Describe your house and explore an indicative estimate, down to concrete and steel quantities. This data-informed planning tool draws on Structa’s experience across more than 2,000 projects and a selected historical priced residential dataset. It is not a measured BOQ or a current tender quote.

No terrace, boundary wall, security, design package or price escalation is included.
Example total: LKR 25,570,688

How this estimate is built
This data-informed tool draws on Structa’s experience across more than 2,000 projects. Its numerical model uses a selected set of historical priced residential records—not every project Structa has delivered. For each trade it estimates quantities per square metre of floor, bathroom or storey, then applies historical rates.
Your inputs scale those quantities. Rates are historical medians from the supplied model, and finishing-material allowances reflect different client budget levels. Material and labour prices can change; ask Structa to verify current rates for your site before making financial decisions.
The ±25% display is an illustrative planning band, not an accuracy guarantee. A site-specific measured BOQ is needed before financial decisions.
Rates used
Not included
Land, legal fees, and local-authority approval fees.
Soil investigation and special foundations such as piles. Weak ground needs an engineer’s assessment.
Ceilings. Structa’s standard finish is a painted concrete soffit.
Air conditioning, solar panels, landscaping, furniture and kitchen appliances.
Swimming pools and other one-off features.
Common questions
How much does it cost to build a house in Sri Lanka in 2026?
Historical residential median LKR 11,520 per sq ft; middle half LKR 9,772 to LKR 12,812 per sq ft. This includes major construction and finishes, but excludes land and approval fees.
How accurate is this calculator?
It is an early planning tool, not a quotation. The ±25% band is illustrative, not a guarantee. Ask Structa for a measured BOQ based on your drawings and site.
Why can two houses of the same size cost differently?
Storeys, bathrooms, roof, soil and finishes change the price. A third bathroom adds about LKR 255,675 to this typical example.
What is not included?
Land, approval fees, soil investigation, special foundations, ceilings, air conditioning, solar, landscaping, furniture and appliances.
