Factors That Impact Building Cost

It's essential to keep in mind that the cost of hiring a builder can vary significantly depending on the size and location of your home. Prices in urban areas, such as Dublin or Cork, tend to be higher due to increased demand and market trends.

Furthermore, larger extensions will generally have a lower per-square-metre price than smaller ones due to economies of scale. However, the overall cost may still be higher due to additional materials and labour required.

Other factors that can affect the cost of a house extension include the complexity of design, site conditions, materials used, and any necessary demolition or groundwork. To get an accurate price for your specific project, we recommend requesting a quote from our network of qualified builders.


Tips for controlling costs

  • Have a clear understanding of your budget and stick to it.
  • Work with an experienced, qualified builder who can provide you with accurate quotes and work within your budget.
  • Prioritise necessary features over luxury items. You can always add them later on when your budget allows.

Building a new house or undertaking a home improvement project is a significant investment that can greatly enhance your life. With proper planning, budgeting, and working with qualified professionals, you can make your dream home a reality without breaking the bank.
