ABOUT JMAR BUILDING CO
BUILT FOR LIVING
DESIGNED FOR LIFE
Building a forever home is one of the biggest decisions you’ll make. You deserve a team that takes that seriously – one that’s across every detail, holds every trade to a high standard, and keeps you informed every step of the way.
JMAR Building Co. is a Hawkesbury-based builder working with homeowners across the Hawkesbury, Hills district, Penrith and the Lower Blue Mountains. Every project is led with the same attention to detail and commitment to quality because that’s the standard we hold ourselves to, regardless of the size of the job.
WHAT WE BUILD
CUSTOM HOME BUILDING SERVICES ACROSS THE HAWKESBURY & SURROUNDS
From custom new homes to knockdown rebuilds and significant renovations — we work with homeowners who want the job done properly, by a team that’s personally accountable for every stage of the build.

CUSTOM BUILT HOMES
Designed around your block, your family, and the life you want to live in it. Whether it’s acreage in the Hawkesbury, a hillside in the lower Blue Mountains, or a lot in the Hills – your home starts with your brief, not our catalogue.

RENOVATIONS & EXTENSIONS
For homeowners in the Hills, Hawkesbury, and surrounds who love where they live but know the house needs more – more space, better flow and rooms that actually work for the life they’re living now.

KNOCKDOWN REBUILD
You don’t have to leave the street you love to get the home you want. At JMAR Building Co, we manage the entire process from demolition right through to handover. You can start completely fresh without leaving the place you call home.

SECOND STOREY ADDITIONS
More space, without the upheaval of moving, this is perfect for families who love where they live and want to grow into it. A second storey addition gives you the extra space, built properly into the existing structure so the whole house feels like it was always meant to be that way.
