Recently we employed OBK Developments to carry out renovation work to a rental property of ours which had been left in terrible condition by the previous tenants.The lads at OBK did a fantastic job at refurbishing the property. The house was transformed from top to bottom with the work being carried out in a professional and efficient manner.

Due to a growing family and the need for extra space in our home we decided to convert our attic space. We employed Aidan from OBK Developments to carry out the work and couldn’t be happier with the results. He looked after everything from getting the plans drawn up at the start of the job to decoration at the end. We are delighted with how it turned out and will definitely look to OBK if we need any work done in the future.
