Smarter Home Extensions and Commercial Projects Across Liverpool
Looking for home extensions Liverpool? At Acero Designs, we build fast, precise steel frame extensions, garden rooms, and commercial projects across the city. It is a modern method that gives you a stronger, more accurate structure in less time, with far less disruption at home.
Traditional extensions often mean weeks of delay, deep foundations, and rising costs. Steel framing avoids much of that. Your frame is precision-made off site, then assembled quickly at your property.
Why homeowners across Liverpool choose steel frame
- Faster build times, so your home is disrupted for less time
- Strong, accurate structures that will not shift, warp, or crack
- Lower long-term maintenance than timber or brick
- Better insulation performance and energy efficiency when installed correctly
Trusted Construction Partners and Suppliers
We work alongside established suppliers, engineers, and industry partners so your materials and engineering meet the standards your build depends on.













Which Home Extension Is Right for Your Liverpool Property?
Every home and budget is different. Here are the extension types we build most often across Merseyside, each engineered in a steel frame for speed and structural accuracy.
Rear Extensions: Open up the back of your home into a bright, open-plan kitchen and dining space, with wide garden access through bi-fold or sliding doors.
Side Return Extensions: Reclaim a narrow, unused side alley to widen your kitchen or living space, ideal for Liverpool’s many terraced and semi-detached properties.
Double-Storey Extensions: Add space above and below in one build, gaining extra bedrooms or a bathroom suite. The most cost-effective way to add significant square footage.
Wrap-Around Extensions: Combine a side return and rear extension to completely reconfigure your ground floor into a large, modern living hub.
Not sure which suits your home? Talk to us about your extension, and we’ll advise honestly on the best option for your property and budget.
How We Build Your Extension, Step by Step
We keep the whole process clear and structured, so you always know what happens next.
1. Free Consultation & Site Visit: We visit your property, review your goals, and assess the structure and access.
2. Design, Quote & Planning: You get a clear, itemised quote. Once agreed, we handle the drawings, structural calculations, and building regulations details.
3. Off-Site Steel Manufacturing: Your frame is precision-made off-site while groundworks are prepared, saving time and reducing on-site mess.
4. Construction & Handover: We assemble, finish, complete inspections, and hand over your finished space.
Do You Need Planning Permission for an Extension in Liverpool?
Not always. Many single-storey rear and side extensions fall under permitted development, meaning no full planning application is needed, provided they stay within set height and depth limits (often up to 4 metres for many properties). Double-storey builds, or homes in Liverpool conservation areas such as Woolton and Aigburth, usually need formal planning permission.
Every build must also meet UK building regulations for structural safety, insulation, and fire performance. We help you understand what applies to your project and coordinate the details with Liverpool City Council building control, so the process stays stress-free.

every frame designed around your exact specification.
Common questions, answered honestly:
- Will a steel frame really save time? Yes. The frame is manufactured off-site and assembled quickly, so weather delays and slow bricklaying don’t hold up your build.
- Can I stay in my home during the work? In most cases, yes. For standard rear or side extensions, we isolate the work area to keep the rest of your home clean and usable. We’ll advise you honestly if a larger build makes this impractical.
- How do you handle cost? You get a clear, itemised quote before work starts, so there are no surprises.

Acero Designs Ltd – Steel Frame & Home Extension Specialists Liverpool 20 Google reviewsPosted on Google StephenTrustindex verifies that the original source of the review is Google. Highly recommend Acero Design for LGSF construction in the UK. Their Light Gauge Steel Frame (LGSF) system helped us reduce construction costs by around 30% compared to traditional brick-and-block building methods. Fast project delivery, excellent build quality, energy-efficient design, and a professional team from start to finish. A great choice for house extensions, garden rooms, loft conversions, and modern residential construction.Posted on Google Taylor NaifTrustindex verifies that the original source of the review is Google. Acero Design have been nothing but brilliant start to finish, the steel frame for our extension looks amazing and very secure. The communication has never dropped off. Could not recommend them enough for projects in Liverpool especially where there is nothing really like this. Thank youPosted on Google WozzaTrustindex verifies that the original source of the review is Google. We’ve been blown away by the service we have received from Acero Designs and can’t thank them enough. From the very start, communicated every step of the way, helped us with guidance on ideas and then the product arrived!! It is undoubtedly the future of building, especially for young families like us who need to have minimal disruption in both time and building works. Jamie and the team have been patient whilst we overcame some groundwork hurdles, understanding that we had delays and worked around us and our timelines. On site, the team are courteous, engaging and industrious. We were originally slightly cautious about going for a LGSF, purely because we didn’t know anybody who had built this way before. But within 10 minutes of speaking to Jamie, we felt assured it was going to be the solution for us and our double storey extension project. We weren’t wrong and are absolutely made up we partnered with them. Thank you once again Jamie and team. I couldn’t recommend them highly enough.Posted on Google Andrew ButtlerTrustindex verifies that the original source of the review is Google. I recently used Acero Design for a garden room and nursery room project at my home in Allerton, and I was absolutely delighted with the service. I found them whilst searching online for trusted home extension specialists in Liverpool, and I’m very pleased I did.
