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

Can I extend my barn conversion?

Generally, it’s possible to extend a barn conversion, but there are certain conditions that you’ll probably need to meet. Ultimately, it’s up to your local planning office to decide whether to approve your planned barn conversion extension or not.

Typically, small extensions on the side of a barn conversion are often approved, particularly if they serve to preserve the original character of the barn. This could be because the extension will mimic the appearance of the original structure, or house facilities that would look odd in the original building.

However, you probably won’t be allowed to build a larger extension, or one that isn’t in keeping with the appearance of the original barn.

what is a garden room extension?

A garden room extension, also referred to as Sunroom or Solarium, is basically a stand alone garden building that’s totally detached from the home. They are typically semi-glazed building that features a tiled roof rather than glass. What would have been good examples of garden rooms extensions include conservatories, orangeries as well as pool houses, however they are constructed with the help of different materials and features which ultimately makes them different to garden rooms.

Garden room extensions are built with the major purpose of adding extra functional living spaces for a wide range of room options such as a second living room, dining room, study space, home garden office or a rehearsal space - the options are numerous. In other words if you’re looking for an additional usable space within your home or property, a garden room extension can be designed to suit your needs. So whether you need comfy sofas for evening relaxations, a sturdy office desk for work or large dining room table for dinners with family and friends, a garden room extension can be all that you need to achieve to your living space goals or just to add more value to your property.

Garden rooms extension has multiple alternatives such as a conservatory, garage conversion, loft conversion, extension and garden rooms. However, it has some great benefits over its alternatives. These benefits include, being very cost effective, hassle free, can be built within 5 to 9 days, rarely requires planning permission, does not require building regulations approval, includes a full professional installation and management without any need for subcontractors, modern and unique as well as being very versatile. Overall, if you’re looking to create an additional space in your home without having to break the bank, then garden room extensions may be your best bet.

Is external wall insulation safe?

With the numerous benefits that comes with the installation of an external wall insulation in a building, it’s also important to find out whether it’s also safe before proceeding to fit one in your home. Firstly, to ensure that external wall insulation systems are safe, they must be BBA approved, which means they’ve been subjected to a thorough testing by the British Board of Agrement and therefore, suitable for use in UK homes.

Given the fact that cladding materials have recently generated a lot of debate and negative press about how reliable some particular materials are, questions are being asked of the safety and reliability of external wall insulation. However we must clarify that, although external wall insulation can be classified under cladding, it is very different to rainscreen cladding - which caused the Grenfell fire tragedy.

External wall insulation is completely safe. However, when it comes to fire, the safety of your system depends largely on the insulation type in question. The safest type of insulation you can have installed is the Rockwool insulation boards which are rated as Euroclass A1 non-combustible. The board is specially designed in such a way that it contains fire - preventing it from reaching the other areas of the building. They also do not produce harmful emission or smoke when impacted by fire.

Meanwhile, the Wood Fibre, is also a great insulation which is known to char and not burn. Contrary to many beliefs, it actually burns slowly creating this charring effect which produces an oxygen barrier that helps reduce the spread of fire.

To make your system safer, you can also make use of Fibreglass Mesh for reinforcement. It helps to improve the strength of the tensile which promotes the security of the boards attached to the wall.

how much value does a loft conversion add?

When its impossible to build out and create more space sideways, why can’t you look upwards? As more and more homeowners in the UK are carrying out their loft conversion project, one question that keeps popping up is the amount of value the loft conversion can add to their homes. However, this is a question that is impossible to provide a single and precise answer to. This is because the value that’ll be generated by a loft conversion is largely dependent on a wide range of influencing factors. To give you a vague idea of the loft conversion value to a property, we’ve put forward a research carried out by industry experts so you can know what you’re in for.

Nationwide carried out a research which shows clearly that a loft conversion including an additional bedroom as part of the building plan will increase a house’s value by up to 21 percent. Since the number of rooms a house has is one of the main metrics for house valuations, loft conversion comes in pretty handy as it’s a great and easy way to convert your house from a 4 bedroom house to a 5 bedroom house prior to sale.

Apart from the financial value aspect, loft conversion also adds more value to your lifestyle which is very unlike nearly other financial investments you can make. More space in your house automatically means more storage or a new room as you wish. A new room can be for a growing family or probably to serve as a guest room. It can also be used as a study space or even an office especially with the rapidly growing rate of people working from home. With loft conversion, the possibilities in terms of value are simply endless!

how to render a wall?

Wall rendering is basically a process which involves the application of sand, cement or polymer covering to a home’s exterior in such a way that enhances its look while also offering an improved stability. The process is a perfect solution for several exterior concerns mainly due to the support its able to provide. It’s highly beneficial for older homes whose walls may suffer from poor quality because of wear over time, while it’s also greatly advantageous for newer homes as it increases their stability while also enhancing their visual appeal.

Knowing how to apply render is a great skill to have with your home’s upkeep in mind. The project can be done quite easily by any competent and confident DIYer. However if you lack any of those attributes, then we’d recommend you get in touch with a reliable professional for help. In this article, we’ll take you through the wall rendering process.

✓ Prepare the walls. This involves examining the wall, repairing any structural defects as well as stabilizing any movements to prevent the render finish from failing.

✓ External details. This includes the removal of bargeboards, rainwater, soil pipes, alarm boxes and all other external details.

✓ Insulation. In the event whereby external wall insulation is to be fitted, this is the stage to do so.

✓ Developing a foundation for the render to fix to. Apply a render mesh over the insulation, bedded into the first base coat layer of render.

✓ Building up the render.

✓ Render finishes. There are a wide range of colour options as well as various finishes available from very smooth to textured. However, you should note that thin coat render systems are usually designed to be self coloured.

✓ Final finishes. This involves the re-application of the external rainwater, soil pipes and the other external details.

what is a dormer loft conversion?

A dormer loft conversion is a type of loft conversion that’s built making use of a roof’s existing slope. In other words, it’s an existing roof’s extension which is constructed in such a way that allows for an additional floor as well as head room especially suitable for lofts lacking good amount of usable space. The dormer loft conversion is simply an addition to the existing roof looking much like a box-like build constructed onto a pitched roof as it creates walls that are vertical to the slope while also being 90 degrees to the floor.

This type of loft conversion is the most common amongst homeowners in the UK mainly because it represents a cost effective means through which you can add an additional usable space to your home or property. The structure extends for the slope of the existing roof and can easily be altered to suit various tastes or styles. Furthermore, if you’re looking for a type of loft conversion that aids to foster reduced disruption to work, then dormer loft conversion is also your best bet. This is due to the fact that the structure is built from a scaffolding made outside a home.

There are different types of dormer loft conversion and the one which will best suit your property will depend on the property type, be it detached, semi detached or terraced as well as the existing roof shape and size. The dormer loft conversion is a popular choice for a lot of homeowners for a variety of reasons. Let’s have a look!

✓ It’s very cost effective

✓ The dormer loft conversion does not require planning permission so far it complies with certain conditions and limitations

✓ It adds an extra headspace as well as floor space.

do you need an architect for a garage conversion?
Have you decided to convert that under-utilized space ( garage) in your home to a more habitable space where you can do anything asides general storage or parking a car? If yes, then you’d probably want to know where to start or if you’d require an architect to get started. Well, you’re not alone! This is one of the most frequently asked questions when it comes to garage conversions and reasonably so. Talking about where to get started, when it comes to home improvement projects the first step to take is determining whether or not you’d require a planning permission or if your proposed garage conversion is covered under permitted development rights. Once you’ve been able to conclude on that, the next step is deciding whether you’re going to complete the project yourself, hire the services of tradesmen or employing a builder. And this ultimately brings us to the question of whether you’ll need an architect for a garage conversion. To get started, it’s highly recommended that you employ the services of a professional architect or an architectural technologist to assist in designing your garage conversion. However, most garage conversion projects are straightforward with no complex changes to be made so far you wish to avoid applying for a planning permission and staying within the set guidelines of the permitted development rights. In such events, if you’re properly trained and well experienced in the field, then it may be cost effective to design your garage conversion by yourself. It should, however, be noted that it all depends on your personal preferences and budget. If you’re on tight budget and don’t mind a straightforward design, you can save cost by not hiring an architect.
How much plasterboard do I need?

How Much Plasterboard Do I Need?

Although many people especially contractors have a tough time estimating the number of drywall or plasterboard needed to complete a project, it’s a rather simple task if all factors are taken into consideration. If you’re able to follow the same procedures taken by professionals to count dry wall sheets, you’ll be in the right direction. Let’s have a look at the procedures to follow!

lTake Square Footage Measurement

• Measure the square footage of the area where the plasterboard will be fitted.

• Multiply the height by the width of each wall or ceiling area.

• Add all quantities to obtain a total square-foot amount.

lCalculate Drywall Sheets

• To calculate the number of drywall or plasterboard sheet is very simple once you’ve gotten the total square footage.

• To get started, simply divide the total square footage of area by 32 (that’s if you are using a 4 by 8 sheets) or you can also make use of 48 to make the division (only if you’re making use of the 4 by 12 sheets).

• The answer you get after the division will give you the full number of plasterboard sheets that’s required to complete the project.

We’d recommend you include an extra 10 to 15 percent of whatever you calculate to take care of the possible odd cuts and wastages. This implies that if your total area is 1600 square feet while incorporating 4 by 8 sheets, simply divide 1600 by 32 which equals 50 sheets, now take 10% of 50 which equals 5, then add back the 5 extra to the 50 sheets earlier calculated to get 55 sheets. If you wish to estimate the cost, simply multiply the number of sheets gotten by the price per sheet. Do not forget to include delivery charges and local taxes.
