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.

Bricklaying- 26 Aug 2021
I cannot recommend Rob and his 2 sons highly enough, they have done an excellent job completing the brickwork for our large outbuilding in good time and at a reasonable price. 3 genuinely nice blokes who are hard working and thorough, we wouldn't hesitate to use them again and have already referred for work elsewhere.
