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 do roof rooms cost?

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.

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.

how much does a garage conversion cost?

Are you looking to create some more space in your home with your garage being almost dispensable? If yes, then considering a garage conversion project may be the way to go. Unlike many other extension options, garage conversion does not take up an additional space as it only changes the current structure of the garage. As a result, the cost of completing a garage conversion project can be relatively attractive when compared to other space creating alternatives. So exactly how much would a garage conversion project cost? Well, there’s no precise answer for this as several influencing factors come to play. However, in this guide we’ll give you a rough idea of the average costs that you’re likely going to encounter. Some of the factors that can influence your budget dramatically includes the following:

• The size of the conversion. The larger the size of the garage per square feet, the more cost you’ll have to expend.

• The type of your property - listed buildings are usually more expensive.

• Your location in the UK. If you stay in London where there’s a higher demand, you’ll most likely pay more.

• You’re likely to pay more if a specialist knowledge is required.

• The amount of glazing to be installed

• Quality of the materials to be incorporated.

• Quality of the professional to carry out the installation service.

On average, when it comes to garage conversion projects, you’re likely to pay the following depending on the per square metre given:

• A single garage of about 15 square metre will cost within the range of £6,000 to £15,000.

• A double garage of about 30 square metre will cost within the range of £12,000 to £30,000.

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.

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.
What qualifications should a builder have?

Some individuals who have been in the construction department for many years may not be qualified, that is, they may not have undergone an apprenticeship and/or trade certificate courses, but they might still be very skilled at their work. However, anybody can pick up a sledgehammer and demand themselves a builder lacking any skills or training. The wise thing would be to ask the builder coming to your house about what qualifications they have and what training they have undergone.

Licensing of building practitioners

You can now check if your builder or tradesperson is a licensed building practitioner by using an electronic public register which has a record of every registered builder. Being licensed provides you with an assurance that the builder who is about to do your work has proven his shill to the government and earned his right to be a practitioner. If you wish for certain important building and design work on your home it is imperative that you hire a licensed practitioner, the act is very common when you compare the scenario with when you have to call a plumber or an electrician regarding any work.

In order to become a builder in the UK, you must complete an apprenticeship or an NVQ. NVQ is another popular route to becoming a builder. You can also get your NVQ even when you are working as an apprentice. You can also make it based on any recognised overseas qualification.

All associates maintain a Code of Practice and Conduct which sets the standards for all stages of the building procedure. The Code requires builders to:

• Submit quotes on projects for which they have time.

• Securing the contract with a sufficient insurance cover.

• Maintain honesty and integrity at all times.

• Obey the law and industry standards of conduct.

All members of the construction association must also follow a code of conduct. As a consumer, if you think your builder has breached the Code of Conduct or the Code of Ethics, you can file a written against him or her.

✓ Your kitchen extension must not be over half of the area of land around your main house.

✓ The kitchen extension must not be side elevation onto a highway or forward of the principal elevation.

✓ The extension must not be taller than the highest part of the roof.

✓ The height of your kitchen extension must not go beyond four metres.

✓ Kitchen extension that’s more than one storey must not go exceed the rear wall of the main house by more than three metres.

✓ Two storey kitchen extensions must not be closer to rear boundary by anything less than seven metres.

✓ The kitchen extension must not include balconies, verandas or any raised platforms.
