Defence Colony is one of the oldest planned colonies in South Delhi, and its housing stock shows it. Most of what changes hands now is a builder floor in a building put up decades ago, often rebuilt once already, carrying services and a plan from an earlier era.
If you are looking for an interior designer in Defence Colony, here is what these floors need, what you will find behind the walls, and the constraints particular to this part of Delhi.
The typology
Defence Colony floors share their basic problem with Greater Kailash, South Extension and Panchsheel: a plot deeper than it is wide, light at the front and back only, a dark middle, a stair you did not choose, and a structure that is not moving.
That sounds limiting. In practice it leaves a great deal to design — because almost everything that determines how these homes feel is inside the fixed shell rather than outside it.
The dark centre
Give it to circulation, storage, a powder room or a utility. Put the rooms you live in at the front and back where the light is. Where the structure permits, a glazed internal partition or a clerestory opening can pull light across the depth of the floor and change the whole plan.
The stair and the entry
A narrow stair up the side of the building into a landing with nowhere to put your shoes is the standard condition. It is also the first and last thing you experience each day. A shallow partition or tall storage unit set a metre or so in from the door creates a real entry without losing meaningful area — closed shoe storage, a mirror, a surface, and a light on its own switch.
It is the cheapest intervention available in a floor like this, and the one you feel most often.
Ceiling height
Protect it. A full false ceiling with services can take a foot, and in a nine-foot room that foot is the difference between generous and oppressive. Drop the ceiling only where services run and leave the rest alone.
What you will find behind the walls
In a Defence Colony building of any age, assume at least two of these:
Wiring that cannot carry modern load. Undersized cable, no earthing, an inadequate distribution board, joints buried in walls. Full rewiring is the honest answer rather than a patch.
Plumbing at the end of its life. GI pipes corrode internally and run at a fraction of their bore by thirty years. Replace in CPVC or PPR while walls are open.
Failed waterproofing. Damp on the ceiling below, or salt bloom at skirting level. There is no surface cure — the bathroom floor comes up and gets relaid.
Floors and walls out of tolerance. Older construction was not built to modern tolerances, and large-format tile or slab stone exposes that immediately. Levelling screed adds cost and takes height.
Structure where you did not expect it. Always get a structural opinion before finalising a layout on an older building.
A genuine contingency is not optional here. On a building over thirty years old, make it a substantial one — you will use it, and a project with a contingency stays calm where one without it becomes a series of difficult conversations.
Local constraints
MCD and the sanctioned plan. Internal non-structural change is generally fine. The envelope, balconies, terraces and facade are not, and unauthorised additions create problems at resale.
RWA rules. Working hours, debris removal, and where material can stand. Defence Colony’s lanes are narrow and busy, and the market end is tighter still. Debris disposal genuinely needs planning — there is often nowhere legal to keep it even overnight.
Your neighbours. On a shared building your slab is someone’s ceiling. Waterproofing to bathrooms and terraces affects them. Do it properly, flood-test it, and do it once.
Access. Narrow stairs, no service lift, everything carried by hand. Measure the stair before ordering a long stone slab, a large sofa or a dining table. This is one of the most common and most avoidable problems on these projects.
Hard water. Standard across South Delhi. A softener protects fittings, shower glass and the kitchen. Plan its position at first fix.
What it costs
A good quality full renovation here covers civil work, services and joinery. Luxury specification — stone, bespoke joinery, layered lighting — sits well above that. Both exclude furniture, furnishings and design fees.
The range is wide deliberately. On an older building, how much hidden work you inherit moves the total more than any finish decision you make.
Where to spend
The hidden work. Wiring, plumbing, waterproofing. Unglamorous, and the only things you genuinely cannot redo later without undoing everything visible.
The plan. The chance to change how the floor works comes once.
Light. A new opening where permitted, a glazed partition, a lighter floor in a dark room.
Lighting layers. Two or three dimmable sources at different heights, consistent colour temperature. This is the difference between a room that works in the evening and one that only works at noon.
Working with us
Pochē Aesthetics is an architecture and interior design practice based in Greater Kailash, New Delhi, founded and led by architect Niyati Satsangi. We specialise in luxury residential and work across South Delhi on exactly this building type — fixed shell, ageing services, a plan worth rethinking — handling architecture, interiors, materials, lighting and styling as a single commission.
Defence Colony is a few minutes from the studio, which on a renovation matters more than it sounds.
If you have a floor here you are planning to rework, tell us about it. See our South Delhi guide, what renovation really involves, or the work.
