What Our Customers Have To Say

Our customers are truly at the heart of everything we do, and their experiences reflect the care, dedication, and attention to detail that go into every loft conversion we deliver.

I am glad I have chosen Jon for my home renovation projects. He was fantastic listening to what we wanted for the transformation and provided a lot of examples for reference. He was very efficient laying out the plans, and mostly importantly responsive whenever I reached out.

Ben Chan 3 Weeks Ago

We had an amazing experience converting our loft with Standley Design and Build, from the initial quote to completing the job. Jon was very clear about what the quote included and very well organised. Throughout the job, communication was fantastic and any small issues sorted quickly and fairly.

Richard Edwards A Month Ago

I commissioned Jon to support the development and management of my loft conversion at the begining of this year. He was very professional and brought a lot experience and patience. He was able to project manage the work to very high standards and I would recommend him.

Martin Shiderov 2 Months Ago

We had the pleasure of using Standley Design & Build to renovate and reconfigure our bedroom (which used to be a living room). The whole process was seamless, great communication throughout and we’re so so happy with the final result. Thank you so much to Jon and the team.

We are here to help.

Home improvements can feel overwhelming and full of unknowns. Our goal is to keep things simple and transparent from day one. Browse through the most common questions below, and if you need anything else, just reach out to our team.

Yes. We offer a complete design and build solution including architectural drawings, planning support, structural work and full project delivery. You can work with us from concept to completion without needing multiple contractors.

 

You can request a quote through our online form or by booking a consultation call. We will ask for initial details about your property and requirements, then follow up with a site visit, detailed estimate and proposed timeline.

 

Not all renovations require permission. Extensions, loft conversions or major structural work may need approval, while internal refurbishments typically do not. We guide you through the process and handle all planning submissions when required.

 

Timelines vary based on the scale and complexity. For example:
• Small refurbishments: 1 to 3 weeks
• Bathrooms and kitchens: 3 to 6 weeks
• Extensions and conversions: 8 to 16 weeks
A detailed schedule is provided before work begins.

Absolutely. We provide expert guidance to help you choose styles, layouts, fixtures and finishes that suit your taste and budget. Our goal is to make your home both beautiful and practical.

 

We operate across South West London and surrounding areas. If you are unsure whether your location is included, simply contact us and we will confirm.
