Most Bengaluru homeowners spend months planning their floor layout but give the exterior of their home only a few minutes of thought — often just telling their contractor "something modern" or "like that house on the corner." Then they watch construction proceed, and only when the walls are up do they realise the window proportions are wrong, the parapet looks boxy, and the facade is nothing like what they imagined.
A 3D elevation design prevents this — entirely. At ₹10,000, it's one of the highest-return investments you can make before construction begins on a home that will cost ₹40 lakhs to ₹2 crores to build.
A 3D elevation is a photorealistic three-dimensional visualisation of the exterior of your home — showing exactly how it will appear after construction, with actual materials, colours, textures, shadows, and landscaping. Unlike a 2D architectural drawing, it lets you see your home before a single brick is laid.
2D Elevation vs. 3D Elevation: What's the Difference?
Many homeowners are confused about the distinction. Both are important, but they serve different purposes:
| Feature | 2D Elevation Drawing | 3D Elevation Render |
|---|---|---|
| Format | Flat, scaled technical drawing | Photorealistic 3D image or walkthrough |
| Purpose | Required for BBMP plan sanction | For homeowner visualisation and approval |
| Shows dimensions? | Yes — precise heights, widths, openings | Not dimensioned — shows appearance only |
| Shows colours/materials? | Notes only (e.g., "cement plaster") | Actual visual with textures and colours |
| Required by BBMP? | Yes | No |
| Cost at HPB | Included with floor plan (₹10,000) | ₹10,000 additionally |
The 2D drawings are your legal document for BBMP approval. The 3D elevation is your visual contract with yourself — it's how you confirm the home you imagined is actually what's being built. We always recommend getting both together. At ₹20,000 total for floor plan + 3D elevation on a ₹60–150 lakh build, the cost-to-value ratio is exceptional.

Based on client preferences across BTM Layout, HSR Layout, JP Nagar, Jayanagar, and Electronic City, here are the most popular exterior design styles we create:
Clean lines, flat or sloped parapet, minimal ornamentation, large windows, light grey/white plaster with feature cladding panels. Aluminum composite or stone cladding accents.
Strong geometric volumes, cantilevered overhangs, mix of plaster and exposed concrete, dark accent panels, recessed window frames. Preferred for premium G+2 builds.
Traditional gable or Mangalore tile roof elements combined with modern floor layouts, traditional jali screens, warm earth tones. Strong in Jayanagar, Banashankari.
Arched openings, warm terracotta and cream finishes, decorative plaster corbels, clay tile roofing or simulated tile coping. Seen in premium plots across all areas.
Premium stone cladding (granite or sandstone), stainless steel railings, double-height entrance, sculpted boundary wall with landscape lighting. High-end self-occupancy.
The 3D Elevation Design Process at HPB
- 1Floor plan alignmentYour 3D elevation is designed to match your floor plan — window positions, doors, room heights, and staircase positions are all reflected in the 3D model. If your floor plan is not yet finalised, we'll do it simultaneously.
- 2Style brief discussionWe discuss your preferred aesthetic, reference images you like, colour preferences, material preferences (stone, glass, plaster, cladding), and any specific elements you want incorporated or avoided.
- 33D modellingOur team builds a detailed 3D model of your home's exterior based on the approved floor plan and your brief. This typically takes 4–6 working days for a standard residential home.
- 4Rendering with 2 colour optionsWe render the model with two distinct colour and material schemes — typically one lighter/neutral palette and one more dramatic or characterful option. You pick your direction.
- 5Revision and deliveryWe incorporate your feedback into a revised render. Final high-resolution images are delivered in 3–4 days. Total turnaround: 7–10 working days from brief confirmation.
Why Get 3D Elevation Before Construction?
The single most important reason: making changes after construction begins is 10–50x more expensive than making them on a screen. Consider what a change costs at different stages:
| Stage of Change | Example | Approximate Cost |
|---|---|---|
| On 3D render (before construction) | Move a window 2 feet, change parapet design | ₹0 — covered in revision |
| After floor plan, before BBMP submission | Redesign front facade layout | ₹2,000–₹5,000 (redrawing) |
| After BBMP approval, before construction | Change window size or position | ₹10,000–₹30,000 (plan revision + re-submission) |
| During construction (structural already done) | Move window on structural wall | ₹30,000–₹1,50,000+ |
| After construction (walls finished) | Break and redo window opening | ₹50,000–₹3,00,000+ |
3D Elevation Styles Popular in Each South Bengaluru Area
- BTM Layout: Modern minimalist and contemporary box are the dominant styles. Fast-paced construction market — clients here prioritise clean, durable, low-maintenance facades.
- HSR Layout: Strong preference for contemporary and premium finishes. IT professional client base means openness to modern design language. Stone cladding feature panels are very popular.
