Timber Garden Rooms FAQs

Got questions about timber garden rooms? We’ve answered the ones we hear most often.

Question 1: Do I need planning permission for a garden room in?

In most cases, no. Nestive's garden rooms are generally designed to fall within Welsh Permitted Development rights, meaning planning permission is not required. Crucially, the rules in Wales differ slightly from England. We handle all the necessary checks with your local council on your behalf to ensure full compliance before any build begins.

Question 2: What warranty and aftercare do you offer?

We stand by the quality of our craftsmanship with a 10-year structural guarantee for lasting peace of mind. Our aftercare service ensures we walk you through the final details, and we're always on hand if you have any questions once you start using your fantastic new space.

Question 3: Are your garden rooms comfortable to use during the winter?

Absolutely. Every Nestive room is fully insulated to a high residential standard (in the walls, floor, and roof). This quality build ensures your space stays wonderfully warm in winter and cool in summer, guaranteeing comfortable, year-round use regardless of the weather in South Wales.

Question 4: How much value will a high-quality garden room add to my property? Answer

A well-built, high-specification garden room from Nestive is considered a valuable asset. Local property experts agree that a quality, functional room can increase your home's saleability and potentially add between 5% and 15% to its market value, giving you a strong advantage in the local market.

Question 5: How long does it take from the initial consultation to using my new room?

The timeline depends on the design complexity. Once the design is finalised and approved, the on-site build process is designed to be as fast as possible, typically taking a few weeks, with minimal disruption to your home life. We provide a clear, detailed timeline from your first design call.

Question 6: What is the difference between your Timber and Container garden rooms?

Our Timber rooms offer a warm, natural aesthetic with maximum design flexibility. Our Container rooms are built using repurposed shipping containers, offering a fast, cost-effective, and contemporary industrial look, often suited for smaller or urban spaces.
