Second Storey Extension Costs Richmond 2026
Complete pricing guide for all extension types and budgets

Quick Answer
Second storey extensions in high-density Richmond typically cost $240,000-$540,000 for standard builds. Smaller block sizes mean building upward is often the only option for additional space. Expect additional costs for boundary setback engineering, overshadowing analysis, and potential party wall agreements with neighbors. Master suite additions start from $180,000-$264,000.

1
Boundary Setbacks: Critical in high-density Richmond - most councils require 0.9-1.5m minimum from side boundaries, affecting upper level footprint
2
Overshadowing Analysis: Mandatory - new upper levels cannot increase shadowing to neighboring properties beyond council limits
3
Material Delivery Access: May require crane hire ($2,000-$5,000/day) for tight block access and hoisting materials over existing structures
4
Party Wall Agreements: With neighbors may be required where new construction adjoins or affects shared walls
5
Light-Optimizing Design: Strategically placed windows, skylights, and light wells maximize amenity on constrained Richmond blocks
6
ROI in High-Density Richmond: Typically 80-95% due to limited land availability and strong demand for family-sized homes

Why Add a Second Storey to Your Richmond Home?
Looking for second-storey extension builders near you in Richmond? The Wombat™ connects Richmond residents with licensed builders throughout the Greater Melbourne region.
Second-Storey Extensions in High-Density Richmond: High-density suburbs with expensive land make second-storey extensions highly cost-effective. Limited block sizes prevent ground-floor expansion, making upward building the only option. Challenges include narrow block access, neighbor proximity requiring privacy screening, strict height limits, and heritage overlays in character areas. Popular designs maximize space efficiency with open-plan living, master suites with views, and careful window placement for privacy while capturing light. Our Richmond builders specialize in narrow-site construction and space-efficient designs for high-density living.
All builders in our Richmond network are fully licensed, understand Melbourne council regulations, and provide structural engineering coordination.
