Introduction

Artificial Intelligence (AI) is no longer just a buzzword — it is reshaping the architecture industry. Architects are using AI to generate floor plans, optimize site layouts, render photorealistic visuals, and even manage construction projects. Whether you’re a student, professional architect, or real estate developer, these tools can save time, cost, and effort while unlocking new creative possibilities.
