If you’re thinking of expanding your living space while maximizing light, comfort, and resale value — a glass room, veranda, or sun room might be your ideal solution. In 2025, home improvement trends across the UK show a surge in interest for garden rooms and glass-based extensions.
At Sunspaces, we’ve helped countless homeowners create stunning, functional glass rooms that feel both modern and timeless. In this guide, we’ll walk you through what you can expect in terms of cost, explore key benefits, and share smart ways to save — so you can plan confidently, stay within budget, and enjoy a beautiful new space all year round.
Why Glass Rooms Are Trending in the UK
Recent years have seen major shifts in how people use their homes — and those shifts are fueling demand for glass rooms, verandas, and sun rooms.
- Desire for more space without moving: Many UK homeowners feel their homes are too small or have underutilised space. Nearly 30% say their property feels too constraining, and a significant portion have considered extensions or garden rooms.
- Changing lifestyles: With remote and hybrid work becoming more common, people want versatile spaces — home offices, dining areas, exercise zones, or leisure spots. Glass rooms offer flexibility and can adapt over time.
- Demand for natural light and connection with nature: Biophilic design (bringing nature into living spaces) is a top trend in 2025 — and glass rooms, with large glazed walls and roofs, allow maximum daylight, views of gardens, and seamless indoor-outdoor living.
- Sustainability and energy efficiency: Modern glass rooms use improved glazing, materials, and insulation to reduce heat loss and improve energy performance, aligning with growing eco-consciousness in UK homeowners.
- Growing property value & resale appeal: Adding a well-designed glass room can significantly up the value and attractiveness of your home — buyers increasingly see such spaces as lifestyle upgrades.
Given these factors, it’s no surprise that glass rooms — from sleek modern verandas to fully enclosed sun rooms — are among the hottest home-improvement trends in the UK in 2025.
What Affects the Cost of a Glass Room / Veranda / Sun Room
Cost is often the first concern for homeowners — and for good reason. But “cost” can vary widely depending on what you want. Below are the main factors that influence price:
1. Size and Footprint
The larger the footprint, the more materials, labour, foundation work (if needed), glazing panels, and finishing touches. A compact veranda might cost much less than a full-sized glass room.
2. Type of Glass Structure
- Simple veranda canopy (roof + minimal side glazing): generally the most affordable.
- Semi-enclosed veranda / glass canopy with side panels: mid-range cost, offers more protection and usability.
- Fully enclosed glass room / sun room / garden room: highest cost, especially if insulated, with glazing walls and roof, proper foundation, heating/ventilation, etc. As highlighted recently — glass garden rooms are among the fastest growing home-improvement investments in 2025.
3. Materials & Glazing Quality
High-spec, energy-efficient glazing (e.g. low-E glass, triple glazing, insulated frames) can drive up costs, but they offer benefits in durability, comfort, energy bills, and resale value.
- Foundation / Floor / Structural Work
If the glass room requires a new base, leveling, drainage, or connection to the existing building — foundation work and structural modifications add to the cost.
5. Additional Features (Heating, Ventilation, Blinds, Lighting, Smart Integration)
If you plan to use the space year-round — for a home office or living space — you might need heating, ventilation, blinds or shades, integrated lighting, maybe even smart-home integration. All that enhances comfort — but also adds to cost.
- Labour & Permits / Building Regulations
Depending on your local council, size, and whether you’re modifying the house structure, you may need permits or compliance with building regulations — which influences cost and timeline.
Typical Cost Ranges (Indicative)
Because of these variables, cost can vary a lot. But as a rough guide:
- A simple veranda canopy or small glass veranda might be among the lower-cost options.
- A mid-range semi-enclosed veranda / veranda with side glazing generally costs more, but remains more budget-friendly than full rooms.
- A fully enclosed glass room / garden sun room — with full glazing, insulation, possibly heating, bespoke design — represents a premium investment.
At Sunspaces, we often recommend balancing size, glazing quality, and purpose (seasonal use vs. year-round use) to optimise both cost and long-term value.
Key Benefits of Choosing Glass Rooms, Verandas & Sun Rooms
Investing in a glass room — whether a veranda, garden room, or full sun room — brings multiple tangible benefits. Here’s why many UK homeowners are deciding it’s worth it:
1. Seamless Indoor-Outdoor Living
Glass rooms blur the boundary between inside and outside. Floor-to-ceiling windows, transparent roofs, and minimalist frames mean you get panoramic views of gardens, natural light, and a sense of openness — all while staying protected from the elements. Many modern verandas offer this seamless transition, making them ideal for relaxing evenings, family time, or entertaining guests.
2. Versatility & Multifunctional Use
Whether you want a peaceful home office with garden views, a dining area bathed in daylight, a yoga/meditation room, a playroom for kids, or a cosy sitting room — glass rooms are versatile. With changing lifestyle needs, such flexibility is invaluable.
3. Natural Light & Well-Being
More natural light has been linked to improved mood, productivity, and general well-being. Glass rooms maximize daylight and reduce reliance on artificial light during the day. They align with biophilic design trends — bringing nature and natural elements into daily living spaces.
- Energy Efficiency & Sustainability (if built well)
With modern glazing technologies — low-E glass, insulated frames, energy-efficient windows — glass rooms can be surprisingly efficient. They retain heat better, reduce energy loss compared to older conservatories, and help meet rising demand for sustainable, eco-conscious homes in the UK.
5. Increased Property Value & Resale Appeal
Adding a quality glass room or veranda can raise a property’s value and make it more attractive to potential buyers. In 2025, garden rooms and glass extensions remain among the top home-improvement investments UK homeowners consider before selling or renovating.
- Year-Round Usability (with proper design)
Unlike open patios or simple pergolas, modern glass rooms can be made weather-tight, insulated, and comfortable for use throughout the year — even in cold, rainy, or windy UK weather. That makes them a much more flexible addition than seasonal garden structures.
Smart Ways to Save — Get Affordable Glass Rooms Without Breaking the Bank
If cost is a concern (as it is for many), there are several strategies to enjoy the benefits of glass rooms or verandas without overspending:
1. Choose the Right Type of Structure
If you don’t need a fully enclosed year-round room, a semi-enclosed veranda or a glass veranda canopy with side panels can deliver many of the benefits (light, garden connection, extra space) at a lower cost.
2. Optimize Size & Scope
Instead of going for a large structure, start small — a compact glass veranda or modest garden room — then expand later when budget allows. This staged approach helps manage cost.
3. Use High-Efficiency Glazing & Materials Wisely
Investing in good-quality glazing and thermal insulation may cost more upfront — but over time, reduced heating costs and better energy efficiency make it worthwhile. It’s a long-term saving.
4. Prioritise What You Need — Heating, Blinds, Extras Later
If you just want extra light and space for parts of the year, skip full heating or luxury features initially. Add these later when they become essential.
5. Smart Planning & Permits
Work with a trusted provider (like Sunspaces) who can advise whether your project needs building permits or falls under permitted development rights. Minimising regulatory complications cuts both cost and delay.
6. Think Long-Term Value & Resale Benefit
Remember: a well-built glass room adds value to your home. Consider it not just as a cost, but as an investment in property value — which often pays off if you decide to sell.
What to Look for When Choosing a Glass Room or Veranda Provider
Given the growing popularity of glass rooms in the UK, many providers claim to offer the best deals. But to truly benefit, you should prioritise quality, transparency, and long-term performance. Here’s what to check:
- Use of high-quality glazing (low-E, insulated, energy-efficient) rather than thin, cheap glass.
- Durable and weather-resistant frame materials (aluminum, treated timber, etc.) that withstand UK weather year-round.
- Good insulation, proper foundations or floor solutions, especially if you want all-season usability.
- Optional extras like thermal glazing, blinds, integrated lighting, and heating capability for comfort.
- Compliance with UK building standards and regulations (especially if modifications to the main house are involved).
- Clear cost breakdowns — materials, labour, installation, finishing — so you avoid surprise expenses.
- After-sales support and warranty — important to maintain durability and add resale value.
At Sunspaces, we emphasise these points in every project. That’s why many homeowners trust us for their glass rooms and verandas — because we deliver on comfort, quality, and long-term value.

With proper glazing and insulation, convertible for occasional guests — adds flexible space.

Addressing Common Concerns & Misconceptions
Even with the popularity of glass rooms rising, some homeowners hesitate — often due to misunderstandings. Here’s what we commonly hear — and what the facts show.
“Glass rooms get too hot in summer / too cold in winter.”
With the right glazing, insulation, and ventilation/heating, a glass room can be comfortable year-round. Modern materials and designs are much better than old-school conservatories.
“They cost almost as much as a full extension.”
That depends — but by choosing a scaled-back veranda or semi-enclosed structure, you can get many benefits at a fraction of the cost. Smart planning helps manage costs effectively.
“They don’t add as much value as a brick extension.”
Many buyers today value good glass rooms, especially if they are well-built, insulated, and integrate naturally with the house and garden — making them a sought-after feature.
“Maintenance must be high — glass cleaning, heating, etc.”
High-quality glazing and materials are designed to be low-maintenance and weather-resistant. And the benefits — natural light, usability, value — generally outweigh maintenance needs.
