House Renovation Company in PECHS Karachi

PECHS and Bahadurabad share a defining characteristic that shapes every renovation here: they hold one of the largest concentrations of genuinely old housing stock in Karachi. The bungalows of PECHS Blocks 2 and 6 and the homes around Bahadurabad were built in the 1970s, 1980s, and early 1990s — which means renovation in this belt is rarely a cosmetic refresh. It is structural rehabilitation of buildings that have been standing, and quietly deteriorating, for thirty to fifty years. Naffees & Sons has renovated across this central belt for decades, and this page explains what that age really demands.

A PECHS bungalow stripped back to its frame — where an honest old-home renovation actually begins, before any finish is chosen.

Old Stock Means Structural Renovation, Not a Paint Job

The mistake homeowners make with a 40-year-old PECHS bungalow is budgeting for finishes and discovering the structure underneath them is the real project. After three to five decades, the issues we routinely find are:

Concrete carbonation and rebar corrosion in columns, beams, and slabs — the protective alkalinity of the concrete has neutralised over time and the embedded steel is rusting and expanding, cracking the cover.
Settlement cracking on the clay-heavy soils common across central Karachi, particularly where additions were built without matching foundations.
Obsolete electrical and plumbing — wiring sized for 1970s loads with no earthing discipline, and galvanised plumbing that has corroded internally to a fraction of its bore.
Failed or absent waterproofing on roofs and wet areas, after decades of monsoon cycles.

This is why a credible PECHS renovation begins with a structural assessment, not a tile selection. If the frame needs work, that work comes first — finishes laid over a compromised structure simply fail again. Our grey structure cost guide explains the structural fundamentals that this kind of deep refurbishment touches.

The Documentation Problem Unique to Old PECHS Properties

Here is the issue that delays more old-area renovations than any structural defect: the paperwork. Many PECHS and Bahadurabad properties carry decades-old leasehold or sub-lease documentation, informal partitions of inherited family property, or — very commonly — non-conforming additions built over the years without ever being recorded on an approved building plan.

This matters the moment your renovation involves a structural change requiring SBCA (Sindh Building Control Authority) approval:

SBCA assesses your application against the property's last approved building plan — and if decades of additions have made the building diverge from that plan, the application stalls until the discrepancy is resolved or regularised.
Old lease and ownership documents often need updating or reconciling before approval can proceed.
Inherited and jointly-owned properties may need ownership clarity before any approved structural work can begin.

An out-of-area contractor hits these walls mid-project and downs tools. Naffees & Sons has navigated SBCA across central Karachi for 50 years; we identify the documentation position during the survey, flag what needs regularising before demolition, and keep the approval moving rather than discovering the problem after your house is half-demolished. Purely cosmetic interior renovation, of course, does not require SBCA approval at all — we advise you exactly where your project sits on that line.

Bahadurabad's Mixed-Use Renovation Reality

Bahadurabad is not purely residential — its commercial strip means a large share of properties are mixed-use: a shop or showroom at ground level with a residence above, or apartment blocks over retail. Renovating these has its own demands:

Phased, occupied-site working so a ground-floor business keeps trading while the upper residence is renovated — dust isolation, separate access, and out-of-hours scheduling.
Short-turnaround commercial fit-outs for the shopfronts themselves, where every closed day is lost revenue.
Structural coordination between commercial and residential floors that were often altered independently over the years.

We sequence mixed-use renovations to minimise disruption to whatever is operating below or beside the work. The commercial and residential floors of these properties were frequently altered independently over the decades — a shopfront extended here, a room added above there — so part of the job is reconciling those changes into a single coherent, structurally sound building rather than treating each floor in isolation.

Why PECHS & Bahadurabad Homeowners Choose Naffees & Sons

Renovating an old home is the project most likely to spring expensive surprises — hidden corrosion, documentation gaps, additions that were never approved. The value of a 50-year company here is exactly that we have seen all of it before. Our documented project portfolio includes full institutional structural renovations delivered under government contract, which is the same structural-rehabilitation skill an old PECHS bungalow needs. We assess honestly, price the structural work into the quote rather than "discovering" it later, and navigate SBCA without passing the stress to you.

How We Assess a 40-Year-Old Frame Before Quoting

The single most valuable thing we do on an old PECHS or Bahadurabad property happens before any price is given: a structural condition assessment that turns "it looks fine" into a documented understanding of what the building actually needs. A finishes-first contractor skips this, quotes low, and then bills you for the structure as "unforeseen." We do it the other way round.

Visual and percussion survey of the frame — columns, beams, and slabs tapped and inspected for spalling, hollow cover, and active cracking that signals rebar corrosion underneath.
Crack mapping and classification — distinguishing harmless shrinkage cracks from structural settlement or shear cracks that change the scope entirely.
Cover and corrosion checks at representative points where the steel is most likely compromised, so remediation is priced on evidence, not guesswork.
Moisture and waterproofing audit of roof, parapets, and wet areas — the source of much of the hidden decay in this stock.
Services condition — a check of the existing electrical and plumbing to confirm what genuinely must be replaced versus retained.

The output is a scope you can trust and a quote that already contains the structural work, so there are no mid-project "discoveries" that double your bill.

Renovate or Rebuild: The Honest PECHS Calculation

For a 40–50-year-old bungalow, "should I renovate or rebuild?" is the most important question, and the honest answer turns on how much structural remediation the frame needs. A rough rule we apply:

Structural condition	Remediation as % of renovation budget	Usual recommendation
Sound frame, mostly cosmetic decay	Under 10%	Renovate — clear winner
Localised corrosion, repairable	10–25%	Renovate — still strong value
Widespread corrosion / settlement	25–40%	Borderline — compare against rebuild cost
Compromised frame, unsafe additions	Over 40%	Rebuild usually wins

The trap is paying renovation money for a building that needed rebuilding, or demolishing a perfectly sound frame out of caution. The structural assessment above is what lets us put your specific house on this table honestly rather than guessing. A second-floor addition shifts the maths further — an existing frame must be proven able to carry the new load before it is worth renovating around; see our second floor addition cost in Karachi guide.

What Deep Refurbishment Actually Costs to Get Right

When old-home renovation goes wrong financially, it is almost always because the structural and services layer was underpriced. The sequence that protects your budget:

Structure first — concrete repair, rebar treatment and re-passivation, crack stitching, foundation attention where settlement is active.
Full MEP replacement — complete rewiring with proper earthing and a correctly rated load, and re-plumbing with new, correctly sized runs rather than patching corroded galvanised pipe.
Comprehensive waterproofing — roof, wet areas, and parapets, because re-tiling over failed waterproofing simply fails again.
Then finishes — only once the bones are right do flooring, joinery, kitchens, and bathrooms go in.

Skipping or short-changing any of the first three is what produces a beautiful renovation that is failing again within a few years. Full structural refurbishment in this belt runs PKR 1,800–3,500 per sq ft depending on remediation content; the home renovation cost in Karachi 2026 guide breaks the tiers down room by room.

Five Mistakes PECHS & Bahadurabad Homeowners Make

Budgeting for finishes and ignoring the frame — the structure is the real project in a 40-year-old house; price it first.
Hiring on a finishes-only quote — a low number that excludes structural work is not a saving, it is a deferred bill.
Leaving documentation until demolition — old leases and unrecorded additions stall SBCA approval; resolve them before the wall comes down.
Re-tiling over failed waterproofing — the damp comes straight back; waterproofing is a structural-stage task, not a finish.
Keeping old wiring "to save money" — un-earthed 1970s wiring under a modern appliance load is a genuine safety risk, not a saving.

We design every old-home renovation specifically to avoid these — which is the difference between a refurbishment that lasts decades and one that needs doing again.

Phasing the Work So Your Family Can Stay On-Site

Not every PECHS or Bahadurabad renovation allows the household to move out for four to six months, and a good contractor plans around that rather than treating it as the owner's problem. Where the structural scope permits, we phase the work so the family keeps a usable part of the house while the rest is renovated:

Zoning the house — completing one wing or floor to a liveable state, including a working bathroom and kitchen access, before opening up the next zone.
Dust and debris isolation — sealing off active work areas with proper partitions so the lived-in part of the house stays habitable, not just notionally separate.
Sequencing the messy, unsafe stages — structural remediation, full demolition, and slab work — for periods the family can be away briefly or confined well clear of them.
Managing services continuity — keeping water, power, and a functioning bathroom available to the occupied zone throughout, with planned short interruptions rather than open-ended ones.

A full structural gut renovation is genuinely safer and faster with the house vacated, and we will say so honestly when that is the case. But for staged or partial renovations, phased occupied-site working is entirely achievable — it simply has to be designed in from the start, not improvised once the family realises they have nowhere to cook. This is the same discipline we apply to mixed-use Bahadurabad properties where a ground-floor business must keep trading throughout.

Frequently Asked Questions — Renovation in PECHS & Bahadurabad

My PECHS house is 40 years old — is it better to renovate or rebuild? It depends on the structural frame. If the columns, beams, and slabs are sound or economically repairable, renovation usually wins. If remediation would consume 25–30%+ of the renovation budget, rebuilding may be the better value. We give you an honest assessment after the structural survey.

Do I need SBCA approval to renovate in PECHS? Cosmetic interior renovation does not. Any structural change — adding a floor, altering load-bearing walls, changing the footprint — requires SBCA approval, assessed against your last approved building plan. Old additions that diverge from that plan need to be addressed first, which we handle.

My property has old lease documents and unrecorded additions — can you still renovate it? Yes. We identify the documentation position during the survey and flag anything that must be regularised before structural work. This is routine for old central-Karachi properties.

Can you renovate my Bahadurabad home while my ground-floor shop stays open? Yes. We phase mixed-use renovations with dust isolation, separate access, and out-of-hours scheduling so the business below keeps trading.

How long does a full old-home renovation take in PECHS? A full gut renovation of a typical bungalow runs 4–6 months, including structural remediation and a buffer for approvals and material lead times. Structural work adds time that a finishes-only quote hides.

Can you renovate one floor while my family lives on another? Often yes, where the structural scope allows. We zone the house, isolate dust, keep services running to the occupied floor, and sequence the unsafe stages for when you can be clear of them. A full structural gut is safer with the house vacated, and we will tell you honestly which your project is.

Why is the lowest quote usually the most expensive in the end? Because on a 40-year-old house the lowest quote almost always excludes the structural and waterproofing work the building actually needs. That work does not disappear — it reappears mid-project as an "unforeseen" extra, or a few years later as failure. An itemised quote that prices the structure up front is the cheaper path overall.
