The cost to build a house can depend on a number of factors. It is important to understand each of these when making decisions for your self build project and in determining what will adhere to your budget.

1. Location

Depending on the location that you are building in, costs can differ substantially. Areas such as central London, tend to have the highest build costs in the UK.

Typical costs to build a house in Northern Ireland in 2018 can range from £90 - £100 per square metre.

2. Design

Everyone has different ideas about how their dream home will look. Inspiration is everywhere and it is inevitable that before you even hire an architect, that you have imagined every detail about how you would like your new home to look. Knowing the type of design that you want can help in determining its overall cost. Whether your style is traditional, country or contemporary with lower-budget or higher-end interiors, the design you choose can have a big impact on its overall cost.

You should consider talking to your architect initially about your ideas and budget as they will be able to advise you on suitable options for your self build.

When hiring an architect, it is important to consider if they have previous experience designing similar projects within your budget. Once you approve your plans with the architect, you should aim to find a builder who can offer a fixed-price guarantee for your project.

Statistics show that the majority of self build projects are completed late and over-budget. Having a builder who can develop a clear specification in terms of quality interiors such as; kitchens and bathrooms, could save you a lot of money in the long run.

3. Size

Not only does the location and design of your self build project affect the overall cost but, ultimately, the cost of your self build will be dependent upon the size of your house.

The size of a house is measured in square metres/floor area. In most cases, builders will provide a cost per square metre based on your design plans and also on the number of storeys you plan to have. A bungalow will ultimately be cheaper than a two storey home.

4. Build Materials

There are many options available when it comes to the type of materials used to build a house. The most popular types of construction materials used include; timber frame or traditional brick.

Different material options impact the final cost. Timber frame houses are usually built faster when compared to traditional brick builds. However, there is a perception that traditional brick builds are more expensive, when in fact, the actual cost variation between the two materials used in many cases may not be substantial. It is in fact the time taken to construct a house using a particular material that is more likely to impact the overall cost.

Understanding the pros and cons of using each type of construction material will help in making a decision on which is best to use.

5. Project Management

Lastly, it is one of the most important decisions you will make and likely to be the biggest influence on cost - how will I manage my self build project?

There are two options; you can manage the build yourself, and all of its elements, or you can hire a contractor to manage the project for you.

Although the cost to hire a contractor can have a very large impact on the overall cost, on the flip side, if managed in the wrong way by yourself or your partner, you could face more substantial costs down the line as a result of a poorly managed project. Successful project management is critical to your self build.

Don't be blinded by the savings that you could make by ‘going it alone’ and instead weigh up if you have the correct skills, knowledge, expertise and most importantly - the time - to effectively take on such a huge task. It could ultimately lead to the success/failure of your self build project.
