In a city where every square foot counts, a loft extension in London is one of the smartest ways to expand your living space without moving. Whether you’re looking to create a new bedroom, home office, or even a luxurious master suite, loft extensions allow you to unlock the unused potential of your property and add substantial value to your home.
At CREST PROJECTS, we specialise in loft extensions, renovations, and home construction projects across London. With years of experience transforming underutilised lofts into beautiful, functional rooms, we provide full-service solutions — from planning to completion — tailored to your vision and budget.
Why Invest in a Loft Extension in London?
With property prices in London on the rise and moving costs soaring, homeowners are increasingly turning to loft conversions and extensions to make the most of their existing space. Here’s why a loft extension makes perfect sense:
✅ Maximise Unused Space
Your attic holds untapped potential. A well-designed loft extension can dramatically increase your home’s usable square footage without changing its footprint.
✅ Increase Property Value
A loft extension can boost your home’s value by up to 20%, making it a sound long-term investment.
✅ Versatile Living Options
From an extra bedroom or home office to a creative studio or guest suite, your new space can serve multiple purposes.
✅ Avoid the Stress of Moving
Love your location but outgrowing your home? Extending upward means you can stay rooted while gaining more room.
Our Loft Extension Services
At CREST PROJECTS, we understand that every home is unique. That’s why we offer fully customised loft extension solutions to meet your specific needs and style preferences.
🏡 Dormer Loft Extensions
Our most popular option. This design projects vertically from a sloping roof, creating generous headspace and natural light — ideal for a large bedroom or bathroom.
🧱 Hip-to-Gable Loft Extensions
Perfect for end-of-terrace or semi-detached homes, this type replaces the sloping side roof with a vertical wall, creating more usable space.
🌤️ Velux (Rooflight) Extensions
A cost-effective way to convert your loft by adding roof windows without altering the structure. Ideal for smaller spaces, studies, or creative nooks.
🏗️ Mansard Loft Extensions
These require more structural changes but offer the largest amount of usable space. Popular in period properties, particularly in central London.
Our expert team handles every detail — from design and structural engineering to electrical and plumbing work — ensuring your extension is delivered on time and on budget.
The CREST PROJECTS 4-Step Process
We’ve streamlined the process to make your loft extension experience as smooth and stress-free as possible.
1. Consultation & Site Survey
We begin with a free, no-obligation consultation where we assess your space, discuss your goals, and offer honest advice.
2. Design & Planning Permission
Our architects will create detailed plans tailored to your home’s structure and aesthetic. We also take care of planning permission and building regulation approvals where required.
3. Construction & Project Management
With a dedicated project manager and skilled trades team, we keep the build on schedule while maintaining the highest standards of craftsmanship.
4. Final Touches & Handover
Once construction is complete, we finish every detail — from flooring and lighting to custom storage solutions — ensuring your new space is move-in ready.

Planning Permission and Permitted Development in London
Many loft extensions fall under permitted development rights, but depending on your location (especially if you’re in a conservation area or own a listed property), planning permission may be necessary.
Our team has extensive experience navigating London borough councils and can manage all paperwork and submissions on your behalf.
