  • Monday – Friday: 7:00am – 7:00pm
  • Saturdays: 9:00am – 7:00pm

Because of the tight space and accessing most cases there is no other way. However, we are always aware of others and do our best to make sure everyone on site is mindful.

How do I get services to the laneway suite?

Getting the services to laneway homes can be tricky as most laneways themselves don’t have the infrastructure. These include water, drains, gas, and hydro, which tie into either the main house or directly to the street. Running the services underground to the street in established neighbourhoods can become costly and why it’s rarely done.
