Custom Home Builders in Greely
Build the home you want on the acreage you love, with one team handling the well, septic, design and build.
Custom Home Builders in Greely, on Your Terms
Families come to Greely for room: a rural lot, mature trees, space for a workshop and a driveway long enough to forget the neighbours. As custom home builders in Greely, OGC designs and builds one home at a time for the lot you own or are about to buy, so the house is planned around the land rather than squeezed onto it.
Most of Greely runs on private wells and septic systems, and the City operates a communal well system for Shadow Ridge. That means servicing is part of the design from the first visit, not a line item at the end. When you build a custom home in Greely, the septic bed, the well, the driveway and the house are sited together.
We also plan the deck, porch and outdoor living space into the build, so they are permitted and built with the house instead of added later. If you would rather improve the home you already have, see our home renovations in Ottawa, and for a wider view of rural parcels read about large lots in Ottawa.
- A lot walk and servicing check before any design work
- Septic and well planned with the house, not after it
- Decks, porches and outdoor living designed into the build
- One team for design, permits and construction

Greely Home Builders, From Lot to Keys
A Greely build runs on two approval tracks at once, the house and its septic system. Here is how we take a new custom home from bare acreage to move-in day.
We walk the property with you and confirm what it can carry: the zoning, the lot size and frontage, where a septic bed and a well can go at the required separation, and whether any part of the land falls under a conservation authority regulation. On a Greely lot that last point is checked lot by lot.
- Zoning, lot size and frontage review
- Well and septic siting
- Conservation authority screening
- Driveway, access and grading
Your designer works through the plan with you room by room and in 3D, placing windows for the views and the sun on your lot. Read more about our home design process.
- Floor plans and elevations
- 3D walkthroughs
- Outdoor living planned with the house
- Finish selections by tier
The building permit comes from City of Ottawa Building Code Services. The septic system is approved separately, through the Rideau Valley Conservation Authority on the City's behalf, which gives a 5 to 10 business day turnaround once an application is complete.
- Structural engineering
- Septic design and RVCA approval
- Building permit drawings
- Geotechnical work where soils or slopes call for it
Before anything is ordered, you approve a fixed price for the scope, with a schedule and milestone dates you can share with your lender.
- Itemized fixed-price scope
- Build schedule with milestones
- Selections locked before ordering
- Tarion enrolment
One project manager runs the site from excavation to finishes. Value builds typically take 8 to 12 months of construction, premium homes 12 to 18 and luxury homes 18 to 24. More on how long it takes to build a house in Ottawa.

What a Custom Home Costs in Greely
Ottawa-wide construction ranges by tier. On a Greely acreage, the site and its servicing are the part that varies most from one lot to the next.
Design and Size
Square footage sets the base, but complexity moves the number more. Multiple wings, vaulted ceilings, a cantilevered second storey or a lot of structural steel cost more per square foot than a simple footprint of the same size.
Finishes
Siding, flooring, tile, windows, millwork and appliances move a home from one tier to the next. Fibre cement instead of vinyl, hardwood instead of laminate, and triple-pane windows are typical examples.
Site and Servicing in Greely
A rural lot carries costs a serviced lot does not: a new well by a licensed well contractor, a septic system sized for the house, a longer driveway and site grading. The 2026 RVCA fee for a new Class 4 or 5 residential septic system is $990. We price the rest from the site visit.
These ranges cover construction only, before land, design, permits and landscaping. Ontario's enhanced HST rebate on new homes can be worth up to $130,000 where construction starts between April 1, 2026 and March 31, 2027, and City of Ottawa development charges for a new home were cut in July 2026.

Greely Custom Home Questions
Construction runs about $315 to $330 per square foot for a value build, $420 to $450 for premium and $500 to $1,100 or more for luxury, so a 2,500 sq ft home starts around $787,500 and can pass $2.75 million. A Greely lot adds the well, the septic system and the driveway, which we price from the site visit. See the custom home cost guide.
Plan on 8 to 12 months of construction for a value build, 12 to 18 months for premium and 18 to 24 months for luxury, with design and permits before that. On a rural lot, the septic approval runs alongside the building permit. More on how long it takes to build a house in Ottawa.
Yes. Before you buy, we check what the lot can carry: its zoning, its size and frontage (rural RR and RU zones generally call for 0.8 hectares and 50 metres for a detached home, with some RR subzones lower), room for a septic bed and a well at the required separation, and whether any part falls under a conservation authority regulation.
Most custom homes are financed with a construction mortgage, also called a progress-draw mortgage, which releases money in stages as the build reaches milestones instead of as one lump sum. Many Greely buyers purchase the lot first, using a land loan or a combined land and build mortgage. Our guide on how to finance a custom home build in Ottawa walks through the options.
It is designed to be. Insulation, windows, airtightness and the heating system are settled at the design stage, when upgrades cost the least to add, and we show you what options such as triple-pane windows add to the budget before you choose.
The septic system is approved by the Rideau Valley Conservation Authority, which reviews septic systems anywhere in Ottawa on the City's behalf. The application goes through My Service Ottawa, starting work before the permit adds a 50% surcharge, and the permit is valid for 12 months. A new well is built by a licensed well contractor, who files a well record within 30 days and tags the well.
Only if the work falls in a regulated area. Under Ontario Regulation 41/24, development in a floodplain, on unstable slopes or soils, in a wetland or within 30 metres of one needs a conservation authority permit, separate from the building permit. Which authority, if any, regulates a given Greely lot is a per-lot check, so we confirm it before design.
