What actually drives the cost of a home extension or renovation? 💷
If you're thinking about extending your home, you've probably noticed quotes can vary wildly. Here's what really impacts pricing and why you shouldn't just chase the cheapest option.
🏗️ Project scope & complexity—A simple rear extension costs less than a two-storey build with structural work. Dormer lofts cost more than Velux conversions. Complexity = higher labour and engineering costs.
📐 Materials & finishes—high-spec kitchens, or luxury bathroom fittings. Your choices here make the biggest difference.
🔧 Site conditions—Ground conditions, access, existing utilities, and structural requirements all add cost. A straightforward build on good ground costs less than one requiring piling or major replumbing.
📋 Planning & building control—Some projects need planning permission; others don't. Compliance work, inspections, and engineer fees are real costs that protect your investment.
👷 Labour & expertise—Experienced tradespeople, project management, and quality oversight cost more—but they deliver better results, fewer delays, and fewer problems down the road.
⏰ Timeline—Rushed projects cost more. Proper scheduling, material ordering, and coordination keep costs down and quality up.
The bottom line? The cheapest quote often means cutting corners on materials, labour, or oversight. A quality build costs more upfront but delivers better value, fewer headaches, and a home you'll love for decades.
