Simple Building Regulations

hup! has been approved by Assent and Stroma making Building Regulation compliance far simpler. As Building Regulation requirements differ by project type, we have agreed specific procedures and prices for different types of hup! projects with both companies to ensure you have price reassurance and consistency.

You can choose to work with either Assent or Stroma to carry out your Building Regulation approvals as a simple alternative to working with a Local Authority.

Conservatory transformations

Extension-like conservatory upgrades
hup! can transform an old conservatory into a modern, energy efficient extension. Upgrade to a high performance glass roof, or choose a super-insulated solid roof with rooflights to transform the thermal performance of conservatories and still keep the natural light in any adjoining rooms.


Five times faster than traditional methods
hup! extensions are extremely fast to build and easier to project manage. A hup! extension can be five times more thermally efficient than the average UK home and have plenty of natural light.


As energy efficient as an extension
hup! conservatories have the benefits of natural light and views of the garden combined with the thermal performance of an extension.

Garden Homes

Create additional living space and transform gardens
As well as home extensions, hup! is also the ideal choice for building a garden home for family members who require their own living space in the privacy of the garden, with all the comfort of the home.
