Sloping & Complex Sites
Builders for Sloping & Complex Sites in Melbourne.
Steep blocks, heritage overlays, tight access, engineered, approved and built end-to-end.
What this service is
The blocks other builders walk away from.
Sloping and complex sites need a builder who's solved them before. Steep falls, battle-axe access, heritage overlays, BAL zones and reactive soils all add engineering, approvals and construction complexity that a standard builder isn't set up for.
Demardi runs these projects end-to-end: feasibility, engineering, design, approvals and construction, so the site is solved properly from day one, not patched on the fly.
The Demardi Difference
Our core strength: building where it's hard.
- Decades of experience on sloping and complex sites across Melbourne
- Coordinated engineering (structural, civil and geotech) from day one
- Planning, heritage and overlay approvals handled in-house
- One dedicated supervisor on site through to final handover
- Real-time client portal access for the whole program
- Fixed pricing before construction begins, with no creeping site-cost variations
The Process
From first site walk to handover.
Step 1
Site Assessment
We walk the block, review overlays, slope, access and services, and give you a clear-eyed feasibility view before you commit.
Step 2
Engineering & Design
Structural, civil, geotech and design teams work together from day one so the home and the site are solved as one project, not two.
Step 3
Approvals
Planning, building and overlay approvals managed end-to-end, with a fixed contract price before construction begins.
Step 4
Build & Handover
Construction with your dedicated supervisor on site, real-time client portal updates, and a finished home handed back ready to live in.
Demardi Client Portal
Track every milestone, photo and decision in real time.
Every Demardi project comes with private access to our client portal. Photos, schedule, selections, payments and direct communication with your supervisor, all in one place, so you're never left guessing where things are at.
Who this is for
This is the right fit if…
- Your block has slope, overlays, tight access or other site complexity
- You want a builder who's done this before, not one learning on your job
- You're investing in a high-end home and need the site handled properly from day one
"We had a superb experience and result with our renovation in Mitcham this year. We chose Demardi based on their professional social media and their work looked amazing. Right from our initial meeting, Anthony understood our vision and expertly fleshed out our ideas and found things we hadn't thought of that would improve the result."

Frequently asked
The questions homeowners ask us most.
What counts as a sloping or complex site?
+
It covers quite a range: steep falls, battle-axe blocks, tight or restricted access, heritage overlays, bushfire attack level (BAL) zones, reactive or expansive soils, significant easements, or sites with substantial vegetation to navigate. Essentially, anything that brings engineering, council or construction complexity that a standard builder isn't set up to handle well.
Do sloping sites really cost more to build on?
+
Generally, yes, and we think it's important to be upfront about that early. Excavation, retention walls, engineered footings and managing site access all add to the build cost on a complex block. We'll give you a clear picture of the site-cost picture in our first feasibility conversation, so you're not designing a home around a budget that doesn't account for the site you're actually on.
Can you assess a block before we buy it?
+
Absolutely, and we'd encourage it. We regularly walk potential sites with clients and prospective buyers to give a practical view on slope, overlays, services, access and likely site costs before any money changes hands. It's a straightforward conversation that can save a lot of headaches down the track.
Who handles the engineering and council side?
+
We do, end-to-end. We coordinate the full specialist team, including structural and civil engineers, geotechnical consultants, surveyors and town planners, and we manage all council and overlay approvals on your behalf. You don't need to chase down separate consultants or translate between them; that's our job.

Complex site, but still need design?
