Wraparound Extension
Exceptional service from all at Gal Group. Special mention to Seb and Jonny who genuine cares about high quality workmanship. Did a wraparound ground floor extension. Projected lead time was 4-5 months and they completed in 3 months. Overall, very satisfied with everything from beginning to end. Definitely recommendVerified reviewerJob location: IG610 Builder

Extension and garden landscaping
I could not have hoped for a better team than with Sebastian and Johnny. Always on time, well organised, polite and helpful with myself and the neighbours. They completed in a record time all our garden which was entirely levelled, all drainages, foundation and structural works up to DPC level of the extensions. Strongly recommend them. Will call them again.Verified reviewerJob location: RM310 Basement / Cellar Conversions

Basement renovation works
We contracted Gesas-Ambition to carry out basement renovation works at our property in New Cross, SE London. This included internal structural alterations, new drainage associated with bathroom and kitchen, carpentry and finishes. From the onset, they were very organised in their tender submission, which was thorough and competitive. We were impressed with their management of the project, communication for the duration, and ultimately, the final product. We would certainly work with them again and are pleased to recommend them.Verified reviewerJob location: SE1410 Demolition

Complete refurbishment of a 3- bedroom bungalow house, including full kitchen and bathroom remodel
From the initial consultation to the final handover, Sebastian and Jhon along with the Gesas-Ambition team were nothing short of outstanding. We approached them for a major overhaul of our dated family home, which involved gutting and redesigning the interior spaces while adding a modern driveway . Despite some unexpected challenges like hidden structural issues and weather delays during the driveway phase, they handled everything with professionalism, and innovative solutions that stayed within our budget. We’ve already recommended them to neighbors and would use them again in a heartbeatJob location: IG8
