In 2015, Studiolada Architectes (of Nancy, France) completed a 117 square meter home for a retired couple. On the firm’s website they call the project: Réalisation d'une maison individuelle à Baccarat. 

Here are two photos (1 exterior and 1 interior) via the architects:

Most of the house is finished in wood. It was a modest build costing 174,361 € in total before taxes. The house itself cost 146,506 € and the standalone garage cost 20,245 € (both before taxes). The balance of the costs seem to have gone to exterior landscaping.

If you consider only the house, that works out to be about 1,252 € per square meter or about 115 € per square foot. Speaking of reasonable.

What’s particularly interesting about this project though is that after it was completed the architects published what they call a dossier de synthèse en Open Source (click through to download) – effectively an open source file of all the project’s documents.

Included are all of the plans, assembly details, construction photos, and even the entire construction budget. The ambition was to build an affordable and sustainable house and then make all of the information publicly available so that others might replicate what was done.

I think this is great.

So I’ve decided to publicly commit to doing the same for my proposed laneway house. If and when it gets built, I will document and publish the entire journey – including all development/construction costs – and make it freely available on this blog and probably elsewhere.

I got a bit of flak (on the internet) for calling my laneway house a “prototype” project. But that’s truly what I want it to be for Toronto. Hopefully sharing more, rather than less, information will help it to serve that purpose.
