Permanent panelized steel homes

Permanent steel homes built with today’s technology.

K&K's residential planning approach uses prepared steel components and project-specific field work. The home, property, design, approvals, written scope, and responsible project parties determine the delivery approach.

Factory preparation makes it practical to coordinate steel framing, openings, connections, and installation planning before field work begins. Material selection, detailing, coatings, enclosure, local design inputs, and maintenance are reviewed for the project; no material alone determines whole-home performance.

A factory provides equipment, workspace, and production organization for material preparation and component fabrication. Project timing still depends on design decisions, site information, approvals, procurement, utilities, delivery, field work, and inspections.

For permitting, these homes follow the local approval process for conventional permanent residences and fit within the standard residential permitting system. More details

Project-specific pricingPricing is developed from the home, property, location, site work, finishes, quantity, approvals, and written scope.

Written scope confirmationThe proposal identifies the work included, excluded, owner-provided, and dependent on site or authority review.

Built around project requirementsLayout, exterior design, interior finishes, building systems, and delivery scope can be upgraded beyond the planning baseline.

Location review firstHave a property in mind? Contact K&K to ask whether the location and project can be reviewed.

Floor Plans

Start with a proven plan or develop a custom design.

These floor plans are flexible starting points rather than fixed packages. They can be adapted for one home or repeated across a larger project, with room relationships, dimensions, finishes, and exterior character refined for the people and property.

This table uses pod-style temporary unit for complete, capsule-like transportable products. It is treated separately from permanent residential construction.

Swipe horizontally to compare all four building types.

Comparison	K&K steel home	Traditional home	Manufactured / mobile home	Pod-style temporary unit
Use and building status
Planning construction cost	Developed from the home, property, location, site work, finishes, quantity, approvals, and written scope	Depends on design, local labor, site conditions, finishes, approvals, and contract scope	Confirm what the unit price excludes, including land, delivery, foundation, setup, utilities, and site work	Confirm the unit, delivery, utility, site, approval, and completion scope separately
Intended use	Confirm the intended residential use, occupancy, property context, and applicable local classification for the project.	Long-term permanent residence	Residential use under the HUD manufactured-housing framework	Confirm the product specific intended use, occupancy limits, and local classification with the responsible authority.
Building category	Confirm the project-specific building and property classification with the responsible local authority.	Permanent, site-built residence	HUD Code manufactured home	Transportable temporary unit; local classification varies
Foundation / support	Foundation type and design require project-specific site information and review by the responsible professionals and authorities.	Permanent foundation engineered for the residence and site	Support or foundation system follows the home design and installation requirements	Confirm the product-specific support or foundation requirements and local treatment; do not assume a removable support is acceptable.
Approval path	Confirm the applicable state and local approval path for the specific design, site, use, and project roles.	Applicable state and local residential-building process	Federal HUD Code plus installation, zoning, and site requirements	No single national residential path; treatment depends on use and local jurisdiction
Project sequence	A project-specific sequence follows review of design, site information, approvals, procurement, utilities, delivery, field work, and inspections	Sequence depends on design, approvals, site readiness, trade availability, procurement, weather, and inspections	Confirm ordering, site preparation, foundation, delivery, setup, utility, approval, and inspection milestones	Confirm unit availability together with site, utility, delivery, approval, and inspection milestones
Financing and insurance	The lender, appraiser, and insurer review the property, classification, documents, and current project requirements	The lender, appraiser, and insurer make project-specific decisions under their current requirements	Decisions depend on classification, title, foundation, installation, certification, property, and provider requirements	Decisions depend on the product, intended use, property treatment, local classification, and provider requirements
Relocation	Confirm whether relocation is contemplated and what the design, foundation, utilities, approvals, contracts, and condition assessment would require.

This comparison is a decision checklist, not a quote, schedule, financing decision, insurance decision, or whole-building performance guarantee. Project outcomes depend on the property, location, design, assemblies, approvals, providers, written scope, and current requirements. Manufactured-home terminology follows HUD’s current description of homes built to the HUD Code and transported on a permanent chassis. “Pod-style temporary unit” is a comparison label used on this page, not a single nationally defined building category; local treatment varies.
