About Seven Nine

Design informed by over
30 years in construction.

I work with homeowners, landowners, schools and businesses to create detailed drawings for planning permission and building regulation purposes. Typical projects include extensions, conversions, alterations, new builds and small commercial works.

With over 30 years’ hands-on construction experience, I understand how buildings go together and design with practicality, cost and buildability in mind.

About Seven Nine

I’m Dale Smith, a draughtsman based in East Hertfordshire. My approach is simple: responsive to the client’s requirements, with practical knowledge of construction informing the design.

From the first ideas to the detailed drawings, the aim is to make the most of your property and help you take the next step with confidence.

What my clients say

Find our Google reviews
“We met with Dale and he was able to provide a great number of practical ideas due to his hands on experience in the construction industry. There aren’t many who can draw the plans, help with building approvals and then have the know-how to actually build it.”
M Bell – Puckeridge
“Dale was influential in designing our extension, he suggested ideas that we didn’t even think of. His knowledge of the local area and the planning department is what I believe meant our planning was approved first time.”
L Hutley – Bishop’s Stortford
“We have used Dale for many years now and even though he has a building company he never treads on our toes. We like how clear his drawings are for us to use and not just what goes through the planning system. We recommend him to all our clients and would have no hesitation recommending his services.”
J & K Easton Builders – Ware
