"MSJ recently completed the ground floor extension and full renovation of our Victorian Terrace House. Connor, Ian & the site team were great from start to finish, always very responsive to questions/queries and delivered on the deadlines they set. We'd happily work with MSJ again for future projects."
"We recently purchased a house in Greenwich and engaged MSJ to completely redevelop the living area and I cannot recommend MSJ enough. Both the quality of work and service we received were phenomenal, we will be using them again. ... Lastly I'm an incredibly specific and sometimes difficult client when it comes to both finishes and my demands, no one batted an eyelid and the work exceeded my expectations at every turn."
"We have just had the pleasure of working with MSJ on remedial structural work of a Grade II Listed property in Walworth. Connor and his team were extremely efficient, helpful and dedicated to getting the job finished on time and on budget. Communication throughout was superb."
"Thank you MSJ for transforming our home! Having been let down by previous builders we were looking for reliable and high quality which we got from Connor and Ian & Team. ... Connor and Ian are both great genuine guys providing advice and ideas to have finished to a high standard."
"Fantastic work from Conor, Costa and the team, complete renovation on the house to an extremely high standard! Would recommend MSJ highly, the best in South East London!!"
"MSJ refurbishment. The whole team worked incredibly hard and to the highest standards to bring the design concept to life around the hectic schedule of our family life. Having you work at our house to make it our home was an absolute pleasure.Thank you!!"
