  • Hi there just a bit about me. Well I’m a time served Carpenter / Joiner by trade and have worked my way up to now owning and running my own company’s for the past 25 years. I have employed up to 20 employees at any one time and build projects from £20k up to £12m for individual clients. So i know how to run a construction company and how to get the job done, but more importantly i believe i understand the stress and pressure all clients can endure if there build is not built within budget and within an honest time line. Everything we do is insured to the highest standards and our workmanship is second to none. I have decided to now move away from the large build sector and back to the smaller more personal builds as this is where i get the most satisfaction and believe I can offer the best service to the client, a happy client is a happy builder. Our work area is anything to do within the construction of your home, even down to the design and getting engineering across the line. Best regards Rod Moran
