General Questions

What does a Synergy Modular Home Extension look like?

We have various design options for your home extension so you can choose the size, roof type, external finishes, windows, and doors that you want. Synergy Modular Home Extensions are individually tailored and designed to suit your needs and it is down to you what your finished extension will look like inside and out. The exterior can be matched to your existing brick or render, your roof tiles can be matched, and the interior can be finished to your choice.

Do you supply Synergy Modular Home Extensions nationwide?

Yes. We build your Synergy Modular Home Extension in our factory but we can deliver and install them nationwide.

How big can a Synergy Modular Home Extension be?

Your Synergy Modular Home Extension can be as big as you want. Our modular panels can be connected together so that any length of wall is achievable.

What kind of external finishes can I have?

We can finish your Synergy Modular Home Extension with various finishes at our factory – including a render finish, brickslips (various colours), or a cladding.

What is a Synergy Modular Home Extension built out of?

Your Synergy Modular Home Extension is built using light steel frames (LSF). These frames form the shell of your home extension and they have benefits over timber frames and traditional blockwork. For example, they can be quickly assembled and due to its lightweight structure, there is less stress load on the building foundations. LSF has excellent thermal performance and structural integrity and has proven repeatedly that it does not aid the spread of fire and is highly resistant to extra loads, infestation, weathering, and other damage.

How will my Synergy Modular Home Extension arrive – pod or panels?

Both our pods and panels are built using the exact same materials and processes. The reason we offer a panel built home extension is because it is not always logistically or economically feasible to lift a full pod over your house. Due to the weight of the full pod, a larger crane is required to lift it and sometimes the extra cost is not justifiable. Also, if your house extension is a certain size then sometimes it is simply too big to transport on the road.

Do I need to arrange a builder for my Synergy Modular Home Extension?

No. We take care of the full project for you, ensuring that everything is coordinated and runs smoothly.

How do you lift my home extension in?

Our sister company, Synergy Lifting, have installed hundreds of modular units across the UK. They supply the crane needed to lift your Synergy Modular Home Extension into position. This is all done as a fully insured operation, with risk assessment and method statements put in place. Because our sister company take care of the lifting operations in house, it means we can also do this with greater cost savings for you.

How It Compares

How is the build quality better?

We build your Synergy Modular Home Extension in our quality controlled factory where our production manager makes sure your home extension is built to the highest standard at every stage. We use light steel frames (LSF) to form the ‘shell’ of your home extension and these are cut to size by a CNC machine with extreme precision – this means that your home extension is built to precise dimensions.

How is the build time quicker?

There are various reasons why we can build your Synergy Modular Home Extension quicker than a traditional builder can. Firstly, the program is shortened – whilst we prepare your foundations on site, we have already begun building your home extension in our factory. Secondly, there are far less disruptions due to weather because the majority of works take place inside our factory – we can carry on building your home extension whilst it is raining outside. Third, building your home extension in our factory enables us to benefit from efficiencies of scale – for example, all of our material deliveries are to our factory and we keep stock instead of having multiple material deliveries being sent to multiple sites. Fourth, we have strict build programs so our staff can continue working in our well lit factory even after it gets dark outside so that we can keep on top of your build program.

How is there less disruption at my home?

With up to 90% of your Synergy Modular Home Extension being built in our factory, it means there is much less disruption being caused by builders coming to and leaving your home. The only phases we need our tradesmen at your home is to prepare the foundation, lift in your Synergy Modular Home Extension, and connect it to your existing home.

How is it more environmentally friendly?

Our factory build process means less material wastage. This is because your home extension is planned carefully and managed by our production manager who makes sure there is as little wastage as possible. There are also a reduced number of vehicle movements because we have materials bulk delivered to our factory and then your completed Synergy Modular Home Extension is sent to site in one delivery.

How is it lower cost?

There are various reasons why we can build your Synergy Modular Home Extension at a lower cost whilst also building it to a high standard. These reasons include reduced material wastage, better efficiencies, economies of scale, and quicker build times. We pass these cost savings on to you.

How is it better performing?

Your Synergy Modular Home Extension is designed and built to have a high performing acoustic and thermally insulated wall construction which leads to reduced energy costs compared to alternative extensions.
