Drawings & Approvals intro
Architectural Drawings, Planning and Building Regulation Support
Good drawings do far more than show what a project might look like.
They are the foundation of the approval, pricing and construction process, helping planners, building control, consultants and builders understand exactly what is being proposed.
Tholos provides architectural drawings and approval support for extensions, loft conversions, renovations and other residential projects, from the earliest measured survey through to detailed construction information.
Whether you are preparing for planning permission, Building Regulations approval or the construction stage, we can help make sure the right information is produced at the right time.
Drawings & Approvals explained
What Are Architectural Drawings Used For?
Architectural drawings communicate the design of your project clearly and accurately.
Depending on the stage of the project, they may be used to:
- show the existing property and proposed changes
- support a planning application
- demonstrate compliance with Building Regulations
- coordinate structural and technical informationcoordinate structural and technical information
- obtain quotations from builders
- guide construction on site
The level of detail required changes as the project develops.
A drawing prepared for planning permission, for example, is not necessarily detailed enough for a builder to price or construct the work accurately.
That is why understanding which drawings you need, and when you need them, is so important.
Drawings & Approvals explained
Architectural Drawings for Home Projects
Tholos produces drawings for a wide range of residential projects, including:
- house extensions
- loft conversions
- internal alterations
- renovations
- property remodelling
- changes to doors and windows
- structural alterations
- new residential layouts
Every project is different, so the drawing package should reflect the work being proposed rather than simply following a standard template.
Drawings & Approvals
Architectural Drawings for Home Projects
Most projects begin with drawings showing the property as it exists.
These are usually prepared from a measured building survey and can include floor plans, elevations and other information required to understand the existing building.
Proposed drawings then show the intended changes.
Clear existing and proposed drawings allow everyone involved in the project to understand what is being removed, retained, altered or added.
They also form the basis for many planning and Building Regulations applications.
Drawings & Approvals
Planning Drawings
Planning drawings are prepared to explain the design clearly to the local planning authority.
Depending on the project, these may include:
- existing and proposed floor plans
- elevations
- roof plans
- site plans
- location plans
- sections
- supporting design information
The exact requirements depend on the type of application and the nature of the property.
Some projects may fall under permitted development rights, while others require full planning permission or another form of approval.
Tholos can help establish which route is appropriate before the application is prepared.
Drawings & Approvals
Planning Drawings
Planning drawings are prepared to explain the design clearly to the local planning authority.
Depending on the project, these may include:
- existing and proposed floor plans
- elevations
- roof plans
- site plans
- location plans
- sections
- supporting design information
Every project is different, so the drawing package should reflect the work being proposed rather than simply following a standard template.
Drawings & Approvals
Building Regulations Drawings
Building Regulations drawings focus on how the proposed work will comply with the technical requirements that apply to construction.
These drawings usually contain significantly more detail than planning drawings.
They can cover matters such as:
- wall, floor and roof construction
- insulation
- ventilation
- drainage
- fire safety
- structural elements
- openings
- stairs
- thermal performance
- construction details
They may also need to coordinate with information produced by structural engineers or other consultants.
A project can therefore have planning permission and still require a separate package of Building Regulations information before construction begins.
Drawings & Approvals
Technical Drawings for Construction
Once approvals are in place, additional technical information may be needed before builders can accurately price and construct the project.
Construction drawings can include detailed dimensions, junctions, materials, specifications and coordination information that may not appear on earlier approval drawings.
Providing this information before obtaining final builder quotations can reduce assumptions and make different quotations easier to compare.
It can also help prevent questions, delays and unexpected decisions once work has started.
Drawings & Approvals
Drawings for Extensions, Loft Conversions and Renovations
Different types of projects create different drawing requirements.
An extension may require detailed information about the connection between the existing and new building.
A loft conversion may need sections showing headroom, roof alterations, stairs and structural changes.
A renovation may involve a combination of existing building information, internal layouts, structural alterations and detailed construction drawings.
The drawing package should therefore be developed around the actual project rather than simply producing the same set of drawings for every property.
Drawings & Approvals
From Drawings to Approval
Producing the drawings is only one part of the process.
Depending on the project, you may also need support with:
- Planning Permission
- Planning Applications
- Permitted Development
- Lawful Development Certificates
- Prior Approval
- Pre application Advice
- Planning Appeals
- Building Regulations
- Listed Building Consent
- Conservation Area requirements
Tholos can help identify which approvals apply and prepare the drawings and supporting information required for the relevant application.
Drawings & Approvals
From Approval to Construction
Approval does not automatically mean that your project is ready for a builder.
Before construction begins, you may still require:
- technical construction drawings
- structural design
- specifications
- tender information
- builder quotations
- contract documentation
This is where the Drawings & Approvals stage connects directly with Build with Tholos.
Once the design and approval information is complete, we can help you prepare the project for pricing, select a builder and move towards construction.

Frequently Asked Questions
What architectural drawings do I need?
The drawings required depend on the type of project and the stage you have reached. Planning, Building Regulations and construction each require different levels of information.
Are planning drawings enough for a builder?
Not always. Planning drawings are primarily produced for the planning process and may not contain enough technical information for accurate pricing or construction.
Do I need Building Regulations drawings if I already have planning permission?
Often, yes. Planning permission and Building Regulations are separate processes and assess different aspects of the project.
Can Tholos prepare drawings for an existing project?
Yes. We can review existing drawings and project information and help identify what additional information may be required.
What happens after the drawings are approved?
The project may then move into technical design, builder pricing, tendering and construction. Tholos can continue supporting the project through these later stages.
