Renovations, additions and custom homes
A better kitchen and living area, another bedroom or a stronger connection to the garden may lead to different building options. Grand Design Build can help you compare a major home renovation, an addition and a custom home using the same priorities for space, daily routines and budget.
Start with the house and the land together. The existing structure, changes in level, access beside the house and trees around the proposed work all belong in the first design conversation. A larger floor plan is only useful when its rooms, stairs and outdoor connections work well together.
This guide includes Cliffside within the wider City statistical area of Birchcliffe-Cliffside. The housing figures below describe that full area. They do not describe Cliffside alone or establish what can be built on your lot.

Local housing context / 2021
The City’s Birchcliffe-Cliffside profile records single-detached homes as its largest structural category, at 51.4%. The largest construction-period category covers dwellings originally completed in 1960 or earlier. These are separate measures of the area’s housing.
4,940 of 9,620 occupied private dwellings in the structural-type group.
5,495 of 9,615 occupied private dwellings in the construction-period group.
Bring the current survey, measured plans and records of later alterations. Use them to identify which parts of the existing home the proposed work would retain or change.

Cliffside is discussed here within the wider official Birchcliffe-Cliffside statistical neighbourhood (122). Statistical, community and planning-policy boundaries serve different purposes.
Before the scope is fixed
The City’s Cliffside Avenue Study concerns Kingston Road between the Danforth Avenue intersection and Chine Drive. A home on a nearby residential street needs its own zoning review. Check the address before borrowing a building size or form from the corridor.
Collect the survey, floor plans and records of previous changes. Identify which rooms, foundations and structural elements the proposal would keep, then assess what needs further investigation before pricing the work.
Put the same room list into both options. Review stairs, storage, daylight and the connection to the garden, along with the extra floor area. A rear addition and an upper-storey addition affect the existing home in different ways.
If the property is beside a slope, ravine or natural feature, check the City’s protection map early. Mark trees, retaining walls and proposed excavation on the site plan. Address-specific review determines which protections and approvals apply.
For a laneway or garden suite, establish whether the lot abuts a public lane and review access, trees and the space between buildings. A large-looking rear yard does not by itself confirm that a suite will fit.
Set out what is included, what remains unresolved and who will manage each part of the work. Review design decisions, permit work, site access and living arrangements before construction begins.
For the property and proposal, the City’s preliminary zoning review information explains the available review routes.

What we do

Develop the site plan, house design and application drawings around the existing property and proposed work. Identify the zoning questions before the design is fixed.
Explore architectural design & permits
Plan a major home renovation that brings the layout, structure, building systems and finishes together. Consider how the rooms connect throughout the home.
Explore home renovations
Compare rear, side or second-storey additions with the house you intend to retain, including stairs, structure and the outdoor space left around it.
Explore home additions
Develop a new home from the site and household brief, with the rooms, exterior and construction scope considered as one project.
Explore custom homes
Explore a separate dwelling where the lot, access and applicable requirements support it. Review laneway and garden suite options on their own merits.

Coordinate the agreed construction work, decisions and updates. Keep responsibilities, selections and changes documented through the project.

Work through the property, scope and decisions before construction. Keep responsibilities and changes recorded as the project progresses.
Discuss your project

Start with what works, what does not and the changes that matter most to your household.
Assess the layout, structure and relevant site conditions before developing the renovation approach.
Coordinate the rooms, structural approach, services and finishes. Review inclusions, exclusions and responsibilities before construction.
Coordinate the drawings and applications required within the agreed scope, including a Committee of Adjustment application where needed. Allow for review comments and further information. The proposal identifies how City fees, Committee fees and survey costs are handled.
Sequence the work and trades around the project plan. Keep decisions and changes documented, with updates through the project coordinator.
Walk through the finished work, record outstanding items and agree the follow-up. Confirm the applicable closeout and warranty documents.
Planning questions
Cliffside is a familiar community name. The City’s Birchcliffe-Cliffside profile is a wider statistical area, numbered 122. Use the address lookup to confirm the applicable official profile; the statistics here should not be read as Cliffside-only figures.
Compare each option against the same room needs and site information. Review the existing building, the work retained, the additional space and the decisions that remain. The best starting point is a measured understanding of your property, rather than choosing from exterior photographs alone.
A nearby building can be a useful design reference, but its planning context may differ from yours. The Cliffside corridor study has a defined area. Review the zoning and proposal for your address before using a corridor project as a guide.
Include them in the first site review. The City provides an address-based ravine protection map and information about tree permits. Establish the relevant conditions before deciding where excavation, a new structure or construction access will go.
Send the address, a few existing photographs, the rooms or problems you want to address, and any survey or plans you already have. Tell us whether you are comparing a renovation, an addition, a replacement home or a separate suite.
