    What Our Clients Say

    Pablo and Pilar, House Extension and Refurbishment in Welwyn Garden City

    ⭐⭐⭐⭐⭐

    “We hired LBH, led by Lewis Hammond, for a full house extension and refurbishment. It was a big project, and Lewis was honest, professional, and flexible throughout. He stuck to the agreed budget, discussed any extras in advance, and his invoices were always clear.He helped us with design choices, was always polite, and even supported us with maintenance jobs after the project was complete. We’re very happy with the result and would definitely work with him again. Highly recommended!”
