Mark Davis Design

What Mark Davis Design does

Mark Davis Design is a sole-proprietorship building design practice operated by founder Mark Davis, a Certified Passive House Designer and accredited Building Designer with over two decades of professional experience. The firm is based between the Blue Mountains and South Coast of New South Wales, Australia, and delivers custom home design services specialising in Passive House (Passivhaus) performance standards adapted for Australian climate conditions, including bushfire-prone zones. Core services span Passive House Design, custom Building Design, Renovations and Extensions, Passive House Consulting for architects and builders, specialised Bushfire Building Design, and technical Drafting Services for council approval and construction documentation.

The firm applies the five Passive House principles — super insulation, airtight construction, thermal bridge-free design, high-performance triple-glazed windows, and mechanical ventilation with heat recovery (MVHR) — using PHPP (Passive House Planning Package) software for energy modelling across Australia's eight climate zones. It has developed specialised methodologies for reconciling Australian Standard 3959 bushfire compliance with airtight, high-performance construction, including condensation management in BAL-FZ (Flame Zone) sites. Projects are supported by a partner ecosystem of bushfire consultants, structural engineers, energy assessors, Passive House Certifiers, private certifiers, and trusted builders.

The business operates on a sales-led, project-based professional services model. Revenue is generated through quote-based fees determined after an initial consultation and design brief review, with no publicly disclosed standard pricing. The go-to-market relies on a content-led website, organic social presence on Facebook and Instagram, SEO targeting NSW sustainable building queries, and client testimonials driving word-of-mouth referrals. Customer segments include primary individual homeowners in NSW (Sydney, Blue Mountains, Central Coast, South Coast, Shoalhaven, Illawarra) and a secondary business segment of architects, building designers, and builders seeking Passive House consulting. The firm has no external investment, no parent company, and operates as a privately held sole proprietorship with 1-10 employees.
