Custom Home Builder in Nepean
Replace an older house with a new one designed for your family, on the lot and street you already know, with one team from plans to keys.
A Custom Home Builder in Nepean, on Your Terms
Nepean is where many Ottawa families already have the location they want, just not the house. As a custom home builder in Nepean, OGC designs and builds teardown rebuilds and homes on infill lots, so you keep the street, the schools and the commute and get a house that fits.
Inner Nepean sits inside the Greenbelt and the newer parts sit outside it, and that changes a few things, development charges among them. What stays the same is the work: zoning first, then the existing house, the trees and the neighbours, then a design that fits the lot. Read about infill home construction and what counts as an infill lot in Ottawa.

Nepean Home Builders, From Lot to Keys
Most Nepean custom homes are rebuilds. Here is how we take one from the old house to the new one.
We check what the zoning allows under both of Ottawa's by-laws, look at the existing house, the trees and the neighbours, and flag early whether a minor variance would be needed. The 2026 Committee of Adjustment fee for an urban minor variance is $3,759.

- Committee of Adjustment check
- Tree survey
- Demolition planning
Your designer fits the house to your lot and your street, and you walk it in 3D before engineering. See our home design process.
- Floor plans and elevations
- 3D walkthroughs
- Massing for the street
- Finish selections by tier
We prepare the City of Ottawa permit set, including a grading plan for a footprint over 55 square metres and an engineer's excavation and shoring plan where the foundation is within 3 metres of a lot line. A protected tree can add a permit, an arborist report and a tree protection plan.

What a Custom Home Costs in Nepean
Ottawa-wide construction ranges by tier. On a Nepean rebuild, demolition and site work sit on top.
Design and Size
Size sets the base; complexity sets the rate. Cantilevers, tall ceilings, big openings and structural steel push the cost per square foot up.
Finishes
Cladding, windows, floors and cabinetry decide the tier. Hardwood, fibre cement and triple-pane windows are common upgrades.
Site Work in Nepean
Demolition, excavation, shoring near a lot line, the grading plan, services and any tree protection or minor variance are priced from the lot.
These cover construction only. Ontario's enhanced HST rebate is worth up to $130,000 on a new primary residence where construction starts between April 1, 2026 and March 31, 2027, and the City of Ottawa's development charges for a new home, which differ inside and outside the Greenbelt, were cut in July 2026.

Nepean Custom Home Questions
Think in tiers: value homes cost about $315 to $330 per square foot to build, premium homes $420 to $450, and luxury homes $500 to $1,100 or more. At 2,500 sq ft, that spans roughly $787,500 to more than $2.75 million. A rebuild adds demolition and site work. See the custom home cost guide.
The construction stage runs about 8 to 12 months for value homes, 12 to 18 for premium and 18 to 24 for luxury. Zoning review, any minor variance and the permit come first. More on how long it takes to build a house in Ottawa.
Yes. We review zoning, servicing, trees, the existing house and the distance from a new foundation to the lot lines before you buy, and tell you whether a minor variance would likely be needed.
Most buyers use a construction mortgage, which releases money in stages as the build progresses rather than up front. If you are rebuilding on a lot you own, equity in it can cover early design and permit costs. See our guide on how to finance a custom home build in Ottawa.
It is designed to be. We plan insulation, windows, airtightness and heating together, and price upgrades such as triple-pane windows before you choose.
Yes, that is most of our Nepean work. We handle demolition, the grading plan, an engineer's shoring plan where the foundation is within 3 metres of a lot line, and tree protection. Read more about infill home construction.
Two zoning by-laws are in force in Ottawa, By-law 2008-250 and By-law 2026-50, and the more restrictive provision applies where they differ. Plan on up to three units on a serviced lot. See Ottawa's 2026 zoning by-law and custom homes and minimum lot sizes by zone.
