Our Philosophy

At Alden Rose we are committed to helping repair our planet, one house at a time.  With years of research into the role that the built environment has played in the world’s total carbon emissions, we work alongside homeowners, social housing associations and private landlords to build houses that are fit for our future generations.

Combining 25 years of experience with a accreditations for PAS2035, Passivhaus, EnerPHit and NZEB building standards, we provide our clients with long term realistic and affordable solutions to ensure that their property is ready to meet the legally binding global targets for 2050.

The rising challenges around the world are forcing millions into fuel poverty and poor living conditions.  From simple techniques to deep retrofitting, every home can be healthy and cheap to run.

We can provide “passports” for homes detailing the long term goals to be achieved to suit the homeowner’s budget, assist with applying for grants available, or design a new home that far exceeds current UK building standards.

We work with manufacturers and suppliers throughout the world, and can apply the Passivhaus Principles to most buildings, old or new, to create the optimum healthy environment to live or work in.

Having studied global building standards and methods for nearly a decade, we have seen how far behind the UK is in terms of our built environment. We hope to raise awareness of the work to be done over the next two decades.

We can live in harmony with mother nature if we take that first step.
