What's Actually Possible (Feasibility)

Feasibility is the question "can this actually be done, in this building, within these rules, for money I have?" - asked deliberately, item by item, before commitment. It is not a single yes or no but a structured reconciliation of your brief with five hard realities: the building's structure, its services, the space available, the approvals that govern it, and the money you can spend. A wish is feasible only if it survives all five. Most briefs contain a mix: some items sail through, some need adapting, and a few turn out to be impossible as stated and must be rethought or dropped. The job of a feasibility check is to find out which is which while it is still cheap to change your mind.

The reason this matters so much in renovation specifically - far more than in new-build - is the through-line of the whole course: you are working on an existing building full of unknowns and fixed constraints. A new design can put anything anywhere and then engineer it; a renovation inherits load paths, drainage runs, floor levels, a plot boundary, a society's rules and a budget already partly eaten by the unglamorous must-haves. Feasibility is how you map those constraints onto your wishes so that what you commit to is real. It is the difference between a client who is told "that wall is load-bearing, so an open kitchen needs a beam and will cost this much more" at the planning stage, and one who discovers it with the wall half-down and the budget already spent.

Crucially, feasibility is a professional-assisted exercise, not a solo guess. You can and should do a first-pass check yourself - it sharpens the brief and flags the big risks - but the binding answers on the dangerous items come from the right professionals: whether a wall is load-bearing and how to open it from a structural engineer; what approvals and society NOCs apply from the local authority and legal advice; realistic costs from a quantity surveyor or experienced contractor. Treat your own check as the screening that tells you which questions to take to whom, and every figure in it as illustrative, as of 2026, until a professional confirms it for your building.

The first three tests are about the physical building, and they are where most renovation wishes succeed, adapt or die. Structure asks: will the building allow this change to what holds it up? Removing or opening a wall, adding a floor, cutting a big opening, loading a slab with a new bathroom - all depend on whether the element is load-bearing and whether the structure can take the new forces. In an old load-bearing masonry house almost every thick wall may be doing structural work; in a modern RCC-framed flat the frame carries the loads and many internal walls are mere partitions - but you must never assume which is which. This is the headline deferral of the whole course: a qualified structural engineer confirms what is load-bearing and designs any change to it. Module 3 is devoted to this.

Services asks: can water, drainage, power and ventilation actually reach where you want them? This is the test people most often forget, and drainage is the usual villain, because waste pipes need a continuous downward fall to a fixed connection point - so a bathroom or kitchen you want to move may simply be too far, or too level, to drain without pumps or dropped ceilings. Water supply, the electrical board's capacity, gas routing and extract ventilation all have similar fixed logic. Moving a wet room is rarely just a matter of taste; it is a services problem first. Licensed plumbers and electricians give the binding answers, but the feasibility habit is to ask, for every wet or powered item you want to move, *where does it connect, and can a pipe or cable sensibly get there?*

Space asks the most literal question: does it physically fit, at the right dimensions, with the ceiling height, door swings, circulation and light a real room needs? A loft with too little headroom, a kitchen island that leaves no working gap, a bedroom that meets no minimum once you add a wardrobe - these fail the space test regardless of structure or services. Sketching the wish at real dimensions, on a measured plan, is often enough to reveal that the dream does not fit, or fits only by sacrificing something you promised to keep. Structure, services and space together decide whether the building can host your wish at all.

The last two tests are about permission and payment, and they are the ones optimistic renovators most often postpone until it is too late. Approvals asks: are you actually allowed to do this? Renovations touch a web of rules - local building regulations and the building code, planning or municipal permission for extensions and external changes, and, for flats, the housing society or association's own rules and the need for a No-Objection Certificate. Heritage listing adds another layer entirely. Some changes need formal approval before work begins; some need neighbour consent; some - especially to shared structure or the external envelope in an apartment - may simply not be permitted. The feasibility habit is to identify, early, which of your wishes touch the external envelope, shared structure, drains or the plot's footprint, because those are the ones that need checking with the local authority, the society and legal advice before you bank on them. Never assume a permission; verify it.

Money is the test that quietly governs all the others, because structure, services, space and approvals can all usually be solved - at a price - and the real question is whether that price fits your budget. A feasibility check costs the scheme at a realistic, rough order of magnitude: not a precise quote, but an honest "is this a ten-lakh idea or a forty-lakh idea?" against what you can actually spend, with the non-negotiable contingency for surprises built in. Renovations are notorious for cost overruns precisely because people skip this reconciliation and discover the gap after committing. The point of costing at feasibility stage is not accuracy - that comes later with a quantity surveyor or detailed quotes - but to catch the wishes that are simply in the wrong budget bracket while you can still adjust the brief.

Together, approvals and money are where many technically-possible renovations meet their real limit. A thing can be structurally sound, serviceable and space-efficient and still be forbidden by the society or unaffordable within contingency. Testing all five lenses - not just the exciting physical ones - is what makes a feasibility check honest rather than a wishful sketch that ignores the two realities most likely to stop you.

A feasibility check ends not with a sketch but with a verdict on each wish, and there are only three: go, adapt, or stop. *Go* means the wish survives all five tests roughly as stated - the building allows it, services can reach, it fits, it is permitted, and it is within budget with contingency; you can carry it into the plan with confidence. *Adapt* is the most common and the most valuable outcome: the need is real and achievable, but not in the form first wished - the open-plan becomes a wide beamed opening because the wall is load-bearing; the moved bathroom stays put but is reconfigured because drainage will not reach; the extension shrinks to fit the permission. This is exactly where the last lesson pays off: because you named the *need*, not just the solution, you can trade the solution while keeping the need. *Stop* means the wish cannot be met in this building within these rules and this budget, and the honest, money-saving thing is to let it go now rather than fight a losing battle through demolition.

The emotional work here is real, because *adapt* and *stop* can feel like defeats, and a good designer frames them as the opposite. Every wish redirected at feasibility stage is a disaster avoided later - a budget protected, a structural risk averted, an approval refusal pre-empted. The renovator who hears "that cannot be done as you imagined, but here is how we meet what you actually wanted" is being served well, not thwarted. Reconciling vision with constraint is not the death of the vision; it is the only way the vision actually gets built.

And the verdict has a timing that is the whole point of the lesson: it must come before commitment. Before you instruct demolition, before you pay a designer to detail a scheme that cannot be approved, before you order materials for a layout that will not fit. Feasibility is the last cheap moment in a renovation - the final stage where changing your mind costs only a conversation and a sketch. Spend that moment well, get the five verdicts, take the dangerous questions to the right professionals, and you cross from wishing into a plan you can actually build. Skip it, and the building will deliver the verdicts anyway - later, more expensively, and without mercy.
