The construction sector is oversaturated with qualified companies, but none can offer the same calibre of care as John Building Service. Delivering exceptional services to residential clients across London for over 13 years, its team has demonstrated to homeowners the true value of a partner who shows up and completes the work as promised, without ever cutting corners or compromising quality. We heard more from Founder and Managing Director Ionut Jitariu, also known as John Jitariu, as his company is named in the Greater London Enterprise Awards 2026. Best Residential & Commercial Building Contractor 2026 & Loft Conversion Specialists of the Year 2026 John Building Service is a London-based residential building company specialising primarily in home extensions, loft conversions, and full refurbishments. Working in close collaboration with a tight-knit network of professional builders and subcontractors, the company has been dedicated to high quality finishes and great attention to detail for more than ten years. As a result, John Building Service has built a legacy of countless completed projects and happy customers across London. In the beginning, John Building Service was a much smaller operation. Over the years, however, Ionut has built a strong team, taken on much bigger and more involved projects, and put better systems in place to ensure that everything runs smoothly. Whilst the business has steadily grown and evolved, Ionut has strived to ensure that this advancement never comes at the cost of the essential elements that make up John Building Service’s DNA. “We believe in being honest with clients, doing what we say we’re going to do, and taking pride in the finished job,” he told us. “For me, it is important that we don’t grow just for the sake of growing. We want to take on the right projects, look after our clients properly, and make sure the quality stays high. There are plenty of building companies in London, so we don’t want to be the company that promises everything just to get a job.” Communication lies at the heart of this ethos. Building projects can be incredibly stressful for homeowners, and John Building Service recognises the importance of keeping the client informed and the project on track. The team reacts to problems with unrivalled speed and precision whilst prioritising total transparency from the very beginning: being clear about what can and cannot be done in the project, providing estimated costs, and detailing how the process will work. As with any industry, construction has faced its fair share of challenges in recent years. John Building Service has paid close attention to the landscape as material prices shoot up, deliveries become more and more unpredictable, and the task of finding good, reliable project partners is near impossible. Though these obstacles have been difficult for companies across the sector to overcome, John Building Service has allowed them to drive the advancement and enhancement of its operations. “The main thing we’ve learned is that you need to plan ahead; you can’t just wait for a problem to happen and then try to sort it out,” Ionut shared. “As the company has got bigger, we’ve also had to get more organised behind the scenes. When you’re smaller, you can keep a lot of things in your head and just deal with them as you go. That doesn’t work when you have several projects running at the same time.” The remainder of 2026 will see the John Building Service team continue to focus on undertaking a wide range of residential projects across London whilst building its strength in extensions, refurbishments, and loft conversions. For Ionut, this next phase is about growing at the correct speed without losing the aspect that have earned John Building Service its status as the Best Residential and Commercial Building Contractor 2026 and the Loft Conversion Specialists of the Year 2026. “We’re really proud to have won two awards at the Greater London Enterprise Awards 2026,” Ionut concluded. “Winning an award for a second year running is a great achievement for us, but the loft conversion award is especially nice because loft conversions are such a big part of what we do in London. They can be quite complicated projects; you’re working with an existing house, so there are often structural issues, access problems, and lots of things that need to be worked out along the way.” He continued, “We’re very proud of the team and of the reputation we’ve built over the years. Awards like these are great recognition but, at the end of the day, the most important thing for us is still having a happy client who is pleased with their finished home and would recommend us to someone else.” Contact: Ionut Jitariu Company: John Building Service Ltd Web Address: www.jbsbuilding.co.uk
