Recommended Architects
Architects We Work With and Recommend
Finding the right architect is the first step toward a successful build. We work with trusted architectural practices who produce clear, buildable drawings and understand how design decisions affect construction cost, programme and quality.
Why We Recommend Specific Architects
Not all architects produce drawings that are ready for construction pricing. Over 20 years of building, we have learned which practices produce work that translates smoothly from design to site. We recommend architects based on three criteria:
Drawing Quality
Their drawings must be detailed enough to price and build from. We look for proper dimensions, clear specifications, coordinated structural details and realistic construction sequences.
Client Communication
They must communicate clearly with clients, manage expectations about timelines and costs, and maintain professional standards throughout the project.
Buildability
They must understand how buildings are actually constructed. Beautiful designs that cannot be built efficiently or affordably do not serve the client well.
Our Recommended Architects
These are architectural practices we have worked with on real projects and can recommend with confidence. Each has been vetted through actual collaboration.

Are You an Architect?
We are always looking to partner with quality architectural practices. If you produce clear, buildable drawings and want to work with a principal contractor who respects your design intent, get in touch.
Learn About Partnering With RCBUnderstanding Architectural Drawings
If you are planning a building project, you will hear architects and builders talk about different types of drawings. Here is a plain-English guide to what each type is, why it matters and what it typically costs.
Costs shown are typical ranges for residential projects in London and the South East as of 2026. Actual fees depend on project size and complexity.
Measured Survey Drawings
Also called: existing plans, as-built drawings
The starting point for any project. A measured survey records the existing building exactly as it stands today, with accurate dimensions, floor levels, wall positions and key features. Everything that follows is based on these measurements.
Why it matters:
If the survey is inaccurate, every drawing that follows will be wrong. A proper measured survey prevents costly surprises when construction starts.
Typical Fee Range
£400 - 1,500
ex VAT
Concept / Sketch Designs
Also called: feasibility drawings, initial layouts
Early-stage drawings that explore what is possible. The architect tests different layouts, sizes and configurations to help you understand your options before committing to a full design. These are usually not submitted to planning.
Why it matters:
This is where you shape the project. Changes at concept stage cost nothing. Changes during construction cost thousands.
Typical Fee Range
£500 - 2,000
ex VAT
Planning Application Drawings
Also called: planning drawings, planning set
The formal drawings submitted to your local council for planning permission. They show what you want to build at a level of detail the planning authority needs to make a decision. Typically include site plans, floor plans, elevations and sometimes sections.
Why it matters:
These drawings must meet specific council requirements. Missing information causes delays. A good architect knows exactly what each borough or district expects.
Typical Fee Range
£1,500 - 4,000
ex VAT
Building Regulations Drawings
Also called: technical drawings, building control drawings, Part L/B/M drawings
Detailed technical drawings that show how the building will actually be constructed. They cover structural details, insulation, fire safety, ventilation, drainage and accessibility. These are what the building inspector checks against during construction.
Why it matters:
Planning permission says you CAN build. Building regulations drawings show HOW to build it safely and legally. Without these, no building inspector will sign off the work.
Typical Fee Range
£2,000 - 6,000
ex VAT
Structural Engineering Drawings
Also called: structural calculations, beam designs, foundation details
Produced by a structural engineer (not the architect), these show the structural elements: steel beams, lintels, foundations, floor joists and load paths. The architect coordinates with the engineer to make sure the structure works with the design.
Why it matters:
Any wall removal, extension or loft conversion needs structural engineering input. Without it, the builder cannot order steels, the building inspector will not approve the work, and the building may not be safe.
Typical Fee Range
£800 - 3,000
ex VAT
3D Visualisations & Renders
Also called: CGIs, 3D views, photo-realistic renders
Computer-generated images that show what the finished project will look like. Some architects include basic 3D views as part of their service; photo-realistic renders are usually an add-on. Useful for planning applications in sensitive areas and for helping clients visualise the result.
Why it matters:
Flat drawings can be hard to read. A 3D view helps you and your family understand exactly what you are getting before a single brick is laid.
Typical Fee Range
£300 - 1,500 (add-on)
ex VAT
How Your Drawings Affect Your Build Price
The quality of your architectural drawings directly impacts the accuracy and competitiveness of the build price you receive. Here is why.
Better Drawings = Better Prices
A complete set of construction-ready drawings means the builder can price accurately. Missing details force builders to add contingency or make assumptions — both cost you money.
Planning Drawings Are Not Enough to Build From
A common mistake: clients get planning approval and assume those drawings are enough to start building. They are not. Building regulations drawings and structural details are needed before construction can begin.
The Gap Between Design and Build
The best architects produce drawings that are genuinely buildable. The worst produce beautiful images that leave the builder guessing. RCB recommends architects who understand construction, not just design.
Coordination Saves Time and Money
When the architect, structural engineer and builder are all working from the same coordinated set of drawings, issues get caught on paper instead of on site.
The Drawing Journey: From Idea to Build
Here is how drawings typically progress from initial concept through to construction-ready packages. Understanding this timeline helps you plan your project and budget.
Measured Survey
1 - 2 weeks
Architect visits your property and records accurate measurements of the existing building.
Concept Design
2 - 4 weeks
Architect develops layout options based on your brief. You review, discuss and refine until the design direction is agreed.
Planning Application
2 - 3 weeks to prepare, then 8 - 13 weeks for council decision
Formal drawings prepared and submitted to the local planning authority. The architect manages the application process.
Building Regulations Drawings
3 - 6 weeks after planning approval
Detailed technical drawings produced showing construction methods, insulation, structural details and compliance with building regulations.
Structural Engineering
2 - 4 weeks (often runs alongside step 4)
Structural engineer produces calculations and drawings for beams, foundations, floor structures and any load-bearing changes.
Tender & Construction
Ongoing
Complete drawing package sent to RCB for pricing. Once agreed, these drawings guide the entire construction process.
