About Us

Through a series of beautifully finished and on-budget projects, Keystone Ridge Developments has become a respected and trusted member of the Toronto construction community.

Each of the layers of detail in a renovation have to be done expertly to have a finished, quality project. From what you don’t see behind the walls: electrical, plumbing, HVAC and structural modifications, to the finishes you do see: creative lighting solutions, decorative millwork & cabinetry, quality appliances & bathroom fixtures, and wall colours that enhance the spaces and premium paints expertly applied ~ all come together in a Keystone Ridge Developments renovation.

This is my company and I oversee all the aspects of each project. I collaborate with clients, interior designers, decorators and architects. The licensed trades who perform specialized work share my dedication to quality and understand that on-time delivery is a key part of client satisfaction.
Take a look at the pictures of some Keystone Ridge projects and see how memorably beautiful homes and condos were brought to life, transformed from forgettable spaces.

My company, my word, your home.

About Samuel Lapidus


We recently purchased our house after Keystone Ridge Developments completed a renovation of the home. The before and after was amazing, thanks to the studious eye of Sam Lapidus. We are very happy with our new home. Sam also included a warranty on the home and is very accommodating on any questions or concerns we’ve had. It’s great to know that Keystone Ridge Developments stands by its work, cares about their customers, and provides ongoing support on whatever may be needed. All in all, a job well done. We would recommend Keystone to anyone looking for a complete home renovation.

Sarah & Jason

My wife and I consider ourselves very lucky to have found a house to purchase that was in the process of being renovated by Sam Lapidus and Keystone Ridge Developments. Sam made the entire process easy and fluid for us. He is a very smart and creative builder. What attracted us initially to this home, was Sam's vision of not just a renovation, but a "restoration" of pieces of a 100 year old home. He is trustworthy and he was an excellent communicator throughout the entire process. We highly recommend Keystone Ridge Developments.


I enjoyed working with Sam on my condo renovation. He is an extremely organized professional with a creative flair and an eye for detail. I highly recommend using Keystone Ridge Developments.


I have worked with Samuel from Keystone Ridge Developments Ltd. for multiple years, and I have always found his designs to be unique and tasteful. We have staged many of his properties and are always in awe of his beautiful work. He creates an atmosphere you can't wait to call home. Samuel has an eye for detail and wonderful custom designs that create an amazing result. Keystone Ridge Developments Ltd. is the ideal company to work with.

Delaine Fox of Next Step Staging

We have been working with Keystone Ridge Developments for several years now and have enjoyed the working relationship immensely… We have seen over the years that Keystone Ridge pays great attention to details when renovating and adding additions to homes. This focus has translated into the creation of high quality renovations…

Sustainability Practices:

Keystone Ridge brings sustainable building practices to every project, offering clients construction options for long term energy and water savings. As a member of the Building Industry and Land Development Association – BILD – where developers and construction firms share best practices and emerging trends in housing and construction.

We understand that construction debris accounts for 40% of the waste in our landfills. We sort all materials before disposal and work to divert materials to recycling centres, Habitat for Humanity’s ReStore and even to local craftsmen, furniture makers and artists.

Considering a home renovation or custom build? We would be pleased to tell you more about why our Green Building Programs makes financial and environmental sense.

Charitable Initiatives

We believe that everyone should have a place to call home. From our renovation projects, we donate salvaged appliances, old kitchens and baths and excess and re-usable building materials to the Toronto Habitat for Humanity ReStore locations.

As an active member of BILD, Keystone Ridge is able to help Habitat for Humanity through the efforts of the association.
