Custom Home Builders · Richmond Hill
Goldstein Construction is a custom home builder in Richmond Hill. We commission architect-designed residences on infill lots, tear-downs and estate properties across Bayview Hill, Oak Ridges, South Richvale and Mill Pond — under one contract, one schedule and one accountable team.
Where The Project Actually Begins
Most of what gets called custom in Richmond Hill is something narrower — a production home with a longer options list. A genuine custom home is commissioned the way a piece of architecture is commissioned: it starts from the lot, the family that will live in it, and a team assembled around the brief rather than around a catalogue.
Goldstein Construction has been doing that work in the Town of Richmond Hill and surrounding Greater Toronto Area for years. The pages of our process below are written so a homeowner can read them and judge whether a builder — any builder, not only us — is treating the commission seriously. Not every project belongs as a new build: if the existing home is salvageable, a whole-home renovation, a second-storey addition or a room-by-room approach — starting with the kitchen and primary bathroom — often delivers more for the money than a tear-down.
Six Pillars
Six pillars that hold every Goldstein custom home together. Most homeowners only see the last one — the first five decide whether the last one ages.
Pillar 01Lot evaluation, grade, drainage, mature trees, easements and zoning checked before a single drawing is started. Whether you bring the lot or we help you find it, the project is shaped by what the land actually allows.
Pillar 02Architectural drawings coordinated with structural, mechanical, electrical and civil engineers so the home is buildable, financeable and code-compliant before construction is ever priced.
Pillar 03Engineered floor systems, structural steel where it earns its place, continuous exterior insulation, vapour control and rainscreen detailing — the assemblies you cannot see after drywall closes.
Pillar 04HRV-balanced fresh air, hydronic in-floor heating where it matters, dedicated circuits for every appliance category and plumbing manifolds laid out before any wall is closed in.
Pillar 05Insulation, vapour and air barriers, drywall, taping, primer and the first hardwood and tile installations — the moment the home stops looking like a frame and starts reading as architecture. This is where assemblies are closed in, so the sequencing, inspections and trade hand-offs are managed daily, not weekly.
Pillar 06Custom kitchens, principal-room panelling, integrated storage, libraries, wine rooms and dressing rooms — designed alongside the architecture so the joinery and the building read as one.
Pillar 07Lighting control, multi-zone audio, low-voltage backbone, security and network coordinated at the rough-in stage. Easy to live with; impossible to add cleanly after the home is finished.

The First Room
The Commission Journey
A custom home in Richmond Hill is built far more by the decisions made in the first four stages than by the work done in the last four. We resist starting site work before the project is actually ready for it.
We meet on the lot or in our office, walk through how you actually want to live, and understand the budget envelope honestly — no specifications are discussed before this conversation is finished.
Title review, zoning report, grading survey, arborist assessment where required, and a preliminary check against Richmond Hill's by-law 111-22 to confirm what the lot will actually permit.
Three to five massing studies tested against your brief, the lot's sightlines and your neighbours' rooflines. The point is not to choose finishes yet — it is to choose the building.
Architectural, structural and mechanical drawings developed together. By the end of this stage every wall has a reason, every beam has a number and every system has a route.
Building-permit filing with the Town of Richmond Hill, Committee of Adjustment if required, long-lead orders released for windows, structural steel and imported stone so site readiness controls the start date.
Existing-structure demolition where required, shoring of neighbouring grades, excavation, footings and a fully waterproofed foundation engineered for our local clay-rich soils.
Framing, structural steel, roof, windows, building-envelope assemblies, all mechanical rough-ins, drywall, interior trims and finishes — sequenced under one project lead.
HVAC balancing, lighting scenes programmed, deficiencies closed, occupancy inspection and a documented handover that includes drawings, warranties and a maintenance schedule for the first twelve months.
Where We Build
Lot patterns, zoning history and approval workflows differ block by block in Richmond Hill. A builder who already knows the neighbourhood saves the homeowner months of avoidable delay.
Richmond Hill
Large legacy lots and curved cul-de-sacs. We build tear-down replacements that respect the existing neighbourhood scale while modernising envelope and mechanicals.
Richmond Hill
Lots inside the Oak Ridges Moraine require additional environmental review. We coordinate TRCA approvals where the lot triggers them.
Richmond Hill
Deep, narrow estate lots and significant Committee of Adjustment activity. Most builds here go through a Minor Variance for height or coverage.
Richmond Hill
Lots within the Mill Pond Heritage Conservation District trigger a Heritage Permit. We work with the Town's heritage planner from the concept stage.
Richmond Hill
Newer subdivisions where infill replacement is less common but ravine-edge custom builds with engineered slope-stability are an active category.
Richmond Hill
Mixed lot sizes, mature canopies, and the most common Minor Variance combination of GFA, side-yard setback and driveway width.
Worth Naming Plainly
Both have a place in the market — the problem is paying for the second while being told you are getting the first. Seven dimensions where the difference is real.
| Dimension | A Custom Home Builder | A Production Builder |
|---|---|---|
| Starting point | Your lot, your brief, your sightlines | A fixed plan adapted to a generic lot |
| Architecture | Drawn by an architect engaged for the commission | Stock plans modified by an in-house drafter |
| Structure | Engineered for the actual span and load conditions | Pre-engineered to a template that fits 'most' lots |
| Mechanical strategy | Sized and zoned for the specific layout | Default equipment matched to a generic Manual J |
| Selections | Open specification with allowances against real suppliers | Controlled menu — upgrades priced item-by-item |
| Change orders | Anticipated and priced transparently against the budget | Common margin lever; often the source of the final-price gap |
| Project lead | A named project lead from discovery to keys | Sales, design coordinator, site supervisor, warranty desk |
House Standards
Above-grade wall assemblies with continuous exterior insulation and a vapour-permeable air barrier.
Main-floor ceiling height range we design to — measured to the finished surface, not to the joist.
Balanced energy-recovery ventilation on every custom home we build, not just where code currently requires it.
Lighting circuits typical on a 4,500 sq ft custom home, separated by zone and scene rather than by room.

What To Ask Any Builder
The single most useful pre-contract exercise in custom home building. Ask any builder which column they actually operate in — and ask them to show you the document that proves it.
The Shortcut
The Standard
Commission
The most useful conversations we have with future clients in Richmond Hill happen before they own the land, before the architect is hired, before the budget is finalised — when there is still time for the answer to shape the project.
Before You Sign
The questions we are asked in person, answered the way we answer them in person — without the hedging that makes most builder FAQs useless.
A custom home builder leads the entire commission — from sourcing or evaluating the lot, through architectural coordination, municipal approvals at the Town of Richmond Hill, structural and mechanical engineering, trade procurement, on-site construction, finishing and the final occupancy walk-through. Goldstein Construction operates as the single point of accountability across all of those phases, so the homeowner has one contract, one schedule and one budget instead of a stack of disconnected contractors.
Realistic timelines for a true custom home in Richmond Hill run between fourteen and twenty-two months from the day you commission the project. Roughly four to seven months go to design, drawings, soil reports and Committee of Adjustment / building-permit approvals; ten to fifteen months go to demolition, excavation, structure, envelope, mechanicals, finishes and final occupancy. Infill tear-downs in Oak Ridges Moraine areas and lots with septic, mature-tree or conservation overlays sit at the longer end of that range.
A defensible 2026 number for a properly built custom home in Richmond Hill is between $475 and $750 per square foot of above-grade area, exclusive of land, HST, soft costs and landscaping. The lower end reflects a clean rectangular footprint with curated standard specifications; the upper end reflects complex rooflines, structural steel, imported stone, integrated millwork throughout and Tier-1 mechanical systems. Anything advertised meaningfully below that range is either omitting line items or shifting them into change orders.
Frequently, yes. Most legacy lots in Richmond Hill — particularly in South Richvale, Mill Pond and parts of Bayview Hill — were registered under zoning by-laws that no longer match the proportions homeowners want to build today. Anything that exceeds the permitted gross floor area, lot coverage, height, setbacks or driveway width triggers a Minor Variance application to the Committee of Adjustment. Goldstein Construction runs that process in parallel with design development so the schedule does not stall while we wait for a hearing date.
Yes — and it is often the right structure. We frequently come into a project after the homeowner has already established a relationship with an architect or interior designer they trust. In that case we operate as the construction manager, joining the consultant team during design development so that constructability, cost and schedule are reviewed before the drawings are finalised. The alternative — pricing a finished drawing set cold — is the single most common reason custom-home budgets blow up in the first month.
A production builder starts from a fixed plan and lets you select finishes from a controlled menu. A true custom home in Richmond Hill starts from your lot, your brief and your sightlines — the floor plan, structure, envelope assemblies, mechanical strategy, ceiling heights, window sizes and millwork are all designed for that specific commission. Practically, that shows up in the things that cannot be retrofitted: where the structural steel lands, how the HVAC is zoned, where the natural light falls at 4pm in November, and whether the second-storey hallway is wide enough that two people pass without turning sideways.
Yes. Our custom-home work covers the surrounding Greater Toronto Area — Vaughan, Markham, Aurora, Thornhill, King City, North York and Toronto proper. We keep our Richmond Hill base because the municipal approval workflow, soil conditions and lot patterns here are well understood by our team; that institutional knowledge translates directly into faster permitting and fewer surprises on neighbouring municipalities.
