GKB did a gut renovation in our pre-war apartment and we could not have been happier with the results. The project was completed on time, communication was always open and clear and the quality of work is outstanding! From the initial interview with Jonathan, we were impressed by the process, professionalism and the service level. Through out the planning and renovation, Jonathan and Peter made sure we were up to date on the progress, stayed within the budget and were accommodating our needs. There were no delays and no issues. The team never took any short cuts and the quality of work is very high! Jonathan did a great job advising us on many decisions that made our apartment better and more comfortable.
