Frequently Asked Questions

We have created a list of the most frequently asked questions to help you on your journey.

How long does it take to install a Leka Xi extension?2026-02-19T13:53:32+00:00

Unlike traditional brick-and-mortar builds that can take months, the Leka Xi systems are designed for speed. Because the components are precision-engineered and prefabricated off-site, a typical installation (including the base, walls, and roof) can be completed in weeks not months. This significantly reduces the time you spend living on a “building site.”

Will the Leka Xi System stay warm in the winter?2026-02-19T13:53:13+00:00

Yes. Unlike old-fashioned conservatories that are “too hot in summer and freezing in winter,” the Leka Xis are built more like a modern house than a sunroom. They use high-performance GRP (Glass Reinforced Plastic) and thick PIR insulation. This creates a thermal break, meaning heat stays inside during the winter and is reflected away in the summer, keeping your energy bills manageable.

I have limited access to my garden—can I still have this extension?2026-02-19T13:54:43+00:00

Absolutely. This is where the Leka Xi systems shines Traditional builds require heavy diggers for deep foundations and skips for tons of soil. The Leka Xi systems are modular and lightweight, meaning components can be carried through a standard side gate or even through the house if necessary. They usually sits on specialised ground screws or concrete pads, requiring zero heavy machinery.

How does the internal space compare to a brick extension?2026-02-19T13:55:22+00:00

You actually get more room for your money. Traditional brick walls are very thick, which eats into your internal floor area. Leka Xi walls are significantly thinner while providing better insulation than a standard cavity wall. In most cases, you gain up to 52% more internal floor space, giving you more room for that dining table or sofa you’ve been eyeing.

Will this help or hurt my property value when I sell?2026-02-19T13:55:55+00:00

Because the Leka Xi system is a permanent, high-quality structure that meets Building Regulations, it is classed as a “proper” extension rather than a temporary structure like a conservatory. When it comes time to sell, your home will be valued as having an extra usable room. We can even finish the exterior in brick-slip or render to ensure it blends seamlessly with the rest of your house.

How do I get an estimate?2024-10-15T13:53:23+00:00
