Design & Build
While IDB is primarily a build-only contractor, we also offer a fully integrated Design & Build service-ideal for clients seeking a single point of contact to streamline the process from concept to completion. Whether you need us to handle specific design components or manage the entire journey, we tailor our delivery model to meet your unique project requirements.

Our Design & Build service includes:
- Early Contractor Involvement (ECI)
We begin with a collaborative planning phase to gain a clear understanding of your vision, operational needs, and key priorities. This early involvement helps de-risk the project, improve cost visibility, and align stakeholders from the outset. - Full Design Service
Our recommended consulting Designer/Architect works closely with you to develop a detailed space plan that reflects both aesthetic and functional goals. This includes:- Joinery and cabinetry design
- Kitchens and bathrooms
- Electrical and lighting layouts
- Media and technology requirements
- Furniture planning and selection
- Pre-Construction Project Management
We offer professional guidance through the consenting process, budget control, and programme planning. Our Quantity Surveying team provides regular cost updates reconciled with the evolving design, giving you clarity and control before construction begins.
- Design Sign-Off & Consent
Construction does not proceed until both design and budget are finalised and approved. Once confirmed, we manage the Building Consent process and transition the project smoothly into the construction phase.
Why Choose Design & Build?
A Design & Build contract is essentially a negotiated procurement method that offers higher levels of certainty around cost, design, and delivery timeframes. It allows for early alignment between the client, design, and construction teams—resulting in a more agile, transparent, and cost-effective build.
At IDB, our philosophy is built on collaboration. Whether we’re working with your existing architect or engaging our own team of designers, we prioritise partnership and open communication to ensure the best possible outcome.
