extension must not overhang the existing roof or wall of the house.

✓ The materials that are to be used must be similar or the same to the materials that has already been used on the house’s exterior.

However, you should bear in mind that there are some properties that are exempt from Permitted Development. Examples of these type of properties include conservation areas, Areas Of Outstanding Natural Beauty and World Heritage sites. Permitted Development does not also provide coverage for listed buildings.

do you need planning permission for a garden room?

So you’ve identified the type of garden room you’d like to construct in your property, chances are, you’ve already worked out where to put it and can’t wait wait to start spending valuable time on it. It’s very understandable to be a little impatient with the whole idea considering the numerous benefits provided by a garden, but just before you proceed with your plans there’s the need to first check whether or not you’re going to need a planning permission.

Factors determining whether you’ll need a planning permission includes where you intend to place it, the size of the room, how it’s going to be used as well as your location.

Generally, most garden rooms do not require a planning permission as they are categorized as outbuildings. In other words, you’re permitted to construct one so far you comply with some specific rules and have permitted development rights at your home or in your area.

If you want to build your garden room under permitted development, you have to comply with the following rules:

✓ The garden room shouldn’t be in front of your home or property.

✓ The total area of your extensions, sheds and outbuildings ( which includes your garden room), must not go beyond 50 percent of the total land area surrounding your property.

✓ It must be a single storey that’s less than 3 metres high ( 4 metres for a dual pitched roof). And it must not go beyond 2.5 metres in height if the structure is within 2 metres of your boundary.

✓ The eaves must not go beyond 2.5 metres above ground level.

✓ It must not feature a balcony, veranda or any raised platform

✓ It must not be a self contained living accommodation.

You should note that if your home is a listed building or you happen to live in a designated area, then you might not have permitted development rights.

Is a basement conversion worth it?

Whether a basement is worth converting depends on your location and how much work it requires.

A basement conversion can be a great way to add space to your home, and can raise your property value. However, it can also be one of the most expensive ways to do this, so if there’s a possibility to extend your property, or convert a loft or garage, it’s worth considering this first.

You should also compare how much your basement conversion will cost with the amount it could raise your property value by. In some areas, a quality basement conversion could earn you money in the long run, but in others it’ll only cost you. If you’re planning on staying in your property for a long time this might not matter to you, but if it’s not your forever home then it’s an important thing to think about.
