A Mount Martha Home Builder Focused on Your Brief
Choosing the right home builder in Mount Martha starts with finding someone who understands your priorities and gives your project proper attention. KM Custom Homes is based nearby in Mount Eliza and brings more than 30 years of building experience to custom homes across the Mornington Peninsula.
We are not a volume builder. Your home starts with your block, budget, lifestyle and plans for the future. Karl works directly with you to shape the brief, review practical options and keep decisions clear as the project moves from early planning into construction.
By taking on a select number of projects, we can stay close to the details, communicate clearly and maintain a consistent standard throughout the build.

New Homes Designed for Mount Martha Living
A strong custom home design responds to the site before it focuses on finishes. Blocks can differ in orientation, slope, access, outlook and exposure. These factors influence the layout, construction approach, window placement and how the home connects with outdoor areas.
We also consider how the house needs to work each day. That includes storage, movement between rooms, private and shared spaces, natural light and future flexibility.
- Site and Block PlanningReview access, orientation, levels and the practical requirements that can affect design and construction.
- Functional FloorplansPlan room sizes, circulation, storage and living zones around the way your household uses the home.
- Materials and FinishesSelect products that support the design, expected maintenance, budget and long-term performance.
- Direct Builder CommunicationSpeak with Karl throughout the project so questions and decisions reach the person managing the build.
Improve the home you already have
Home Renovations and Extensions in Mount Martha
If your location suits you but your home no longer does, a renovation or extension can add the space and function you need. We work on major upgrades that improve how the property looks, feels and performs as one complete home.
Projects may include kitchen and bathroom renovations, additional living areas, extra bedrooms, reworked floorplans and improved access to decks, verandahs or gardens. The aim is to make the new work feel connected to the existing structure rather than added as an afterthought.
Early planning helps identify structural requirements, access limits, approvals and the parts of the existing home worth retaining.
