OUR SERVICES

NEW HOMES

At JS Build, we guide you through every step of your new home journey. Whether you have a full set of plans or are starting with just a few ideas, we can design a tailored build and quote that suits your needs and budget. Every project, big or small, receives the same level of care, craftsmanship, and attention to detail. We’re here to bring your vision to life.

ADDITIONS, EXTENSIONS & RENOVATIONS

Sometimes, your existing home just needs that perfect addition to truly fit your lifestyle. JS Build specialises in seamless extensions and alterations that blend effortlessly with your home’s original character. We understand that renovations can be overwhelming, which is why we’re committed to making the process as smooth and stress-free as possible, guiding you through every step with clear communication and expert advice.

PROJECT MANAGEMENT

Project management is the backbone of a successful build. Knowing what’s happening, when it’s happening, and who’s responsible is often the difference between a smooth project and a stressful one. At JS Build, we manage every aspect of your build — from initial planning and council approvals to coordinating trades and delivering the finished product. Whether it’s a small renovation or a complete home build, we oversee our trusted network of carpenters, plumbers, electricians, and other specialists to ensure the highest standards of quality and service from start to finish.

PROJECT EXCELLENCE

 

JS Build was founded in 1987 by Jim Willsmore as a small, family-run business in the Adelaide Hills, specialising in home alterations and additions. In 2004, Jim’s son, Scott, took the reins and has since guided the business into a new era of growth, expanding into larger-scale projects including full home builds, major renovations, and custom extensions.

While we’ve grown, our values remain the same. We pride ourselves on delivering a personalised building experience, fostering strong, collaborative relationships with our clients. At JS Build, attention to detail is second nature - whether it’s a small addition or a complete new home, we are committed to quality craftsmanship, open communication, and a building process built on trust and transparency.

OUR PROCESS

At JS Build, we believe that the greatest need for any homeowner is clear, honest information. That’s why we operate with a cost-plus system — an open-book approach where every cost is shared with you at its true value. No hidden margins. No fine print. Just full transparency.

This means you’ll always know exactly where your budget is going, fostering a genuine, trustworthy partnership between builder and client. Every build is tailored to suit your individual needs and circumstances, ensuring a process that feels fair, collaborative, and aligned with your vision.
