Materials Guide
Practical guidance on building materials for your UK kitchen extension — what to buy, how much you need, and what to check when it arrives on site.
Concrete Products
Ready-mix concrete grades, rebar and mesh reinforcement, formwork, spacers, and damp-proof membrane for extension foundations and slabs.
Electrical Materials
Cable, back boxes, consumer units, MCBs, RCBOs, and wiring accessories for a domestic extension — what each component does and what to check when your electrician specifies it.
Finishing Materials
Plasters, fillers, sealants, adhesives, primers, and paint for the final stages of your kitchen extension — the materials that turn a shell into a room.
Fixings
Screws, bolts, anchors, brackets, and connectors for securing structural and non-structural elements in your extension build.
Insulation
PIR boards, mineral wool, cavity batts, EPS, and insulated plasterboard for achieving building regs U-values in walls, floors, and roofs of a domestic extension.
Masonry
Blocks, bricks, sand, cement, lime, and mortar for the walls and below-DPC groundwork of a domestic extension — the raw materials your bricklayer will use every day.
Plumbing Materials
Copper pipe, pushfit fittings, soil pipe, waste traps, and stop valves — the materials your plumber will use and what to check on delivery and at building control inspections.
Roofing Materials
Tiles, membranes, lead flashing, EPDM, GRP, and battens — the materials that make your extension weathertight and what building control will inspect before they sign it off.
Sheet Materials
Plasterboard, cement board, and lining products for walls, ceilings, and wet areas in your kitchen extension — which board goes where and why it matters.
Timber
Structural timber, treated wood, sheet boards, skirting, and architrave for framing, flooring, and finishing trim in your kitchen extension.
