Architect in St. Catharines
You may want more space in a familiar neighbourhood, a new use for an existing property or homes on an underused site. In St. Catharines, those goals need a design that understands what is already around it. OAN Architect helps you develop architectural options and coordinated drawings that connect your ambitions with the property.

New possibilities within an established city
St. Catharines includes very different neighbourhood settings, from downtown streets to Port Dalhousie and established residential areas. We look at the immediate surroundings, the building's existing condition and the property's planning context before developing the design direction.
Infill that respects everyday neighbours
Adding a home or a larger building on an established street means thinking about more than the parcel boundary. The position of living rooms, upper windows and outdoor spaces affects how neighbours share light and privacy. We explore the building's size and placement alongside the layout, so the design responds to its surroundings.
Heritage needs an early conversation
For designated properties and properties within a heritage conservation district, St. Catharines may require a heritage permit for changes. Before an addition or exterior redesign takes shape, check the property's status and the relevant guidance. Understanding the features that matter helps establish where new work can sit and how it relates to the existing building.
A useful life for existing space
A storefront or older building can offer a strong starting point, but the visible floor area does not tell the whole story. Existing exits, changes in level, structure and servicing influence how a new use will fit. We bring those questions into the architectural brief before a commercial layout becomes too fixed.
02Designed around you
What are you planning in St. Catharines?
Home additions and new houses
Make room for family life while keeping the qualities you value in the property. We consider the connection between existing and new rooms, natural light and the outdoor space that remains.
Infill and multi-unit housing
Explore how housing can fit an established site with workable entrances, circulation and private space. Unit arrangements and building form are developed together, with the street and adjoining properties in view.
Retail and workplace design
Plan a space around the customer journey and the tasks your team performs. Existing St. Catharines buildings need careful measurement and a clear proposed use before detailed architectural drawings begin.

Questions about building in St. Catharines
How do I find the planning information for my St. Catharines address?
The City's CIVIC Maps system includes property, zoning and Official Plan layers. It is a useful first look at a site. Bring the address and any existing records to our discussion, then confirm the applicable requirements with the City before relying on a design assumption.
Can a contemporary addition work beside an older home?
It can be worth exploring. The key questions include the addition's scale, its visibility from the street and its relationship to the original roof, windows and materials. Where heritage controls apply, the design also needs to respond to the property's identified attributes and the City's review requirements.
Useful local resources
These official pages can help you prepare for a conversation. The requirements for your address and proposed work should be confirmed before the design is finalized.
