Architectural design in st helens
At Melrose Designs, we’re proud to support homeowners across St Helens and the surrounding areas with thoughtful, practical, and cost-effective architectural design solutions. One of our recent projects in the area was a brilliant example of how a well-designed extension can transform a home and improve everyday life.
In this blog, we’ll take you through the details of that project, what makes a successful two-storey extension, and how we can help you with your architectural design in St Helens — whether you’re just starting to plan or ready to submit drawings for approval.

Our Latest Project: A Smart Two-Storey Side Extension in St Helens
We recently designed and submitted plans for a two-storey side extension to St Helens Borough Council. The goal? To provide our clients with the additional space their growing family desperately needed — without the cost or stress of moving home.
Key Features of the Extension:
-
Ground floor playroom – A safe and spacious area for the children to enjoy, separate from the main living area.
-
New master bedroom upstairs – Complete with added privacy and extra storage, giving the homeowners their own personal retreat.
-
Cost-effective approach – Our clients asked us to retain as many of the existing structural elements as possible. This thoughtful design decision helped them significantly reduce overall building costs.
This project is a great example of how a well-planned home extension can enhance both the function and value of a property.
Thinking About a Two-Storey Extension?
If you’re considering adding a two-storey extension to your home in St Helens, there’s a lot to think about. From initial design ideas to planning permission and building regulations, the process can feel overwhelming — but that’s where we come in.
Here’s a quick breakdown of what’s involved and how we help.
Planning Permission in St Helens
For a two-storey side extension, planning permission is typically required — especially if the extension will alter the street scene or is close to the boundary of your property.
As part of our full service at Melrose Designs, we handle everything on your behalf:
-
We draw and prepare your planning application, ensuring it meets local requirements.
-
We submit the application to St Helens Council and liaise with planning officers throughout the process.
-
We make sure your design balances your needs with the requirements of your local planning authority.
Having worked on many applications in the area, we’re very familiar with planning permission in St Helens, which allows us to help you avoid common delays and rejections.
Building Regulations Drawings
Once planning permission is granted, the next step is to prepare detailed building regulations drawings. These ensure your project complies with national safety, energy efficiency, and construction standards.
We provide complete building regulations plans that include:
-
Structural layouts
-
Insulation details
-
Drainage and ventilation requirements
-
Construction methods
-
Staircase, fire safety, and accessibility requirements
These drawings are essential for your builder and are required to pass Building Control inspections. We can also coordinate with structural engineers where necessary.
