Modular Extensions & Garden Rooms

Do you want a cost-effective and time saving extension on your house?

Extend your home

Are you looking for a way to expand your home without spending a fortune?

With a Durabase, you can easily add a home extension to your house.

Add the extension you have always wanted. Build a garden room that you would love.

What a Durabase can be used for

We use Durabase to build single-storey extensions on homes. We can also use it to build standalone garden rooms.

A Durabse can be installed on Ground Screws. Then a steel base frame sits on top. This provides a fast and efficient foundation for walls and floors.

With every extension being bespoke, we have a working relationship with manufacturers to deliver exactly what you have in mind.

Why is a Durabase better?

It's Quicker - If you choose our foundation base construction, your extension can be built quickly and easily on ground screws. Once a steel frame base has been installed, real brick modular walls can be put together in a matter of hours.

Cost Effective - No need for expensive relocating of manholes or drains. When work is required in tight spaces, traditional foundations would need deeper excavation. Durabase can work around existing structures.

Worry-Free - A 25-year guarantee gives you peace of mind with Durabase.

FASTER

While there is no such thing as an instant home extension, we, as a company, want to increase significantly the speed in which these structures can be made.

CLEANER

As our modular house extensions are fabricated off-site, you will not have to worry about the mess of a typical build. Foundations will not have to be dug to such a dramatic degree.

COST EFFECTIVE

As stated before, our modular home extensions are great because they dramatically reduce the costs that are associated with extending properties.

Compare a Durabase extension to a traditional extension

Once you have submitted your site survey, our sales time will send you the pad plan. In the following weeks your entire order will be delivered for installation. Fitters arrive and everything is ready to go.
It's Cost Effective
Modular house extensions are great for saving money. That is because they don’t require the same amount of workforce to build. Nor do they need all the construction equipment and skips that are needed to get rid of waste. Save money today and invest in only the best.
Less Mess, Less Waste!
The only foundations required are a number of Ground Screws placed at strategic points around the base. This means far less excavation work and waste materials to dispose of compared to other methods of base construction.
Worry-Free With Our Warranty
A 25 year guarantee gives you peace of mind with Durabase and what's better still is that this is standard across all our products.

It's Slower
With a wet extension, it's slower due to digging out the foundations, removing waste material and forming and pouring a reinforced concrete slab. This can take weeks and increase the cost of the project.

It's Easier
Once we have completed your site survey, We can get to work on a foundation plan for concrete pads/ground screws. Once your order is placed there is a 4-5 week lead time before delivery to site ready for installation. Our tradesmen arrive and everything is ready to go.
It's Harder
Traditional, wet systems are often messy and require extra equipment to complete. This method is also dependent on multiple product deliveries turning up on time, turning homes into building sites. You can also experience hold-ups due to the wet and cold weather.

It's More Expensive
Wet systems need a lot more workforce to ensure a perfect installation. Our modular house extensions completely remove the need for excessive amounts of workforce to be on site. By opting for a traditional system, you will be spending far more money. Not only this, but you will be waiting a long time for the installation to be finished.

Difficult Sites = Difficult Builds
Unlike with Durabase, if you have uneven or sloping sites or maybe a site with difficult access? This can cause issues during build process including delays, and further costs incurred.

WITHIN 9 Days Built

We can have a Durabase extension built within 9 days. This is a saving of over 7 days of labour, not to mention the mess and disruption that comes with days of digging deep holes for the foundation.  Ready for the internal works to begin.

This is also perfect for houses where the place you want the extension is limited by access. In a traditional build, you would need a mini digger to help dig the foundations. If you can't use a digger, this means the foundations need to be dug by hand, adding even more time onto the built (and expensive!!).

When the work started, the team did what they said they would, on time. Dan provided regular updates and photos of the work, as I was not there to see it. Work was completed to a high standard and I would have no hesitation in recommending Precision Builders. They will be my first choice for any future work on the property.

What is a Ground Screw?

Ground screws are durable steel screws installed in the ground to provide a strong foundation for structures like buildings, decks, and fences without needing concrete.

Are you trying to decide between using concrete blocks or ground screws? There’s no need to ask: There’s a ground screw for every project.

Beam screw, post screw, adapter screw and pipe screw – we have four basic models of screw with different brackets, lengths and measurements depending on what is to be anchored, what the load requirements are and the ground conditions where the screws are to be installed.

As well as all this, we have a number of attachments for special installations. Where you need a concrete supporting block, we can install a screw!
