⭐ Client Testimonials ⭐
It was a pleasure to work with Rob who helped us plan our kitchen extension. He was very professional, responsive and flexible throughout the process and we would have no hesitation in using his services again.
Ben Perks
Required help from Rob on planning and design issue's, good to say he's helped and consequently have followed through with a couple other designs that were pipe dream's but Rob has brought them to life ! Highly recommended
Claire Taylor
Rob provided a great service in developing our plans for a single storey extension, which included guiding us through the planning process, developing professional drawings to submit for approval and arranging for structural designs. Throughout Rob was responsive, enthusiastic and hard working and I would recommend Trevaskis Design Solutions.
Craig Sullivan
Rob has Been everything we would look for in an architect. Great vision, pragmatic and realistic, helpful, full of advice and very efficient. He helped us balance our vision for our extension with a healthy dose of realism to allow us to make the best decision for us. It’s a shame we are only extending once, because we’d definitely use his services again.

Home Extensions in Cornwall FAQs – What You Need to Know
Do I need planning permission for a home extension in Cornwall?
In Cornwall, planning permission requirements for home extensions depend on several factors, including the type, size, and location of the proposed work. While some extensions may fall under Permitted Development Rights, allowing certain works without full planning permission, others may require a formal application. It's essential to consult with a professional to determine if your project requires planning permission.
How long does it take to complete a home extension in Cornwall?
The duration of a home extension project in Cornwall varies based on its complexity. Typically, a single-storey extension may take between 6 to 8 weeks, while a two-storey extension could extend to 12 to 16 weeks. Factors influencing the timeline include design complexity, material availability, and weather conditions.
What types of home extensions can you build in Cornwall?
We offer a wide range of home extension options in Cornwall, including single-storey rear or side extensions, two-storey additions, kitchen extensions, conservatories, and loft conversions. Each project is fully tailored to your needs, blending seamlessly with your existing home and enhancing both space and value.
Can I live in my home during the extension work?
Yes, it's often possible to remain in your home during extension work. However, it's important to discuss this with your builder to ensure that the project can be completed safely and with minimal disruption to your daily life.
What are Permitted Development Rights for home extensions in Cornwall?
Permitted Development Rights allow certain types of home extensions to be carried out without the need for full planning permission. These rights are subject to specific conditions and limitations, such as size restrictions and the nature of the property. It's crucial to verify whether your proposed extension qualifies under these rights.
What building regulations must my extension comply with?
All home extensions must adhere to building regulations, ensuring safety and structural integrity. These regulations cover aspects like foundations, structural stability, fire safety, and energy efficiency. Our team ensures that your extension complies with all relevant building regulations.
How can I ensure my extension complements my existing home?
To ensure your extension blends seamlessly with your existing home, consider factors like architectural style, materials, and colour schemes. Our design team works closely with you to create an extension that enhances your home's aesthetics and functionality.
