London is southwestern Ontario's largest city and regional hub, with a construction market that spans new residential development in the north and east ends, established neighbourhood renovations throughout the core, and a significant commercial sector anchored by health care, education, and light industrial.
Building permits in London are issued by the City of London Building Division. Our stamped mechanical drawing packages are formatted for their requirements. London's design outdoor temperature for CSA F280 heat loss calculations is approximately -19°C to -21°C — consistent with much of southern Ontario but slightly colder than the lakeside GTA communities due to London's inland location.
London's residential new construction market is active in the north end (Sunningdale, Hyde Park) and east end (Riverbend, Kilally Meadows), where production and semi-custom builders generate steady demand for mechanical permit drawings. The renovation and addition sector in established London neighbourhoods — Old South, Byron, Oakridge — produces regular work as well, often involving mechanical system upgrades in older homes.
London's health care and education sectors generate commercial HVAC design opportunities — medical clinics, dental offices, and administrative spaces are a regular part of our commercial work in the London area. Restaurant fit-outs in the downtown core and Old East Village are also served by our commercial HVAC and make-up air design services.
