Many homeowners are surprised when they discover that two houses of the same plot size and built-up area can have very different construction costs. A 2,000 sq. ft. home built on one plot may cost significantly more—or less—than another 2,000 sq. ft. home just a few streets away.

So why does this happen?

The answer lies not in size, but in construction decisions, engineering depth, material quality, and long-term planning. Let’s break it down simply.

1. Foundation Design Depends on Soil, Not Square Feet

Two plots of the same size can sit on completely different soil conditions.

• Soft or loose soil requires deeper foundations

• Black cotton or water-retentive soil needs special treatment

• High water table areas demand additional waterproofing

A stronger foundation means:

• More excavation

• More concrete and steel

• More engineering input

All of this directly increases cost—but also prevents settlement and cracks in the future.

👉 Homes that look identical above ground may be very different below ground.

2. Structural Strength: Columns, Beams & Slabs Matter

Some homes are designed only for current needs. Others are designed to handle:

• Future floors

• Heavy interiors

• Long-term structural safety

Key cost-impacting factors include:

• Column spacing

• Beam thickness

• Slab design (solid slab vs ribbed slab)

• Grade and quantity of steel

A structurally stronger home costs more upfront—but saves massively on:

• Repairs

• Retrofitting

• Structural risks later

3. Quality of Materials Makes a Huge Difference

Not all materials are equal—even if they look the same.

Examples:

• Branded cement vs local alternatives

• TMT steel grades (Fe500D vs lower grades)

• Manufactured sand vs untested river sand

• Branded waterproofing chemicals vs basic solutions

Using higher-grade materials increases initial cost but delivers:

• Better durability

• Fewer cracks

• Lower maintenance

• Longer life

Cheap materials often mean hidden future expenses.

4. Design Complexity Affects Cost More Than Area

Two homes of equal size can have very different layouts:

• Simple rectangular plans cost less

• Multiple cut-outs, projections, curves cost more

• Double-height spaces increase structural demand

• Cantilevers and large balconies require extra reinforcement

Even ceiling height matters:

• Higher ceilings = more material + stronger structure

Good design is not about being flashy—it’s about balancing aesthetics with construction efficiency.

5. Construction Method & Supervision Level

The way a home is built affects cost just as much as what is built.

Cost varies based on:

• Skilled labor vs untrained labor

• Engineer-led execution vs contractor-only execution

• Regular quality checks vs minimal supervision

• Proper curing time vs rushed timelines

Well-supervised projects may cost slightly more but deliver:

• Better finish

• Stronger structure

• Fewer defects

• Peace of mind

6. Waterproofing, Insulation & Hidden Systems

Many cost differences come from things you don’t see after construction:

• Terrace waterproofing systems

• Bathroom and kitchen damp-proofing

• External wall weather protection

• Heat insulation for roofs

• Anti-termite treatments

Skipping or minimizing these saves money initially—but often leads to:

• Leakage

• Damp walls

• Mold

• Frequent repairs

A well-built home invests in protection, not patchwork.

7. Finish Quality Is Only One Part of the Cost

People often assume tiles, paint, and fittings are the main cost drivers. In reality:

• Finishes are visible, but structure is foundational

• Premium homes invest more in engineering than decoration

Two homes may use similar tiles, but one may have:

• Better load distribution

• Superior waterproofing

• Stronger foundation

• Longer life expectancy

That difference reflects in cost.

8. Long-Term Thinking vs Short-Term Budgeting

The biggest reason for cost variation is mindset.

• One home is built to last 15–20 years

• Another is built to last generations

Cutting corners reduces initial cost—but increases:

• Maintenance expenses

• Repair stress

• Structural risks

Quality construction is not an expense—it’s an investment.

Final Thoughts

Two homes of the same size can cost very differently because construction is not just about area—it’s about engineering, materials, execution, and foresight.

At Shyam Constructions, residential projects are planned with:

• Site-specific engineering

• Long-term durability in mind

• Transparent material choices

• Strong structural foundations

Because a home should not just look good on day one—
It should stand strong for decades.
