Designing for the whole lot, not just the building
It is tempting to think of a project as the building alone — the walls, roofs, and rooms that will eventually be occupied. But a building never stands on its own. It sits on a lot with slopes, soils, easements, sun angles, neighbours, and water that must go somewhere. The site plan is where all of those forces are reconciled, and a thoughtful one makes the difference between a home that ages gracefully and one that fights its own land for decades.
At Cadeonn, we treat the site plan as the first construction document, not an afterthought. Before we refine a floor plan we ask how the building meets grade, where the water flows, and how a person walks from the street to the front door. Those decisions shape everything downstream, and they are far cheaper to get right on paper than in the field.
Grading, drainage, and stormwater
Grading is the quiet hero of any site plan. By shaping the ground with carefully drawn contours and spot elevations, we control where rainfall travels — away from foundations, around walkways, and toward features designed to slow and absorb it. Poor grading shows up as wet basements, eroded slopes, and cracked slabs; good grading is invisible because everything simply works.
Stormwater deserves particular care. Impervious roofs and driveways concentrate runoff, and unmanaged flow degrades downstream waterways. The U.S. Environmental Protection Agency's guidance on nonpoint source pollution and stormwater is a useful primer on why on-site detention, rain gardens, and permeable surfaces matter. We coordinate these features early so they read as part of the design rather than a bolt-on.
A building is only as good as the ground it stands on — the site plan is where architecture and the land finally agree.
Setbacks, easements, and circulation
Every lot carries legal lines that constrain where a building can go. Front, side, and rear setbacks, utility easements, and right-of-way limits define the buildable envelope, and accurate documentation of them keeps a project clear of costly variance requests. The Whole Building Design Guide offers excellent background on integrating these site constraints with whole-building performance.
Circulation is the human layer of the plan. Driveways, parking, walkways, and accessible routes must connect comfortably and meet code. We draw these paths to real turning radii and slopes, not approximations, so the contractor builds what the design promised. This rigor mirrors the drafting discipline behind our as-built drafting work.
Coordinating landscape and the trades
- Establish finished grades early so landscape, structure, and drainage share one datum.
- Locate utilities and easements before fixing the building footprint.
- Design stormwater features as landscape amenities, not leftovers.
- Detail hardscape transitions — steps, ramps, and edges — to real tolerances.
- Coordinate the civil, architectural, and landscape sheets so they tell one story.
Bringing landscape into the conversation early means trees, planting beds, and outdoor rooms reinforce the architecture rather than compete with it. You can see how site work fits the larger documentation picture in our overview of drafting services, and how it connects to the building itself in the modern approach to residential drafting.
Frequently asked questions
What does a site plan include?
A site plan documents how a building sits on its lot: property lines and setbacks, finished and existing grades, drainage and stormwater paths, driveways and walkways, utility connections, parking, and landscape — all coordinated so the design works with the land.
Why is grading and drainage so important on a site plan?
Grading and drainage control where water goes. Proper slopes carry runoff away from foundations and toward managed stormwater features, preventing erosion, flooding, and structural damage while satisfying local codes and environmental requirements.
