Modern Conservatories and Glass Extensions
We design and build bespoke modern conservatories using the latest glass architecture. We build all types of modern conservatories. These include sleek glass boxes, minimalist winter garden rooms (or even a winter garden house), and extensions that blend naturally with your home, with windows, doors and roof all primarily glass.
At Glass House Architecture, we provide a full design-and-build service — from initial planning to full conservatory installation. Our team handles everything with precision, care, and expert craftsmanship.
Our modern offering includes:
-
Aluminium or timber-framed glass rooms
-
Glass modern conservatories with slimline profiles
-
Veranda-style garden room conservatories
-
Structural glass box extensions
As experienced conservatory builders, we focus on energy efficiency, seamless design, and adding real value to your property.
We also design frameless glass boxes for clients who want an ultra-modern finish with uninterrupted views. These builds use advanced glazing systems to remove bulky framework and create a floating glass look. Whether it's a minimalist glazed extension or a bespoke glass room, we tailor each element to your home and needs.
Traditional Conservatories and Orangeries
Our traditional conservatories and period-style orangeries bring classic English charm to your home. These elegant spaces are designed for comfort and beauty, using hardwood frames, pitched glass roofs, and refined architectural detailing.
A garden conservatory adds usable space while preserving the look and feel of your home. It’s perfect for relaxing, entertaining, or enjoying views across the garden in all seasons.
We’re proud to be one of the UK’s trusted conservatory companies, known for our blend of modern performance and traditional craftsmanship. Whether it’s a listed property or a classic villa, we’ll help you choose the best English conservatory style to suit your space.
Why Invest in a Glass Conservatory?
A well-designed conservatory is one of the best ways to enhance your property — both in value and everyday living. Whether you’re planning a stylish garden room, a double glazed side return, or a modern extension, our designs add space, comfort, and architectural elegance.
Many of our clients use their conservatory as:
-
A light-filled kitchen or dining space
-
A relaxing lounge or second living room
-
A dedicated home office or creative workspace
-
A peaceful link between house and garden
We work closely with each client to make sure their conservatory suits how they live. From planning applications to final finishing, we manage the process to be smooth and stress-free. You’ll benefit from our in-house design expertise, premium materials, and attention to detail at every stage.
Looking to increase the long-term value of your home? A bespoke conservatory offers a great return on investment, especially when built to high specifications. We use high-performance glazing, durable framing systems, and timeless architectural detailing - all tailored to your style and budget.

Our small conservatory ideas include:
-
Slimline glass walls for maximum light.
-
Contemporary aluminium or timber frames.
-
Lean-to conservatory designs, ideal for tight spots or narrow patios.
We build small conservatories to match your property style, whether modern or period. Every design includes premium materials, full thermal insulation, and the option to upgrade with heating, lighting, and outdoor connections.
Looking for inspiration? Our recent projects include small glass extensions that blend into terrace gardens, courtyard homes, and side returns, proving that you don’t need a large garden to enjoy a luxury conservatory.
Aluminium Conservatories
Lightweight, strong, and sleek - aluminium conservatories are ideal for modern living.
Aluminium is ideal if you want slim frames, a clean finish, and materials that last for decades, regardless of whether you want a large conservatory or small. It's low-maintenance and allows for larger panes of glass, which means more natural light and uninterrupted views.
We offer a range of aluminium conservatory styles, including:
Each build is fully customisable, from colour to finish, with optional features like integrated shading, solar control glazing, and smart ventilation. If you're after a crisp, modern look with minimal bulk, an aluminium conservatory is a brilliant choice, along with limitless interior design options.
Each conservatory roof can be tailored with options like solar-control glass, integrated lighting, or lantern features, offering style and year-round performance.
Our team manages everything from planning permissions to final detailing, making the process stress-free and efficient.
Garden Room Conservatories
Bring the outdoors in with a garden room conservatory.
This type of extension connects your indoor space with your garden, creating a light-filled area that works beautifully all year round. It’s perfect as a second lounge, home office, or family dining space.
At Glass House Architecture, our garden room conservatories combine structural strength with elegant glass design. You can choose traditional detailing or a more modern finish, depending on your home and taste.
All our garden room conservatories feature:
-
Thermally efficient glass for year-round comfort.
-
Fully opening doors or sliding panels to open up in summer.
-
Roof options include flat, glazed, or lantern styles.
We’ll help you create a garden space that feels like part of your home — peaceful, functional, and full of natural light.
Frequently Asked Questions
What types of conservatories do you build?
We offer a wide range of styles, including glass box conservatories, aluminium conservatories, garden room extensions, and traditional English conservatories (otherwise known as a "Victorian" or "Edwardian conservatory"). Every build is tailored to suit your home’s style and your space.
What makes a conservatory a ‘luxury’ conservatory?
A luxury conservatory stands out through its bespoke design, premium materials, and expert craftsmanship. It often features floor-to-ceiling glass, slimline frames, high thermal efficiency, and seamless integration with the rest of the home, offering both comfort and style all year round.
How much does a bespoke luxury conservatory or glass extension cost in the UK?
The cost of a bespoke luxury conservatory or glass extension can vary depending on the size, materials, and level of design customisation. We provide fully tailored quotes based on your specific needs and property layout.
Can you design a luxury conservatory to match a period property?
Yes — we specialise in luxury conservatories that complement both modern and period homes. From traditional hardwood orangeries to elegant Edwardian and Victorian designs, we ensure every detail reflects your home’s character and charm.
Are your conservatories suitable for year-round use?
Absolutely. Our luxury conservatories are built with energy-efficient glass, insulated roofing options, and underfloor heating compatibility. This ensures a comfortable living space in every season, whether it’s a warm summer evening or a cold winter day.
What is the difference between a luxury orangery and a conservatory?
A conservatory typically features more glass and a lighter structure, while a luxury orangery includes solid sections like a flat roof perimeter, lantern roof, and more masonry. Both offer elegant ways to extend your home, and we’ll help you choose the right option based on your design goals and property style.
Can you help if my garden is small or awkwardly shaped?
Yes - we design small conservatories for small gardens, including lean-to and corner layouts. Our solutions maximise space without compromising on light or comfort, all whilst remaining within permitted development guidelines.
