About NextGen Modular Build

NextGen Modular Build installs the Leka Xi System — a modern, modular alternative to the traditional brick or block-built conservatory. We handle the supply and the install, so your conservatory is warmer, faster, and more reliable than a conventional build.

Our Story

We’re part of the NextGen Group — the authorised fabricators of the Leka composite system. We don’t just install the Leka Xi system; we manufacture the components ourselves. That means tighter quality control, faster lead times, and a team that knows every detail of the product.

What We Stand For

Properly insulated base, walls, and roof. No more cold winter, no more scorching summer.

Pre-engineered modular sections install in a fraction of the time of a traditional build.

The Leka Xi system meets UK Building Regulations. We handle the paperwork.

Adjustable screw feet — no excavation, no spoil, no garden damage.
