House Construction Cost on 2.5, 3, 4 and 5 Aana Plots in Kathmandu Valley (2026)

In Kathmandu Valley, if you have a 3 aana plot and would like to build a normal 2.5 storey house, it will cost you about NPR 61 lakh to NPR 91 lakh for a midrange construction and higher if you would like to have a quality finish. Beyond 4 aana, and same house style, the price range is around NPR 83 lakh to 1.24 crore. Those numbers are a simple chain: the plot you get dictates what you can build; the built up area times your finish tier dictates what it costs.

This guide takes the reader through the chain for 2.5, 3, 4 and 5 aana plots. It reveals how much floor area you can expect from each plot, the price of each tier of finishes you can expect to pay, the hidden costs of quotes, and how to convert a planning quote into a quote you can stand behind.

What is the area of each plot in square feet?

The conversion table in the government's building by-laws reference book says that 1 aana is equivalent to 342.25 sq ft while 16 aana is equivalent to 1 ropani, which is equivalent to 5,476 sq ft. That gives you:

Construction cost is a cost of built-up area, not plot area. A 4 aana plot is 1369 sq ft of land but you will not construct 1369 sq ft of house. Your footprint will be smaller and you'll stack floors above one another.

What is the capacity of each plot of land?

This is determined by three rules: ground coverage; setbacks and floor area ratio (FAR).

According to the same book, the 4 sizes of plots here can occupy as much as 70 per cent of the plot for residential buildings. Doors or windows are at least 1.5 m (5 ft) back from the side of a neighbour on the property side and at least 1.5 m (5 ft) back from the right of way of a local road. Setback is increased for taller buildings (after 10 m). The ratio of the total floor area to the plot area (FAR) is determined by the local government and varies from ward to ward and road to road, even in Kathmandu, Lalitpur and Bhaktapur.

In practice, most footprints are below 70 percent as staircases and setbacks remain in place – along with space on the roadside. A good rule of thumb for plotting is the 65% approximation for a footprint. If a 2.5 storey house (2 full floors and a half storey/floor), then the numbers are like this:

Planning figures only, not permit figures. Before the drawings are submitted, your architect will verify the actual footprint and number of floors with your ward's rules.

The cost of building as related to size and degree of completion of the plot.

The cost of construction in Nepal for 2026 is between NPR 2,800 and NPR 8,000 per square foot, depending on the level of finishing. The cost of our houses is divided into three categories: basic houses between NPR 2,800 and 3,700, standard houses between NPR 3,700 and 5,500 and premium houses at NPR 5,500 and above. These rates are applied to the built-up areas above to give the following planning estimates for a 2 ½ storey house in the Kathmandu Valley:

The estimate for two full floors and a half floor is this:

An interesting observation here is that, under these assumptions, the standard-finish 2.5 storey house comes to the same price of NPR 20 to 31,000 per aana in all four plot sizes. That's a neat guideline but it only works because the coverage, number of floors and finish level were all the same in each case. Change any of those and the figure per aana moves. The size of your land is not the cost of your built-up area or finish.

The implications of each size plot

2.5 aana

This plot is approximately 79.5 sq m at the edge of the national by-laws reference book which includes a minimum plot size of 80 sq m for residential plots. If you already have the plot, check with your ward or municipality if it can be permitted and what is required locally. After the setbacks have been removed, the footprint is a small box approximately 20 x 28 ft. Stairs occupy a significant portion of each floor, along with two bathrooms and a kitchen, making rooms quite cramped, and creating the half floor as a potential prayer room or study. The range of fixed costs, like the staircase, kitchen and bathroom fittings, is similar for a small house and a big house, and tends to fall towards the top of the tier for small plots.

In Kathmandu Valley, if you have a 3 aana plot and would like to build a normal 2.5 storey house, it will cost you about NPR 61 lakh to NPR 91 lakh for a midrange construction and higher if you would like to have a quality finish. And the same house style, the price range is from NPR 83 lakh to 1.24 crore, past 4 aana. Those numbers are a basic chain: If you have a poor plot, you will have an inferior product; if you have a good plot and a poor finish tier, you will have an inferior product.

This book guides the reader through the chain of 2.5, 3, 4 and 5 aana plots. It uncovers the amount of floor area you can anticipate to get from every plot, the expense of every level of finish you can anticipate having to pay, the hidden expenses in quotes, and how you can transform a planning quote into a quote you can stand behind.

How many square feet of land are in each plot?

The conversion table in the government's building by-laws reference book says that 1 aana is equivalent to 342.25 sq ft while 16 aana is equivalent to 1 ropani, which is equivalent to 5,476 sq ft. That gives you:

Construction cost is a cost of built-up area, not plot area. A 4 ana plot is 1369 sq ft of land as you will not build 1369 sq ft of house. Your footprints will be reduced in size and you'll be stacking the floors on top of each other.

How many square metres are there in each plot?

This is done based on 3 rules: ground coverage, setbacks and floor area ratio (FAR).

The same book states that in residential buildings up to 70 per cent of plot can be taken up by the 4 sizes of plots here. A minimum distance of 1.5 m (5 ft) away from the side of another neighbour on the side of the property and a minimum distance of 1.5 m (5 ft) away from a local road right of way. Taller buildings (after 10 m) have increasing setback. The ratio of the total floor area to the plot area (FAR) is determined by the local government and varies from ward to ward and road to road, even in Kathmandu, Lalitpur and Bhaktapur.

In practice, most footprints are below 70 percent as staircases and setbacks remain in place along with space on the roadside. The 65% approximation of a footprint is a good rule of thumb to plot. If a 2.5 storey house (2 full floors and a half storey/floor), then the numbers are like this:

Only planning figures and not permit figures. Your architect will confirm the actual footprint and level of floors prior to the drawings being submitted with your ward's rules.

The price of building in relation to size and stage of completion of the plot.

The cost of construction in Nepal for 2026 is between NPR 2,800 and NPR 8,000 per square foot, depending on the level of finishing. Our houses are categorized based on their price into three groups: NPR 2,800 for basic houses, NPR 3,700 for standard and NPR 5,500 or more for premium houses. These rates are applied to the built-up areas above to give the following planning estimates for a 2 ½ storey house in the Kathmandu Valley:

The cost of two full floors and a ½ floor is this:

An interesting point here is that, on the above assumptions, the standard end finish 2.5 storey house costs NPR 20 to 31,000 per aana in all four plot sizes! That's a nice rule, but only works because coverage was the same in all cases and the number of floors and finish level were the same. With just a single change, the figure changes per aana. The size of your land does not equal the cost of your built-up or finished area.

The implications of each size plot

2.5 aana

The area of this plot is about 79.5 sq m. on the edge of the national by-laws reference book that stipulates a minimum plot size of 80 sq m for residence plots. If you already have a plot, contact your ward or municipality to see if you can obtain permission and what is needed in your area. Once the setbacks are taken away, the footprint is quite small, a small box about 20 x 28 ft., with a large proportion of stairs, two bathrooms and a kitchen, the latter is available to use as a prayer room or study the half floor. The range of fixed costs, like the staircase, kitchen and bathroom fittings, is similar for a small house and a big house, and tends to fall towards the top of the tier for small plots.

Conclusion

Plot size in aana tells you the ceiling on what you can build, but the money is decided by built-up area and finish level. For a standard 2.5-storey house, budgets run from around NPR 52 to 77 lakh on 2.5 aana to about 1.04 to 1.54 crore on 5 aana, before land, permits, design and furnishing. Use these figures to shortlist what is realistic, then replace them with a BOQ based on your own drawings.
