Renovation Planning and Design Services in Oshawa
Draw the House You Actually Have Before You Plan the One You Want
Oshawa has some of the oldest residential stock in Durham Region, and that is exactly why design-stage work pays here. Century houses through O’Neill and the downtown core, and post-war bungalows across McLaughlin and Donevan, have been altered by decades of owners — knob-and-tube left in a ceiling, a wall removed without a beam, a bathroom added over undersized joists. None of it appears on any drawing until someone measures the building properly.
905 Reno produces that record first, then designs from it, with drawings prepared to the Ontario Building Code and City of Oshawa Building Services requirements so the permit path is clear before construction is priced.
Why Oshawa Homeowners Invest in Design First
In older Oshawa housing, the gap between what a house looks like and how it was actually built is where renovation budgets disappear. Balloon framing, undersized joists, previous unpermitted work and mixed-era wiring all change the scope once they surface. Our designers survey the real conditions — century homes near the downtown core, wartime and GM-era bungalows through Vanier and Lakeview, and newer detached stock out toward Windfields and Samac — and build a plan that accounts for what is behind the plaster.
What an Oshawa homeowner gets from a 905 Reno design package:
Licensed and insured renovation design professionals serving Oshawa homeowners
Specialists in older and heritage-era housing stock across Durham Region
Complete pre-construction service from conditions survey to permit submission
Drawings prepared to the Ontario Building Code and City of Oshawa requirements
Clear design fees with defined deliverables, phasing options and timelines
Material and finish schedules agreed before any demolition begins
We handle the full pre-construction path — measure, concept, structure, permit set — so your Oshawa contractor starts from verified conditions rather than assumptions.
What Planning Is Worth on an Older Oshawa Home
In a century house, almost every unknown is expensive and almost all of them are discoverable at design stage. Finding them there turns a mid-build crisis into a line item.
Protect the Budget on an Old House
Verified as-built drawings and a costed finish schedule stop an older Oshawa house from rewriting its own budget once the walls are open.
Uncover Structural and Wiring Issues on Paper
Undersized framing, past unpermitted alterations and mixed-era wiring are far cheaper to find during a design survey than during demolition.
Coordinate Trades Around Unknown Conditions
A coordinated set tells your general contractor what to expect behind the plaster, so trades are booked around real conditions instead of optimistic ones.
Prepared for City of Oshawa Submission
Every set is prepared to Ontario Building Code and City of Oshawa Building Services standards, so permits are issued without repeat submissions.
Design Directions That Suit Oshawa Homes
A brick century home off Simcoe Street, a post-war bungalow in Donevan and a newer two-storey in Windfields present three completely different sets of constraints, so every project opens with a measure, an as-built drawing set and a frank conversation about budget and phasing.
Where Oshawa projects most often go:
Century-home restoration and main-floor reworking through O'Neill and Central Oshawa
Post-war bungalow additions and dormer conversions in McLaughlin, Vanier and Donevan
Legal secondary-suite design for north Oshawa near Ontario Tech and Durham College
Phased renovation planning that lets budget-conscious projects proceed in stages
Kitchen and open-plan conversions for newer detached homes in Samac and Windfields
Where We Work Across Oshawa
905 Reno plans and designs renovations throughout Oshawa — across O’Neill, McLaughlin, and Central Oshawa, through Donevan, Eastdale, and Vanier, out to Samac, Windfields, Lakeview, and Pinecrest.
Two local realities shape design work here. Properties near the creek systems fall under Central Lake Ontario Conservation Authority regulation, which adds a review step before permits are issued. And demand for legal secondary suites is unusually strong in north Oshawa around Ontario Tech and Durham College — which makes ceiling height, egress and fire separation design questions worth resolving before any money is spent below grade.
Why the Plan Protects the Budget
Oshawa homeowners often find that a structural or electrical issue discovered after demolition costs five to ten times what it would have on paper — and that an incomplete submission can hold a project at City of Oshawa Building Services or the Committee of Adjustment for weeks.
A complete pre-construction set closes that gap and gives every trade a single, coordinated reference.
