Extensions- 7 Jun 2026
Zilvinas and the team at Innovate Builders were outstanding from start to finish. We hired them to build our two-storey side extension. Zilvinas was open, professional, and fully committed throughout the project. He was always available to answer questions, offer advice, and guide us through each stage of the build. His team worked hard and delivered a high-quality finish, all while keeping the project on schedule and within budget. As this was our first major building project, we relied heavily on Zilvinas's expertise and guidance. His knowledge, practical advice, and problem-solving skills were invaluable and made what could have been a stressful experience feel smooth and manageable. We are absolutely delighted with the result and would not hesitate to recommend Innovate Builder. As I said it was our first ever big project, we had heard many horror stories but are so grateful to have found Zilvinas and his team.

Extensions- 8 Oct 2018
Alton and his team at Bluelime have been incredibly helpful and enthusiastic throughout our design and planning process. From the start, Alton took his time to understand our needs and propose several cost-effective ways to improve my home and create more space for my growing family. The design process was completed efficiently and submitted for planning permission, which was granted without a problem. Since then, his team have continued to be helpful and communicative despite my need to delay to the building works due to unfortunate complications with my freeholder.
