Project Overview
VK Home Designs is a design and construction company offering end-to-end solutions across architecture, construction and interiors.
With high-value residential projects at stake, the business needed a steady flow of relevant enquiries from homeowners considering construction and interior design services.
Growthians Marketing worked on optimising the brand’s Meta Ads and WhatsApp lead-generation funnel, focusing on audience refinement, creative testing and more efficient acquisition of customer conversations.
Objective
The objective was to improve the efficiency of WhatsApp lead generation while creating a more scalable system for attracting prospective homeowners.
The key goals were to:
- Reduce the cost of generating WhatsApp conversations.
- Refine audience targeting around homeowner intent.
- Improve creative messaging and testing.
- Increase relevant enquiry volume.
- Build a repeatable framework for scaling conversations efficiently.
Challenges Faced
The existing Meta campaigns were generating enquiries, but acquisition efficiency needed improvement.
High Cost per Conversation
The cost of initiating WhatsApp conversations needed to be reduced to make customer acquisition more efficient.
Audience Refinement
Campaign targeting needed to focus more closely on audiences relevant to residential construction and interior design services.
Limited Creative Experimentation
A more structured testing process was needed to identify which creative approaches and messages generated stronger responses.
Connecting Creative to Homeowner Intent
The messaging needed to reflect the factors that influence homeowners’ decisions, including design quality, execution, pricing and reliability.
Scaling the WhatsApp Funnel
The campaign needed a more repeatable approach to generating conversations without allowing acquisition costs to rise unnecessarily.


Strategy Implemented
WhatsApp-Focused Campaign Strategy
We structured Meta Ads campaigns around driving prospective homeowners directly into WhatsApp conversations.
Key actions included:
- Refining audiences around relevant homeowner interests and purchase intent.
- Concentrating targeting on relevant audiences within the Bengaluru market.
- Monitoring conversation volume and acquisition costs.
- Reviewing campaign performance to identify opportunities for improvement.
- Continuing optimisation as performance data became available.
Creative Strategy & Testing
The creative approach focused on giving prospective homeowners clear reasons to start a conversation.
Project-Led Creative
Showcased completed projects and actual design work to demonstrate the brand’s execution capabilities.
Trust-Focused Messaging
Highlighted factors relevant to homeowners evaluating a construction or interiors partner, including quality, design, execution and reliability.
Multiple Messaging Angles
Tested different approaches built around aspiration, pricing and design appeal to identify which messages encouraged stronger responses.
This combination of audience refinement and creative experimentation helped guide campaign decisions using observed results rather than assumptions.
Results
The optimisation process improved the reported cost of generating WhatsApp conversations across the two campaign phases.
Phase 1 — Initial Campaign Performance
1,132 messaging conversations
₹222.91 cost per conversation
₹2,52,336 campaign spend
₹10 crore reported revenue generated
Phase 2 — Further Optimisation
162 additional messaging conversations
₹88.73 cost per conversation
₹14,374 campaign spend
Acquisition Efficiency
The average cost per conversation fell from ₹222.91 in Phase 1 to ₹88.73 in Phase 2.
That represents an approximately 60% reduction in cost per conversation.
Across both phases, the reported figures totalled:
1,294 messaging conversations
₹2,66,710 in campaign spend
The improvement in cost per conversation provided a more efficient basis for generating prospective customer enquiries through WhatsApp.
Overall Impact
The engagement helped establish a more structured and cost-efficient WhatsApp lead-generation approach for VK Home Designs.
By combining audience refinement, project-led creative and continued campaign optimisation, Growthians Marketing improved the efficiency of generating customer conversations.
The reported outcomes included:
- 1,294 messaging conversations across the two phases.
- A reduction in average cost per conversation from ₹222.91 to ₹88.73.
- An approximately 60% lower cost per conversation in the second phase.
- A repeatable campaign framework for ongoing homeowner enquiry generation.
- ₹10 crore in reported revenue, as provided in the campaign results.
The campaign demonstrated how systematic testing and optimisation can improve the cost efficiency of a WhatsApp acquisition funnel.
Key Takeaways
Creative Influences Acquisition Cost
Project visuals and messaging that address homeowner priorities can help encourage relevant prospects to start a conversation.
Targeting Helps Reduce Waste
Refining audiences around relevant homeowner interests and intent helps concentrate advertising spend on more suitable prospects.
WhatsApp Campaigns Need Continuous Testing
Conversation campaigns benefit from ongoing experimentation across audiences, creative formats and messaging.
Optimisation Can Improve Efficiency
Comparing results across campaign phases helps identify opportunities to reduce acquisition costs and allocate budget more effectively.
Measure Beyond the Conversation
The cost of generating a conversation is an important metric, but lead qualification, completed projects and attributable revenue provide a fuller picture of business performance.
