Extension Builder in Lower Holloway
Hello, my name is Henry, I am a 25 year old bricklayer from South east London. I wanted to become a bricklayer after learning of the history behind the bricklaying, particularly Victorian bricklayers. I often look at old buildings and think of what an honor it would be for future generations to look at my work in years to come and be proud of their ancestors' craftmanship, built with care and attention to detail that will have withstood the test of time.

Architecture- 27 Nov 2017
I contacted Marius because he had good reviews and wanted someone reliable and capable so design a single story extension with large external and internal bifold doors. I wasn’t disappointed - Marius has been excellent throughout the whole design process and produced drawings to a high standard which met our requirements. Marius was an excellent communicator and always available to give advice when required. Further more, he went out of his way to contact local authorities regarding any questions I had at no extra cost to clarify any uncertainties. I would highly recommend his architectural services - he was good value and very professional.
