Whether you’re considering a small kitchen extension or dreaming of a full property transformation, this post will walk you through the process, pitfalls, and powerful benefits of extending your home with professionals who truly care.
Let’s explore how our expertise in glazing and building integrates into full-scale residential construction and what makes GL Glazing & Window Services Ltd the trusted partner for high-quality home extensions.
Why More Homeowners Are Choosing to Extend in 2025
If you’re running out of space, don’t rush to sell up and relocate. Extending your existing home is often more cost-effective than moving especially in today’s inflated housing market.
From modern kitchen-diner conversions to rear extensions with full-width bi-fold doors, families are making the most of their footprint. And the good news? You don’t have to compromise on style, space, or function.
At GL Glazing & Window Services Ltd, we help clients reimagine their homes by creating beautifully designed, energy-efficient extensions that boost property value and improve day-to-day living.
Inside the Build: How We Approach a Major Extension Project
This current project is a large rear and side extension designed to provide a spacious, open-plan living area, with floor-to-ceiling glazing and ultra-modern finishes. Our expert team will be managing everything from the groundwork to final decoration—and of course, the installation of premium windows and doors.
Here’s a breakdown of how we do it:
- Site Preparation and Demolition
We start by preparing the site and safely removing any structures or obstacles. Site access, safety, and environmental protection are all managed carefully.
- Excavation and Foundations
Precision is key here. We dig foundations to the correct depth, install a damp proof course, and prepare drainage systems all in compliance with building regs.
- Structure and Shell Build
Once the groundwork is in place, we erect the walls, steelwork, and roofing. Our expert builders work hand in hand with structural engineers to ensure long-term durability.
- Windows, Glazing, and Doors
As specialists in glazing, this is where we shine. From custom bi-fold installations to energy-efficient double glazing, we tailor each unit to the client’s vision and energy needs.
- Interior Works and Finishing Touches
Plumbing, electrics, insulation, plastering, flooring it’s all carried out by our trusted, qualified team. We also work with the client on interior finishes that align with their goals and budget.
We’re not just building rooms we’re building better lifestyles.
What to Consider Before a House Extension
Planning a house extension is exciting, but it comes with plenty to think about. Here’s what you need to know before taking the plunge:
Get the Design Right
Your extension should complement your existing home, not clash with it. We work closely with architectural partners to design layouts that maximise light, flow, and function.
Know the Rules
Planning permission may be required, depending on the size and type of extension. We help guide our clients through this and advise on permitted development rights where applicable.
Budget Smartly
The biggest mistake we see? Under-budgeting. Always factor in a contingency (10–15%) and discuss costs upfront. We offer clear, itemised quotes so clients know exactly where their money’s going.
Prioritise Energy Efficiency
With energy bills still on the rise, now’s the time to think green. Our extensions include high-performance glazing and insulation to help lower heating costs and increase comfort.
Choose the Right Builder
A home extension is a major investment. Don’t trust it to just anyone. As trusted builders for home extensions, we bring years of experience, transparent communication, and high standards to every project.
Our Specialist Edge: Glazing That Transforms Spaces
One of the most exciting features of any modern extension? The glass.
Natural light transforms spaces and our clients love the difference it makes. Whether it’s slimline aluminium frames, floor-to-ceiling picture windows, or triple-glazed skylights, the right glazing choice adds both style and substance.
We source premium products and fit them with absolute precision to prevent thermal bridging, reduce drafts, and enhance security. Because we’re not just builders we’re specialists.
Long-Term Benefits of a Home Extension
Still on the fence about extending? Here are some key benefits that make this type of investment so worthwhile:
Boost Property Value
A well-designed extension can increase your home’s value by up to 20%. It’s one of the smartest property improvements you can make.
Create Functional Family Space
Say goodbye to cramped kitchens or chaotic living rooms. A new extension can become the heart of your home, with room for everyone.
Improve Energy Efficiency
Old builds often underperform on insulation. A new extension gives you the chance to future-proof your home with sustainable solutions.
Add Flexibility
Need a home office, playroom, or gym? Extensions provide customisable space that adapts to your lifestyle.
Real Questions Homeowners Ask Before Extending
We’ve answered hundreds of client questions over the years. Here are a few of the most common ones, along with our honest answers:
How long does a typical extension take?
It depends on the size and complexity, but most single-storey extensions take 10–16 weeks from start to finish.
Do I need to move out during the build?
Not usually. We plan the work in stages and keep disruption to a minimum. You can stay comfortable while we handle the mess.
What if my extension affects a neighbour?
We handle party wall agreements and local consultations. You’ll always be in the loop and compliant with the law.
Is planning permission a nightmare?
Not with us. We manage or advise on submissions, drawings, and building regs all with minimal stress.
