HSR Layout is a different kind of project from most of Bangalore. It's a mature, Building Design Architects-planned layout, which means the plots are already fixed in size mostly 30x40, 40x60, or corner sites in Sectors 1 to 7 and a lot of what we're asked to design isn't a fresh build on empty land, it's a rebuild. Many houses here are 25–30 years old, and families are now either reconstructing them for a growing household, adding floors for rental income, or converting an old family home into something that works for parents, kids, and tenants all under one roof.
As experienced residential architects in Bangalore, we solve exactly these challenges. Our architectural designer working in HSR Layout plans around what's already there, the existing structure, Building Design Architects site rules, and the parking constraints outside instead of designing as if the plot were empty.
Rebuilds, Renovations, and Sector Homes We're Regularly Asked to Design
Every home in HSR Layout has different challenges, from rebuilding aging BDA properties to designing rental-friendly homes and multi-generational residences. We create practical architectural plans that maximize your property's value, functionality, and long-term investment, while working closely with our interior designers in HSR Layout to deliver a seamless living experience from structure to interiors.
Demolition and reconstruction in HSR Layout typically cost between ₹2,000 and ₹2,800 per sq. ft., while architectural design fees usually range from ₹80,000 to ₹2.5 lakh. Many older Building Design Architects homes have compact kitchens, poor ventilation, and layouts that no longer suit modern families. We redesign your existing 30x40 or 40x60 site under current Building Design Architects regulations, improving room layouts, accessibility, parking, and natural light while giving you a realistic cost estimate before demolition begins.

Constructing an additional floor generally costs ₹2,000–₹2,800 per sq. ft. and can generate rental income of around ₹18,000–₹30,000+ per month. With strong rental demand from professionals working in Koramangala, Sarjapur Road, and Electronic City, an extra floor is a valuable investment. Before planning the extension, we assess your foundation and structural capacity, then design separate entrances, utility connections, and private access for long-term rental income.

A basement usually adds around ₹250–₹350 per sq. ft. of basement area to the construction cost, while basement planning and structural design typically cost between ₹40,000 and ₹1 lakh. Parking is limited on many HSR Layout sector roads, making basement or stilt parking a practical long-term solution. We carefully design ramp slopes, headroom, ventilation, drainage, and vehicle turning space so the parking area is safe, functional, and easy to use every day.

Multi-generational planning is generally included within the architectural design fee, with no additional planning charges for most residential projects. Many HSR Layout families need a home that comfortably accommodates parents, children, and sometimes rental tenants. We design ground-floor bedrooms for elderly family members, provide attached bathrooms, create private access where required, and plan flexible living spaces that support changing family needs without increasing the overall construction budget.

Why a Good Architect Matters More in HSR Layout
Because most plots here already have a structure standing on them, mistakes are more expensive to walk back, you're not just wasting material, you're wasting a demolition too. And because HSR sites carry high resale value, a design that gets the fundamentals wrong costs you long after the family has moved in.
01
Prevents Costly Demolition Mistakes
Once a wall comes down, there's no undoing it. We finalise the layout on paper first so nothing gets torn out twice.
02
Checks What Your Old Foundation Can Actually Take
Adding a floor onto a decades-old structure isn't automatic. We verify the existing foundation and structure before promising anything on paper.
03
Solves Parking Instead of Ignoring It
A lot of rebuilds skip proper parking planning and regret it within a year. We design basement or stilt parking that's genuinely easy to use, not a tight squeeze.
04
Protected High Resale Value
HSR plots already command a premium. A well-planned rebuild protects and grows that value; a rushed one can actually pull it down.
05
Designs for Every Generation in the House
Getting ground-floor access, room placement, and privacy right for parents, family, and tenants together avoids friction that's hard to fix after the house is built.
From First Site Visit to a Home Ready to Rebuild
01
We Assess What's Already There
We visit your existing site, check the structure's condition, the foundation's capacity, and how the current layout is failing you.
02
We Plan the New Layout Around Your Household
The first concept accounts for parents, your own family, and any rental floor, laid out so nobody's privacy gets compromised by proximity.
03
We Finalize Structural and Material Details
Once the layout is set, we confirm exact measurements, structural specifications, and materials.
04
We Prepare Your BDA Approval Documents
We put together the drawings your engineer or contractor will need for Building Design Architects approval.
05
We Stay On Through Construction
We check in through the build to make sure what's coming up on site actually matches the plan, especially during the structural stages that are hardest to correct later.
