We are quite satisfied with the finish.
They guided us every step of way during building process and responded to us very quickly and nicely.
If we would have chance to do another addition, they are definitely the one we will look for.
Design - unbelievably helpful and professional throughout the design process. They offered suggestions and guidance throughout the whole design process.
Administration - great effort by all, especially as they were in transit to move their office to a different location.
Progress on Build - this was driven by an app and if you weren't familiar with using their app, they were available to answer questions, offer support and guide you through the app process. This was particularly helpful and appreciated when making adjustments.
Construction - the team of employees responsible for the construction were excellent. They were very organised and implemented all parts of the build efficiently. They are a credit to their company. Their communication was second to none as they always kept you informed.
Completion - our extension was completed on time and the quality was better than expected. This was contributed to the design, material used and the workmanship that by all - a great job - many thanks
