What are building plans in architecture?
“Building plans architecture” typically refers to the technical drawings used to communicate a proposed design. These can be for planning applications, building regulation approval or construction.
For residential projects, building plans normally include:
- Floor plans — showing layout, dimensions and room functions.
- Elevations — showing external appearance from different sides.
- Sections — showing a slice through the building to explain height levels and construction.
- Site and location plans — showing your property in context.
Together, these help your designer, your local authority, and your builder all understand what’s being proposed.
Main types of architectural building plans
Depending on the stage of your project, you may encounter different plan types. Here’s how they typically fit together:
Planning drawings
Used to obtain planning permission or a Lawful Development Certificate. These are usually simplified and focus on the external design and site layout. You’ll often need:
- Existing and proposed floor plans
- Existing and proposed elevations
- Roof plans (for lofts or complex roofs)
- Site plans and block plans
Building Regulations drawings
These go into more technical detail and are submitted to Building Control. They show how the proposal meets fire safety, insulation, structure and drainage standards.
See our full guide on plans for Building Regulations for a breakdown of what’s required.
Construction drawings
Used by your builder on site. These often include detail beyond Building Regs, such as electrical layouts, joinery, finishes and bespoke elements.
Building plans vs architecture – what’s the difference?
Many homeowners search for “architecture plans” or “building plans” – but what’s the actual distinction?
Quick comparison
- Architecture = overall design approach, space planning, concept, materials, aesthetics.
- Building plans = the technical documents showing how that design is realised and approved.
Some designers focus on the creative side, others on producing plans that are ready for council approval and building. Ideally, your chosen professional balances both.
Not sure what drawings your council will accept?
We’ll check your council’s expectations and advise which building plans are needed to get approval first time.
Who prepares building plans – do I need an architect?
You don’t legally need an architect to draw building plans. Many are created by:
- Architectural technicians or technologists
- Design & build firms
- Specialist planning drawing services
See our comparison in architect drawings for planning permission to understand who’s best for your project.
When do you need building plans?
You’ll usually need plans when:
- You’re applying for planning permission or a Lawful Development Certificate
- You’re submitting drawings to Building Control
- Your builder needs drawings to quote or construct
FAQs: building plans architecture
Are architectural plans the same as building plans?
No — architectural plans are usually broader and conceptual, whereas building plans are the specific technical drawings submitted to authorities and used on site.
Do I need full architectural drawings for a small extension?
Often not. For a standard rear or side extension, a technician or planning drawing service can provide all the plans required for planning and Building Regulations. Our guide on extension drawings explains what’s needed.
Can I draw my own building plans?
You can, but they must meet council scale, accuracy and content requirements. Most homeowners find it’s better value to use a professional — mistakes can lead to costly delays.
Which plans are required for a planning application?
You’ll usually need existing and proposed floor plans, elevations, a site plan and a location plan. See our full guide to drawings for planning applications for more detail.
What scale should architectural plans be drawn to?
Commonly used scales include 1:100 or 1:50 for floor plans and elevations. Site and location plans use 1:200 or 1:1250. Your designer will know what your council expects.
Still unsure what plans you need?
