I hired NSP Architectural to produce drawings and put in planning permission for an upcoming rear extension and they have been nothing short of superb. I was impressed from Nathan's first visit as he was so professional and sought to gain a thorough understanding of the job and gave great advice on how to approach the planning application to achieve what we wanted. The drawings were done in a timely manner and Nathan was more than happy to discuss my queries with a follow up video call. The planning permission went through smoothly and Nathan recommended builders and dealt with the structural engineer to make sure everything was aligned with our plans.
Architectural design studio · Essex & East London
Don't move. Transform the home you already love.
We're a design-led studio, not just a drawing service. NSP Architectural takes your project from first sketch through planning and Building Regulations, and connects you with the engineers and builders who make it real.
What we do
More than a drawing service. We look at how you actually live, then design for light, flow and space you didn't know was there.
Design that earns its keep
Most clients come to us to improve their home rather than move. We find the opportunities a floor plan alone won't show you.
One team, the whole journey
From feasibility and concept design to planning submissions and the technical package your builder needs on site.
Local, and properly so
We understand the planning context across Essex and East London, including the requirements of local authorities such as Havering and Thurrock

The difference design makes.
Same footprint, transformed. These homes were reimagined, not replaced - to add space, light and serious kerb appeal.
Beyond design
We don't stop
at the drawings.
Where your project requires additional professional input, we can introduce trusted specialists and help coordinate the wider process through planning, Building Regulations and construction.
Structural engineers
We work with trusted structural engineers throughout, so calculations and coordination happen alongside the architectural design, not as an afterthought.
