Your home’s loft has the potential to be a comfortable, usable living area. All it needs is a few touches from our expert builders.
We specialise in all types of loft conversions in London, including Velux loft conversions, hip-to-gable conversions, dormer extensions, Mansard conversions, and more. We will assess your loft and roof shape to determine the best type of conversion and make it a reality through expert craftsmanship, high-end materials, and a seamless, breathtaking design.

Have you ever wished your home were larger? Our builders would be happy to grant this wish through a seamless, stunning home extension. We regularly build a wide range of extensions for clients across London, including rear, side-return, wrap-around, double-storey, and basement extensions. Let us determine the best placement for your home extension and craft a space that meets your family’s needs.

House Renovations
If your home feels outdated, no longer suits your style preferences, or has begun noticeably deteriorating, a home renovation might be just what it needs. Whether you envision a spa-like bathroom oasis, a light-filled, modern kitchen, or an open floor-plan living room, our builders will breathe life back into your space.

Our Process
We believe the home renovation and extension process is about more than just building structures. It’s also about building relationships, understanding human needs, and crafting meaningful spaces. Our passion, skill, and attention to detail are reflected through every step of our process.
- Consultation and Vision Mapping: We begin with a free on-site consultation where we walk through your space, take measurements, and discuss your goals. Whatever you envision for your space, share it with us, and we’ll advise on how we can make it a reality. At the end of the vision-mapping process, we will provide a detailed concept and quote for the project.
- Design and Architecture: Next, we bring your visual concept to our in-house design team (or your preferred architect, if you have one) to create the blueprint for your project. We can handle all permits and planning applications required by your borough.
- Structural Engineering: We ensure the structural integrity of all conversions and extensions through precise calculations and inspections. Our projects meet all building compliance regulations.
- Construction: After finalising the plans and obtaining all necessary permits, our master builders get to work on construction. We manage every layer from timber to tile and keep you updated throughout the process.
- Finishing and Sign-Off: We pour our expertise and precision into every detail of your space, from the paint and plaster to the fixtures, flooring, and finishing touches. We will seek your approval before finalising the project and leaving you to enjoy your new space.

Frequently Asked Questions
Do I need planning permission for a loft conversion in England?
You may need planning permission for a loft conversion in London, depending on your borough and the type of renovation we are performing. Rest assured, our team will take care of all permits and planning applications prior to construction.
What houses can have a loft conversion?
Many London homes are suitable for loft conversions as long as they meet a minimum height of approximately 2.2 m. We will take measurements of your loft space and examine structural elements to determine the feasibility of this renovation. We have experience with all types of loft conversions and will customise your project to suit your home and desired use of the space.
How long will a loft conversion or home extension take?
The time your project will take depends on its size and scope. Ground floor extensions might take anywhere from eight to 12 weeks, while loft conversions often require between six and 10 weeks. We will give you an estimated time frame during the consultation and keep you updated throughout the process.
Can I live in my house during a loft conversion?
Yes, it is perfectly possible to live in your house during a loft conversion in London. If you are seeking ground-floor renovations, we can phase the project schedule to allow you to continue living in the home, though this may extend the timeline. We’re happy to tailor the process to your family’s lifestyle.
