There are many types of extensions. Many are a single store extension that extends the kitchen or living space. They come in many different styles – the very popular ultra-modern ‘box’ extension with big windows and roof lights, to extensions that matches an existing old dwelling. We have the experience and expertise to design and build your dream extension

From an attic conversion to full gut-out and re-do of the entire house, we can help plan and execute your home renovation project. If you are adding an extension, it might be the right time to do the other work in the house that needs to be done. From making the ground floor open-plan, to doing attic conversion or improving the energy efficiency of the dwelling.

Sharon Farrelly Blackrock

We’ve been wanting to do a side-return extension since we bought this house a couple of years ago but were struggling finding a partner that ticked all the boxes (value, architect design, building team, etc). When we met Space Extensions we were immediately impressed by the professionalism and later when the work started

Paul Gradock

Having considered a rear extension for a couple of years, the pandemic made us realise we needed more space. Space Extensions provided a very detailed quote with clarity on what was included and excluded in the cost. They provided contact details of work carried out by them in our area and after viewing a similar extension to what we wanted we decided to go with Space Extensions
