Home Extensions and Renovations Narre Warren

For Narre Warren homeowners ready to invest in a serious extension or renovation, the builder you choose matters as much as the design. RAW Building Group provides director-led building for projects that go beyond surface-level updates, delivering the structural changes, quality finishes, and coordinated trades that transformational builds require.

✓ Direct contact with a Director throughout your entire project

✓ Projects chosen for quality and complexity, not turnover

✓ A single team responsible for design, approvals, construction, and handover

Extensions and Renovations That Suit Narre Warren Homes

Narre Warren has grown quickly, and many of the homes built during that growth were designed to a standard template. As families settle in and needs change, those layouts often fall short. We work with architects and engineers to deliver builds that rethink floorplans, add meaningful space, and create homes that feel purpose-built for the people living in them.

Second-storey additions that make the most of your existing block by adding bedrooms, living areas, or dedicated work-from-home spaces above the current footprint

Open-plan transformations that knock out walls between kitchen, meals, and living to create a single connected space designed around how your family actually uses the home

Whole-home renovations that address layout, flow, storage, and finishes across the entire property rather than updating one room at a time

Custom new builds for homeowners who want an architect-designed home built with genuine craftsmanship on a new or existing Narre Warren site

Kitchen and bathroom renovations as part of larger builds, featuring bespoke joinery, premium materials, and trades managed under one coordinated program

The Builder You Actually Speak To Is the One Running Your Build

One of the most common frustrations with larger builders is the gap between who you meet during the sales process and who actually manages the work. At RAW Building Group, there is no gap. A Director is the person you consult with at the beginning, and the same Director leads the build through to completion. Every decision, every trade call, every update comes from someone who knows your project inside and out.

It starts with a free consultation at your Narre Warren property where we assess the site, discuss your priorities, and walk you through what’s realistically achievable. We then collaborate with your architect on design and documentation, coordinate permits and engineering, and manage the full build with consistent director oversight until handover.

Frequently Asked Questions


  • We take on substantial extensions, whole-home renovations, and custom new builds that involve architect collaboration, structural work, and coordination across multiple trades. Kitchen and bathroom renovations are delivered as part of these broader projects.

  • The person you speak with is the person managing your build. We don’t hand projects off to site supervisors or rotate through project managers. A Director leads from consultation to handover, and we limit the number of builds we take on to make sure that’s genuinely possible.

  • Extensions and renovations typically run 8 to 16 months. Custom new builds may take longer depending on size and complexity. We set out a clear timeline during consultation so you know what to expect from the start.

  • A Director meets you at your property to walk the site, talk through what you want to achieve, and give you an honest assessment of what’s realistic. There’s no cost and no obligation to proceed.
