Interior Design & Planning

Bespoke layout planning, photorealistic 3D renderings and millwork shop drawings that turn your architectural plans into a factory-ready package.

Interior Design & Planning

From drawing intake to CNC release

NEXA plans interiors the way they will actually be built. Your CAD or PDF plans, moodboards and FF&E tender specifications are reviewed by our engineering lead in a 48-hour preliminary feasibility audit, then developed into bespoke layout planning and photorealistic 3D renderings.

The package is deepened into millwork shop drawings with joint cross-sections, hardware codes and material codes, so your architect signs off the exact detail the factory will cut. We accept AutoCAD (.dwg), Revit (.rvt), SketchUp (.skp) and PDF; if you only have conceptual renderings or floor plans, our studio develops the complete drawing set from scratch.

  • Standard guest room drawing packages: 5-7 business days, revisions in 24-48 hours.
  • Value engineering against our Foshan supply chain database - identical visual finishes with optimised core materials.
  • Approved drawings convert directly into CNC cutting codes, holding factory assembly to the millimetre.

What the design package includes

Deliverables your architect and factory both work from

Layout Planning & Feasibility

A 48-hour preliminary feasibility audit of your floor plans, moodboards or FF&E tender specifications.

3D Photorealistic Rendering

Bespoke interior renders that lock the design intent before a single panel is cut.

Millwork Shop Drawings

Joint cross-sections, hardware codes and material codes detailed for architect sign-off.

CNC Release Package

Signed drawings feed CNC cutting codes so production matches the approved detail exactly.

Your drawing, our 4-stage engineering gate

01

Drawing Intake & Review

You share CAD/PDF plans, moodboards or FF&E tender specs. Our engineering lead runs a 48-hour preliminary feasibility audit.

02

Shop Drawing Deepening

We produce detailed millwork shop drawings with joint cross-sections, hardware codes and material codes for your architect sign-off.

03

1:1 Physical Mockup

For major hotel or multi-unit residential projects we build a 1:1 room mockup in our Foshan workshop with live 4K video inspection.

04

CNC Release & Production

Approved drawings are converted into CNC cutting codes, so factory assembly matches the signed shop drawings to the millimetre.

Design & engineering questions

Can you work directly from our preliminary sketches or Revit models?
Yes. We accept AutoCAD (.dwg), Revit (.rvt), SketchUp (.skp) and PDF formats. If you only have conceptual renderings or architectural floor plans, our engineering studio can develop complete shop drawings from scratch.
How does NEXA guarantee design fidelity during factory production?
Manufacturing lines use CNC machinery fed directly by approved shop drawing cut-lists. Prior to container stuffing we perform mandatory 100% dry-fit mockups with live high-definition video sign-off.
What is your turnaround time for a typical hotel suite drawing package?
Initial shop drawings for a standard guest room package (wardrobe, headboard, vanity, TV console) take 5 to 7 business days. Revisions are typically turned around in 24 to 48 hours.
How does Value Engineering work without compromising luxury quality?
We analyse your architectural specs against our Foshan supply chain database and suggest identical visual finishes with optimised core materials, reducing both cost and warping risk in humid climates.
