Overcoming Real Roadblocks

3 Major Problems & How We Solved Them

1

Bulky Dark Staircase Blocking All Daylight

The Problem

A massive 1990s wooden stair block blocked sunlight from reaching the lower ground living floor.

Our Simple Solution

Replaced it with a lightweight cantilevered steel-spine floating stair with natural oak steps and clear glass railings, flooding the hallway with vertical sunlight.

2

Underused, Hot Roof Terrace

The Problem

The upper terrace was scorching hot during afternoons and unusable during rains.

Our Simple Solution

Erected an architectural aluminum pergola with UV-tinted glass and misting fans, creating an all-weather evening lounge.

3

Separate Living Preferences Across 3 Generations

The Problem

Grandparents needed traditional quiet spaces, while younger generation wanted modern entertaining.

Our Simple Solution

Zoned the ground floor for quiet family gatherings, and designed the upper floor as a lively entertainment and terrace zone.

What We Did: Step-by-Step Execution

  • Engineered structural cantilevered floating staircase with tested load capacity of 600 kg.
  • Built an all-weather terrace pergola with artificial turf and weatherproof outdoor furniture.
