Welcome to X4 Construction – Complete Building and Refurbishment Services

Founded in 2005 as a small construction company, we have steadily grown and now have a team of creative construction and trade professionals.

We specialise in new builds, full refurbishments and high quality extensions. Creating and designing new living spaces with up to date kitchens and bathrooms fitted to high specifications. Sympathetic renovations of historic buildings and/or complete refurbishments.

We love working with challenges which need innovative thinking to make them work for our client’s needs. Looking for solutions and not being frightened by the unconventional. Thinking ahead and foreseeing possibilities to change. We don’t believe there is a problem that cannot be overcome.

With complete building and refurbishment services, we mean just this: We will guide you from start to finish, we can offer architects, design and structural engineer services and will help you to get your project off the ground.

We work hard to make the whole construction process as painless as possible by communicating, showing reliability, trust, and leaving a quality finish on time and budget.

If you are considering a renovation, have plans for an extension or designed a new build, we would love to talk to you!



About Us


Leo Sobol

Managing Director

Leo’s passion is still onsite, amidst the hustle and bustle of the building project. He is very hands on, on a day to day basis and guides projects, takes care of site visits and liaises with the clients. He has worked very hard to create a company which is well respected and trusted. Building a strong team has been very important because without them we can not deliver like we do.

Chantal Sobol

Managing Director

Chantal is the face / voice in the office and takes care of the design side of our projects. She works very closely with our architects, plumbers and electricians. She can help with sourcing and supplying sanitary ware, kitchens and lighting solutions, items which do not necessarily come off the shelf to create that special individual look.

Environment / Sustainability

Over the last 6 years or so we have been working hard with our clients to look for sustainable, recycled and natural products in their projects.

90% of our projects these days involve ground or air source heat pumps, solar arrays and if possible natural insulating materials. This sometimes means that zero energy amount is obtained from non-renewable energy or fossil fuels. The main goal is to utilise a renewable or alternative energy.

Our clients will have the choices to suit their criteria and budget on how their house/extension is going to be built. Our first choice is to encourage renewables where possible but we do understand also that budgets sometimes don’t stretch to have all the boxes ticked.

With sustainability and eco credentials in mind and as part of our commitment to sustainability, we only procure timber from well managed and legally compliant sources.
