The structure
Every Probuild home is an RCC framed structure — columns, beams and slabs designed to carry the building, with the walls doing no structural work. This is the right approach for Bangalore's soil conditions and for anyone who may want to add a floor later.
We use M20 grade concrete with M-sand, and ready-mix concrete for columns, beams and slabs so that the mix ratio is controlled at the plant rather than guessed at on site. Hand-mixing is the single most common place where strength gets lost on small residential sites, and we avoid it wherever the pour allows.
Reinforcement is FE 550 grade ISI-marked TMT bar — Meenakshi, Sunvik, Indus or equivalent. Cement is Birla Super, UltraTech, Ramco or ACC. Staircases are cast as proper RCC members, not built up in masonry.
If you have a structural consultant of your own, we build to their drawings. If you don't, we bring one in and you see the design before anything is dug.
Walls and plastering
Below the plinth beam, external walls go up in 8-inch solid blocks. Above that, external and internal walls are 6-inch solid blocks, with 4-inch blocks used for the lighter internal partitions where the drawing calls for them. Solid blocks throughout — not hollow blocks — because the difference shows up in sound transfer between rooms and in how well fixtures hold in the wall years later.
Plastering follows standard practice: internal and external surfaces finished true and level, ready to take paint without the wavy shadow lines you see on rushed jobs.
The compound wall is built at 4-inch thickness up to 4 feet in height as standard, and can be raised or detailed differently if you want it to.
Flooring and tiling
Living, dining, kitchen and bedroom floors get vitrified tiles. Bathrooms, balconies, utility areas and car parking get anti-skid tiles, because a polished tile in a wet area is an accident waiting to happen.
On walls, we run glazed ceramic tiles up to 7 feet in bathrooms, a 2-foot splashback behind the kitchen counter, and 5 feet in the utility area.
Granite is used where granite belongs — staircase treads and skirting in 20mm with polished edges, and in common areas where the specification calls for it.
You choose the actual tiles. We take you to the supplier, you pick what you like within the agreed allowance, and if you fall in love with something above that allowance we tell you the difference in writing before it is ordered.
Doors and windows
Main door: engineered solid-core door with a teak finish and PU coating. It's the first thing anyone touches when they visit your home, and it's not a place to economise.
Bedroom doors: Sal wood frames with engineered wood shutters. Bathroom doors: WPC frames and shutters throughout, because wood and daily water do not get along in the long run — this is where most homes start showing damage by year five.
Windows and sliding doors are uPVC framed with glass panels. In Bangalore that matters for two reasons: dust sealing on the main roads, and the fact that uPVC doesn't need repainting every few years the way steel or timber does.
Electrical
Concealed wiring and conduits throughout, run to approved electrical drawings — meaning the switch and socket positions are agreed with you on paper before a single wall is chased, not decided by an electrician on the day.
Conduits and switch boxes are VIP, National or equivalent. Switches are Anchor, Roma or equivalent. Wiring is Anchor or Finolex. Distribution boards and MCBs are Indo Asian or equivalent. Earthing is provided as per drawing.
If you want a particular switch range, home automation, or extra points for a study or workstation, that's a conversation we'd rather have at the drawing stage than after the plastering is done.
Plumbing, sanitary and water storage
Concealed plumbing lines, water supply and drainage run to drawing. Water lines are CPVC — Ashirwad or equivalent. Sanitary lines are PVC — Supreme, Ashirwad or equivalent.
An RCC underground water sump and an overhead storage tank are included. To be precise about it: one underground sump is included as standard. If your plot needs a second sump, or you want a separate borewell sump, that is a variation we price and agree in writing rather than quietly absorb or quietly bill later.
Sanitary fittings are standard models from Jaguar, Parryware, Cera or equivalent. Upgraded fittings, designer sanitaryware, concealed cisterns and the like are excluded unless we have agreed them in writing — and plenty of our clients do upgrade here, which is completely fine as long as it is decided before we buy.
Painting and finishes
Interiors get premium emulsion — Asian Paints, Birla Opus or equivalent. Exteriors get Apex or equivalent exterior-grade paint, which is what survives a Bangalore monsoon followed by four months of hard sun. Doors, MS grills and railings are finished in enamel.
The elevation as standard is a clean masonry finish. Stone cladding, ACP, architectural grooves and channels, and feature lighting are things we're happy to build — they're just priced separately, because the range between a simple elevation and an elaborate one is enormous and we'd rather not hide it inside a single lump sum.
Fabrication and metalwork
MS window grills in 10mm rod with a bright finish, MS staircase railings at 3 feet, and a simple MS ladder for the tank room. Straightforward, and included.
Waterproofing
This is the item that decides whether you're happy with your house in year seven.
Sunken slabs in bathrooms get waterproof plastering with cinder filling. The terrace gets a weathering course with 12mm jelly coating and a surface cement finish, laid to fall so water actually leaves the roof instead of sitting on it. All waterproofing follows the project drawings and the manufacturer’s own application recommendations — including cure times, which is where most site teams cut corners because waiting looks like doing nothing.
How we handle cost, since we're not printing rates
Material and labour rates in Bangalore have moved considerably over the last two years — steel and cement in particular. Any builder publishing a fixed per-square-foot rate on a website is either quoting a stale number or planning to make it up somewhere in the specification.
What we do instead: after a site visit we issue a detailed Bill of Quantities against this specification, with the rates live on the day we quote. Payments are released against a milestone schedule tied to actual completed work — not calendar dates. Any change during the project is issued as a written variation with its cost, and it is approved by you before the work happens.
Specification last reviewed: July 2026.
