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.

how much does a single storey house extension cost?

If you’re planning to build a single story house extension, this is one of the first questions that usually comes to mind to help you set a budget and start to make plans. But as simple as it seems, a single accurate answer can not be provided due to the fact that there are several variables that can play a key role in influencing the price of a single story house extension.

In this guide, we’ll provide you with a rough estimate that you can work with to put you on the right path.

For a small extension, you can expect to spend a sum within the range of £14,000 to £17,000. Meanwhile for a larger single storey extension, if you opt for a large wrap around the extension with a great amount of glass to be incorporated in both the walls and roof, you can expect to pay a sum within the range of £80,000 to £120,000.

Overall, the average cost of a single story house extension is usually within the range of £34,000 to £37,000.

Storage space is a major consideration for most home buyers and even more so, when there’s the presence of fitted wardrobes.

can i build a room in my garden?

The short and simple answer to this question is yes, you can build a room in your garden. In fact, if you want an additional space for a living room, dining room, games room, study room or perhaps you want something as cool as a pool house, then looking at your garden for a solution may just be the perfect answer to your need for an extra outdoor living space.

Outbuildings such as garden rooms do not usually require planning permission as they’re usually covered by the permitted development. As a result, making it even a lot more attractive to homeowners who would not like to pass through the stress involved or pay the money required to submit an application for planning permission. However, if you need your garden room to be covered by permitted development ( if it’s not a listed building or in a designated area), you must follow these guidelines:

✓ 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.

The position of your garden room will be partly determined by the space available in your garden. If you need it to link it to your utilities then positioning it a bit close to your main house would be a cost effective choice unless you’re using off grid sources of power, heat as well as water.

What is plasterboard?

What Is Plasterboard?

The plasterboard is unarguably one of the most common building materials across the globe. Sometimes referred to as gypsum board, gyprock, drywall or wall board, the plasterboard is mostly incorporated for ceiling cladding and interior walls in several homes and offices in recent times. However, despite its global acceptability, it’s a very misunderstood building material.

The plasterboard is manufactured using a gypsum core with a heavy paper covering both sides of the sheet. The measurement of a standard plasterboard sheet is a length of 2.4 metres in and a width of 1.2 metres, with a thickness of about 13mm. The board usually have either a bevelled or a bit flat edge. The bevelled edge makes it easy for the installers to use a plaster to smooth out the surface after nailing the sheets to walls and ceilings as well as taping the edges.

The plasterboard comes in different types. Although various manufacturers provide a unique name for their products, but they’re all included in one of the following categories:

• Water Resistant Plasterboard - This type of plasterboard are best suited to be used in water areas like bathroom, laundry rooms and kitchens.

• Acoustic Plasterboard - Due to its sounding proofing qualities, this type of plasterboard is preferred to be used in home theatres or noisy areas.

• Flexible Plasterboard - This is to be incorporated on curvy surfaces.

• Fire Resistant Plasterboard - Just like the name implies, this type of plasterboard is best suited for use in high fire hazard areas.

If you’re about to kick start some small renovations around your house or office, using a plasterboard to clad your walls is a very simple and worthwhile task. However, if you want to do major renovations or need to apply plasterboard to your ceiling, the best option would be to leave it to a seasoned professional.

how to lay loft boards?

How To Lay Loft Boards

Do you need more storage space in your home or property? If you live in a tiny space especially where extensions can’t be made sideways, why not look to the topmost area of your home and consider boarding out your loft to make it usable?

Boarding your loft can make for a fairly easy DIY project but like every other home improvement tasks, it requires some specific skill sets as well as knowledge for a successful construction. Therefore, we’d recommend you hire the services of a reliable professional in order to guarantee the best possible outcome, especially if you lack proper training or experience that’ll help you avoid some costly mistakes. Here, we’ll give you a good insight into the loft board laying procedures.

• Get The Right Tools & Equipment

The materials and supplies you’ll need to lay loft boards include loft boards, screws, tape measure and pencil, drill, hammer, saw, protective gear such as gloves and dust mask.

• Work Out The Area

Measure up the area you need the boards to cover. The standard loft features two different sizes (both are 18mm thick) which include 2400mm x 600mm and 1220mm x 320mm. You should ensure that the board you opt for fits through the loft hatch perfectly.

• Start Laying

Once you’re done working out the area, the next step is to put on your protective gear and start putting the boards in place. You should lay the boards in a staggered pattern so as to give a better strength. While doing this, watch out for any wire running through your loft so they don’t get trapped, you should also cut the boards for easy access to the light fittings’ top.

• Make It Permanent

Upon the successful placement of the boards in a way that offer a safe area to store things and stand on, you’ll have to screw them in place. Start by drilling 2 or 5 holes along the edge of individual boards in such a way that lines up with the centre of the joist below. Once done, then you can fix them in place with screws.
