Practices looking for a construction partner who respects design intent, solves complexity and communicates clearly.

In-house registered Architect (30+ years in Melbourne)
Specialising in architecturally driven, detail-rich builds
Every project is different, but the standard is the same: meticulous planning, honest advice and uncompromising execution.
Custom homes and knockdown/rebuilds in Melbourne’s most established suburbs, built to showcase your architect’s vision – not dilute it.
Townhouses and small multi-residential projects for developers who want a premium product, efficient construction and a smooth settlement.
Engage GADCON early and work with our in-house Architect and construction team from feasibility through to handover.
Founded by David Gadalla, GADCON exists to close the gap between ambitious design and on-site delivery. After more than a decade delivering complex multi-residential projects with leading Tier 1 and Tier 2 builders, David created a firm where:
Paired with an in-house registered Architect with over 30 years’ local experience, GADCON brings rare alignment between drawing board and construction site.
Every detail is deliberate.
Each project is a study in collaboration, precision and restraint.
Arbour is a boutique duplex development defined by contemporary lines, natural materials and a functional five-bed, 3.5-bath, double-garage layout crafted for modern family living.
Eston is a refined duplex development defined by strong geometric forms, crafted detailing and a functional five-bed, 3.5-bath, double-garage layout designed for elevated everyday living.
Kew Terrace Homes is a collection of four contemporary town residences in the heart of Kew, combining modern architectural form with the ease of inner-city living. Designed for refined urban lifestyles, each home balances thoughtful planning, quality materials and a clean, modern aesthetic.
Park Ave is an architecturally designed rear-lot development created through a targeted partial demolition to form two contemporary townhomes. Each residence offers four bedrooms, three bathrooms and a single garage, defined by bold forms, refined materials and a focus on modern, functional living.
Our process keeps architecture, cost and delivery in sync from day one.
We begin with a detailed conversation about your site, budget, brief and professional team. We review concept drawings or ideas, flag risks early, and provide an honest view of feasibility.
Working alongside your architect — or leading design through our in-house Architect — we coordinate consultants, refine details and continuously align scope with budget and program.
Once on site, you’ll see disciplined site management, clear communication and rigorous quality checks. We handle the build, defects period and handover with the same care as the design.
You’ll always know where your project stands, what comes next, and why.
We focus on architecturally designed custom homes, boutique developments and select industrial/commercial builds. If your project is design-led and quality-driven, we’re happy to talk.
No. We regularly work in two ways — with external architects, or via our in-house Architect under a design + construct model. If you’re not sure where to start, we can advise on the best path.
The earlier, the better. Involving us at concept stage allows us to advise on buildability, budgets and staging before drawings are locked in, saving time and variations later.
We use industry-standard contracts and can work under lump sum or cost-plus arrangements, depending on the project. During pre-construction we’ll clarify cost structure and reporting so there are no surprises.
Our focus is greater Melbourne and nearby regions for the right project. If you’re unsure, share your site and we’ll let you know quickly.
For clients and collaborators who want to go deeper, we share practical insights on budgets, design coordination and build quality.
