Frequently Asked Questions — Construction & Interior Design in Bangalore

House construction in Bangalore requires a BBMP building plan sanction (for BBMP-jurisdictional areas), or BDA/BIAPPA approval (for BDA-layout or peripheral areas). Key documents include: Khata certificate, land conversion certificate (if applicable), approved building plan, and commencement certificate. OSBS manages the complete BBMP plan sanction process on your behalf — you do not need to visit any government office. The approval process typically takes 30–90 days depending on plot size and zone.

Yes. OSBS provides fully custom residential construction services — from 2D floor plan and 3D elevation design to complete civil execution. Every project starts with your specific plot dimensions, family requirements, and budget. We do not use templates. Custom design is included in all construction packages from ₹1,950/sqft.

OSBS provides a 50-year structural warranty on all residential construction — covering the foundation, RCC columns, beams, floor slabs, and load-bearing walls from the date of handover. Any structural defect from workmanship or material failure is rectified at zero cost. This applies to all packages from Basic to Ultra Premium.

Yes. OSBS handles home renovation and additional floor construction in Bangalore. For floor additions, we begin with a certified structural engineer's load-bearing assessment of your existing foundation and columns. Retrofitting is managed if required. Renovation services include kitchen upgrades, bathroom remodeling, flooring replacement, painting, and complete home makeovers.

OSBS handles a full range of commercial construction projects in Bangalore — office buildings, retail spaces, restaurants, warehouses, PG buildings, rental apartment blocks, and mixed-use commercial properties. All projects include BBMP statutory approval management, structural engineering, and ISIcertified materials.

Commercial construction cost in Bangalore depends on: building type and occupancy (office vs warehouse vs retail vs PG), total built-up area, number of floors, structural specifications (standard RCC vs earthquake-resistant design), interior finish level, and location. OSBS provides a detailed cost estimate and BOQ before any project work begins.

Yes. OSBS has experience in multi-storey commercial construction — including G+3 and above structures — with advanced RCC structural design, seismic load considerations, and high-quality ISIcertified materials. All multi-storey projects include structural engineering drawings and BBMP approval management.

OSBS follows standard site safety protocols across all projects — including mandatory PPE (helmets, harnesses, safety shoes) for all site workers, daily safety briefings, scaffolding inspection before use, and restricted site access. A dedicated site engineer is present full-time to enforce safety compliance and report any incidents.

Yes. OSBS provides commercial renovation services including office space redesign, structural modifications (partition walls, mezzanine floors), interior remodeling, and MEP upgrades. Commercial renovation projects are scoped with a dedicated BOQ and fixed price before work begins.

OSBS provides complete home interior design services in Bangalore — modular kitchens, wardrobes, TV units, crockery units, false ceilings, living and dining room design, bedroom interiors, and full home fitouts. All interior work is executed by our in-house team with no subcontracting. Interior packages include a 10-year warranty on modular work and hardware.

Yes. OSBS creates interiors based on your preferred style — modern, contemporary, minimalist, traditional, Scandinavian, industrial, or luxury. Every design begins with a client brief and is presented as a photorealistic 3D render before any manufacturing or installation begins.

Our interior design scope covers all built-in and modular elements — kitchen cabinets, wardrobes, TV units, shelving, and false ceilings. For loose furniture and soft furnishings, our designers can provide recommendations and sourcing guidance as part of the design consultation.

OSBS completes most home interior projects within 45 days from design approval to handover. This is possible because modular components are manufactured in our facility while on-site civil and false ceiling work runs in parallel. The 45-day timeline applies to standard 2BHK and 3BHK full-home fit-outs. Larger projects (villas, 4BHK) may take 60–75 days.

Yes. Every OSBS interior project includes photorealistic 3D room-by-room renders before any work begins. You review the 3D design, request changes, and approve it — manufacturing and on-site work starts only after your written approval. The 3D design is included in all interior packages at no additional cost.

A turnkey construction project with OSBS includes everything from the first consultation to final key handover under a single contract — soil testing, architectural and structural design, BBMP plan approval, excavation, foundation, RCC structural framework, masonry, MEP services (electrical, plumbing, drainage), plastering, flooring, painting, interior fit-out (modular kitchen, wardrobes, false ceiling), and handover. One team, one price, one point of contact.

With turnkey construction, you deal with one company, one contract, and one point of contact — instead of separately hiring and coordinating an architect, structural engineer, civil contractor, electrical contractor, plumber, interior designer, and finishing crew. This eliminates coordination gaps, material substitution risks, and scope disputes between vendors. OSBS's turnkey projects also carry a 50-year structural warranty and 10-year interior warranty.

OSBS follows a 7-stage turnkey process: Stage 1 — Consultation and soil testing. Stage 2 — Architectural design and 3D elevation. Stage 3 — BBMP plan sanction and approvals. Stage 4 — Substructure (foundation and plinth). Stage 5 — Superstructure (RCC frame, masonry). Stage 6 — MEP services (concealed electrical, plumbing). Stage 7 — Finishes, interior fit-out, and key handover. Stage payments are tied to physical completion of each milestone.

Yes. All OSBS turnkey projects include a 50-year structural warranty covering the civil framework and a 10-year warranty on interior modular work and hardware. Annual maintenance checks are provided free of charge for the first 3 years after handover. Post-warranty maintenance services are also available on request.

Turnkey projects typically reduce overall cost by eliminating coordination overheads, preventing material substitutions, and avoiding the cost overruns that are common when multiple contractors are managed separately. At OSBS, turnkey projects are fixed-price — the total cost is locked in the contract BOQ before work begins, so there are no mid-project surprises.

3D planning in construction is the process of creating photorealistic, computer-generated models of your home or office before any physical work begins. It shows the complete layout — rooms, flooring, wall colours, furniture placement, ceiling design, and exterior elevation — in three dimensions. At OSBS, 3D planning is included in all construction and interior packages.

Yes. OSBS provides 3D modeling, walkthrough animations, and elevation renders for residential projects (independent houses, villas, apartments) and commercial projects (offices, retail spaces, PG buildings). Both interior and exterior 3D visualization is available.

3D design and planning is included at no additional cost in all OSBS construction packages (from ₹1,950/sqft) and all interior design packages. If you require standalone 3D design without a construction or interior contract, contact OSBS for a separate 3D planning quote based on project size and scope.

Yes — and this is the entire point of the 3D design stage. OSBS encourages full client review and multiple revision rounds before any design is finalized. Construction and manufacturing begin only after you approve the final 3D design in writing. Changes at the design stage are free; changes after approval may involve a revision fee depending on scope.

OSBS 3D renders are produced with high-fidelity visualization software and reflect actual material colours, finishes, and dimensions — typically 90–95% accurate to the final constructed or installed result. Slight variations may occur in lighting conditions and exact material texture rendering.

OSBS provides complete home renovation services in Bangalore — kitchen renovations, bathroom remodeling, flooring replacement, wall demolition and rebuilding, painting and plastering, false ceiling installation, electrical rewiring, and full home makeovers. Renovation projects are scoped with a fixedprice BOQ before work begins.

Yes. OSBS provides floor addition construction for existing residential buildings in Bangalore. The process begins with a certified structural engineer's assessment of your existing foundation's load-bearing capacity. If the existing structure requires retrofitting to support additional floors, OSBS manages this as part of the project. The new floor is constructed under the standard 50-year structural warranty.

Renovation timelines depend on scope. A kitchen or bathroom renovation typically takes 3–5 weeks. A single-floor cosmetic renovation (painting, flooring, fixtures) takes 4–8 weeks. A full home renovation with structural changes takes 3–5 months. All timelines are confirmed in the renovation contract before work begins.

OSBS stands apart in three specific, verifiable ways: (1) A 50-year structural warranty on all construction — written into the contract, covering foundation, columns, beams, and slabs. No other construction company in Bangalore we know of offers this in writing. (2) Dedicated site engineer per project — not a shared supervisor managing 5–10 sites simultaneously. (3) ISI-certified materials verified against your approved BOQ when they arrive at your site — no substitutions without your written consent. Beyond that, OSBS has completed projects for Sattva Group, Capgemini (ITPB, 56,897 sq ft), Concorde Group (627 villas), and Geown Oasis (291 villas) — organizations with rigorous vendor assessment standards.
