Aluminium Louvred Pergola 4m x 4m — Adjustable Roof, Matt Charcoal

Sixteen square metres of covered outdoor space, and a roof you control. The 4m x 4m is the largest in the range and the one to specify when the pergola needs to define a whole area rather than sit over a table — a full lounge set with a fire pit, a hot tub surround, or the covered seating section of a restaurant terrace.

The louvres here are slightly deeper at 169mm x 38mm, spanning the wider run on 195mm x 75mm beams with 116mm square posts at each corner. Turn the louvres to dial in exactly the light you want — wide open for an evening, angled across the sun through the afternoon, or shut for shelter — and because the whole structure is corrosion-resistant, UV-stable aluminium, none of it needs treating, staining or replacing down the line. Hidden fixings throughout keep the sightlines clean at a size where a fussier frame would start to look heavy.

Standing 2,550mm high, it holds its proportions over the larger footprint and reads as architecture rather than garden furniture. Backed by a 10-year structural guarantee.
