The way we design and extend our homes is changing—and fast. In 2025, one of the biggest trends reshaping home improvement is the modular orangery extension. Combining the elegance of traditional orangeries with the speed, sustainability, and precision of modular construction, it’s quickly becoming the go-to solution for stylish, high-performance living space.

If you’re planning a home extension that adds value, light, and year-round usability—this is what you need to know.

What Is a Modular Orangery?

A modular orangery is a factory-manufactured extension, delivered to site in ready-to-assemble components. Unlike traditional builds, which are constructed entirely on-site over several weeks, modular systems are pre-engineered off-site to exact specifications and assembled in just days.

Think of it as a pre-designed orangery with:

• Brick or panelled walls

• A flat or lantern-style roof

• Energy-efficient glass sections

• Customisable interior layouts

Brick or Panelled Walls: Why Vergolus Chooses Brick Slip Cladding

When it comes to building extensions, choosing between traditional brickwork and modern panelled systems is a key decision that affects not just aesthetics but also speed, cost, and long-term performance.

Traditional bricks have long been admired for their durability and timeless appeal. However, they come with challenges—longer build times, heavier load requirements, and labour-intensive installation. Bricklaying is weather-dependent, which can cause delays and increase costs. It also limits flexibility in design and requires deeper foundations due to the structural weight.

That’s why Vergolus takes a smarter approach. We use brick slip cladding, a high-performance system that offers the visual beauty of real brick without the downsides. These thin slices of genuine brick are mounted onto our steel-framed modular panels, providing a faster and more efficient alternative.

Benefits of brick slip cladding include:

• Speed of Installation: Because they’re pre-mounted onto panels, installation is significantly faster.

• Lightweight Structure: Reduces pressure on foundations and allows for modular flexibility.

• Pre-Approved and Compliant: Fully meets UK Building Regulations and fits seamlessly into pre-approved building systems.

• Aesthetic Versatility: With over 26 real brick styles, we match your home’s exterior perfectly.

By combining modern engineering with timeless style, Vergolus ensures your modular extension is not only quicker to build but beautifully integrated into your existing property — with none of the compromises.

Key Benefits of a Modular Orangery Extension

Faster Build Times

Modular orangeries can be installed in as little as 1–2 weeks, drastically reducing disruption and speeding up your renovation schedule.

Predictable Costs

Factory-built modules mean fewer unexpected delays or cost overruns. You know what you’re getting—and what you’re paying.

Superior Energy Efficiency

Modular systems are typically built with the latest insulation materials and precision-fitted glazing, meeting (or exceeding) Part L building regulations.

Customisable Design Options

From bifold doors to roof lanterns and interior finishes, you can still personalise your modular orangery to reflect your home’s style.

Low Waste & Eco-Friendly

Because everything is measured and cut in a controlled factory setting, modular builds generate far less on-site waste—and are often made with sustainable materials.

Feature	Traditional Orangery	Modular Orangery
Build time	6–10 weeks	1–2 weeks
Cost predictability	Variable	High
Customisation	High	Medium–High
Site disruption	Major	Minimal
Energy efficiency	Depends on build quality	Consistently high
Planning requirements	Similar (check with your LPA)	Similar (some come under PD rights)

Who Should Consider a Modular Orangery?

• Homeowners looking for a fast, low-stress extension

• Eco-conscious renovators

• Those wanting to maximise space with minimal disruption

• People living in high-density or tight-access areas (where on-site construction is tricky)

Modular systems are also great for those on a deadline—whether you’re preparing for a new baby, launching a home business, or upgrading in time for summer.

Custom Design Features to Expect

Even with modular construction, you’re not locked into a boring box. Today’s modular orangery designs often include:

• Aluminium or timber-look frames

• Slimline bifold or sliding doors

• Brick or composite external walls

• Roof lanterns with solar control glass

• Integrated lighting and heating options

• Skylights and smart glass options

Are Modular Orangeries the Future?

Absolutely. As we move towards greener, faster, and more tech-driven building practices, modular extensions offer homeowners a way to stay ahead of the curve—without compromising on aesthetics or quality.

Expect to see more homes using modular orangery pods as self-contained living rooms, home offices, garden studios, or even annexes for multigenerational living.

Frequently Asked Questions: Modular Orangery Extension

1. What is a modular orangery extension?

A modular orangery is a pre-fabricated home extension built off-site and assembled on-site. It combines traditional orangery aesthetics with modern construction efficiency.

2. How long does a modular orangery take to install?

Most modular orangeries can be installed in 1–2 weeks, significantly faster than traditional builds that may take 6–10 weeks.

3. Are modular orangeries energy efficient?

Yes. Modular systems use precision-cut components, high-performance insulation, and energy-efficient glazing, often exceeding building regulations.

4. Do I need planning permission for a modular orangery?

It depends on the size and location. Some modular orangeries fall under permitted development rights, but you should always check with your local planning authority.

5. Can I customise a modular orangery?

Yes. You can choose features such as bifold doors, roof lanterns, materials, and interior finishes to suit your home and style preferences.

6. Are modular extensions more expensive than traditional builds?

Not necessarily. While upfront costs may be similar, fewer labour hours, lower waste, and faster build time often make modular options more cost-efficient overall.

7. Are modular orangeries permanent structures?

Yes. Despite being factory-built, modular orangeries are fully integrated and designed as permanent, high-quality additions to your home.

8. What kind of foundations do modular orangeries need?

Most require a concrete base or screw pile foundations, which are often installed just prior to delivery and assembly.

9. Can modular orangeries be used all year round?

Absolutely. With proper insulation, heating, and glazing, modular orangeries are designed for year-round comfort and use.

10. Do modular orangeries add value to a home?

Yes. A well-designed modular orangery can increase your home’s resale value while also enhancing its usable living space.
