SUN STUDIO .London

What SUN STUDIO .London does

SUN STUDIO .London (legally TDH Ltd.) is a London-based bespoke staircase and glazing specialist that designs, fabricates, and installs custom glass, steel, and wood staircases plus related glazing products for residential and commercial clients. The company runs the entire value chain from a single integrated facility in Brentford, Middlesex: site survey, 3D design and engineering, in-house fabrication of all wood, glass, and steel components, and on-site installation by its own fitters. Materials are European-grade oak, premium steel, and toughened/laminated glass, with quality inspection at both workshop dispatch and on-site delivery; steel frame glass door systems carry fire-rated certification, and steel fixings can be powder-coated to any RAL colour.

The product portfolio is organised into two main lines. The bespoke staircase line covers floating, zig-zag, helical, spine, cantilever, and straight stringer designs. The glazing line covers balustrades, mirrors (including printed/beveled/rose-gold), wall cladding, shower enclosures, rooflights and walk-on skylights, Juliet balconies, Crittall steel-framed doors, and fire-rated steel-frame glass doors. A related sub-brand, Sun Construction (sunconstruction.london), offers associated construction and building services.

Revenue is generated on a project basis via all-inclusive fixed-price quotes prepared from architectural drawings, site pictures, or phone consultations, with no publicly disclosed pricing and no subscription or recurring revenue component. Marketing is primarily through the company's website, a YouTube channel, and Instagram, with a London showroom supporting direct sales. The 2021 disclosed figures show 134 bespoke staircases generating £3,000,000 and 140 glazing projects generating £1,250,000, totalling £4,250,000. The legal entity is privately held with no disclosed external investors, funding rounds, or M&A.
