Overall excellent - our loft conversion was planned and completed within the 3 months timeframe; no delays whatsoever. In fact the actual building work super quick yet good quality. Disruption to us was minimal considering the size of the project. Communication with our project manager was quick throughout the project, e-mails answered very efficiently. Overall I would have minor comments for improvements - some health and safety issues such as leaving tools lying around or occasional errors in communication with one contractor who did not speak sufficient English, but the quality of the work was excellent throughout. We have already received very positive comments from friends and family who were impressed with the new loft and we ourselves love it. Highly recommended
