Designing beautiful Interiors & identifying activities that can adversely impact business

Updated: Dec 12, 2023



The design of interior work can be relevant for buildings used for residential, commercial, shopping malls, education institutes, hotels, hospitals, offices, etc.

Characteristics of a Robust Interior design work can be measured vis a vis:

1. Accomplishing the vision of balancing functional space between

  • Filled space in the area being designed

  • Vacant space in the area being designed

2 Accomplishing vision of Colour schemes that are optimum vis-a-vis

  • Hue (Red, Green, Blue, Purple, etc, excluding white, black, etc)

  • Value (lightness or luminosity, ie how dark or light a colour is)

  • Intensity (brightness or dullness of colour)

3 Accomplishing vision of Design style of Interiors:

  • Normal or

  • Classical (a blend of both Greek and Roman and planning perfect harmony, balance, and order)

  • Modern (monochromatic color,…..palette, clean lines

4 Accomplishing the vision of Lighting

  • Mood (Ability to create an atmosphere within an area using lighting)

  • Accent (Highlighting or focusing on objects like artwork or feature locations to create dramatic effects)

  • Task-driven (For increasing light for specific tasks in a room, eg for fine work )

  • or Natural light (light from the Sun)

5. Accomplishing vision Texture & pattern

  • Defining the physical feel of something (e.g. smooth, rough, slim, etc.)

  • Defining appearance (e.g. size, shape, density, arrangement, proportion)

Providing inputs to the Architects, including landscape/ softscape architects and MEP designers, for integration of all designs across the project


3 Building quality in the designing process Interiors using designing software:

1)Essential technical steps/activities include performing the following for developing designs.

  • ·Generating Solid, surface, and mesh modeling

  • ·3D navigation Visual styles,

  • ·Renderings,

  • ·DWG and Images references

  • ·Integration with Architecture and MEP services


Software like Pro’s modeling suite Max, AutoCAD, Autodesk Revit, Autodesk 3D’s, SketchUp Photoshop, or a similar one can be considered for developing Interior design.

2)Detailed design for walls, ceiling, flooring, furniture, fixtures, staircase, internal doors & windows, etc.

3)Detailed specifications must be generated/captured for layouts, manufacturer details, serial numbers, etc.

Software like Architectural Interior Modelling or a similar one can be considered for developing Interior design

Nine stages for developing the design of Interiors

Design activities vary considerably from company to company, but generally, there are nine stages to designing the interiors for buildings, as shown below. Whatever designing processes and software are used, designing must result in developing Robust designs by accomplishing the following:

  • Build designs that are comprehensive, accurate

  • ·Contributes to building quality in construction by incorporating national and international quality standards in BOQ/material specifications and construction processes

  • Integrates statutory and safety requirements (if applicable) in the designs and drawings

  • Optimise project costs

  • Enables efficient delivery of designs & drawings

  • Incorporates maker-checker step in each design stage through the implementation of segregation of duties concept

The nine stages are:


1. Develop interior design plans

2. Develop and design furnishing plans of the area under the scope

3. Develop reflected ceiling plans

4. Develop floor covering plans — designs, specifications, and drawings

5. Develop mechanical, electrical, and plumbing engineering plans

6. Develop design and drawings of Interior areas

7. Develop Tender documents- developing tender documents -technical design aspects

8. Estimate Costs (BOQ+ labour+ direct construction variable costs)

9. Provide handholding support

In the below-listed activities, those marked *reflect those activities which can have adverse statutory implications.


Stage 1 activities that can adversely impact business (including unethical)

  • Not obtaining or not incorporating strategic inputs (like the design of interiors to be traditional, modern, contemporary, etc vis a vis furniture, fixtures, finishing, target costs, target customers) and inspirational vision vis-à-vis each area to be designed as wall locations, reflected ceiling plans, Floor covering plans, finishes, Power and data plans) from various functions

  • Not involving all relevant functional teams in the vetting of the plans as mentioned above.

Stage 2 activities that can adversely impact business (including unethical)

  • Plans developed by untrained/unskilled professionals

  • Not involving all relevant functional teams in the vetting of the Plans

  • Inadequate Standardisation leads to higher costs

  • Proposing furniture and fixtures through limited pre-identified vendors with malice intent

Stage 3 activities that can adversely impact business (including unethical)

  • Deliberately skipping a few BOQ materials from the scope of costs

  • ·Not computing costs on 1st Principal vis-à-vis raw materials, Direct construction materials, and costs of labour/fabrication or installation, leading to underestimating or overestimating project costs.

Stage 9 activities that can adversely impact business (including unethical)

  • Interior designer/consultant not providing adequate inputs and handholding support to the project team for:

  • Development of detailed specification and quality requirements

  • Development of sample boards or samples for developing Interior designs.

  • Selection of vendors for BOQ items
