Feasibility Guide

Understand costs, design constraints, and structural considerations before committing to a renovation. 

Is Your Renovation Feasible?

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.

What Does a Renovation Cost on the Bass Coast?

Renovation and extension costs vary depending on structural complexity, site conditions, and level of finish.

As a general planning guide:

Bathroom Renovations
$25,000 – $45,000+

Structural Wall Removal
$8,000 – $25,000+

Extensions
$3,000 – $4,500 per m² for fully serviced living spaces (kitchens, bathrooms, laundries).

Straight forward extensions — such as basic rooms or non-serviced additions — can be lower, typically from around $2,000 per m² depending on scope, access, and finishes.

Thermal Performance Upgrades
Highly project specific.

These figures are intended for early planning only.
Accurate budgets require clear documentation, engineering, and defined scope.

Why Early Builder Input Matters

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  • outdated wiring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.

Project Feasibility Review

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.

This service's cost varies based on project complexity however Feasibility reviews start at $400.
