01 Chaos

Stop asking only
what type of
building it is.

Project type gives you a label. The more useful question turns that label into design and budget priorities.

Make the question useful ↓
The question that matters
What must this building do well?

Purpose decides what deserves your money later.

Self-use, rental, luxury and commercial buildings with different spatial priorities

02 Illusion

The same β€œgood feature” can create valueβ€”or remove it.

A dramatic double-height room may transform a villa. In a rental building, the same volume may sacrifice usable area without creating enough return.

Comparison showing how a double-height volume affects self-use and rental projects differently
Self useExperience can lead.

Privacy, storage and daily comfort may justify area that produces no rental return.

RentalEfficiency must answer.

Repeated, durable and easy-to-maintain units are part of the business model.

DecisionSelf useRental
Double-height livingCan improve experienceMay reduce rentable area
Highly customised storageCan add daily valueMay be too personal
Durable easy-replace finishesUsefulOften very useful
Independent service accessHelpfulOften a strong priority

Read this as relative priorityβ€”not universal good versus bad.

03 Shift

What changes with purpose?

Do not keep these as four unstyled paragraphs. Read them as four different operating briefs.

01

Home for Yourself

Comfort, privacy, family movement, storage, natural light and long-term usefulness.

  • Live well for years
  • Personal routines matter
02

Rental / Builder Floor

Usable area, independent access, repeatability, maintenance, tenant demand and service separation.

  • Work efficiently as a product
  • Maintenance must stay simple
03

Villa / Luxury

Volume, experience, larger spaces, privacy, architectural expression and premium systems.

  • Create experience and quality
  • Spatial character can lead
04

Commercial

Circulation, flexibility, accessibility, services, user behaviour and operations.

  • Support users and operations
  • Change must be anticipated

04 System

Purpose keeps travelling through the project.

It begins as a sentence, then appears in the plan, service strategy, specification, maintenance model and budget.

Purpose is not an opening question. It is a filter used throughout the project.
  1. Purpose

    What must the building do well?

  2. Layout

    Which rooms, adjacencies and movement patterns matter?

  3. Services

    What must remain independent, accessible and maintainable?

  4. Specification

    Where should durability, experience or flexibility lead?

  5. Budget

    Which outcomes deserve protection when money becomes tight?

05 Craft

You have β‚Ή5 lakh left. What should the rental project protect first?

This is not a test of expensive versus cheap. It is a test of whether spending matches the project purpose.

  • Who is the building primarily for?
  • What must it do well every day?
  • Which outcomes deserve more area?
  • Which outcomes deserve more money?
  • Which features are impressive but not useful for this purpose?

Use both priority tokens, then review your decision.
