3 Different Types of Garage

The cost of a garage conversion will depend on the type and size of the existing garage.

Here are the three most common types of garage:

Integral Garage: In this case, the garage is inside the house and is the cheapest one to convert.

Attached Garage: An attached garage will have its own roof and several outer walls that will need insulating and/or reinforcing. These garages are the next most expensive option.

Detached Garage : Detached garages are different to the primary residence and therefore will certainly be the most costly to transform. It is better to build a new garage rather than use the old one.

Depending on the structure, you’ll probably need to add an extra wall to each side, insulate it, convert it to a tiled roof if it’s flat and install piping for fresh and waste water. The amount of work involved with detached garage conversions makes them prohibitively expensive.

Architects & Structural Engineer Fees

You really don’t have to employ an architect except if the conversion project is challenging or requires significant changes of the property. Expect their fees to be between 10 -15% of the total build cost if you do instruct an architect to draw up plans.

Structural engineers can give you estimations for sustaining steel joists that will be needed should you knock through a supporting wall. Their fees vary but for simple projects such as this one, expect to pay between £250 and £370. For much bigger projects that involve considerable remodeling of the existing floor space and several steel joists, expect to pay over ₤ 500.

Because you’re working with an existing structure, building costs for a garage conversion are minimal. There will be some major alterations to make, so before you start gathering quotes, consider some of the following points.

Average Cost of Garage Conversion – things to consider

But how much is a garage conversion? Well, there’s no absolute way of knowing without a proper and thorough assessment of your property, but generally speaking the final cost of a garage conversion will depend on a number of different factors, including the following:

The condition of the existing structure: If you need to modify the wall and/or the frame attaching the garage to the home, as this may increase the conversion cost by £5,000.

The room you want your garage converted into: The less expensive rooms are living rooms and bedrooms because they require fewer additional fittings and fixtures. On the contrary, new kitchens, bathrooms or utility rooms are much more expensive because access to water and electricity is more important.

The size of your garage :  The larger the garage space your are converting, the higher the cost as more materials and days of work are needed.

Hiring a project manager or an architect for your project: It might seem a pretty expensive option, but true experts  can help keep your garage conversion project on track, provide useful advice and help you save money.

The materials and/or labor you purchase and hire : It is also very important to hire a reputable company that can also advice you to buy the quantity of materials for your conversion project.

The height of the existing floor: If this is lower or not on the same gradient as the main section of the property, it will need to be adjusted accordingly, either with an extra layer of flooring (i.e. a cement layer) or via the installation of steps.

Walls: In most cases, an internal structure of stud walls will be built inside your garage to create your new room. Furthermore, in order to make the existing structure more energy efficient, insulation will be added between these walls. The average cost of a stud wall comes to £750, and your build costs will be determined by the number of walls that you need.

Windows: Windows and doors are both vital parts of making your garage feel like an extension of your house. The size, aspect and location of the room will find out how many are needed. On average, the cost of a door or window comes to £500 – £600, though you may pay more if you’re looking for high and bespoke premium quality finishes.

Floor covering: Even if you desire a luxurious carpet or are going to set up a wonderfully tiled flooring, you’ll most likely need to lay some brand-new concrete. This is usually required for old garages that the flooring’s unequal. Expect to pay around £1,000.

The position of existing utilities: One factor that might increase the cost of the project is having to run new utilities to your own conversion. Many garages have power, but most will not have water or gas. If you are changing your garage into a bedroom or living area, you will simply need to include a few more outlets into your budget.

But if you are arranging a grand new kitchen or bathroom, then gas and plumbing pipes might have to be set up. Including a brand-new electrical socket should not cost more than ₤ 100 but you can work out how to reduce the expenses, if more work is needed. Integrating gas or water pipes can end up being more costly, and if you require moving pipelines, the cost will be between ₤ 1,000 and ₤ 3,000.
