HOW DOES IT ALL WORK?

Designing your dream garden room has never been easier. At Spikeows, we keep the process simple, stress-free, and tailored to you. You don’t need to worry about layouts upfront—our Building Configurator is there to give you a clear idea of what we offer and the pricing attached.

When you’re ready, we recommend speaking to an expert before placing your order. You can upload your own sketch or ideas, or after placing your deposit, our team will work closely with you to create a custom layout diagram that fits your exact vision.

With transparent pricing, expert advice, and a team dedicated to quality, Spikeows ensures your garden room is designed around you—let’s create something extraordinary together.

At Spikeows, we primarily work in feet. Enter a value in meters below to convert it to feet for use in the building configurator:

Feet:

Spikeows garden rooms come with standard depths up to 12ft. For depths 13ft and above, these are classified as extra depth due to the increased roof span, requiring upgraded roof timbers for enhanced strength and durability. This ensures your building remains structurally sound and long-lasting, even at larger sizes. As a result, buildings with extra depth are priced higher to reflect these essential upgrades.

✔ Maintenance-Free – No painting, no rotting, no hassle—just a garden room that stays looking perfect for decades.

✔ Ultra-Durable – Built with premium materials, including 6-inch composite cladding and a 50-year warranty.

✔ Fully Insulated – Optional upgrade to our premium insulation package with moisture-resistant P5 boards and laminate flooring.

✔ Custom Layouts – Choose your size, shape, doors, windows, and colour—made to order just for you.

✔ Expert Installation – Manufactured and installed by the same dedicated team for quality and continuity.

If you are after a building that is made to last forever, our steel-frame buildings are the cream. We board in OSB3, then clad the outside.

Looking for the Perfect Foundation? We’ve Got You Covered! 🏠

At Spikeows Ltd, we know that a solid and level base is the key to a long-lasting building. That’s why we offer two top-tier base options, designed to provide maximum durability and stability—unlike many companies that stake timber into the ground.

Timber Base – 25-Year Warranty

Our robust timber-framed foundation is built to UC4 standards using C24 builders-grade timber for exceptional strength and durability. Unlike the flimsy “stake-in-the-ground” bases many companies offer, our posts are set in holes that are 3ft deep and 1ft wide, filled with concrete for maximum stability. This ensures zero movement over time and a solid, long-lasting foundation.

✅ Engineered to last, with a 25-year warranty

✅ Concrete footings—not just stakes in the ground!

✅ Treated timber to resist rot, decay, and insects

Steel Ground Screw Base – Lifetime Guarantee

For the ultimate foundation, our steel ground screw system is built using galvanized heavy-duty ground screws, officially tested to support up to 7,000kg each (depending on soil conditions and specifications). These screws are the tried-and-tested solution for modern construction, widely used as foundations for entire houses.

The helical screw design is engineered to cut into and compact the soil, distributing weight evenly for maximum load-bearing strength and stability. Unlike traditional foundations, ground screws adapt to natural soil movement, preventing shifting or cracking over time. Because of their strength and reliability, they are fully recognized in UK building regulations and approved for permanent structures, making them the professional choice for foundations.

On top of the screws, we construct a UC4-treated, C24 timber frame, ensuring zero ground contact and zero risk of rot. This premium system is ideal for:

✔ Heavy gym equipment

✔ Hot tubs or high-load installations

✔ Uneven or challenging ground conditions

Backed by a Lifetime Guarantee!

Alternative Base Options

While we offer the best base solutions, you may prefer to install your own foundation. If so, we recommend:

✔ Concrete slab bases

✔ Paving slabs

✔ Decking areas

✔ Your own timber base (contact us for a diagram to ensure compatibility)

🚫 We do not recommend plastic grid systems (even when filled with shingle) as they often lack the strength needed to support heavy buildings.

🚫 We also do not recommend concreting steel posts into the ground. While this might seem like a solid option, it comes with serious risks. Metal expands and contracts with temperature changes, which can lead to stress fractures in the concrete, shifting, or structural instability over time. Additionally, moisture trapped between the steel and concrete accelerates corrosion, weakening the foundation from within. Once issues arise, repairs are costly and often require digging up the entire base—something that’s completely avoided with ground screws.

Important Information – Read Before Ordering

🔹 Ground Level Considerations – If your site has a drop of more than 2ft, please inform us before ordering. Additional materials and labor will be required, and pricing will be adjusted accordingly.

🔹 Steps Are NOT Automatically Included – If your base raises the building off the ground, steps are not included by default. Most of the time, this isn’t needed, but if you require steps, please ask us for a separate quote before installation.

A proper foundation is essential for the stability, levelness, and longevity of your building. Whether you choose one of our expert installations or lay your own foundation, we’re here to help.

Ready to build? Let’s lay the groundwork together! 🏡🔨

Our buildings are thoughtfully designed to meet practical needs while staying within planning guidelines. Externally, they stand 8ft at the ridge. For apex buildings, the eaves come down to 6ft 6”, and for pent buildings, the eaves are slightly taller at 7ft. These heights, often considered “extra height” by other companies, are standard at Spikeows.

Need something taller? Buildings exceeding 8ft in height typically require planning permission, but if you’re planning a unique project, like a golf simulator or any other purpose, we’re here to help. Send us your desired specifications, and we’ll provide a custom quote to match your requirements!

Upgrade Your Garden Room with Our Premium Insulation & Boarding Package

A well-insulated garden room isn’t just about warmth—it’s about comfort, longevity, and a professional finish. That’s why we use only the best materials, designed specifically for timber-framed buildings.

Why Our Insulation & Boarding Package Stands Out

🛑 No Cheap Rockwool Here – Many companies use Rockwool, but it’s designed for lofts, not walls, and certainly not for garden rooms. It slumps over time, absorbs moisture, and fails to provide stable insulation.

✔ We Only Use Kingspan Rigid Insulation – Superior thermal efficiency, moisture resistance, and a rigid structure that won’t settle or degrade over time.

✔ Walls Over 140mm Thick – Once insulated, our buildings feature a modern insulation cavity system, far superior to traditional log cabins, offering unmatched energy efficiency.

✔ Moisture-Resistant P5 Boarding – Unlike standard MDF or plasterboard, our P5 long grain moisture-resistant boards are:

✅ Designed for timber-framed structures

✅ Resistant to damp & warping

✅ Far stronger than plasterboard, meaning no cracks over time

🚫 Plasterboard in a Timber Building? That’s Asking for Cracks! – Timber buildings naturally move slightly with seasonal changes. Plasterboard can’t handle this, leading to cracks, splits, and a poor long-term finish.

✔ All Buildings Come with a Breathable Membrane as Standard – Proper insulation starts at the manufacturing stage. We install a breathable membrane between the cladding and framework, preventing moisture buildup and ensuring long-term structural integrity.

Choose Your Floor Finish

✔ Durable, Modern Laminate Flooring – Available in a choice of colours to match your style.

✔ Designed to Last – Installed with matching skirting boards for a complete, professional look.

The Perfect Insulated Space, Ready to Use

With our premium insulation & boarding package, your garden room will be:

✔ Warm in winter, cool in summer

✔ Properly protected against moisture

✔ Finished with a sleek, professional look

Payment Process at Spikeows Ltd

We’ve designed our payment process to be simple, secure, and transparent.

1. Deposit Payment (20%)

To secure your order, we require a 20% deposit at the time of purchase. When you add an item to your basket, you will only be asked to pay the deposit at checkout—not the full balance upfront.

We accept deposits via BACS (bank transfer) or PayPal. While BACS is our preferred method, if you choose PayPal, please be aware that any associated fees will be added to your total.

2. Final Payment

The remaining balance depends on the type of build:

• Standard Buildings: The final 80% balance is due on the day of installation and must be paid via BACS or cash.

• Massive Builds or Buildings with Insulation & Boarding: The final balance is split into two payments:

• 40% is due when the structure is delivered and installed.

• The remaining 40% is due upon completion of insulation and boarding.

💳 PayPal is NOT accepted for final payments. If you require a PayPal payment, you must cover the additional processing fees.

Finance Options

We do not offer finance directly. If you require financing, we strongly recommend arranging this yourself beforehand so that funds are available when payment is due.

This structured approach ensures a smooth transaction while keeping costs low. If you have any questions, feel free to contact us—we’re happy to help!

We offer free delivery within 50 miles of our main depot at HR7 4RX. For locations between 50 and 200 miles, delivery is charged at £1 per mile (e.g., 51 miles = £51). For locations over 200 miles, delivery is charged at £200 + £5 per mile beyond the 200-mile mark. These additional fees help cover extended travel times, accommodation costs, and bonuses for our team, as longer trips often take two days and require them to stay away from their families.

Enter your postcode at checkout, and the delivery fee will be automatically calculated.

For installations, we typically arrive between 7:00 AM and 8:00 AM. Please ensure clear access to the site, no height restrictions, and a solid, level base is ready (whether provided by us or you).

If you have any questions, feel free to contact us—we’re here to help!

If you wish to show appreciation for our workforce, the best way to tip them is by leaving a review on TrustPilot. Our teams receive bonuses based on the feedback they receive from customers, so your review directly benefits them.

If you think the team did a great job, please take a moment to let us know—it means the world to them and helps us continue to provide excellent service. Thank you!

At Spikeows, we deliver and install 15 buildings per week, with the same expert teams who manufacture your garden room also handling the installation. We do this to ensure continuity, quality control, and attention to detail from start to finish—no subcontractors, no surprises.

We don’t operate on a rigid “next available month” system. Instead, our availability fluctuates week to week depending on demand.

For example, when this was written (early March):

✔ 2 slots available at the end of March

✔ 5 slots available in April

✔ May and June – plenty of availability

✔ July and August – nearly fully booked

🚨 Popular months book quickly—we recommend reserving your preferred date early.

Smooth process from start to finish. I did a video tour with one of the lads who explained everything clearly. I’d been comparing other companies, but that call made my mind up.

We invited them out to our home to assess the space and they happily made the trip. That level of service is rare. It delayed things slightly, but helped us get the layout just right.

Galvanised Steel Framed Buildings – Built for a Lifetime

Our buildings are constructed using high-grade galvanised steel frames, engineered for unmatched strength and durability. Every frame is built to last a lifetime, with precision-welded joints and high-quality steel purlins that provide structural integrity you can rely on, year after year.

Each steel frame is fully galvanised, protecting it against rust, corrosion, and the elements—making it perfect for long-term use in all weather conditions. The frames are then boarded in moisture-resistant OSB3 for added strength and stability, before being externally cladded in your choice of premium materials to achieve the finished look you want.

Designed with function in mind, every frame comes with integrated utility access holes, allowing for easy routing of electrics and plumbing directly through the frame itself—perfect for workshops, offices, or garden rooms that need power and water.

These buildings aren’t just tough—they’re built smart, with futureproofing and flexibility at their core.
