At this time of this writing in the fall of 2022, housing prices are beginning to fall in Halifax. That is of course good news but the simple fact is that, when factoring in higher interest rates, housing remains unaffordable for far too many people in Nova Scotia. Rightfully, some people are looking for alternatives to the sky-high cost of housing and one such up-and-coming trend is that of shipping container homes. Sounds like a great way to build a home at a great price, right? Not so fast!
It certainly sounds appealing: a disused shipping container can be purchased for only a few thousand dollars and is constructed mainly of solid steel. They have literally been around the world multiple times in all weather conditions and are built to last. This however does not mean they necessarily translate to a solution to the housing crisis.
What’s Wrong with Shipping Container Homes?
The biggest issue is that they are small. They are a decent height for those not over 6’6” (like almost everyone but me) at 8.5 feet and are plenty long (usually 40 feet) but are a mere 8 feet in length. That doesn’t sound terrible until you consider that….
Homes Need Utilities!
A home is a complex system of interdependent components: electrical, plumbing (both supply AND waste) and heating, ventilation & air conditioning (HVAC) pipes that run behind the walls in all homes (and are required by all building codes)! This means that a significant portion of the interior space needs to be dedicated to these items, further reducing the living space. Speaking of HVAC…..
Metal is a Conductor of Heat AND Cold
When I was a teenager, I occasionally helped load shipping containers that were bound for various projects in Northern Africa. On one hot day, we measured 51 degrees Celsius inside the container! It was like being in an oven and while I wasn’t loading anything that day, I tried to see how long I could last. It was less than a minute before I started sweating uncontrollably and I had to leave.
Metal is a conductor both of heat and cold and we certainly get both extremes in Nova Scotia. Neither air conditioning nor high R insulation are required in our province, but I don’t see how one can survive without them in a shipping container That’s not even getting into….
Shipping Containers are (Not) Really Strong
Shipping containers are strong and heavy, right? Think about it: they are stacked 9 high on ships and face countless treacherous weather conditions in the open sea. However, unlike goods, people need windows and doors. You might think that it’s as simple as cutting a few holes in the steel, but the fact is that these containers are designed to transfer all the weight to the ends, so cutting a hole for a window requires structural reinforcement. Furthermore, many Engineers, Architects and Contractors refuse to work with shipping containers as they are not familiar with them (and that goes for home inspectors too!) and consider them too high a liability to work on.
An Important Disclaimer
I am NOT an expert on construction and shipping container homes and there are some advantages that I did not touch on. As well, you may be reading this in the future and this type of construction might go mainstream with improvements in construction techniques. I am just pointing out that in 2022, the cost savings can be quickly wiped out with all the expensive modifications required to make containers habitable.
I am in favor of anything that can make housing affordable to everyone on the planet but while on the surface this seems like the ideal solution there are too many disadvantages to this type of construction to consider it a viable option at this time.
