Choosing between a single storey and a two storey house is one of the biggest decisions you will make when building your dream home in Sri Lanka. Both options have clear advantages and disadvantages. The right choice depends on your land size, budget, family needs, and future plans. In this guide, we break down everything you need to know so you can make a smart decision.

Advantages of a Single Storey House

A single storey house is the traditional choice for many Sri Lankan families. Here is why it remains popular.

Disadvantages of a Single Storey House

Advantages of a Two Storey House

A two storey house is becoming more and more popular in Sri Lanka, especially in urban and semi-urban areas. Here are the benefits.

Disadvantages of a Two Storey House

Cost Comparison: Single Storey vs Two Storey

Many people think a two storey house costs exactly double. That is not true. A two storey house typically costs about 15% to 25% more than a single storey house with the same total floor area. Here is a general cost comparison for the Matale, Kandy, and Gampola areas.

Feature Single Storey Two Storey
Cost per sq ft (standard finish) Rs. 7,500 - 9,500 Rs. 8,500 - 11,000
Foundation cost Lower 20-30% higher
Roof cost Higher (larger area) Lower (smaller area)
Staircase cost None Rs. 350,000 - 600,000
Land needed for 2,000 sq ft home 10 - 15 perch 6 - 10 perch
Construction time 4 - 6 months 6 - 10 months
Privacy level Lower Higher
Resale value Good Very good

Which is Better for Your Family?

There is no single answer that works for everyone. The best choice depends on your family situation.

Young Family with Children

A two storey house works well. Children enjoy having their own rooms upstairs, and the ground floor stays tidy for guests. Just make sure to add safety gates at the top and bottom of the staircase when the children are small.

Family with Elderly Parents

A single storey house is the safest option. If you still want a two storey house, plan a bedroom with an attached bathroom on the ground floor for your parents. This way, they never need to use the stairs.

Small Plot (Under 8 Perch)

A two storey house is almost always the better choice for small plots. Building upwards gives you the space you need without covering every inch of your land. You still have room for a small garden and parking.

Large Plot (Over 15 Perch)

If you have plenty of land, a single storey house gives you a spacious and comfortable home on one level. You can spread the rooms out, add wide corridors, and still have a large garden and outdoor space.

Land Size Guide: When to Go Single vs Two Storey

Here is a simple guide based on land size in perch. This applies to typical residential plots in Matale, Kandy, Akurana, and Gampola.

The Smart Hybrid Option: Build Now, Expand Later

Not sure if you need two floors right now? There is a smart solution. Build a single storey house today, but design the foundation and columns strong enough to support a second floor in the future.

This hybrid approach is very popular in Sri Lanka. You save money now and add the upper floor when your family grows or your budget allows. The key is to plan for this from the start. If the foundation is not strong enough, you cannot safely add a second floor later.

At Unicon Construction, we design many homes with this future expansion in mind. We make sure the structural work on the ground floor can handle the extra weight of a second floor. This small extra investment during the first build saves you a lot of money compared to rebuilding the foundation later.
