How to get a pergola built in Bengaluru
A pergola goes up once and stays for years. We read the quotes and terms of four Bengaluru builders. Three of them are listed at the end. We read the 11 pergola requests people sent us since April. Here's what each roof costs a square foot and what the extra money buys. We also cover whose permission you need and how to keep the rain out.

How much does a pergola cost in Bengaluru?
At one Bengaluru builder's own rates, a 12 by 12 ft pergola with a Mangalore tile roof comes to about ₹1.1 lakh to ₹1.16 lakh with labour and transport, or about ₹1.29 lakh to ₹1.37 lakh with 18% GST. Ask whether the labour line covers carrying it all up to a terrace. For a smaller pergola, ask a local welder for a steel frame with a polycarbonate sheet.
Ask the seller
A shade sail, a net or a bought gazebo
Usually the cheapest shade: no welding, nothing drilled, and it leaves with you. Shade only, so most rain gets through
Ask a local welder
Polycarbonate sheet on a local welder's frame
A welder usually prices the frame by its steel and his days, and the sheet goes on top. The sheet alone is ₹200 a sq ft plus GST at Ingenium Designs, fitted on a frame you already have. Ask what area it's billed on
From ₹550 a sq ft
Insulated puff sheet on a steel frame
Misty Garden Weldscape. An opaque insulated panel, which they say keeps the heat out
₹635 to ₹680 a sq ft
Mangalore double tile on a steel frame
Misty Garden Weldscape. Terracotta tiles in two layers, which they say keep the heat out
Ask for the price
10 mm toughened glass on a steel frame

₹1,300 to ₹2,400 a sq ft

Which roof is best for a pergola: glass, tile, puff sheet or polycarbonate?
For a cooler, darker sit-out you'll use on April afternoons, or one over a bedroom, pick Mangalore tile or puff sheet. Pick glass or clear polycarbonate for the light, and the heat comes in with it. Slats or open louvres give shade and let the rain through.
Under a tile roof
Shade and warm colour. Glass tiles let a little light in
Under a glass roof
Bright, with the sky overhead. Fans for the heat
Why does one glass pergola cost more than another?
A 12 by 12 ft glass pergola from an aluminium maker is ₹2.56 lakh to ₹2.85 lakh before GST, by height. A steel frame is usually the cheaper frame: one Bengaluru fabricator's price guide puts steel at ₹900 to ₹1,500 a sq ft and fixed aluminium at ₹1,200 to ₹1,800. We found no steel builder's own price for a glass roof, so ask two welders for one at your size and set it beside this one.

Do I need permission to build a pergola on my terrace?
In a flat, get the association's yes in writing before anyone comes to measure. The state's apartment law needs every other owner's consent for a new structure on a shared roof, unless your sale deed gives you the terrace. On a house's own terrace, no rule names an open pergola, but walled in, expect it to need a licence like a room. In the garden or over the car, a pergola on posts can't stand in the open space your plan leaves around the house.
Will a pergola leak, or damage the terrace under it?
Before you sign, ask how the wall joint, the roof screws and the bolt holes through your terrace waterproofing will be sealed. Have the slab looked at on the site visit before tile or glass goes on it. A roof doesn't stop rain blowing in from the sides, so ask for side sheets too.
What does a pergola's per sq ft rate cover, and what comes extra?
The rate covers the roof and its fitting. Before you compare two quotes, add labour and transport, any clearing and civil work, and GST. On one Misty Garden Weldscape quote, labour was ₹13,000 and transport ₹5,000 (the table below). Three of the four builders here take about half before work starts, so get the payment schedule in writing.
How long does a pergola last, and who fixes it if it leaks?
Get in writing who comes back if the roof leaks in the first monsoon: no builder here promises to fix a leak. The steel frame ages first, from rust at the welds and the base, so ask what paint goes on it and how often it needs repainting.
Before you pay, settle these eight
- Which area the rate is on, and the size in sq ft
- Whether labour, transport, clearing an old roof and GST are in the number
- How the posts are fixed, and how holes through the waterproofing are sealed
- How the wall joint is sealed, which way the roof slopes and where the gutter drains
- The paint on the frame: which kind and how many coats
- In a flat, the association's yes in writing
- Who comes back if it leaks in the first monsoon, in writing
- How many days the work takes
