Sa formation d’architecte, un atout majeur et exceptionnel pour un designer d’intérieur, ainsi que son souci perpétuel du détail assurent un résultat homogène, esthétique, fonctionnel et une parfaite optimisation des volumes. Comme en témoignent ses nombreuses réalisations de propriétés neuves ou rénovées, ses connaissances aiguisées des différents styles alliées à sa vision structurée de l’espace et son indéniable imagination lui permettent de créer des projets uniques émergeant de sa propre vision et de celle de chaque client.

Pour ce designer qui s’est forgé une solide réputation dans le domaine des résidences de prestige, chaque projet, du plus petit au plus grand, est original et représente un renouvellement perpétuel. Pour lui, offrir un milieu de vie en symbiose avec les personnes qui l’habitent représente la satisfaction première des fruits de son travail. ### Services Provided - Interior Design - Custom Home Design - Interior Archtiecture - Whole Home Remodeling ### Areas Served - Ahuntsic-Cartierville - Anjou - Bordeaux - Brossard - Candiac - Côte-Saint-Luc - Dorval - Golden Square Mile - Greenfield Park - Hampstead - Hemmingford - Jacques-cartier - La Prairie - La Salle - Laprairie - Longueuil - Mont-royal - Montreal - Montréal-Ouest - Mount Royal - Mount-royal - Pointe Claire - Pont-viau - Rosemont-La Petite-Patrie - Saint Laurent - Saint Leonard - St Leonard - Villeray Saint-Michel-Parc-Ext - Westmount ### Typical Job Cost CAD 500,000 - CAD 10,000,000 ## Business Details | Field | Value | | --- | --- | | Business Name | Mario Januario Design | | Address | 3859 St-Urbain, Montreal, Quebec H2W 1T6, Canada | | Phone | (514) 998-9757 | | Website | http://mariojanuario.com | | Followers on Houzz | 128 | ## Contact - **Houzz profile:** [Mario Januario Design](https://www.houzz.com/professionals/interior-designers-and-decorators/mario-januario-design-pfvwus-pf~1384821438) - **Website:** http://mariojanuario.com - **Phone:** (514) 998-9757 ## Credentials - **Best of Houzz:** 6 awards (2018–2026), for Service, Design. ## Reviews **Overall rating: 5.0 out of 5 — 11 reviews** *Aspect averages:* - Work Quality: 5.0 - Communication: 5.0 - Value: 5.0 ### All 11 reviews **★★★★★ — pieknosc, April 2025** > We found Mario Januario Design on internet. > From the very beginning we were totally blown away with Mario's architectural and design skills. > Mario helped to design the lay out of the property , select all the materials, and furnish our home (7 stories, build in 1913) > The result of his work is nothing short from spectacular. > If I could give 6 stars I would. **★★★★★ — Sharokh Fahm, July 2020** > C’est le meilleur, c’est un autre niveau de goût, de professionnalisme, gentillesse, ça fait 30 ans que je suis dans l’ immobilier et la construction, Mario est de loin le meilleur architecte d’intérieur avec qui j’ai travaillé.

My husband and I have different tastes and Mario was able to blend both of our visions and make both of us happy. When we decided to build a new house , Mario was the automatic choice. His attention to detail and his exquisite taste created a home that we still love 7 years later!!! He works extremely well with the construction team and always finds a solution when faced with construction limitations. He is a very artistic individual and is able to work with a classic, contemporary or modern decor. I highly recommend him. **Comment from Mario Januario Design:** > Thank s soo much Elisa!!! soon i will design for your kids! ;-) **★★★★★ — B and J, Nov. 2016** > No previous interior designer with whom we have worked has come close to the talent of Mario. We had the pleasure to work with him from the interior concept and design through execution and implementation of our new home build. He added value at every step. His passion for design, eye for detail and commitment to excellence is immeasurable. **Comment from Mario Januario Design:** > Thank you Barbara! was a pleasure working with both of you! a lovely team. > > MJ **★★★★★ — Paule Bourbonnais Design, Feb. 2016** > Mario Januario est un collègue en design d'intérieurs. Raffiné et amoureux du beau, M. Januario est reconnu pour ces projets d'envergure aux styles uniques. Il répond aux besoins de sa clientèle et pousse toujours plus loin chacun de ceux-ci afin d'en rendre un produit fini de qualité. **Comment from Mario Januario Design:** > Merci Paule! nous avons tous les deux le sens du beau et le souci du détail. > > MJ **★★★★★ — jetsetyyz, Dec. 2015** > Having had some help from Mario Januario many years ago, we decided to call on him to assist in designing some major renovations for the condo we bought in July 2015. It is a pleasure to work with Mario. He has amazing creative skills and was again able to inspire us, while responding positively to any concerns and integrating any ideas we had. He works very well and respectfully with all the other professionals involved in the project, some of whom were reluctant to deal with a designer because of previous negative experiences. Unfortunately the project will not be finished until early in the New Year so photos to illustrate the transformations that he has brought about are missing. **Comment from Mario Januario Design:** > Thank you ! very touched after all those years.... asking me for a new project.. with a lot of challenge! > > Mj ## Selected projects - [Classique Revisité](https://www.houzz.com/hznb/projects/classique-revisite-pj-vj~7587172) - Location: Not specified - Photos: 26 - [Fenêtre sur nature](https://www.houzz.com/hznb/projects/fenetre-sur-nature-pj-vj~7414540) - Location: Not specified - Photos: 18 - [Bleu passion](https://www.houzz.com/hznb/projects/bleu-passion-pj-vj~7414385) - Location: Not specified - Photos: 24 - [Tranquillité et lumière](https://www.houzz.com/hznb/projects/tranquillite-et-lumiere-pj-vj~2650809) - Location: Boucherville, QC - Photos: 15 - [Penthouse sculptural](https://www.houzz.com/hznb/projects/penthouse-sculptural-pj-vj~6805145) - Location: Montréal, Québec - Photos: 16 - [Lueur asymétrique](https://www.houzz.com/hznb/projects/lueur-asymetrique-pj-vj~2650861) - Location: Otterburn Park, QC - Photos: 7 - [Moderne et chic](https://www.houzz.com/hznb/projects/moderne-et-chic-pj-vj~2177575) - Location: Westmount, QC - Photos: 13 - Description: Owners of a large suburban family home chose to relocate to Westmount to get closer to services after the departure of their offspring and moved into a new condo of approximately 1,800 square feet.

"We worked in duet with the architect Eric Tremblay so that the sight is the essential decor". The inspiration of the design comes also from outside, by the integration of organic materials, but also by means of structural effects. For example, the wooden slats placed on the wall and the suspensions of the entrance hall respond to the verticality of the trees. In the same vein, the constant pre… - [Souffle classique](https://www.houzz.com/hznb/projects/souffle-classique-pj-vj~7414562) - Location: Not specified - Photos: 24 - [Écho moderne](https://www.houzz.com/hznb/projects/echo-moderne-pj-vj~7414329) - Location: Not specified - Photos: 20 - [Lac St-Louis](https://www.houzz.com/hznb/projects/lac-st-louis-pj-vj~2104434) - Location: Quebec City, QC - Photos: 17 - Description: Literally snapped up by the lake landscape, this new house built for a couple and three children is dressed in white, ivory and dark wood.
