Building a Brick Outdoor Kitchen: Materials, Layout, and Weatherproofing

5 February 2026 by Michael Swan 2 min read

Outdoor kitchens built from brick can handle British weather for decades. The key is specifying the right materials below the worktop line.

The outdoor kitchen trend, which started in Australia and the southern US, has arrived in Kent. With longer summers and better covered-structure designs, a brick-built cooking and dining area is a realistic addition to gardens across the South East. We have built several over the past three years, from compact barbecue stations in Tonbridge to full kitchen setups with sinks, fridges, and pizza ovens near Sevenoaks.

Material Specification

Below worktop level, we use Staffordshire Blue engineering bricks or equivalent Class B units where the structure contacts the ground. Facing bricks above DPC level match the house or complement the garden design. Worktops are typically granite, porcelain slab, or polished concrete; all three handle heat and rain well. Avoid standard kitchen laminates outdoors; they delaminate within a season.

Layout Considerations

Position the cooking area downwind of the prevailing south-westerly. Nobody wants smoke blowing into the house or dining area. Allow at least 600mm of worktop either side of the grill for preparation. If you are running water to a sink, the supply and waste pipes need to be below the frost line (roughly 750mm in Kent) or lagged and trace-heated.

Shelter Options

An open-sided oak frame or green oak pergola over the cooking area keeps rain off the grill and provides shade. We build the brick piers to support the timber structure, with stainless steel post anchors cast into the pier tops. The roof can be polycarbonate, slate, or clay tiles depending on the look you want.

Frequently Asked Questions

Dense concrete blocks are heavy (roughly 20 kg each), strong, and cheap, but have poor thermal insulation. Aircrete blocks (Thermalite, Celcon) are light (roughly 8 kg), have good thermal properties, but lower compressive strength. Each is specified for different positions in a wall.
Dense concrete blocks rated at 7 N/mm2 or higher, or engineering blocks. These resist moisture and carry the heavy loads transferred through the foundation. Aircrete blocks should never be used below DPC level.
Thermalite is a brand of aircrete block manufactured by Forterra. They are lightweight, thermally efficient, and the standard choice for the inner leaf of cavity walls on new builds and extensions in the UK.
Standard 440 x 215mm blocks at 10mm joints require approximately 10 blocks per square metre of wall face. This is the same regardless of the block type or thickness.
Blockwork is sometimes used for garden walls that will be rendered, but exposed blockwork is not visually attractive. For a visible garden wall, facing bricks are the better choice. Blockwork behind render is a practical and cost-effective option.
