Walk into almost any unrenovated Melbourne heritage home on a winter's day and the problem announces itself before you've taken your coat off. Beautiful from the street. Fifteen degrees inside when it's 22 outside.

In this episode, builder Simon Clark answers one of the most common questions he hears from Melbourne homeowners: can you really have the soul of a heritage home and the thermal comfort of a modern one? After nearly 50 heritage renovations, his answer is an emphatic yes.

Simon opens with the building science behind why heritage homes fail. Double brick walls may be less leaky than weatherboard, but without insulation they push the dew point onto internal surfaces, breeding mould. Single-glazed windows offer virtually no thermal barrier. Dark interiors were never designed with passive solar in mind. The charm is real. So is the discomfort, and the health risk.

He then walks through five building fabric upgrades SHM applies to heritage renovations: addressing compromised footings using resin injection and board piers, replacing lightweight subfloors with an insulated infill slab and low carbon concrete to create genuine thermal mass, installing Coolfirm K17 insulation-backed plasterboard internally on double brick walls using the dop and dab method, rebuilding roofs with OSB, vapour-permeable membranes, and ventilated counter battens to allow moisture to disperse rather than condensate, and restoring or upgrading heritage windows, including vacuum insulated glass units for lead light windows council will not permit to be replaced.

Each upgrade is designed to work within heritage overlay constraints, keeping council happy while transforming the building from the inside out.

You'll learn:

• Why double brick heritage homes often develop mould problems, and the building science behind it
• The infill slab method SHM uses to eliminate subfloor moisture and create thermal mass with low carbon concrete
• How Coolfirm K17 insulation-backed plasterboard transforms double brick wall performance without touching the exterior
• Why vapour-permeable membranes and ventilated roof battens outperform traditional roof blankets
• How to upgrade lead light and heritage-listed windows without breaching council requirements
• How to genuinely improve thermal comfort and longevity while working within heritage overlay constraints

Who it's for: Owners of Melbourne heritage homes planning a renovation or extension, architects and designers working within heritage overlays, and anyone who has wondered whether you really have to choose between character and comfort.

Most buyers spend weeks inspecting kitchens and bathrooms. But when you're buying an inner-city Melbourne property to renovate, extend, or knock down and rebuild, the things that will make or break your project often aren't visible on the surface.

In this episode, builder Simon Clark walks through the essential due diligence checklist for anyone buying a property with major works in mind; from orientation and VicPlan overlays to flood levels, combined sewers, site access, and the eras of homes most likely to hide expensive surprises behind their walls.

Simon explains why orientation is the single biggest factor most buyers overlook, and what it actually costs to fix a home with north to the front. He covers how to read VicPlan, what to ask council's planning department before you commit to a purchase, and why updated flood mapping across inner Melbourne is quietly adding cost and complexity to more renovation projects than buyers realise.

He also unpacks the construction realities that matter before you sign: legal point of discharge, sewer easements, combined sewers in older inner suburbs, overhead electrical, and site access for machinery. Plus the ResCode trap that catches buyers who confuse what a neighbouring property built decades ago with what council will permit today.

Finally, Simon addresses budget head-on: realistic square metre rates for inner-city Melbourne renovation and new builds, why double brick is more challenging to renovate than most buyers expect, and how a proper feasibility plan with a builder early in the process can protect you from the most costly mistake of all.

You'll learn:

• Why orientation is the single most important factor to check before buying, and what north to the front really costs to fix
• How to use VicPlan and what to ask council's planning department before you commit
• Why flood levels are affecting more inner Melbourne properties than buyers realise
• The era of homes most likely to conceal structural surprises behind their walls
• Realistic square metre rates for inner-city Melbourne renovation, extension, and knockdown rebuild
• How a feasibility plan with a builder early in the process can prevent the most costly outcome in design

Who it's for: Homeowners considering buying an inner-city Melbourne property to renovate, extend, or knockdown rebuild, and anyone who wants to approach purchasing a property with a builder's eye for what actually matters, not just what looks good on inspection day.

Better insulation should mean a healthier, more comfortable home—but if it’s not paired with the right moisture management, it can quietly create the conditions for mould, rot, and “leaky home” failures. 

In this episode, builder Simon Clark unpacks Leaky Building Syndrome (catastrophe's in New Zealand and Canada) and explains why Australia’s push toward energy-efficient homes can backfire when builders don’t understand drainage planes, ventilated cavities, vapour diffusion, and humidity control. 

Simon breaks it down simply: modern wall systems are no longer “hollow and forgiving.” Once insulation fills the cavity, moisture can get trapped—so you need a wall that can shed water, drain it, and dry it. He shares SHM’s practical five-part approach: keep water out, don’t rely on cladding to be waterproof, use vapour-permeable membranes, build ventilated cavities for drying, and actively manage indoor humidity (increasingly with heat recovery ventilation / HRV). 

You’ll also hear the homeowner questions that reveal whether your builder truly understands building science: What happens when water gets behind the cladding? How does it dry? How are you controlling humidity inside the home? 

You’ll learn:

• Why insulation changes the moisture game (and how walls can become “moisture traps”) 
• The difference between cladding as a rainscreen vs a real waterproofing strategy 
• What vapour-permeable membranes do (the “Gore-Tex jacket” concept) and why older sarkings are being phased out 
• How ventilated cavities create drying pathways behind cladding—and why they’re non-negotiable 
• How much water vapour households generate daily—and why HRV can be the difference between comfort and condensation 
• The 3 questions to ask your builder to avoid hidden long-term risk 

Who it’s for: Homeowners planning a new build or renovation (especially higher-insulation, higher-airtightness projects), architects/designers, and anyone wanting a healthy, durable, moisture-safe home—not just a pretty one.

Building your home is exciting—but once construction starts, your property becomes a workplace, and that changes everything. 

In this episode, builder Simon Clark explains exactly what you should expect from your builder during the construction phase and what “good process” looks like when dozens of trades and suppliers are working hard to bring your new home or home renovation to life.

Simon unpacks the construction essentials that protect both your build and your sanity—clear communication, a proven system, respect for your time and property, and a contract that acts as the project playbook (there’s no “good bloke clause”). He also demystifies the parts of the contract homeowners most often misunderstand: variations (owner-initiated, builder-initiated, and regulatory), prime cost vs provisional sum allowances, and how progress payments work for custom builds.

Finally, he walks through the handover and defects process—including why SHM strongly recommends an independent private building inspection at practical completion to catch the details that statutory inspections often miss, and how defect periods and warranties actually play out over the first 3–6 months in a live home. 

You’ll learn:

• Why your builder must control site access (and what you should expect to stay informed)
• The construction principles you should demand: transparency, process, respect, aftercare
• The 3 types of variations—and how to avoid nasty surprises
• Provisional sums vs prime cost items (and how adjustments really work)
• Progress claims for custom builds: what “stage complete” looks like in reality
• Practical completion → independent inspection → defects list → handover (step-by-step)
• What changes in your home over seasons—and how defect periods/warranties help

Who it’s for: Homeowners planning a renovation or new build who want a clear, practical understanding of how construction runs—and how to protect quality, safety, and expectations from contract to handover.

What does a design–build journey actually look like—from first enquiry to a signed building contract? In this episode, builder Simon Clark walks through Sustainable Homes Melbourne’s proven process, step by step: Discovery Session at the Fitzroy studio → Design Kickoff on site (with re-establishment & feature survey) → a Feasibility Plan with project-specific sqm guidance → Concept Design with iterative reviews → a detailed Concept Estimate and specification → Planning management (if required) → full Design Documentation (engineering, energy assessment, soil tests, interiors) → Contract Estimate and contract signing. Along the way, Simon explains SHM’s four core standards—140 mm stud walls (R4), thermally broken timber/UPVC windows, Pro Clima vapour-permeable membranes, and HRV (heat-recovery ventilation)—and how they lift comfort, durability, and performance for Melbourne homes. 

You’ll learn:

• The complete SHM timeline: discovery, site kickoff, feasibility, concept, estimating, planning/docs, contract
• Why early estimating discipline prevents decision fatigue and keeps scope aligned with expectations
• How project-specific sqm rates differ by site type, location and finish level
• What’s included in documentation: structural & (where needed) civil engineering, energy, soil tests, interiors, and who appoints the building surveyor
• The performance basics every custom home should have: R4 walls, airtight/water-managed envelopes, HRV, thermally broken windows

Who it’s for: Melbourne homeowners planning a custom renovation or new build, plus architects/designers who want a clear, cost-literate path from concept to contract.

Should you renovate or knockdown-rebuild? In this episode, builder Simon Clark breaks down the 10 decisive factors that determine which route delivers better value, performance, and peace of mind—especially on inner-city Melbourne sites with heritage sensitivities. You’ll learn how ResCode, overlays and site conditions can force your hand, why floor levels and subfloors matter more than most people think, and when soil movement, drainage and access make a renovation risky (or a KDRB the cleaner, faster answer). Simon also shares practical investigations to run before you spend on design: council triggers, soil tests, plumber CCTV for sewer/stormwater, survey types, and three-phase power/electrical pit checks. 

You’ll learn:

• Planning & ResCode realities: how heritage/overlays and non-compliant existing walls affect a KDRB vs reno decision
• Block & access constraints: why machine access/orientation can make or break an extension
• Floor level & moisture: when to swap bouncy timber subfloors for an insulated infill slab (and save headaches)
• Soil movement & structure: screw piles, bored piers, underpinning, and the pitfalls of re-stumping done poorly
• Defects & unknowns: when large movements (e.g., 60 mm over a doorway) tip the scales to KDRB
• Scope clarity: keeping a clean “new vs existing” line to avoid labor-heavy blending
• Contingency planning: sensible ranges for renovations (≈10–20%) vs new builds (≈5–10%)
• Pre-design checks: exact council question to ask about planning triggers, plus CCTV sewer, stormwater fall, survey types, and power upgrades

Who it’s for: Homeowners weighing renovation vs knockdown-rebuild, architects/designers advising clients, and builders needing a clear, client-friendly decision framework.

In 2024, Simon toured Palm Springs — the mecca of mid-century modern and distilled five design lessons you can apply to Melbourne and broader Australian climates: (1) expressive textures (custom breeze blocks, screens, tactile floors) that also accelerate airflow; (2) right-sized plans with genuine indoor–outdoor connection from living rooms and bedrooms; (3) workmanship that respects details (what Elvis Presley’s “House of Tomorrow” gets wrong); (4) confident use of colour that adds delight without kitsch; and (5) climate-first planning — deep overhangs, shaded vestibule entries, cross-ventilation, and thermal mass — drawn from pre-air-con desert architecture and exemplified by Frey House II. 

Simon translates each move for Australian sites (think inner-city courtyards, roof/vertical gardens, mudroom-style airlocks, and ducting strategies) so your next renovation or new build feels cooler, calmer, and timeless not just trendy. 

You’ll learn:

• The desert playbook: shade first, then airflow, then thermal mass—and how to combine them
• How breeze blocks, screens, and courtyards accelerate natural ventilation
• Why smaller, smarter plans with storage beat oversized heat boxes
• Practical shading tactics: overhangs, external blinds, pergolas, and vestibule (air-lock) entries
• Ways to achieve indoor–outdoor connection without sacrificing performance
• When large openings help (and hurt) NatHERS — and how to design around it

Who it’s for: For lovers of mid-century Architecture. Homeowners, architects/designers, and builders seeking passive cooling strategies that translate Palm Springs principles to Australian climates — from inner-city terraces to suburban renovations.

Before you sign with any builder, ask this: “Are you comfortable with an independent building inspector inspecting your work?” 

In this episode, builder Simon Clark explains why that single question reveals more about a builder’s quality, confidence, and culture than any brochure ever could. He breaks down how Australia’s current system relies on brief statutory checks (footings, slab steel, frame… then a quick look at practical completion) and why a separate, third-party inspector—especially at practical completion—catches the details that matter to your family’s comfort, safety, and long-term maintenance. You’ll learn where inspections add the most value, common gaps (e.g., no mandated waterproofing inspection in Victoria), how to coordinate stage inspections without slowing site progress, and what a good defects list looks like when everyone’s working in good faith.

You’ll learn:

• The difference between a building surveyor’s statutory role and an independent inspector’s deep dive
• Why practical completion is the must-do moment for third-party verification
• How independent inspection improves outcomes across carpentry/frame, waterproofing, and finishes
• The exact wording to use when you ask builders about independent inspections—and how their response signals professionalism
• A simple QA rhythm: site manager → project manager → builder director → independent inspector for true peace of mind

Who it’s for: Homeowners planning custom builds or major renovations, and architects/designers who want real-world quality outcomes—beyond paperwork.

What is biophilic design—and does it really make a difference? 

In this episode, builder Simon Clark breaks down the science-backed benefits of bringing nature into the home and shares a practical, no-nonsense framework you can use on any renovation or new build (especially inner-city homes).

Simon covers why our brains crave daylight, views to greenery and gentle natural sounds—and how poor environments (think hard, echoey, unpredictable spaces) elevate stress. He then outlines five timeless biophilic principles you can apply without the “woo-woo” or gimmicks:

1. Orient to nature & sunlight — frame views to gardens/sky, prioritise north light, use skylights wisely.
2. Harness natural ventilation — design for cross-flow and operable openings (and actively use them).
3. Use natural materials with texture & warmth — timber, stone, brick, tactile finishes that feel human.
4. Create true indoor–outdoor connection — generous openings to decks/courtyards and everyday “escape” nooks.
5. Support biodiversity at home scale — roof/vertical gardens, planting that attracts birds, bees and butterflies.

You’ll also hear where energy modelling can clash with human comfort (e.g., big openings and NatHERS star trade-offs) and how to balance high performance with genuine wellbeing.

You’ll learn:

• Simple design moves that lower stress, improve mood and support sleep
• How to avoid dark, lifeless plans by insisting on light courts and framed views
• Why tactile, natural finishes change how a home feels and is used
• Practical ways to introduce greenery in tight urban sites (courtyards, roof/vertical gardens)
• The case for “active” home operation—opening windows/doors consciously

Who it’s for: Homeowners, architects/designers, and builders who want homes that perform and feel incredible to live in.

70 out of 10 custom home designs never make it to site - and the biggest reason is avoidable. 

In this episode, builder Simon Clark explains the #1 mistake homeowners make: engaging a designer or architect without bringing a builder in early. Simon shares a war-story from his early career (the “square-metre rate” tender) and lays out a smarter path: Early Contractor Involvement (ECI) at the most critical time in your design process.

You’ll learn how a reputable builder prices properly (not guesswork), builds a detailed spec and bill of quantities, and value-manages materials and selections so you can move into planning and interiors with cost certainty. 

He also covers why “free tenders” backfire, the real hours it takes to estimate thoroughly, and how ECI lets you test a builder out before you commit to a six or seven-figure build.

What you’ll take away:

• When the best time is to involve your builder via an ECI agreement
• What a good ECI delivers: comprehensive pricing, spec, BOQ, value-management
• Why “free” tenders and square-metre rates can lead you down the garden path to disappointment and frustration
• The true cost of delays vs. a $5k–$10k ECI agreement that could save you $100,000
• How ECI boosts buildability, budget control, and confidence from paper to site

Who it’s for: Homeowners, architects/designers, and anyone planning a renovation or new custom home.
