Overall i am very very happy with my tiny new home which i refuse to call a granny flat! Right from the beginning of the planning phase the team were attentive to my needs, ask questions and double checked at many intervals to make sure this custom space would truly fit my needs. I was able to request customised alterations which were always met with a can do attitude and accommodated with a smile. The team of workers in all aspects of the ground works right through to the finishing touches were exceptional tradespeople and craftsmen and were all very friendly and attentive. Theres no doubt that the time the team spent on site was pleasant and the workers became additional family for a period of time. The end product is amazing and completely individualised to meet my needs. All of the customisations i made suit me and look incredible. My only disappointment is that the planning phase did take a while due to logistics and it felt like a bit of a slow start to the process, however this is definitely a case of good things come to those who wait and we were fully informed about any arising issues along the way. I would like to make a special mention to Carl who tirelessly oversaw the project and made it his business to check in with us every step of the way. The personal touches were eternally appreciated.
