Modular Kitchen Design: Layout, Carcass, Cost

Free preview · The work triangle, and when to ignore it

A kitchen is three activities with a machine at the centre of each: storage (fridge), washing (sink), cooking (hob). Draw a line between the three and you have the work triangle. The classic rule says each leg should measure between 1200 and 2700 mm and the perimeter should total between 4000 and 7900 mm. Shorter and you are colliding with yourself; longer and you walk a marathon to make chai. The rule was written for a Western kitchen with one cook. Indian cooking often has two people working at once, a separate wet area for washing utensils, and a grinder or a second burner that needs its own counter. So treat the triangle as a diagnostic, not a commandment. What matters more in practice are the three working zones and the counter that sits beside each one: - Beside the hob: at least 450 mm of landing counter on one side, ideally 600 mm on both, for hot vessels coming off the flame. Never put a hob within 300 mm of a return wall or a tall unit — the flame scorches the shutter edge. - Beside the sink: 600 mm on the draining side. This is where washed steel stacks up and it is always underestimated. - Beside the fridge: 300 mm minimum landing, on the handle side, so you can set down what you just took out. Walkways decide comfort more than any of this. A single-cook aisle needs 900 mm clear; a two-cook aisle or a parallel kitchen needs 1050 to 1200 mm. Below 900 mm two people cannot pass, and a dishwasher or oven door cannot open fully. Measure from the face of the shutter, not the wall — a 600 mm deep base unit plus a 20 mm shutter eats 620 mm before you begin. Finally, sequence the zones in the order the work flows: fridge to sink to prep to hob to serving. Most bad kitchens are not badly built; they are correctly built in the wrong order.

The carcass is the box you never see and the thing that fails first. In India the decision is almost always about water. BWP (Boiling Water Proof) plywood, IS:710 grade, is the default for base units and anything within a metre of the sink. It holds screws well, tolerates repeated wetting, and a 18 mm sheet is structurally stable over a 900 mm span. It is also the most expensive and the most counterfeited — insist on the IS:710 stamp along the edge and on a branded sheet, because plenty of "BWP" ply is BWR ply with a marker pen. BWR plywood is water resistant, not waterproof, and is honest value for wall units and tall units in a dry zone. MR (moisture resistant) grade belongs nowhere in a kitchen. HDHMR (high density high moisture resistance board) is dense, dead flat and takes a membrane or lacquer finish beautifully, which is why shutter factories love it. It is heavier than ply and holds screws less well over repeated removal, so use it for shutters and fixed panels rather than for hinge-bearing carcass sides that will be serviced. MDF is flat, cheap and machinable, and it swells irreversibly the first time standing water reaches an unsealed edge. Confine it to wardrobe interiors and shutter substrates in dry areas. WPC and PVC boards are genuinely unaffected by water and increasingly used for sink units. They are softer, creep under sustained load, and need shorter shelf spans — 600 mm rather than 900 mm — plus metal support for anything heavy. Particle board is for flat-pack furniture, not for a kitchen you expect to last a decade. A sensible hybrid, and what most good studios actually build: BWP ply carcass throughout the base, BWR ply above, HDHMR or ply shutters, and WPC only for the sink unit bottom and back. Specify the core material per unit in your schedule, not as a single line for the whole kitchen — that single line is how a sink unit ends up in MDF.

Free preview · Shutter finishes and where each one belongs

The shutter is 70 per cent of what the client sees and most of what they touch, so specify it by behaviour, not by name. Laminate on ply or HDHMR, 0.8 or 1 mm, is the reliable default. It is hard, cheap, endlessly varied, and repairable in the sense that a damaged shutter can simply be re-laminated. Its weakness is the edge: a PVC edge band lifts with steam if the glue is poor, so specify 2 mm bands laser-edged or at minimum hot-melt applied on a machine, never hand-ironed. Acrylic gives a high-gloss mirror face with excellent scratch resistance for a gloss finish, and it holds colour under sunlight far better than gloss laminate. It shows every fingerprint. Never use it on a shutter that opens under a window in a south-facing kitchen with hard water spray nearby. PU (polyurethane paint) on MDF or HDHMR is the finest looking and most fragile. It is the only way to get a true matte custom colour with a seamless edge, and it chips on impact and cannot be spot-repaired convincingly. Reserve it for wall units and tall units, and keep it away from the base run where mop handles live. Membrane (vacuum-pressed PVC foil over routed MDF) gives shaker profiles and curves in one seamless skin with no edge band at all. It delaminates at the corners in sustained heat, so avoid it directly beside an oven or a hob. Veneer belongs on a kitchen that is visible from a living room and is prepared to be treated gently; specify a melamine or PU topcoat and accept that the colour will move over five years. Glass and aluminium-framed shutters break up a long run of wall units and are worth the cost for exactly that reason. Use lacquered or frosted glass rather than clear unless the client genuinely keeps tidy shelves.

Free preview · Counters, cut-outs and the dado

The counter is the one element that cannot be swapped out later without disturbing everything around it, so it is decided with the carcass, not after. Material. Granite remains the default in India for good reason: it is heat tolerant, hard, cheap relative to the alternatives, and available in long slabs. Specify 18 to 20 mm thickness, machine-polished, with a mitred front edge if you want the look of a thicker slab. Quartz (engineered stone) is non-porous, stain resistant, and available in consistent pale colours that granite cannot offer; it is not heat proof, and a hot kadhai set directly on it will mark. Sintered stone handles heat and stains but costs more than most kitchens can carry. Stainless steel is the professional choice and reads as a commercial kitchen in a home. Avoid solid-surface acrylic anywhere a hot vessel lands. Counter height should be set from the primary cook, not from a standard: elbow height minus 100 to 150 mm, which for most users lands between 850 and 920 mm. If two cooks differ by more than 100 mm, split the counter height across the run rather than compromise at the average. Cut-outs. A sink is undermount (glued below, clean counter, requires a hard stone), top mount (dropped in with a rim, easiest and most forgiving) or integrated. Undermount is worth the cost for one reason only: you can sweep water straight into the bowl. Whichever you use, the sink unit below must have its top panel omitted, the carcass sides protected with a WPC or foil liner, and a removable bottom tray. For the hob, follow the manufacturer cut-out dimension exactly, keep 50 mm clear between the cut-out and the front edge, and 60 mm at the back. Dado. The 500 to 600 mm strip between counter and wall units takes the most abuse in the kitchen. Options in order of durability: full-height tile with minimal grout joints, toughened back-painted glass in a single piece (best for cleaning, expensive, and dimensions must be measured after the counter is installed), or a stone upstand matching the counter. Whatever you choose, run a silicone joint where the counter meets the dado — a grouted joint there will crack within a year as the carcass settles. Lighting: an under-cabinet LED strip at the front edge of the wall unit bottom, behind a 20 mm downstand so the diode is never seen, at 3500 to 4000 K and a minimum CRI of 90. It is the cheapest line item in the kitchen and the most noticed.
