View areasWhy PorthouseDean for Your Structural Calculations?
Structural calculations for home projects across England, Scotland and Wales: a fixed price before you commit, a delivery date you choose, and calculations that meet building control requirements.
Nationwide Coverage
We work from your drawings wherever you are in England, Scotland and Wales. If your project needs a site visit, you can add one at checkout. In Scotland, construction drawings are outside our normal scope and may be charged for.
A Delivery Date You Choose
You get a clear price before you commit, and you pick the delivery date. The price follows the date.
Fixed-Fee Pricing
A clear price before you commit.
100% Building Control Approval
Our calculations are approved by building control. If yours aren’t, you get a refund.
