If you are planning to add more space to your home, the budget is naturally going to be one of your top priorities. For decades, Warwickshire homeowners only had one real option for a solid extension: a traditional brick-and-block build.
However, with the introduction of the revolutionary hup! building system, there is now a much faster, far more energy-efficient alternative. But the big question we get asked every week at Eco Windows Ltd is: Is a hup! extension actually cheaper than a traditional build?
The short answer is that while the initial material costs can be comparable, a hup! extension offers significantly better overall value and massive hidden savings. Here is a breakdown of exactly how the hup! system compares to a traditional build financially.

1. Massive Savings on Labour and Time
The biggest hidden cost of a traditional extension is the labour. Paying a team of builders, bricklayers, and roofers to be on-site for months on end adds up incredibly fast.
Because the hup! system utilizes advanced, pre-manufactured structural insulated panels, it is clipped together on-site and can be built up to five times faster than a brick extension. A watertight structure can often be achieved in a matter of days. Less time on site means significantly lower labour costs, keeping your overall budget strictly under control.
2. No Unpredictable Weather Delays
In the UK, traditional building stops the second it starts raining, snowing, or freezing. These weather delays stretch out the project timeline, meaning you are paying for scaffolding and site setups for much longer than anticipated.
The hup! system does not rely on wet mortar or cement for its main structure. This means our installation team can build in almost any weather condition, ensuring your project finishes on time and exactly on budget.
3. Lighter Weight Means Cheaper Foundations
Traditional brick walls are incredibly heavy, requiring deep, expensive trench foundations to support them.
Because hup! walls are manufactured using highly engineered, lightweight materials, they put significantly less strain on the ground below. In many cases, this allows for simpler, more cost-effective foundation solutions, or even the ability to build on existing conservatory bases (subject to a quick structural survey).
4. Long-Term Savings on Energy Bills
When calculating the cost of an extension, you have to look at what it will cost to heat the space over the next ten years.
The hup! system features cutting-edge insulation technology that makes it five times more energy-efficient than the average UK home. It vastly outperforms traditional building regulations. By trapping the heat inside during the winter, a hup! extension will actively lower your monthly heating bills compared to a standard brick build.
5. More Space for Your Money
Because standard brick-and-block walls are so thick, they eat into the internal footprint of your new room. The hup! system’s advanced walls are much thinner while providing better insulation. This means if you build a 4m x 4m extension, a hup! build will actually give you more usable floor space inside than a brick build of the exact same size. You are literally getting more room for your money.
