USING SMART AND DURABLE MATERIALS
Home additions builders recommend using smart, durable materials such as cladding, high-quality insulation, and a roofing structure designed to resist moisture, heat, and salt-laden winds. They prefer the following materials for second story additions or home extensions in Sydney.
Fibre-cement or metal cladding for better moisture resistance
Colorbond roofing to handle wind and temperature swings
High-performance insulation to control indoor comfort
Treated framing timber to avoid warping in coastal suburbs
These materials provide unmatched strength to any extension right from the ground up, improve energy efficiency, and ensure complete protection against temperature fluctuations.
THINKING SERIOUSLY ABOUT STORM PROTECTION
Home builders should pay more attention to storm protection, as sudden downpours are very common in this city. They can overwhelm a poor drainage system, and strong winds will show their impact if the structure is weak or poorly planned. Homeowners must plan oversized gutters, secure roof tie-downs and get proper site grading done. They should also invest in higher-quality window seals to prevent leakage during stormy weather.
These steps taken in advance will keep the property protected from water and damage caused by typical East Coast lows.
THERMAL CONTROL
Thermal control is another important consideration when designing home extensions in Sydney, or even second-storey additions. This is mainly because the upper floors heat up faster than other parts of the property. You can achieve better comfort in second-storey additions with some common installations like –
Double-glazed windows
Light-coloured roofing
Cross-ventilation planning
Roof sarking to reduce radiant heat
