    Wrap around Extension

    Posted 29 January

    I recently had a wrap-around extension added to my home by Kosta & Sons Contractors LTD, and I couldn’t be happier with the results! The team was professional, efficient, and incredibly skilled from start to finish. They listened to my vision and delivered a seamless extension that perfectly complements the existing structure of my home. The quality of their workmanship is outstanding—everything from the foundation to the finishing touches was done to the highest standard. The project was completed on time and within budget, with minimal disruption to my daily life.

    Double storey side extension

    Posted 13 January

    Great company, competitive price, a builder you must get if you want the best quality of work. Was the most competitive on price as well. Guides you through the build process and fills the gap in your knowledge if you are missing it. Highly recommend Kosta and sons.

The attention to detail in the construction and finishes is outstanding, and the additional space has made a huge difference in functionality. The design maximizes natural light, creating a warm and inviting atmosphere. Overall, the extension has added both value and comfort to our property, and we would highly recommend pursuing a similar project for anyone looking to e

    Rear extension

    Posted 14 November 2024

    Great experience - Kosta was very kind and my kids loved him and asked when he would be working next! He was a very good builder and helped us at every phase of the job. He was the most competitively priced builder out of all the builders that approached us. He gave us ideas we would of never of thought before. I HIGHLY recommend this builder!
