Feedback From Our Valued Clients
We consulted your architects for a rear extension and couldn’t be more pleased with their work and result. Your team was very professional and communicative, and kept everything on schedule within our budget. They understood exactly what we wanted and delivered our desired finish. We highly recommend Vullcan if you’re looking for a reliable design and build contractor in London.
After speaking to several firms, we chose Vullcan to design and construct our loft conversion. Their team was very organised, clearly explained each step, and worked with planners to get everything approved. We’re absolutely delighted with our new space. Thank you for transforming our space beautifully.
Very pleased with the extension work they did on our Victorian terrace. The pricing was fair, and they completed all the services within their quoted budget. Would definitely recommend them and hire them again.
