Granny Flat Logo


Concrete Built, built to last. This company is Irish owned company. Lee the owner manages the full process to ensure you, our clients are completely informed through the whole process. We also only ever have 2 builds on at same time and are strict about timelines, we normally have a 2 month waiting period from time of deposit. However Lee spends this time with you on design to ensure when we start building all involved are clear about what we expect. It takes about 8-10 weeks to complete a build, remember these are proper homes and building correctly takes time. However our guys are skilled and cause very little disturbance.

In order for these Granny flats to be planning exempt we build these, as home extensions, with a few other conditions. We build them in a clever way and each build has its own separate door for access. If at any stage in the long-term future you need to reconfigure this space as part of the property, perhaps for resale you have now the space to do so, potentially increasing your homes value.
