Additional Floor Construction in Sholinganallur

If you are planning additional floor construction in Sholinganallur, the first question is not the finish or the bedroom layout. It is whether the existing structure can take one more floor without hidden distress. We start there, because the cost of getting that wrong is far higher than the cost of the extra slab.

Sholinganallur has a mix of apartments, villas and independent houses on busy roads, and many owners are adding space instead of shifting. This page explains what we check, what approvals usually sit in the middle, how the work is sequenced, and where people tend to save in the wrong place.

What Sholinganallur changes on site

Sholinganallur is not a quiet internal-layout locality. It is a major junction with heavy apartment and villa development, traffic on the approach roads, and a steady mix of new and older buildings. That matters when you are adding a floor, because material movement, shuttering storage and concrete pour timing all need room. A site with a narrow frontage behaves very differently from a plot with open sides, even if both have the same built-up area.

Ground conditions also need a proper look before anyone talks about columns. In this belt we do not assume a foundation type from the pin on the map. We look at the soil investigation report, the existing footing size and the actual condition of the old structure. If the log shows weak or compressible layers, the design may need raft or pile support with tie beams. If the soil is firm and the existing foundation is sound, isolated or strip footings may still work. The bore test is cheap compared with retrofitting later.

Approval is another practical issue. In the Chennai Metropolitan Area, CMDA is the planning authority, and the building licence depends on the local body covering the plot. For a plot in Sholinganallur, we check the exact jurisdiction and the documents before we promise any timeline. Near airport influence zones, height clearance can also become part of the process if the site falls within that reach.

How we judge whether the old building can carry more

The structure does not care about wishful thinking. It cares about load path, material condition and the way the building has aged. For additional floor construction, we first inspect the visible signs: cracks at beam-column joints, deflection in slabs, damp patches around roof edges, rust stains, and any earlier repairs that look hurried. Then we compare that with drawings, if they exist, and with a site survey of the actual dimensions.

What we check before any design starts

We look for the simple things first. Column size, beam depth, slab span, foundation type, and whether there has already been any alteration in the ground floor. If someone has removed a wall or opened a large new door after the original completion, that changes the load path. If the roof waterproofing has failed for years, the steel inside may already have been working in a wet environment. That is not the right time to guess.

Our design is done to Indian standards, with RCC design under IS 456:2000, load consideration under IS 875, seismic checks under IS 1893:2016, and the broader planning and safety framework of NBC 2016. Chennai sits in Seismic Zone III, so the structure is designed as a building that must stay stable under real loads, not as a roof that simply happens to sit above the last floor.

1. Condition survey — one site visit, measurement, crack mapping and photo record. This usually takes a day, longer if access is tight.
2. Soil and existing structure review — we study the soil report, foundation details and any available drawings before we talk options.
3. Structural design — the engineer sizes the new load path, checks strengthening needs and prepares the RCC drawings.
4. Approval and BOQ — we fix the bill of quantities, split the work into milestones and sign the contract only after the scope is clear.
5. Execution and inspection — shuttering, reinforcement, concreting and curing are checked stage by stage by our site engineer.

What a fair design choice looks like

Most owners want one thing: add the floor without making the ground floor unsafe or unbearable to live in during work. That sounds simple, but there is a real trade-off. A lighter construction may reduce load, yet it can limit room sizes, wall positions and service runs. A more generous layout feels better, but may demand strengthening that pushes the budget up. We tell you both sides, because the cheapest option is not always the safest or the most usable.

For many homes, a clean RCC addition is the right answer. For others, especially older houses with uncertain footing or visible distress, strengthening may have to come first. That can include column jacketing, beam strengthening, slab repairs, or local foundation work. Sometimes the honest answer is no, not until the base is corrected. People dislike hearing that, but they dislike settlement cracks even more.

• Ask for the existing structural drawing or completion drawing if it exists.
• Check whether the soil test was done for the original building and whether a fresh test is needed.
• Confirm who issues the licence for your plot and whether CMDA clearance is part of the route.
• See the BOQ before you sign. If the scope is vague, the billing will be vague too.
• Ask what strengthening is included, and what is excluded, before you compare quotations.
• Confirm access for concrete mixer, steel delivery and debris removal on your street.

Rates, approvals and schedule

There is no honest way to price this work from a keyword alone. The rate changes with the condition of the existing structure, soil behaviour, number of floors, span, finish level and site access. For a standard residential building, the indicative range is ₹1,900 to ₹2,300 per sq ft; mid-premium work runs ₹2,300 to ₹2,800 per sq ft; premium work starts around ₹2,800 per sq ft and goes up with specification. The detailed BOQ is what settles the real figure before contract.

Approvals and design coordination can take as much attention as the physical work. On a clean file, we usually move through survey, design and BOQ first, then submission and execution after the paperwork is aligned. If the plot sits under a body with its own licence route, or if height clearance is triggered, the schedule extends. A rushed start on an incomplete file is where people get stuck half-way through.

How we work on an extra-floor job

We keep the technical work in-house. Our civil engineers, structural engineer and architect work with the site engineer who is on site every working day. If you cannot visit often, we send weekly photo updates on WhatsApp. The contract includes milestone-linked payment stages and a detailed BOQ before any signature, so you know what you are paying for and when.

If your house is in Sholinganallur and you are weighing an extra floor, we can start with a site visit and tell you plainly whether the existing building is a candidate for addition or a candidate for strengthening first. Call +91 97107 13838, or write to info@shalomconstruction.com. You can also see how we handle residential construction, architectural work and renovation when the job is more than a simple addition.
