Design, Planning and Project Management

With a mission to bring the benefits of SIP Construction to the home adaptation and new-build market, we specialise in both low volume bespoke projects and ‘one-offs’.

We offer a full turnkey service from inception through to sign off – including planning applications and all onsite enabling works.

SIP Construction

SIP Advantages
SIP Construction Process
VERY Fast Construction Time
With the Samspson Modular System the weather has little or no effect on site construction time. A typical build could be weather proof within a few days.

Cost Effective, Precise Budgeting
SIP construction allows you to budget with confidence. Faster construction time means less cost overall with no overruns and no hidden charges

Full Design Service
Our inhouse graphics team will guide you through all the design stages of your project with state of the art imagery that provides fully detailed visualisations of how the finished project will look.

A Greener Solution
With Traditional Construction, 10% of all building materials delivered to site is waste and finishes up in the skip. With SIP construction waste runs at less than 1%, greatly reducing the carbon footprint and the overall cost.

Less Disruption To Your Home
Projects are completed in a fraction of the time compared to traditional builds. SIP buildings can be completed in as little as a few weeks, meaning you won’t have builders and their equipment on site for months on end.

Guaranteed Workmanship
Samspson Modular provide a 2 Year Material Warranty and a 10 Year Structural Warranty in addition to meeting all statutory requirements and building regulations.
Site Survey
We’ll visit the site to take measurements and plot the drain, waste and service runs. We also carry out ground and structural surveys as necessary.

Planning Application
If you wish, we can prepare planning drawings and help secure planning permission for your project.

Quote And Design
Our designers will work with you to agree your final specification before offering a firm quotation.

Project Management
You’ll have a dedicated point of contact at Sampson Modular, and full and transparent access to all aspects of the project as it progresses.

Once you’ve agreed your design and accepted our quote, manufacturing will begin.

We carefully coordinate our manufacturing and installation teams to fast track your project and ensure all work is completed to your satisfaction in the shortest time possible.
