It depends on the size and type of extension. Small porches or flat roof extensions are very reasonably priced. More substantial two storey extensions can be expensive. In general, the price is roughly proportional to the amount of space you add to your home.

How much do Builder services cost?
How much do Builders cost? Prices for Builders in 2026 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.

Services offered by Builder
The tasks of a builder vary widely, however in general; builders are responsible for the coordination of different types of construction involved in erecting a structure or building a house, office or any other building. The architect, on the other hand, is assigned the duty of designing the structure and creating the blueprints while the builder will take charge of bringing the ideas to life by overseeing the construction process. In addition, a builder will be involved in getting any relevant building permits as well as consents and have the land surveyed to determine what would be required in the way of drainage and lots more. Once they have surveyed and prepared the land, the builder will kick start the building process. Generally, they’ll remain on-site throughout the building process so as to make sure that the structure is built the proper way and in line with the laid down plans.
For instance, during a new build, a builder will first supervise the laying of the foundation then the house frame being erected followed by the roof. Once done, they’ll then work closely with other tradespeople such as plumbers and electricians in order to get power as well as water to the house. Other tradesmen may be hired to complete various tasks. For example, a carpenter may be needed for the flooring, landscapers to take care of the front yard, painters to paint the entire house both interior and exterior and lots more. Due to the fact that a builder will have to organize all these tradespeople, they need to have a good understanding of these different fields in order to ensure that the job is done the right way and in the correct order.

Builder FAQs
With the prices of buying a house skyrocketing, many of us are tempted to building our own house. This is sometimes an excellent choice, but you will first need to understand the costs of building a house from scratch. As per a general estimate, the cost of self-build ranges between £300 per m2 to £3,000 per m2.
As you can see, this is quite a variation in price from lowest to highest. Location is a prime factor in determining the costs. Building a house in London and the South is more expensive compared to other regions. Aside from location, several other factors make up the price.
Self-manage with subcontractors
You hire professionals directly like builders and carpenters. You also buy all the materials yourself allowing you to get the best prices.
Hiring a main contractor with other subcontractors
You will first need a main contractor who will help to create the watertight structure for your house. For the rest of the work, try hiring out subcontractors. Make sure that you buy all the materials yourself to get the best price.
External cladding materials
If you are looking to install other external material other than brick, you will also need to factor in the cost for the same.
Here are some example prices:
• Render on blockwork costs around £25 per m²
• Timber cladding is around £25 per m²
• Hand¬made all-weather tiling costs around £54 per m²
• Rubble walling or flint is around £90 per m²
• Reconstituted stone costs about £48 per m²
• Natural stone is about £75 per m²
Make sure to include these costs when coming up with the estimate.
Roofing materials
Non-standard roofing materials tend to add more to the cost and therefore you will also need to account in for this factor.
Here are some examples:
Welsh slate – £60 per m²
Second-hand slates – £35 per m²
Handmade clay tiles – £65 per m²
Reed thatch – £80/m²
If you choose to add any unique material to your roofing, be sure that you remember to factor in its cost.
When Does A Loft Become A Habitable Room?
When a loft is being converted to functional space, there are a multiple options it can offer. It’s not uncommon that at the conversion of this space, many household may not have a specific plan on how it’s going to be used. However, they know later on an actual need might arise, perhaps as you start working from home, developing other hobbies that requires an extra space or the family grows.
The loft can easily be converted into a game room, study room, playroom or even a household’s “breathing space etc. However, when the family grows and you wish to make use of the space on the top of your home as an extra bedroom, there are many factors to consider. The fact is, just because there’s enough space to fit a bed, doesn’t make it habitable. For a loft to become habitable, it must be built specifically for the purpose of being a sleeping area and must also comply with the relevant building regulations. It’s as a result of this, many property sale particulars include “potential third bedroom, subject to regulations statement written on it as well as the boarded and insulated loft space’s dimensions.
Loft conversions building regulations are set in such a way to ensure that adequate attention is given to both safety and structural elements to build a new space that’s fit for undetermined household use. These regulations are established minimum requirements to guarantee the following:
• The new floor and ceiling’s structural integrity.
• The existing roof and party wall modification’s structural stability.
• Safety during fire incidents plus an escape route.
• An appropriate stairway access.
• The proposed changes’ structural suitability to the external environment in association with the local area as well as any unique factors specific to the property.
Damp issues on a property are usually generated by a lot of factors such as a poor or broken guttering, condensation and lots more. The question arising here is what is the possibility of External Wall Insulation (EWI) preventing condensation? Not only is EWI a reliable way to reduce condensation-caused damp, but it’s also one of the major reasons property owners in solid wall homes consider thermally rendering or cladding their external walls.
Condensation arises as a result of warm moist internal air hitting a cold surface such as the steaming up of both windows and mirror when having a shower. What happens here is the condensation of the water vapour in the air from a gas to liquid in the process of touching the cold surface - one whose temperature is significantly reduced to reach the dew point. At the dew point, condensation is very rampant, and to tackle this issue you’ll have to heighten the wall temperature in order to convert the moisture to vapour and permit it to pass through the wall. And that’s exactly the job of an external wall insulation!
To get started you must ensure that the walls are clean and dry prior to fitting the external wall insulation. The month of May through to September when the weather tends to be dry and more stable are usually the best period to carry out the project. The external wall insulation will function just like a cosy blanket around the building. Ultimately, changing the feel and temperature of the inside of your home. As a result, the previously cold walls will no longer be cold which goes a long way to mitigate the effects of condensation. Furthermore, when an EWI is installed, the rooms of your home will automatically trap more thermal mass as the heat is saved in the walls’ fabric and released back when the temperature drops.
In a nutshell, a mortgage loan is for the acquisition of an asset, so lenders won’t tend to give you anything else in a mortgage that is going to cover your home renovation costs. When you are applying for your mortgage, your provider will examine the price of your new household. For example, if you’re planning to buy a property for £200,000, but you need another £50,000 to help improve it, you’ll find that your lender might turn you down.
Essentially, with any mortgage loans that you take out on your possessions, the bank or creditor theoretically owns your home till you’ve entirely paid off your loan, which is why it is very unlikely that you will get extra funds from them. There are some mortgage providers who will be willing to add on some building costs, but it is entirely up to you whether to choose it or not.
With most mortgages, banks and other lenders will usually give you a maximum of 95% of what you purchased your property for. That means, that even if you contemplate the household has the probability to be valued at so much more, you’ll have to find an alternative way of paying for the developments you have in attention. So, if the accumulation of extra funds on to your mortgage loan is out of the question, you’ll need to find additional ways of paying for the home developments.
It is well and good if you have the cash saved up, or else, you can explore other payment options which your bank or lender may be able to help you with. There are several methods by which you can collect the cost to pay for the improvements, from personal loans to credit cards or even overdrafts, there are tons of ways to lending money. Keep in mind these are all forms of debt so keep an eye out for the interest rates when you are repaying.
Cement is a crucial element in bricklaying that’s widely used in both construction as well as finishing works. Generally, they’re used to aerate concrete blocks, connect bricks, prepare plaster, floor levelling as well as the making of precast products. The major reason cement is one of the most common construction materials as its incredible ability to hold structure together. To get a cement plaster, you’d simply have to mix cement with both water and sand. However, when you mix cement with lime, sand and water, you’ll get a mortar.
For cements mortars to be used inside joints, you’ll have to include 1 part cement at the minimum to not more than 2 parts sand by weight which should be dry mixed and moistened with enough water to allow for troweling and packing without falling apart. Generally, the cement sand ratio in a mortar is in between 1:2 to 1:6. The cement and sand mix ratio is largely based on the importance of the project.
Cement provides a plethora of uses in bricklaying and these includes:
• Preparation of cement concrete
• Preparation of cement mortar
• Building fireproof and thermal proof structures
• Building chemical proof structures
• Serving as a grout material
• Building hydrographic and frost resistant structures
• Manufacturing precast members
• Constructing aesthetic concrete
• Constructing cement concrete roads
There are several types of cements with each having its specific purpose. For instance, the type of cement more suited to building a fire proof structure is a high alumnia cement and to build a hydrographic structure, cements like expanding cement, hydrophobic cement, pozzolana cement and quick setting cement are the best bet. Acid resistant cements are more useful in building chemical proof structures, portland cements are best suited to making grout materials, while coloured cements are preferable to building aesthetic structures.
If you’re currently experiencing some structural issues with your building or property and you’ve heard a thing or two about the several benefits associated with getting underpinning done, you may be wondering if underpinning might just be the answer to your worries. Well, one thing you should when it comes to underpinning is the fact that, while there are some structural issues that may actually warrant an underpinning job, there are also some situations that can not be fixed by underpinning. In this post, we’re going to consider the events whereby underpinning of your house will be required. Let’s take a look!
First and foremost, you should know that underpinning isn’t required for issues related to slab heave. Footing movements which are likely to reverse normally occur when the content of the soil moisture changes unevenly which gives rise to slab heave. This movement results for a reversible effect.
Generally, underpinning is done to remedy problems related with the movement of the footings of a building or property, but as stated above – not all movements require underpinning. So, when is underpinning required? More often than not, a situation that’s resolved by underpinning is the event whereby the footings of a building or structure drops or subside as a result of some reasons that are irreversible. For example, footing movements caused by a footing set on a soft or loose soil which may be irreversible.
In the event whereby the footings of your house haven’t been installed as deep as required during the initial construction, then you will need to have your building underpinned to make it more stable. If you’re also looking to increase the load on your foundation like adding another storey, you may also need to have your house underpinned to support the extra weight added.
How Much Do Roof Rooms Cost?
The price of your roof room may vary depending on your location within the country. Other factors that can also play a key role in determining the price of a roof room includes the conversion’s type as well as the legal and technical issues it’s currently facing. Usually, the cost of roof rooms will range between £1,200 to £2,000 per square metre. The differences in the price per square metre is influenced by the size of the alterations to the roof, the type of roof room to be constructed, the access, location as well as the finishing type.
• DORMER LOFT CONVERSION.
Here, one of the slopes of a pitched roof is substituted for a box-shaped structure. The outcome is a flat roof space which enables the fitting of full sized windows as well as the incorporation of several appliances. This is quite expensive as it involves a total rebuilding of one roof pitch alongside the complete internal works that are associated. The average cost of a standard dormer loft project will range between £25,000 to £50,000.
• HIP TO GABLE LOFT CONVERSION
Here a vertical brick wall is used to substitute the roof’s slope at the ending part of the terrace on detached buildings. The average cost of this type of roof room will range between £32,000 to £60,000.
• ROOFLIGHT LOFT CONVERSION
This basically involves fitting rooflight windows in the roof. Other improvements include flooring, plasterboarding, strengthening of the existing floor, as well as installation of rooflights. The average cost of this type of roof room will range between £15,000 to £25,000.
• MANSARD LOFT EXTENSION
This roof room can create an extra storey on top of an existing building as it makes a space featuring two or four external walls that are a bit sloped. The average cost of this type of roof room will range between £40,000 to £70,000.
