Add a Bedroom Without Leaving the Home You Love
Arnold has a huge stock of two and three bedroom semis and post-war family homes, and many of them are simply one bedroom short. A growing family, a new baby, teenagers who need their own space or elderly parents moving in – moving house to fix it can cost tens of thousands in stamp duty, fees and removals. A bedroom extension solves the problem for less and adds value at the same time.
Most bedroom extensions in Arnold take one of three forms. A double storey rear or side extension gives you a bedroom upstairs and extra living space below, which is usually the best value per square metre. An extension over an existing garage uses ground you already own, so it is often the cheapest route to a fourth bedroom. A single storey addition can create a ground floor bedroom with an ensuite, ideal for accessible living.
We build all three across Arnold, Redhill, Daybrook, Woodthorpe and Killisick. We know Gedling Borough Council’s planning process well, and we design bedrooms that meet building regulations for fire escape, insulation and sound – not just four walls and a window.
Every project starts with a free survey at your home. We look at foundations, drains, roof lines and neighbouring properties, then give you a clear fixed quote so you know exactly where you stand before any work begins.
Best For
Growing families in Arnold’s three bed semis who need a fourth bedroom, homeowners adding an ensuite master suite, and anyone creating a ground floor bedroom for accessible living.
Typical Timescale
Around 8-10 weeks for an over-garage bedroom, 12-16 weeks for a double storey extension, plus 8-10 weeks for planning where it is needed.
Benefits of a Bedroom Extension in Arnold
A well built extra bedroom is one of the strongest value-adding improvements you can make to an Arnold home.
- Cheaper than moving – avoid stamp duty, agent fees and removal costs, and keep your school catchment and neighbours.
- Adds real value – moving a three bed semi in Arnold to a four bed typically adds a meaningful jump in sale price, often more than the build cost.
- Designed around your family – master suite with ensuite, kids’ rooms, guest room or a ground floor bedroom for a relative.
- Two-for-one with a double storey build – the same footprint gives you a bigger kitchen or living room downstairs as well.
- Warm and quiet by design – modern insulation and sound-resistant construction make new bedrooms more comfortable than most original rooms.
- One local team throughout – design, planning, structural work and finishing handled by builders based minutes from Arnold.

What Arnold Homeowners Say
“We were going to move to get a fourth bedroom, then got a quote for a double storey extension instead. Best decision we made. The new master bedroom with ensuite is lovely and the team kept our Arnold semi liveable throughout.”
“They built a bedroom over our garage off Front Street. Planning went through Gedling with no fuss, the brickwork matches perfectly and it was done in nine weeks. Our son finally has his own room.”
“We needed a ground floor bedroom and wet room for my mum. The team designed it all, sorted building regs and finished to a really high standard. Tidy, polite and always on time. Highly recommended in Arnold.”
Bedroom Extension FAQs – Arnold
As a guide, a bedroom over a garage in Arnold starts from around £38,000, while a double storey extension with a bedroom upstairs and living space below typically runs £75,000 to £130,000. The exact price depends on size, ground conditions and finishes, so we always confirm with a fixed quote after a free survey.
Usually yes for anything at first floor level, including over-garage and double storey extensions, which go to Gedling Borough Council. Some single storey bedroom extensions fall under permitted development. We check your Arnold property, advise on the right route and handle the whole application for you.
An over-garage bedroom typically takes 8-10 weeks on site, and a double storey extension 12-16 weeks. If planning permission is needed, allow another 8-10 weeks before work starts. We give every Arnold customer a written programme so you know what happens each week.
In most cases, yes. Moving from three bedrooms to four is one of the biggest value steps in the Arnold market, and a well built extension often adds more than it costs, especially with an ensuite. A local estate agent can give you a before-and-after valuation if you want certainty first.
Almost always. Most of the structural work happens outside your existing rooms, and we only break through near the end. Our Arnold customers usually stay at home throughout, with dust sheets, daily tidy-ups and clear notice before any disruptive stages.
