In a nutshell, Marius and his team are great. They're kind, respectful and Marius is always available to answer every question you have - he def is the most knowledgeable builder I've spoken to. You get a very transparent estimate and sign a contract, for both parties' peace of mind. If extras come up, Marius openly discuss them with you before taking any action - my job required quite a few and Marius was also great to stay competitive price-wise whilst keeping the quality of the work sky-high.
