What We Install

The Leka Xi System

A complete modular alternative to a traditional brick or block-built conservatory base and wall. Combine with a Leka tiled roof for a fully insulated, year-round room extension.

What is the Leka Xi?

The New Standard for Conservatory Extensions

The Leka Xi is a warm, sustainable alternative to a traditional block or brick-built conservatory base and wall. Built with a lightweight, structurally sound GRP frame, it eliminates thermal bridging and moisture absorption for superior insulation — and it’s installed far quicker than conventional methods.

Modular Conservatory Base

The Xi base system sits on adjustable screw feet — no concrete slab, no heavy excavation. Pre-engineered modular sections slot together on site in a fraction of the time of a traditional build.

Modular Conservatory Walls

GRP wall panels with integrated insulation replace cold, damp brick dwarf walls. The result is a thermally efficient, low-maintenance surround that looks and performs far better than the traditional alternative.

How It Works

From Base to Finished Room — Step by Step

The Leka Xi system is designed for rapid, clean installation. No heavy groundworks, no weeks of disruption — just a precision-engineered system that goes together in stages.

Base Frame

Adjustable screw feet anchor the steel base frame — no concrete foundation required. The insulated GRP panels drop in to create a fully insulated, level floor platform.

Wall Structure

The GRP wall frame rises from the base — modular sections bolt together precisely, with no wet trades, no block-laying, and no thermal cold bridges.

Glazing, Roof & Finish

Windows, doors and the Leka tiled roof system complete the structure. The result: a fully insulated, building-control-compliant room extension, ready to finish inside.
