Modern aluminium pergola on a rooftop terrace with louvre roof

Service Profile · Pergola Awning

The terrace, finally. Used twelve months a year.

A motorised aluminium pergola with operable louvres that rotate from flat-open sky to fully sealed against the monsoon. Bioclimatic specification, sized for Mumbai terraces, podium decks and villa courtyards. Built so the outdoor room is actually outdoor — and actually a room.

Chapter 01 · The Problem

A terrace paid for.
Used three months a year.

A typical Mumbai penthouse — Worli, Bandra, Juhu — has a terrace the family paid for as part of the flat. They sit on it in winter for ten weeks. The other forty-two it is too hot, too wet, too dusty, or simply forgotten. The brief is rarely a roof. The brief is a terrace that gets used.

Outdoor furniture only earns its place when the roof above it is honest about Mumbai weather.

A fixed RCC roof

Solves the rain, ruins the sky. The terrace becomes a room, the view becomes a wall, and the society approval becomes a year-long fight.

ii.

A fabric awning

Looks fine in the photo, sags by the second monsoon, rots by the third. The motor seizes, the fabric stains, the whole assembly has to come down.

iii.

Or simply nothing

And the terrace stays unused — too hot at noon, too wet at five, too dusty at midnight. The most expensive room in the flat, lived in the least.

iv.

The fourth answer

A motorised aluminium pergola — louvres that rotate from open sky to monsoon-sealed in fifteen seconds. The terrace is the terrace, weather chosen on a remote.

Chapter 02 · How it works

Four parts.
One remote.

An aluminium frame

6063-T6 columns and beams, sized for the bay. Up to 6 × 4 m on a single span before we add an intermediate post. Powder-coat or anodise to any RAL — typically matched to the parapet finish or the joinery inside.

The louvres themselves

Extruded aluminium blades, 200 × 30 mm, set in the roof plane. They rotate from 0° (flat-open, full sky) to 135° (overlapped, monsoon-sealed) on a 24V tubular motor. Indian-spec or Somfy on request.

An integrated gutter

Concealed inside the perimeter beam. The louvres in their closed position drain into it; the gutter drains through the column down to the existing terrace outlet. No exposed pipe, no monsoon overflow on the deck.

—

Rain sensor.
LED edge-light.
Drop-down side screens.

A rain sensor closes the louvres automatically when the first drops hit. LED strip in the perimeter beam for evening use. Optional drop-down screens for full enclosure when the wind turns.

Chapter 03 · Material

What it’s made of.
Down to the gasket.

Specified for Mumbai monsoon, salt air and the dust that follows the dry months. Same alloy family as our slim-section windows. The motor and sensors are sealed for IP-rated terrace duty.

Material 01

The frame and louvres — 6063-T6 aluminium.

Extruded 6063-T6 columns, beams and 200 × 30 mm louvre blades. Powder-coat or architectural anodise to any RAL. Salt-air durable on sea-facing terraces in Worli, Bandra-West and Juhu without sacrificial coating.

Stainless steel motor and hardware close up

Material 02

The drive — 24V tubular motor.

Somfy or Indian-spec 24V tubular motor inside the louvre spine. Rated for 20,000+ cycles. Wired through the perimeter beam — no surface conduit. Optional rain sensor and wind sensor on the same controller.

Material 03

The hardware — SS 304 throughout.

Every fastener, bracket and hinge pin is SS 304. Integrated aluminium gutter and downpipe through the columns. EPDM gaskets on the louvre joints — replaceable in service, not sealed shut.

Chapter 04 · Where it’s installed

Real terraces.
Real weather. Real use.

Penthouse terraces in Worli, Bandra and Juhu. Villa courtyards in Alibaug and Lonavala. Restaurant outdoor seating in Bandra-West, Khar and Lower Parel. Podium pool decks. Family bungalow rear gardens. Builder podium club lounges. Anywhere the brief is an outdoor room that has to perform in monsoon.

Chapter 06 · Benefits

A pergola earns the terrace.
The louvres earn the pergola.

Louvres that rotate 0–135°.

Flat-open at noon for the breeze, angled at four to throw shade across the seating, fully overlapped at five when the cloud rolls in. The roof reads the day, not the other way around.

Motorised, with a rain sensor.

A 24V tubular motor closes the bay in fifteen seconds. The optional rain sensor closes it before the family does, which matters when the monsoon arrives at three in the afternoon and nobody is on the deck.

Integrated gutter handles monsoon.

The closed louvres drain into a perimeter gutter concealed in the beam, then through the columns to the terrace outlet. No surface pipe, no overflow on the seating, no second-floor neighbour complaints.

LED edge-light for the evening.

A continuous LED strip set into the perimeter beam. Warm-white as standard, dimmable, on the same controller as the louvre. The terrace is usable at nine without table lamps.

Weather-tight when shut.

Overlapping louvre profiles with EPDM gaskets close to a sealed plane. Tested against Mumbai monsoon load. The deck stays dry, the cushions stay dry, the dinner stays on the table.

Drop-down side screens on demand.

Optional aluminium-tracked drop-down screens at the perimeter — clear PVC for the wind, mesh for the mosquito, fabric for full enclosure. Used as needed, retracted when not.

Bays up to 6 × 4 m on a single span.

No intermediate columns inside the seating zone for the typical Mumbai penthouse terrace. Larger spans handled with a coupled bay structure — coordinated with the structural engineer at design stage.

Designed for a 15-year aluminium life.

Powder-coat or anodised 6063-T6 frame. SS 304 hardware. Sealed motor in the louvre spine. The maintenance regime is annual — a clean of the gutter, a check of the gasket, a wipe of the rain sensor.

Designer-direct.

Suraj reads the drawing, walks the terrace, signs off the shop drawing before fabrication. No franchise, no call-centre, no rep filtering technical questions. The relationship is the brand.

Chapter 07 · Common questions

The questions a designer
asks before the quote.

Most do, because the structure is demountable — bolted to the parapet or on a footplate, not cast into the slab. We provide a one-page specification sheet for the secretary stating that nothing is welded to the structure and the assembly can be removed in two working days. This usually clears the bye-law cycle in a single meeting.

Yes. The louvres overlap by 15 mm with EPDM gaskets at the joint. Closed-position water lands on the louvre, runs to the perimeter beam, into the integrated gutter, down through the column, into the existing terrace outlet. We've installed on Worli sea-facing penthouses where the wind drives the rain horizontal — the deck stays dry.

Around fifteen seconds for a 5 × 4 m bay from full-open to fully sealed. A rain sensor closes it automatically before the storm front arrives. A wind sensor — optional — opens the louvres flat at sustained gusts above 60 km/h to release wind load.

6063-T6 with a powder-coat or architectural anodise will hold ten-plus years on a Worli or Juhu sea-facing terrace without sacrificial coating. The hardware is SS 304, the motor is sealed inside the louvre spine. We specify a heavier coating thickness on coastal jobs as standard.

Up to 6 × 4 m on a single span. Larger than that we add a slim mid-column or a coupled bay structure, depending on the geometry. Send the terrace plan and we will mark the column positions on the drawing before quoting — no surprises at install.

6–8 weeks from drawing approval — most of that is fabrication time. Install on site is typically 5–7 working days, including the electrical and the rain sensor commissioning. We schedule the pour-test for water-tightness before handover.

Pricing depends on bay size, finish, side-screen scope and motor specification. Send the terrace plan or the bay dimensions and we will quote within three working days. We do not publish a per-square-foot rate — a 4 × 3 m courtyard pergola and a 6 × 4 m sea-facing penthouse cover are different conversations.

Send the drawing

Send the terrace plan.
We’ll quote in three days.

No site-visit fee. No call-centre. No quote written before measurement. Suraj walks the terrace himself, reads the parapet, marks the column positions, and signs off the shop drawing before we fabricate.

If the terrace is in a society building, ask for our one-page bye-law clearance note for the secretary — it covers the demountable specification and saves a meeting.
