Southern Highlands' Trusted Name in Renovations
Experience Proven Through Every Detail
A renovation should feel like one cohesive vision, not a series of disconnected updates. With more than 30 years of experience building and renovating across the Southern Highlands, we understand how these homes need to work: the way northern light moves through a living space, how a home should sit against its land, and how period character can be honoured while a property is brought up to the standard our clients expect.
Our Approach
Our Approach
Renovating Across the Southern Highlands
We honour the character already present in a home while translating our clients' vision into a considered, enduring result. Every renovation is led personally by Kim Middleton and delivered by a team that has spent three decades building trust across the region, through repeat clients, referrals and recognised work.
Our approach draws on established relationships with trusted trade and design partners, including A&R Engineering and Design, Tziallas Omeara Architecture Studio, Studio G Design, Bloor Plans, Evalock Windows & Doors, Hanlon Windows, Harvey Norman Commercial and Traditional Timber Frames. This network allows us to manage a whole-home renovation with the same precision and craft as a custom build.
We take on renovation projects throughout Bowral, Mittagong, Berrima, Moss Vale, Burradoo, Exeter and Sutton Forest, drawing on our familiarity with the terrain, climate and character specific to each of these communities. From the established streets of Bowral to the rural properties around Sutton Forest and Exeter, we understand how local conditions, from heritage overlays to exposed rural sites, shape a successful renovation.

Frequently Asked Questions
FAQs about Renovations in the Southern Highlands
How much does a whole-home renovation cost in the Southern Highlands?
Cost depends on the scope of structural work, the age and condition of the existing home, and the level of finish specified.
What is the difference between a home renovation and a new custom home?
A home renovation works with an existing structure, retaining and improving what is already there, while a custom home is built from the ground up. Southern Highlands character homes and country properties are well suited to renovation, where existing charm can be preserved while the layout and function are brought up to a modern standard.
How long does a whole-home renovation take?
Timelines vary with the scope of structural work, council requirements and the age of the property.
Do you renovate character or heritage homes in the Southern Highlands?
Yes. Many of our renovation projects involve character homes across Bowral, Berrima and Moss Vale, where the goal is to honour the home's existing detail while improving how it functions for modern family life.
Is KMI Builders a licensed builder in the Southern Highlands?
Yes. KMI Builders is a Master Builders Association of NSW member, family-run and based in Bowral, with more than 30 years of experience delivering renovations and custom homes across the region.
