Additional cost to finish your open space extension

Surveys show that more than 8 out of 10 Irish homeowners want to either add a house extension or make some kind of home alteration to improve their lives. This shouldn’t be a surprise considering the present state of the housing market, but we’re all too happy to help. 

Whatever the type of extension you are looking to add to your home, we have the experience and the means to do it for you. Our cost-effective house extension building techniques are ideal for bedrooms, home offices, family apartments or granny flats and always fit your requirements perfectly. From a bedroom extension to a kitchen extension, we’ll turn your concept into a beautifully finished space without the hassle of moving house. 

So, just how do we do it? 

The most important stage of a house extension is the planning process as this is where we convert your input into a real, actionable plan. We know that clients who rush the design phase often end up changing their minds during the build, so we always make sure enough time and attention goes into getting every detail just right before we start building so that we can avoid delays, extra costs and pressure later on.

Next, we’ll help you assess any preparatory works that are needed. Successful home improvement projects begin with a thorough review of the house being extended. It may be necessary to improve the existing electrics and plumbing to optimise connections between your new space and your existing property. Other preparatory works may also be called for – for instance, if extending your space will involve alterations to the existing structure, you may need to renovate part of that to ensure a perfect match between both spaces, new and old.

Once the planning and preparatory work is complete, it’s time for the build to begin. As part of your house extension you can expect:

  • Project management resources
  • A construction crew including all relevant specialists
  • Foundations, frameworks and structures incorporating the latest materials and techniques
  • Full slider or bi-fold glazing
  • Finished electrics and mechanical connections
  • Architectural roof glazing
