About JNR Building
Meet the Director, Julian
“I started in the construction industry as a bricklayer’s labourer, which, in hindsight, was the best way to learn the trade. With years of experience, I founded JNR Building. We pride ourselves on a close-knit team of trusted tradespeople. From smaller renovations to complete new builds, we’ve got it covered. I’ve continued to expand my skills and now hold BBA certification for fibreglass roofs. With public liability insurance, you can have peace of mind. We’ve been serving Norfolk for over a decade, and we’re here to bring your building dreams to life.”

You may not need planning permission if your extension falls within permitted development rights — for example, smaller rear extensions that meet specific size and height criteria.
However, every project is different. We can advise you from the outset and support any planning applications if needed. You can also explore the Planning Portal’s guidance on home extensions for more details.
Costs vary depending on size, materials, and complexity, but as a rough guide:
Single-storey extensions: £1,500–£2,500 per m²

A renovation updates or restores your existing home — like modernising a kitchen or updating an old bathroom. A conversion changes the use of a space, for example turning a loft into a bedroom or a garage into a living room.
We specialise in both, whether you’re improving a period home or adding usable space to a modern one.
Yes — a well-designed extension can significantly increase your home’s market value. A larger kitchen-diner, extra bedroom, or second bathroom are all desirable features for future buyers. According to property experts, an extension can boost value by up to 20%, depending on location and quality of finish.
