Frequently Asked Questions

Is it possible to get a custom-designed garden annexe?
Yes, we can absolutely create a fully personalized annexe that meets your specific requirements. Whether you need a particular size, special door and window configurations, or internal layout adjustments, we can accommodate your preferences. Contact our team today to discuss your vision and explore the possibilities for your bespoke project.
How is the annexe connected to electricity and internet from my main house?
We collaborate with certified electricians who can install all necessary connections between your home and the annexe. Our team coordinates with these professionals to ensure proper setup after construction is complete. You’re also welcome to use your own trusted electrician if you prefer. Either way, we’ll work together to ensure your annexe has all the power and connectivity you need.
Can I customize the exterior finish of my annexe?
Yes, you have several options for your annexe’s exterior. You can maintain the natural wood appearance by applying a yearly coat of UV protection oil or Danish oil. Alternatively, if you prefer, you can allow the timber to weather naturally, which will develop an attractive silvery-gray patina over time. Both options are popular among our customers, and we’re happy to discuss your preferences during the design process.
Do I need to get planning permission?
Planning permission is not usually required as our buildings fall under permitted development rights. We recommend getting in touch with your local council for more information on your particular area/property.
If the height of your building is greater than our standard external height of 2.5m, then it will require planning permission, unless it is positioned at least 2.0m from any boundary (then you can go up to 3.0m). Our standard buildings are 2.5m metres in height, but for gym buildings and workshops, we recommend going up to 3.0m.
You will also require planning permission if you live in a conservation area or area of outsanding natural beauty. Please check with your local council to see if this is the case.

Do you provide drawings for planning permission purpose?
Yes, we do. We have an in-house architect who produces our drawings. We also work closely with a planning consultant who submits all our planning applications on our/your behalf.
