Terrence is an architectural design studio working with homeowners across London on extensions, loft conversions, and home renovations. We produce clear, considered drawings that get planning approval and projects onto site — without unnecessary cost.
We provide architectural drawing services to homeowners across London — from initial design advice through to planning and construction drawings — at a price that makes sense for a residential project. We also act as Principal Designer under CDM regulations where required.
Select the elements that apply to your project. We offer two packages: planning drawings submitted to your council for permission, and construction drawings — a more detailed set your contractor uses to price and build. Choose one or both.

Terrence is led by Oliver Partington, an architect by training with over 15 years of experience at some of London’s most respected practices, including Allies and Morrison, Mæ, and Parti. We set up Terrence to make genuinely good architectural design accessible to homeowners, at a cost that reflects the scale of a residential project.
We work across London on ground floor extensions, loft conversions, side returns, and internal renovations, producing planning and construction drawings that are clear, buildable, and competitively priced.
