Understand costs, design constraints, and structural considerations before committing to a renovation.
Before committing to drawings or construction, it’s important to understand whether a renovation is structurally practical and aligned with your budget.
Many renovation problems begin when projects move forward without properly testing the design and cost assumptions first.
A feasibility review helps clarify:
• whether the renovation is structurally practical
• realistic construction costs
• potential site or building constraints
• whether the design aligns with your budget
Early clarity helps avoid expensive redesigns and budget surprises later.
Renovation costs vary depending on structural work, site conditions and finish selections.
General planning ranges:
Bathroom Renovations
$25,000 – $45,000+
Structural Wall Removal
$8,000 – $25,000+
Extensions
$3,000 – $4,500 per m²
Thermal / Envelope Upgrades
Highly project specific.
These are planning ranges only. Accurate budgets require clear scope and documentation.
Renovations often reveal hidden conditions such as:
• structural deficiencies
• outdated wiring
• moisture damage
• previous renovation work
Early builder input can help identify these risks and align design, budget and construction approach.
For homeowners planning a renovation, we offer a Pre-Design Feasibility Review before construction begins.
This review typically includes:
• discussion of renovation objectives
• assessment of the existing structure
• preliminary cost guidance
• identification of major constraints
• advice on design direction
The goal is simple: clarity before committing to design and construction.
