Open plan is default for modern Gold Coast homes — but done badly it results in noisy, hard-to-cool spaces that lack privacy. Here’s how to get it right.
Large openings for natural ventilation, indoor-outdoor flow for subtropical lifestyle, natural light filling deep floor plans, entertaining flowing between kitchen, living, dining, and outdoor living areas.
Kitchen is the anchor. Island bench provides workspace, seating, and natural boundary. Dining adjacent to kitchen and outdoor area. See our kitchen design guide for layout options.
Visual separation from kitchen through ceiling height change, different flooring, furniture placement, or feature wall focal point.
Connected through large sliding doors. When open, three zones flow as one. When closed, each functions independently.
Bowling alley: Long narrow open plan feels like a corridor. Need minimum 5-6m width.
No acoustic retreat: Nowhere to escape noise. Include separate media room or home office nook.
Kitchen mess on display: Butler’s pantry or raised benchtop screens the work surface.
Inadequate storage: Open plan exposes clutter. Built-in cabinetry essential.
Ignoring acoustics: Hard surfaces create echo. Incorporate rugs, upholstered furniture, timber ceilings.
Removing load-bearing walls requires structural beams. Brick walls: $5,000-$15,000 per wall. Timber walls: $3,000-$8,000 per wall.
Large open spans require steel or engineered timber beams. Longer spans cost more but eliminate columns. For renovation costs, see our complete renovation pricing guide.
Ceiling fans everywhere — over dining, living, and kitchen areas.
Zoned air conditioning — ducted with zones so you cool only what you’re using.
Thermal separation — insulated walls between living and bedroom wings. See our guide on sustainable home design for more on passive cooling.
Retractable screens — for storms, security, and temperature control.
Minimum 50-60sqm for standard family home. 70-90sqm for larger homes.
Usually yes. Budget $20,000-$60,000 for wall removal, structural work, and finishing. See our guide on renovation vs knockdown rebuild to decide the best approach.
Yes — larger rooms with more glass are harder to rate. Good design overcomes this. See our guide on NatHERS energy ratings.
Depends on lifestyle. Most modern Gold Coast homes are moving away from formal lounges.
Standard 2.7m for smaller areas. 3.0-3.6m for larger spaces (70sqm+). Raked ceilings add drama.
Open plan works on the Gold Coast when designed with intent — defined zones, acoustic retreats, climate-responsive features, and adequate storage. Design it, don’t just remove walls.
