Design Questions & Answers
We understand that designing and building a glass extension comes with many questions. With five decades of expertise, here are answers to our most commonly asked design questions.
The cost of a conservatory in the UK typically ranges from £25,000 to £60,000+, depending on size, style, glazing options, and location. A lean-to or Victorian-style conservatory usually starts around £25,000–£35,000, while larger orangeries and bespoke glass extensions can exceed £40,000. Prices vary based on materials, foundation requirements, and whether planning permission is needed.
The best conservatory company in the UK should offer quality craftsmanship, excellent customer reviews, strong guarantees, and bespoke design. Room Outside is consistently rated highly for our innovative glass extensions, use of New Generation Glass, and commitment to customer satisfaction across England, Scotland, and Wales.
In many cases, glass extensions and conservatories fall under Permitted Development rights in the UK, meaning planning permission is not required. However, rules differ in England, Scotland, Wales, and Northern Ireland, and restrictions apply for listed buildings or conservation areas. We always recommend a free planning check with our team.
Developed by Room Outside, New Generation Glass is an advanced glazing technology designed for better thermal efficiency and noise reduction. Unlike traditional conservatory glass, it helps maintain comfortable temperatures year-round—keeping spaces warm in winter and cool in summer—making it ideal for modern glass extensions in the UK climate.
Installation times vary depending on the project scope. Most standard conservatories take 6–10 weeks from groundwork to completion. Larger orangeries or complex glass extensions may require 10–14 weeks. Our project managers provide a clear timeline tailored to your property and local weather conditions.
Depending on your product choice and your location, we generally offer a 10-year structural guarantee on all our conservatories and glass extensions, alongside product-specific warranties on glazing, roofing, and materials. Our guarantees are backed by trusted UK insurers, giving you peace of mind for years to come.
Depending on your product choice and your location, we generally offer a comprehensive service which includes:
- Free home visit by one of our design experts
- Bespoke 3D visualisations showing how your extension will look
- Design drawing and specifications
- Planning permission guidance and support with applications
- Material samples including glass and frame finishes
- Comprehensive written quotation with transparent pricing
The consultation is completely free with no obligation, giving you the opportunity to explore all possibilities for your home.
Orangeries generally cost 20–40% more than traditional conservatories due to their brick-built bases, solid roofing sections, and architectural detailing. While a conservatory offers a lighter, more affordable extension, an orangery provides a more seamless blend with your existing home—ideal for those seeking a premium finish.
Room Outside stands out for our:
- Bespoke design service tailored to your home and lifestyle
- Use of New Generation Glass for year-round comfort
- Strong local reputation with projects across the UK
- Comprehensive guarantees and aftercare support
- Expertise in planning and building regulations specific to UK regions
We combine innovative glass technology with traditional craftsmanship to deliver stunning, durable extensions that add value and space to your home.
Modern glass extensions require minimal maintenance thanks to New Generation Glass technology and high-quality materials. Regular cleaning with a mild glass cleaner and occasional checks of seals and mechanisms are typically all that’s needed. Our glass extensions are designed for durability and require far less maintenance than traditional conservatories, saving you time and money in the long run.
