Idea Renovation is a family-owned architecture and BIM consulting studio based in Kennesaw, Georgia, founded by Alirio Rojas and Natalie Alarcón.

​

With over 20 years of combined international experience and more than 4 years delivering projects in USA, we specialize in BIM-driven architectural design, documentation, and project coordination. Our approach connects design intent with technical precision, ensuring projects are efficient, code-compliant, and build-ready.

​

Built on the values of precision, integrity, and personalized collaboration, we support clients throughout the project lifecycle—from early design and BIM strategy to multidisciplinary coordination—always aligned with local codes, sustainability goals, and construction realities.

​

Working across residential and commercial projects, renovations, and existing-condition modeling, and in collaboration with trusted engineers and consultants, we deliver high-performance BIM solutions that reduce risk, improve coordination, and translate complex requirements into clear, coordinated, and executable designs.

BIM Consulting

We provide BIM-driven consulting services that support the entire project lifecycle—from early concept to construction and close-out—ensuring clarity, coordination, and informed decision-making at every stage.

​

We develop intelligent BIM models that evolve alongside the project, serving as a centralized source of truth for design validation, documentation, and construction coordination. Our workflows are aligned with current MBIM standards, enabling seamless collaboration between architects, engineers, consultants, and contractors.

Our BIM services include:

​

  • BIM modeling and coordination from conceptual design through construction and project close-out.

  • BIM-based documentation, compliant with industry protocols and construction standards.

  • Quantity takeoffs and metric tracking, supporting accurate cost control throughout the construction process.

  • BIM-supported construction management tools, including progress tracking, control sheets, and coordination support.

  • ​

By leveraging BIM as a management and decision-making platform, we help reduce risk, minimize errors, improve coordination, and deliver build-ready, efficient, and well-coordinated projects.

Architecture

Idea Renovation is an architecture and design studio specializing in comprehensive architectural services, guiding projects from early concept and preliminary studies through detailed design and construction documentation.

​

Our architectural process is collaborative and client-centered, actively involving clients and end users at every stage of design to ensure solutions that are both functional and meaningful. We combine creative vision with technical precision to develop projects that are clear, efficient, and build-ready.

​

All our architectural projects are developed in strict compliance with local and state building codes, with a strong focus on functionality, environmental integration, and sustainable design principles. We carefully evaluate site conditions, environmental impact, and building performance to deliver projects that are accessible, efficient, and optimized for construction.

​

Through a BIM-enabled workflow, we design spaces that enhance quality of life, streamline construction processes, and translate design intent into well-coordinated, durable, and livable environments.

​

We provide a comprehensive range of renovation services, including:

  • Interior and exterior painting

  • Flooring installation

  • Full bathroom renovations

  • Full kitchen renovations

  • Accent walls and interior upgrades

  • Bedroom design and space optimization

  • Decks, front patios, and backyard design

  • Fences, exterior improvements, and repairs

​

From targeted improvements to full-scale renovations, we manage every detail to ensure quality craftsmanship, clear communication, and reliable delivery, transforming existing spaces into functional, modern, and durable environments.

Engineering

We integrate architecture and engineering through a coordinated, multidisciplinary approach that ensures technical accuracy, efficiency, and constructability at every stage of the project.

​

Working alongside a trusted team of specialized engineers and technical consultants, we provide engineering solutions that add measurable value from early structural evaluation to fully coordinated construction documentation. 

​

Our engineering services include:

  • Structural engineering, including analysis, calculations, and construction-ready plans.

  • Electrical engineering, covering power distribution, lighting design, low-voltage systems, and home automation.

  • Mechanical engineering, including HVAC systems, mechanical ventilation, and domestic gas design.

  • Communications engineering, such as data networks, voice systems, security, and access control.

  • Life safety systems, including fire detection, fire protection, and egress analysis.

​

Through a BIM-coordinated workflow, we deliver integrated engineering solutions that support compliance with codes and standards, streamline construction, and ensure systems work together efficiently within the built environment.
