NextGen Leka XI Modular Build Single-Storey Extension.
One of the most common concerns homeowners have when considering a home extension is: “Will I lose natural light?” It’s a fair question—after all, no one wants to swap sunlight for shadow. But with a NextGen modular single storey extension, the opposite is often true: you can actually increase the amount of daylight that enters your home.
Thanks to a wide range of smart designs, roofing styles, and bespoke build options, NextGen’s modular solutions are tailored to preserve—and even boost—the natural light in your living space.
Modular Doesn’t Mean Monolithic
When people hear “modular extension,” they often imagine something boxy or limited in design. But that’s far from the case with NextGen.
Every NextGen modular extension is designed around your home, your lifestyle, and your light needs. Whether you’re creating an open-plan kitchen diner, a bright playroom, or a sunlit home office, we offer a variety of wall systems, roof types, and glazing configurations to make sure your new room feels light, spacious, and comfortable.
Superior Thermal Efficiency
With energy efficiency becoming a key consideration for homeowners, the Leka XI system offers outstanding thermal performance. Designed with advanced GRP (Glass Reinforced Plastic) and insulated panels, this modular system significantly reduces heat loss, keeping your new space warmer in winter and cooler in summer. Traditional brickwork, on the other hand, often struggles to match this level of insulation without expensive upgrades.
Let the Sunshine In: Roofing That Works for You
We’re not just talking about roofing. The walls of your NextGen extension can be just as open to the outside world—or as private as you like.
1. Full-Height Glazing for Maximum Light
Want to truly embrace your garden or outdoor views? Our floor-to-ceiling glazed panels create a seamless flow between indoors and out. This style is particularly popular for homeowners who want a bright, modern look and a real feeling of connection to nature.
2. Dwarf Walls with Large Glazing Panels
If you prefer something a little more traditional, dwarf walls are a brilliant option. These combine a short solid base with large glazed upper sections, providing both privacy and sunlight.
They’re ideal for spaces like garden rooms or sunrooms where you want the warmth and brightness of the outdoors with a little more structure below.
3. Bi-Folding and Sliding Doors
Light isn’t just about windows and rooflights—it’s also about the way we transition from one space to another. Our modular extensions can include wide bi-fold or sliding glass doors, which allow natural light to travel further into your home while giving you easy access to the outdoors.
Open them up in the summer, and you’ll instantly create a bright, breezy atmosphere that feels fresh and open..
Glazed Lantern Roofs
Want to make a bold statement while filling your space with sunlight? Our lantern roof option is perfect. Raised slightly above the main roof level, this glazed feature allows daylight to pour into the heart of your extension from above.
It’s a brilliant way to create a sense of height and openness—especially in kitchen or dining areas—and works beautifully in both modern and traditional settings.
Warm Roof System with Glazing Options
For those who want a more thermally efficient solution without compromising on natural light, the NextGen Warm Roof System is a game changer.
This fully insulated roof system is designed to maintain a comfortable indoor temperature all year round, but it doesn’t stop there. With optional glazing panels or Velux-style roof windows, it can flood your room with daylight while keeping energy bills low and heat retention high.
Unlike many traditional solid roofs that block out the sun, LEKA roofs are engineered to balance light, comfort, and insulation—the perfect trio for UK homes.
Built for Light, Built for Life
Because our modular systems—like the NextGen XI Base Wall System—are constructed off-site with precision-engineered materials, we can be incredibly precise when it comes to window placement, orientation, and design.
Want to maximise morning light in the kitchen? We can design your extension to face the rising sun. Prefer soft afternoon light in your lounge? No problem. Every detail is considered with your specific home and light goals in mind.
We also take into account things like existing windows, neighbouring buildings, and garden layout—so your new extension works with your home, not against it.
Energy Efficiency Meets Everyday Comfort
A well-lit space isn’t just about looks—it’s about feeling good in your environment. That’s why all our systems are designed to be thermally efficient and condensation-free, even in colder months.
Traditional conservatories often suffer from extremes—boiling hot in summer, freezing in winter. But our modular extensions use advanced insulation materials (like GRP and high-performance boards) to create spaces that are warm, dry, and energy-efficient—without sacrificing a single ray of sunshine.
No Architect? No Problem.
Another bonus: there’s no need to hire an architect, which can save you thousands. Our expert team handles the entire design process in-house, from your initial ideas to the final finish. We work with building control and surveyors, handle regulations and paperwork, and make sure your extension not only lets in plenty of light—but also ticks every legal box.
And the best part? Planning permission often isn’t needed. Our modular builds are designed to comply with Permitted Development rights, meaning you can get started faster with fewer obstacles.
Summary: Daylight is Just the Beginning
So, will you lose any daylight with a NextGen modular single storey extension? Absolutely not. In fact, you’re more likely to gain it—along with a more comfortable, energy-efficient, and valuable living space.
With custom designs, modern roofing options, and tailored glazing choices, your new extension will be a bright, welcoming space you’ll enjoy year-round.
