What is 3D Elevation Design?
Why Bengaluru Homeowners
Need It Before Construction

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.

📌 What is 3D Elevation Design?

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:

Feature2D Elevation Drawing3D Elevation Render
FormatFlat, scaled technical drawingPhotorealistic 3D image or walkthrough
PurposeRequired for BBMP plan sanctionFor homeowner visualisation and approval
Shows dimensions?Yes — precise heights, widths, openingsNot dimensioned — shows appearance only
Shows colours/materials?Notes only (e.g., "cement plaster")Actual visual with textures and colours
Required by BBMP?YesNo
Cost at HPBIncluded with floor plan (₹10,000)₹10,000 additionally
💡 Why 90% of Our Clients Get Both

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.

The 3D Elevation Design Process at HPB

  1. 1
    Floor plan alignment
    Your 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.
  2. 2
    Style brief discussion
    We 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.
  3. 3
    3D modelling
    Our 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.
  4. 4
    Rendering with 2 colour options
    We 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.
  5. 5
    Revision and delivery
    We 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 ChangeExampleApproximate Cost
On 3D render (before construction)Move a window 2 feet, change parapet design₹0 — covered in revision
After floor plan, before BBMP submissionRedesign front facade layout₹2,000–₹5,000 (redrawing)
After BBMP approval, before constructionChange 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+

Frequently Asked Questions
A 3D elevation is a photorealistic three-dimensional visualisation of your home's exterior — showing the actual appearance with materials, colours, textures, shadows, and landscaping. Unlike a flat 2D drawing, it lets you see your home before construction begins, so you can approve or change the design while it's still just a digital model.
3D elevation design costs ₹10,000 at Home Planners and Builders for a standard residential home — including front, side, and rear elevation renders, two colour scheme options, and up to 2 revisions. Many Bengaluru architects charge ₹15,000–₹40,000 for equivalent work. Our flat ₹10,000 rate makes quality 3D design accessible to all homeowners.
No — BBMP requires 2D architectural drawings, not 3D renders. However, 3D elevation is strongly recommended because it helps you finalise your exterior design before construction begins, preventing expensive changes during building. It's a design tool for your own benefit, not a regulatory requirement.
A 2D elevation is a scaled technical drawing showing exact dimensions, heights, and material notations — required for BBMP plan sanction. A 3D elevation is a photorealistic image showing how the building will actually look with real colours, materials, lighting, and shadows — for homeowner visualisation. Both are useful; we produce both at HPB.
