Indian Coffee House Thiruvananthapuram Case Study: Spiral Plan and Brick (Laurie Baker)

The Indian Coffee House at Thampanoor in Thiruvananthapuram (Trivandrum) is a round brick building by Laurie Baker in which the floor is one continuous spiral ramp. The ramp climbs around a circular service core, the tables line the outer wall, and that wall is pierced with rows of triangular brick jaali openings that let in light and air. This case study covers the brief, site, plan, section, materials, climate, use today and lessons, and says plainly what is not documented.

Indian Coffee House, Thampanoor: the facts

Architect: Laurie Baker (1917 to 2007). Baker built with his own team of masons and carpenters and never ran a conventional architectural firm, according to his official website. No separate structural engineer is named in the sources we read.

Operator: the signboard names the India Coffee Board Workers' Co-operative Society Ltd No. 4227, the Thrissur society whose area runs from Thrissur to Thiruvananthapuram. Who commissioned the building is not stated in any source we could open.

Location: Thampanoor, Thiruvananthapuram, Kerala, next to the KSRTC bus stand and opposite the railway station.

Designed and built: not documented in a primary source we could find. Baker's official list of works names the building without a year. Baker moved to Thiruvananthapuram in 1969, so the building dates from after that. The "ESTD 1958" on the signboard is the society's founding year, not the building's.

Type: coffee house and restaurant, popularly signed as Maveli Cafe.

Area and cost: not published in the sources we read.

Status: in use as an Indian Coffee House and open to the public as a restaurant.

Who designed the Indian Coffee House in Trivandrum?

The building is by Laurie Baker, the English-born architect who settled in Kerala. His official biography summary gives the outline: born in Birmingham in 1917, trained at the Birmingham School of Architecture, came to India in 1945 as chief architect of the Mission to Lepers, received Indian citizenship in 1988 and the Padma Sri in 1990. (Scroll, in 2026, gives 1989 for citizenship.) The same website says the family moved to Trivandrum in 1969.

The official site's page on COSTFORD says Baker "worked by himself, directly with his masons, carpenters and workmen". In his own account of the Trivandrum years, Baker writes that much of what came to be called Baker architecture he owed to these craftsmen. We found no record naming the masons or an engineer for this particular job.

The brief and the client: a workers' coffee house

The Indian Coffee House is not a private café chain. It began under the Coffee Board, and after the Board closed its coffee houses in the 1950s, workers took them over and ran them as cooperatives, as the Architecture in Development entry summarises. In Kerala, the Thrissur society's own history page says the India Coffee Board Workers' Co-operative Society was established on 10 February 1958, opened its first coffee house in Thrissur on 8 March 1958, and runs about 50 branches from Thrissur to Thiruvananthapuram. That 1958 date is the "ESTD 1958" you see on the Thampanoor signboard in a 2024 photo on Wikimedia Commons, and it is the likely reason the building is sometimes dated to 1958. It cannot be the building's date: Baker only moved to the city in 1969.

What the written brief was, who signed the contract and what the building cost are not in any source we could open. Baker's own description of how he started a design is the best guide to his approach. On the quotes page of his website he says he first wanted to know who the clients were, what they would do in the building, what the site and the weather were like, and how much money was to be spent, and that "the real inspiration comes from the person and the place and the function". For a coffee house at a bus and rail interchange, the function is plain: seat a steady flow of people in a hot, humid city on a small piece of land.

Site and context: Thampanoor

Thampanoor is the transport hub of Thiruvananthapuram. Outlook Traveller (20 November 2014) places the coffee house right next to the KSRTC bus stand, and Jeremy Smith's essay in Architecture New Zealand (March 2020) places it opposite the railway station. The surroundings today are dense: Commons photos from March 2024 show the drum hemmed in by shop fronts, hoardings on steel frames and a bus shelter. Against that background the round brick form reads clearly from the street, which helps explain why Onmanorama (May 2026) calls it one of the city's most beloved landmarks.

The plot area is not published in the sources we read, but the form goes up rather than out: a tower of seating on a tight footprint.

Indian Coffee House Trivandrum architecture: the design idea

The idea fits in one sentence: instead of a stack of floors joined by a stair, the whole dining room is a single ramp that winds up inside a brick cylinder. The Architecture in Development entry describes the building as a continuous spiral ramp with a central circular service core and dining space on the outer side. Outlook Traveller puts it from the customer's side: the floor ascends in a spiral, with built-in tables along the outer edge all the way to the top. Ajay Kamalakaran, writing in Onmanorama (December 2020), remembers the cafe's marble tables spread out along the ascending spiral.

This one move has two results. Circulation and seating become the same space, so no floor area is spent on a separate stair hall. And the building has no storeys in the usual sense: a 2023 article on KT Explorer by Anisha Rudrani makes exactly this point, noting that the inner side of the ramp works as a staircase without stairs.

The outside shows the spiral as tiers. Photos show the drum rising in stepped bands, each with its own projecting ledge, capped by a wide brim and a smaller cylinder on top. KT Explorer describes that top cylinder as giving the composition an asymmetrical balance.

Indian Coffee House Thiruvananthapuram plan: core, ramp and tables

We have not found published measured drawings of the building from an archive, and Baker's official site notes that he "rarely documented any of his work" in the usual way. So the diagram below is an MOA schematic of the plan principle, drawn from the written descriptions above, not a copy of any drawing. The number of turns and tables is illustrative.

Schematic plan diagram of the Indian Coffee House, not a measured plan: a circle of brick wall pierced by small triangular jaali openings, with a round service core at the centre; between them a red arrow enters from the street at the bottom and spirals around the core marked up, showing one continuous ramp; small tables line the outer edge against the wall; numbered notes on the right explain the service core, the spiral ramp with no separate storeys, tables on the outer side, the brick jaali wall and the street-level entry near the KSRTC bus stand — The plan idea in one drawing: a service core in the middle, one ramp wrapped around it, and the tables against the perforated outer wall. Diagram: MOA

Read the plan in three rings:

The core. A round service core sits in the centre; the sources do not list what it holds.
The ramp. The floor between core and wall is one sloping surface. Its inner edge, next to the core, is the route people walk up and down.
The tables. The outer edge, against the wall, is where people sit. No seat is far from light and air.

Commons photos also show a lower round block of the same brick beside the main drum, and the entrance is at street level. How the kitchen, counter and billing are arranged inside is not described in the sources we read, so the diagram leaves them out.

Section and structure

A spiral floor makes an unusual section. Cut through the middle and the ramp meets the core at a different height on each side, because each side is half a turn apart. The MOA diagram below shows that principle and the air path the sources describe. Heights and the number of turns are illustrative.

Schematic section diagram of the Indian Coffee House, not a measured section: a cylinder of brick wall with small triangular openings stands on street level around a tall service core; sloping ramp segments meet the core at different heights on the left and right, showing a spiral floor rather than storeys, with tables at the outer wall; grey arrows show air entering low through the openings, a dashed red line rises around the core, and red arrows leave through openings higher up and through a smaller drum on top — The section principle: because the floor is a spiral it meets the core at a different height on each side, and air can rise through the whole volume. Diagram: MOA

The structural system (how the ramp spans, how it is reinforced, how thick the walls are) is not set out in any source we could open, and we have not guessed at it. The descriptions give only the two fixed lines the ramp runs between: the outer brick wall and the central core. For a thesis, the structure is the gap worth filling with a site visit and permission to measure.

Materials and construction: exposed brick and jaali

The sources agree on the two materials that matter. The walls are exposed brick: Architecture in Development says the brickwork is painted white inside and brick-red outside, and Onmanorama (2026) describes a cylindrical spiral structure in exposed red brick. The openings are Baker's jaali. Architecture in Development says the jaalis serve as windows, bringing in light and helping ventilation. Kamalakaran describes countless triangular openings on the outer wall, and the photos show them as stepped triangles in the brickwork, set in rows between the ledges.

Outlook Traveller adds a point about the curved wall: it says the curve encloses more floor area for the same material than straight walls would, and calls this a hallmark of Baker's style. That is the writer's claim, quoted as such; we have no measured figure for this building.

Baker is also known for rat-trap bond walls and filler slab roofs, which COSTFORD, the organisation he chaired, lists among the elements it uses from his work. None of the sources we read ties either, or any roof build-up, to this building, so we do not claim them here. If you want those techniques, our red brick, AAC and fly ash comparison and our guide to building materials in Kerala cover how brick and laterite behave in the state's climate.

Light, climate and air

Thiruvananthapuram is warm and humid for most of the year. The building's climate strategy is the perforated wall and the tall open volume. Jeremy Smith's Architecture New Zealand essay says the building "literally spirals upwards, funnelling air like a corkscrew" and extracts it through open holes in the brickwork. He describes being served coffee against a "perforated brickwork veil, or jali" through which air moves.

Our reading of why that works: air comes in through openings low down, warms as the room is used, rises up the open spiral, and leaves through openings higher up and at the top. The jaali also shades. Each opening is small and set into a thick brick wall, so sun reaches the tables as patches of light rather than as glare. A photo of the interior on Wikimedia Commons shows the effect: white walls with rows of bright triangles, ceiling fans, and tables set along the curved wall. We found no airflow or temperature data for this building.

For more on how perforated brick screens work in Indian homes, see our post on jaali design for home.

Reception and the building today

Writers have treated the building with affection rather than as a monument. Smith (2020) reads the jaali as linking inside and outside, and says Baker builds with air as much as with physical materials. Onmanorama's May 2026 feature by Nitya Punnackal describes light moving through the jaali walls and interiors designed with care for climate, movement and human comfort, and treats the coffee house as more than a restaurant.

Problems are less well documented. We found no dated, named source on leaks, structural repairs, alterations or proposals to demolish the building, so we report none. What the March 2024 Commons photos do show is the drum's surroundings: hoarding frames and signboards fixed around and above it, and workers up on the roof and the frames. The building's future is tied to its operator. In August 2025 Onmanorama reported that the Thrissur-based society's network had shrunk from 59 branches and 2,300 staff at its peak to 45 branches and 1,450 employees, that 14 branches had shut, and that recruitment approval had been withheld for three years. The report does not mention the Thampanoor branch.

What designers in India can take from it today

These are our reading of the building, not claims from the sources.

Let circulation do the seating. On a small urban plot, a stair and landings can eat a large share of the floor. Here the route up is the dining room. For a café, canteen, reading room or gallery on a tight site, ask whether a continuous ramp or a split-level route can carry both movement and use. Check the slope and handrails against current accessibility norms before you borrow the idea: a ramp is step-free, but only a gentle one is usable by everyone.
Make one element do several jobs. The jaali wall is the window, the sunshade, the ventilator and the facade pattern at once, with no glass, grille or blind.
Give an everyday building a clear form. A cooperative coffee house at a bus stand is about as ordinary as a brief gets. Its round brick form made it a landmark that people name and photograph. Here the clarity comes from a plan idea, not from added cladding.
Document your own work. This building has no published date, plan or cost, because Baker rarely recorded his projects. If you want your buildings studied, keep dated drawings and photos. Our field checklist for documenting a building shows what a good record looks like.

Visiting and seeing the drawings

The building is a working Indian Coffee House at Thampanoor, next to the KSRTC bus stand, and you see it the way everyone else does: by going in and ordering. The society's website lists Thiruvananthapuram among its branch districts but does not print timings for this branch, so we do not give any. If you plan to sketch or measure inside for a studio project, ask the staff first.

We did not find measured drawings published by an archive. For Baker's own writing, principles and a list of works, start with his official website. The Laurie Baker Centre for Habitat Studies was set up by his friends and students for research and documentation of his approach and is the place to ask about records.

FAQ

Who designed the Indian Coffee House in Trivandrum?

Laurie Baker designed the Indian Coffee House at Thampanoor, Thiruvananthapuram. It appears on the list of works on his official website, and he built with his own team of masons rather than through a conventional firm.

When was the Indian Coffee House in Trivandrum built?

No primary source we found gives a year. Baker's official list names it without a date. It must be after 1969, when Baker moved to Thiruvananthapuram. The "ESTD 1958" on the signboard is the founding year of the cooperative society that runs it, not the building's date.

What is the plan of the Indian Coffee House Thiruvananthapuram?

It is a round brick drum with a circular service core in the middle and one continuous spiral ramp between core and wall. Tables run along the outer wall and people walk up the inner side of the ramp, so there are no separate floors.

Why is the Indian Coffee House building round with holes in the walls?

The holes are brick jaali openings that act as windows, bringing in light and air. Published accounts describe air rising through the spiral like a corkscrew and leaving through openings in the brickwork, which suits Thiruvananthapuram's warm, humid climate.

Where is the Laurie Baker coffee house in Trivandrum?

At Thampanoor, next to the KSRTC bus stand and opposite the Thiruvananthapuram railway station. It is still in use as an Indian Coffee House.
