What Design Information Is Needed Before Ordering a Light Steel Villa? | ESS Prefab Home

Architectural Inputs That Fix Geometry

Every dimension you freeze reduces the risk of a site modification later.

• Dimensioned floor plans and elevations for each storey
• Roof plan with pitch, overhang and ridge direction
• Door and window schedule including opening sizes and swing
• Stair, balcony and canopy details that attach to the frame

Performance Inputs That Fix the Envelope

Performance requirements decide insulation, glazing and coating, which are the largest cost variables after steel.

• Design wind speed, snow load and seismic zone for the site
• Target thermal performance or energy code to be met
• Corrosion environment: coastal, industrial or inland
• Fire rating and acoustic requirements from local regulations

Site and Service Inputs

Services and access determine whether the kit can actually be installed as drawn.

• Site plan with access roads, gate width and crane standing area
• Foundation type and finished floor level
• Water, power and drainage entry points
• Local permit conditions that restrict height, footprint or appearance

Frequently Asked Questions

Do I need an architect before contacting a supplier?

Not necessarily. A dimensioned sketch is enough to start, but a firm order needs dimensioned plans and load criteria that both sides sign off.

What happens if my design changes after the order?

Changes before drawing approval are usually free to incorporate. After that, roll-formed profiles and cut panels may already be committed, so changes carry cost and delay.

Can the supplier produce drawings for me?

Most suppliers can produce erection and shop drawings from your architectural plans. Design responsibility for the building itself should stay with a qualified local professional.
