What are the Main Factors Affecting the Cost of an Extension Per M2 in Ireland?

The cost of an extension per m2 in Ireland is influenced by several factors, such as:

The size and shape of the extension

The larger and more complex the extension, the more expensive it will be. For example, a two storey extension will cost more than a single storey extension, and a curved or irregular shaped extension will cost more than a rectangular or square one.

The design and style of the extension

The design and style of the extension will affect the amount of materials, labour, and time required to build it. For example, a contemporary and minimalist extension will cost less than a traditional one, and a flat roof extension will cost less than a pitched roof one.

The materials and finishes of the extension

The materials and finishes of the extension will affect the quality, durability, and appearance of the extension. For example, a brick and block extension will cost more than a timber frame one, and a hardwood flooring will cost more than a laminate one.

The location and site conditions of the extension

The location and site conditions of the extension will affect the accessibility, availability, and delivery of the materials and labour. For example, an extension in a rural area will cost more than an extension in an urban area, and an extension on a sloping or uneven site will cost more than an extension on a flat and level site.

The quality and experience of the builder

The quality and experience of the builder will affect the standard, speed, and efficiency of the work. For example, a reputable and qualified builder will charge more than an unlicensed and inexperienced one, but will also deliver a better and safer result.

What are the Hidden Costs of an Extension Per M2 in Ireland?

The cost of an extension per m2 in Ireland include some hidden costs that you may need to pay for, such as:

Planning permission and building regulations

Depending on the size and nature of your extension, you may need to obtain planning permission and comply with building regulations.

Professional fees

You may need to hire professionals, such as architects, engineers, surveyors, and solicitors, to help you with the design, planning, and legal aspects of your extension. The cost of professional fees can vary depending on the scope and quality of the service, but it can range from 10% to 15% of the total cost of the extension.

Contingencies

You may face unexpected issues or changes during the construction of your extension, such as delays, errors, damages, or extra work. This will require you to pay for additional materials, labour, or time. The cost of contingencies can vary depending on the nature and severity of the problem, but it is advisable to set aside 10% to 20% of the total cost of the extension as a contingency fund.

How to Save Money on the Cost of an Extension Per M2 in Ireland?

The cost of an extension per m2 in Ireland can be quite high, but there are some ways to save money on it, such as:

Do some research and compare quotes

Before you start your extension, do some research and compare quotes from different builders and suppliers. This will help you find the best value for money and avoid overpaying for underpaying. You can also use online calculators and estimators to get a rough idea of the cost of your extension per m2 in Ireland.

Choose a simple and standard design

The simpler and more standard the design of your extension, the cheaper it will be. Avoid unnecessary features, such as curves, angles, or bespoke elements, that will increase the complexity and cost of the work. Stick to a rectangular or square shape, a flat or low-pitched roof, and a standard height and width.

Use cheaper and recycled materials

The cheaper and more recycled the materials of your extension, the cheaper it will be. Opt for materials that are easily available, durable, and easy to install, such as timber, metal, or concrete. You can also use recycled or reclaimed materials, such as bricks, tiles, or windows, that will reduce the environmental impact and cost of your extension.

Do some DIY work

The more DIY work you can do, the cheaper it will be. You can save money on labour costs by doing some tasks yourself, such as painting, decorating, or landscaping. However, make sure you have the skills, tools, and time to do the work safely and properly, and leave the technical and structural work to the professionals.
