Nearly twenty years of plans brought to life, from a mother-son duo to a full firm, in Saint-Hyacinthe.
A story of continuity.
From Sandra Rioux's drawing table to a full team, each step built the next.
2007
The foundations
With over 25 years of experience in architectural design, Sandra Rioux founds Dessin SR in Saint-Hyacinthe. Her mission: to design custom residential plans that meet each client's needs, budget and lifestyle, from bungalows to chalets, up to high-end multi-unit buildings.
2021
The next generation
Vincent Fontaine, her son, joins the firm as a partner. Self-taught and passionate about 3D design, he brings fresh energy: output goes from two to about ten plans a month, the team grows and the firm enters full expansion.
2022
L'Établi is born
Sandra hands the reins to Vincent, who reshapes the firm in his image while preserving the expertise and rigour that built its reputation. Dessin SR becomes L'Établi Architecture: a young, innovative vision driven by one conviction, new build or renovation, nothing is too big or too small.
In a single year, some fifteen architectural technicians and newly graduated technologists join the team, which moves into new premises in downtown Saint-Hyacinthe.
Today
Large-scale projects
L'Établi leads large-scale projects across the Montérégie and the Saint-Hyacinthe area: real-estate developments of several hundred units in Léry, Varennes and Sorel, high-end custom homes, and projects delivered in collaboration with architects.
Every mandate is a chance to be creative, to find innovative solutions and to guide the client from the first pencil stroke through to completion.

Privacy policy
Last updated : octobre 2026
At L'Établi, we take the protection of your personal information seriously. This policy explains what information we collect, why, and how we protect it, in accordance with Québec's Act to modernize legislative provisions as regards the protection of personal information (Law 25).
Information we collect
When you fill out our contact form, we collect only the information you give us: your name, email address, phone number, the details of your project and, where applicable, the files you attach.
We also measure how the site is used, with Google Analytics: the pages viewed, the date and time, the page that brought you here, your device and browser type, your language, and an approximate location derived from your IP address. That IP address is not retained.
This measurement places a cookie on your device. It is used to tell one visit from another and to know whether you come back, which tells us whether the site is useful. It contains neither your name nor your contact details, and it cannot follow you onto other websites.
It is on by default and we do not interrupt you to ask for it: this is an internal measurement, used neither to target you nor to resell you. You can decline it at any time with the button below, and your refusal takes effect immediately.
If you arrived through an ad and have accepted advertising cookies, we additionally keep the technical identifier of that click. This identifier is assigned by Google or Meta; it contains neither your name nor your contact details.
Purposes
This information is used to contact you, answer your request and follow up on your project.
Browsing data is used to measure site traffic: how many people visit, which pages are useful, where the journey breaks down. This measurement serves to improve the site.
Where you have consented, it is also used to measure the effectiveness of our advertising, meaning which ad led to your request and what it cost us, so that we can decide where to place our advertising budget.
Your information is never used for advertising mailings or newsletters, and it is never sold. We also do not use it to show you personalised advertising elsewhere on the web.
Cookies and consent
Two things place a cookie on this site, and they do not follow the same rules. Traffic measurement, described above, is on by default and can be declined with the button above. Advertising measurement, which links an enquiry to the ad that produced it, never starts without your agreement.
For advertising measurement, a banner asks for your agreement on your first visit. Declining is as simple and as visible as accepting: both buttons sit side by side and carry equal weight, and nothing is ticked in advance.
Until you answer, no advertising cookie is placed, no click identifier is kept and no data is sent to our advertising tools. They are not even loaded.
If you decline, nothing changes for you: the site works identically, traffic measurement continues as it does for everyone unless you declined it above, and your request reaches us in exactly the same way. Your choice is remembered for six months, and you can change it at any time through the "Manage cookies" link in the site footer. If you switch from Accept to Decline, the cookies already placed are deleted.
Consent to the form
By submitting the form, you consent to our using your information for the purposes described above. You may withdraw your consent at any time by contacting us.
Sharing and hosting
We do not sell or trade your personal information. It may be processed by the providers that host our website and our email, solely to operate the service and under confidentiality.
The browsing data described above is processed by Google Analytics, a Google service, on our behalf. Your IP address and the address of the page you are viewing are transmitted to it for the purposes of that measurement.
Where you have accepted advertising cookies, the details of your request, namely your name, email address and phone number, are sent together with the click identifier to AdPilot, the advertising measurement tool of our agency BrandNous. AdPilot then passes them to Google Ads and Meta, which use them to match your request to the right ad. This information is used for nothing else, and nothing is sent if you declined.
Information processed outside Québec
Google and Meta are established outside Québec, and the information sent to them for measurement may be processed in the United States. This disclosure is limited to what the measurement requires.
Retention
Your information is kept for as long as is necessary to handle your request and follow up on our business relationship, after which it is securely destroyed.
Traffic measurement data is kept for a maximum of 14 months.
Advertising measurement data is kept for a maximum of 24 months.
The cookie that records your choice expires after six months, after which the banner asks you again.
Your rights
You have the right to access your personal information, to have it corrected and to withdraw your consent. To exercise these rights, contact us. If you believe your rights have not been respected, you may file a complaint with the Commission d'accès à l'information du Québec (CAI).
Privacy officer
For any question about this policy or about your personal information, write to L'Établi's privacy officer at info@letabliarchitecture.com.
Changes
This policy may be amended to reflect legal or operational changes. The update date above indicates the version in force.
