Desk Fabrication

Custom Control Room Desk Build Specification — L-Shaped Studio Desk

Type C — Construction Guide · Local fabrication (Damascus) · Steel + birch plywood construction

Overview

The Control Room (B311) requires a custom L-shaped desk to accommodate the SSL UF8 control surface, UF1 secondary controller, Apollo x4 audio interface, and monitor shelf for the Genelec 8030C pair. The desk is designed for the specific room dimensions (207 cm width) and integrates cable management for the studio environment.

Fabrication location: Damascus, Syria — local steel fabrication shop with welding capability. Woodworking for surface and drawers can be done at same shop or dedicated joinery.

The main wing faces the front wall (monitor wall) and holds the primary work surface and control surfaces. The return wing extends to the right, providing additional surface area for secondary equipment and paperwork.

Steel Frame

Structural Frame

Specifications

ParameterValue
Material40 × 40 mm steel square tube
Wall thickness2 mm
JointsWelded construction (MIG or TIG), ground smooth
FinishPowder-coated matte black (RAL 9005 or similar)
Leg count6 legs total (4 main wing + 2 return wing)
Floor contactAdjustable leveling feet (M10 thread) with rubber pads

Frame Assembly Notes

  • All welds must be continuous (no tack-only joints) for structural integrity
  • Grind all welds flush before powder coating
  • Frame must be square and level — check diagonals before coating
  • Add a horizontal stretcher bar between front and rear legs at 30 cm AFF for rigidity
  • Monitor shelf uprights: 2× vertical posts at left and right edges of main wing, welded to frame
Do NOT: Use bolted connections for the main frame — welded joints prevent rattles and resonances that would be picked up by sensitive microphones. Do NOT skip the leveling feet — the float floor may have minor variations.

Work Surface

Desk Top

Specifications

ParameterValue
Material25 mm birch plywood (Baltic birch, B/BB grade)
Edge treatmentWalnut edge banding (solid wood, glued and sanded flush)
FinishMatte polyurethane, 3 coats, sanded between coats (220 grit)
Front edge profileSlight roundover (3 mm radius) for comfort
MountingScrewed from below through frame cross-members (countersunk)

SSL UF8 Recess

The SSL UF8 control surface requires a recessed pocket in the desk surface so that fader tops sit flush with the desk plane. This provides ergonomic fader access without wrist strain.

Recess ParameterValue
Recess dimensions470 × 345 mm (UF8 footprint + 5 mm clearance each side)
Recess depth15 mm (half the plywood thickness)
PositionCenter of main wing, 15 cm from front edge
Precision required: The UF8 recess must be routed with a CNC router or very carefully with a template and flush-trim bit. Test-fit before finishing.

Monitor Shelf

Raised Shelf

Specifications

ParameterValue
Width160 cm (full main wing width)
Depth30 cm
Height above desk+20 cm
Material25 mm birch plywood (matching desk surface)
Support2× steel uprights welded to frame, plus rear support bracket

The monitor shelf positions the Genelec 8030C tweeters at approximately 120 cm AFF (seated ear height). The Apollo x4 sits under the shelf in the center gap, keeping Thunderbolt cable runs short. [AC]

Acoustic note: The shelf surface should be covered with 5 mm neoprene or felt to reduce early reflections from the desk surface bouncing into the monitors. [AC]

Drawer Construction

  • Box: 12 mm birch plywood, dado joints
  • Bottom: 6 mm birch plywood in dado groove
  • Slides: Ball-bearing full-extension slides (soft-close)
  • Fronts: 25 mm birch plywood matching desk surface, walnut edge banding
  • Pulls: Minimal — finger-pull routed into top edge (no protruding hardware to snag cables)

Return Wing

The return wing (90 × 60 cm) provides space for a secondary display, paperwork, keyboard/mouse (if primary is on main wing), or additional outboard gear.

Cable Management

Routing & Access

Cable Tray

FeatureSpecification
LocationUnder rear edge of main wing, full 160 cm width
MaterialPerforated steel or wire mesh basket, powder-coated black
Depth10 cm (clears cable bundles)
MountingScrewed to underside of desk frame cross-members

Cable Pass-Throughs

  • 3× rubber grommets (60 mm diameter) along rear edge of desk surface
  • 1× rubber grommet at junction of main wing and return wing
  • Grommets must be split-type (removable center) for easy cable threading
Cable discipline: Route power cables on the left side of the tray, audio/data on the right. Maintain physical separation to prevent electromagnetic interference.

Room Fit Analysis

Clearance Verification

Desk in Room B311

DimensionValueCalculation
Room width207 cmSSOT
Desk main wing width160 cmSpec
Total clearance47 cm207 − 160 = 47 cm
Clearance each side23.5 cm47 ÷ 2 = 23.5 cm (centered)

23.5 cm clearance on each side is sufficient for walking past the desk and accessing side walls for panel installation or maintenance. The return wing extends into the right-side clearance space, leaving the left side fully open as the primary access path.

Tight fit: With the return wing extending right, the right-side clearance will be reduced. Verify the return wing does not block door D2 swing or access to the sound lock. [HP]
