"We used Orama to dig out and lay a paved garden area. Costas is very approachable and really helped us with the choice of paving and layout. His team were hardworking and efficient and we were kept informed at each stage i.e. when materials would be delivered and removed debris would be taken away. We thoroughly recommend them."
