Turn Your Conventional Plans into

High-Performance ICF Designs

If you already have a set of house plans but want the superior strength, comfort, and energy efficiency of Insulated Concrete Form (ICF) construction, you don’t need to start from scratch. At Robert Klob Designs, we specialize in ICF plan conversions — transforming standard wood or steel-framed drawings into full ICF-ready construction documents that meet today’s most demanding structural and energy standards.

​

With nearly 40 years of residential design experience and over 500 ICF projects across the U.S. and internationally, Robert Klob is recognized as one of the nation’s leading ICF design specialists. Our proven process ensures your converted plans are not only structurally sound, but also practical to build, code-compliant, and optimized for cost-effective construction.

Why Convert Your Plans to ICF?

ICF walls are built using interlocking foam blocks filled with reinforced concrete, creating an exceptionally strong, quiet, and efficient building envelope. Converting your existing plans to ICF allows you to enjoy:

  • Exceptional Energy Efficiency – ICF homes can reduce heating and cooling loads by up to 50%, providing year-round comfort and significant energy savings.

  • Disaster Resistance – ICF walls can withstand hurricane-force winds, wildfires, and even tornado debris impact.

  • Superior Indoor Comfort – Quiet, airtight, and free from drafts or hot spots.

  • Lower Maintenance Costs – Concrete walls don’t rot, warp, or attract pests.

  • Sustainable Design – ICF homes use fewer resources over their lifetime and reduce environmental impact.

Whether you’re building in hurricane-prone Florida, the fire zones of California, or the freezing climates of Minnesota, ICF delivers unmatched durability and performance.

Our Proven ICF Conversion Process

Our conversion process goes far beyond simply “changing wall types.” Every project is evaluated and refined to ensure compatibility with ICF construction methods, materials, and code requirements.

  1. Plan Review & Assessment
    We start by reviewing your existing drawings — architectural, structural, and mechanical — to determine compatibility and identify potential conflicts.

  2. Wall System Integration
    All framing details are converted to appropriate ICF wall types and core thicknesses. Openings, lintels, and bearing points are adjusted for concrete and reinforcement requirements.

  3. Detail Refinement
    We update foundation connections, floor and roof interfaces, window and door bucks, and penetrations to reflect current ICF best practices.

  4. Engineering Coordination
    We work with your structural engineer (or ours) to ensure full compliance with local building codes and ICF manufacturer specifications.

  5. Energy Optimization
    We evaluate envelope performance to maximize efficiency and achieve higher HERS or energy-rating results.

  6. Final Construction Package
    You receive a fully coordinated, ready-to-build ICF construction set, along with any recommended details for installers or contractors.

ICF Systems & Compatibility

We are experienced with all major ICF block systems, including Nudura®, Fox Blocks®, Logix®, Amvic®, BuildBlock®, and others. If you already have a preferred system or supplier, we tailor your drawings to match that product’s requirements — ensuring a smooth hand-off to your builder and installer.
