Building terrace houses is an excellent way to maximise land potential and achieve economies of scale. But without smart planning, costs can quickly escalate.
Here’s how homeowners and developers can build more efficiently without compromising quality.
1. Keep It Simple
Complex shapes, multiple rooflines, and unusual angles add significant labor and material costs. Stick to rectangular footprints with straightforward roof designs to reduce structural complexity and waste. Using standard modular designs also makes procurement and installation much easier.
2. Prefabricated Components & Modular Builds
Off-site manufacturing—such as wall panels, roof modules, or entire volumetric sections—can significantly cut build time and labor expenses. Prefabrication often reduces costs by 10–25% and speeds up construction by up to 50%. A faster build also minimises weather-related delays, further saving time and money.
3. Design for Efficiency
Efficient design means maximising function in minimal space. Open-plan layouts, reduced circulation areas, standard-sized windows and cabinetry—all reduce material use and installation time. Planning service zones (like kitchen and bathrooms) in close proximity cuts plumbing and electrical install lengths, saving considerable costs .
4. Source Materials Smartly
Buying materials directly and in bulk can yield substantial savings. Purchasing flat-pack joinery, pre-cut timber, or off-the-shelf windows often costs significantly less than sourcing bespoke fittings . Focus premium finishes in high-traffic areas, while using cost-effective materials—like corrugated steel—for less noticeable zones.
5. Timing & Labour Strategies
Labour can account for 30–40% of a build’s cost. Consider DIYing non-licensed tasks (like painting, cladding, or installing joinery) while still hiring professionals for critical systems. Also, scheduling your build during off-peak seasons may help you negotiate better rates with tradespeople and suppliers.
6. Use Smart Tech for Budgeting
Modern takeoff and estimating software can sharply reduce errors and help you uncover hidden cost-saving opportunities. Tools like Buildxact can evaluate material use, labor hours, and costs upfront—so you can refine your design and save before the build kicks off.
7. Leverage Land Efficiency
Build on level or uncomplicated sites to avoid expensive earthworks or retaining walls. Multiple terrace homes on one property can share services and infrastructure, spreading costs more advantageously than standalone houses.
8. Invest in Quality When It Counts
Not all savings are equal. Poor-quality bases—like flooring, plumbing, or waterproofing—may seem cheaper initially, but lead to expensive maintenance or rework later. Prioritize quality in foundational areas and choose savings in trim, paint, or fittings .
By taking a strategic approach to design, materials, labour, and technology, you can build terrace homes both cost-efficiently and to a high standard. Avoiding complexity, embracing prefabrication, smart material sourcing, and modern takeoff tools puts your project on a path to financial success and sustainability.
