Are house extensions better than conservatories?

It’s hard to compare the two side by side, as they serve different purposes. A house extension will feel like a true expansion of your home, while a conservatory will feel more separated. On the flip side, conservatories feel more naturally connected to your garden or outdoor space, offering a light and airy feel. In short, all of our extension options are as good as each other in their own right.

What is postcode engineering?

Our house extensions come with precision postcode engineering as standard. Implemented for structural benefit, postcode engineering predicts the average strength of wind and the regularity of adverse weather near your home. By doing this, it can be ensured that your house extension is structurally secure enough to perform in these conditions, promising complete weatherproofing and home security.
