Extensions- 9 Mar 2018
Kenny has just finished building a porch at my address. From the beginning, Kenny has been excellent with regards to providing advice, arranging the job to suit us and providing a very competitive and reasonable quote. Whilst on site, Kenny arrived early, was always extremely polite and the finished job was even better than we imagined it would be. On a scale of 1-10 we would honestly give Kenny an 11 and will definitely use his company again. Would definitely recommend him to others.

New on MyBuilder
Extension Builder in Marylebone, North London
Hi, I’m a skilled and reliable multi-trade construction specialist with several years of hands-on experience across a wide range of domestic building work. I originally started as a handyman and have since developed a strong all-round skill set through practical on-site experience. My main areas of work include kitchen fitting, bathroom installations (including toilets, showers and fittings), tiling, flooring, media walls, patios, and painting & decorating. I also have experience in general building and repair work, which allows me to take on a variety of projects from start to finish. I hold qualifications in bricklaying and plumbing from City & Guilds, which support the practical experience I’ve gained working on real projects. This combination allows me to deliver work that is both structurally sound and finished to a high standard. I take pride in being punctual, tidy, and easy to communicate with. I understand how important it is for customers to feel confident in who they hire, so I always aim to be clear with pricing, honest about timelines, and committed to delivering quality results. As I’m currently building my profile on MyBuilder, I’m focused on providing excellent workmanship and earning strong customer feedback.
