ARCHITECTURAL SERVICES & DESIGN
Architectural Design Services From Brief to Planning Permission
Our approach to design starts with listening. We take time to understand each client's needs before we draw a single line. Whether you want to create your dream home, convert a commercial building into flats, or develop a new-build scheme, we provide design solutions that balance your vision with planning policy, structural reality, and build cost.
We design buildings and spaces that work efficiently, look right in their setting, and perform to modern standards. Every scheme goes through rigorous review against local planning policy before submission so the design lands well with the authority — not just on screen.
Feasibility Studies and Concept Design
Before committing to a full architectural project, a feasibility study tells you what is realistically achievable on your site. We assess planning constraints, permitted development rights, structural implications, and indicative build costs so you can make an informed decision.
This early-stage advice saves homeowners and developers significant time and money before any design fees are committed.
Home Extension Architecture
A home extension project is one of the most effective home improvement investments in the London domestic market. We design single-storey rear extensions, double-storey side returns, and wrap-around layouts, creating new space that improves everyday living while adding measurable property value.
Every design respects the existing character of the building and the streetscape requirements of the local authority.

Technical Drawings, Planning Applications and Loft Conversions
Technical Drawings and Architectural Documentation
We draw up plans using industry-standard design tools including Revit and AutoCAD, producing a detailed set of architectural drawings that covers every technical requirement.
Our packages include plans, elevations, sections, structural layouts, insulation specifications, fire safety routes, drainage, and ventilation — everything Building Control and your contractor needs in one coordinated package.
Planning Applications — Prepare and Submit with Confidence
Most London developments require planning consent before work can begin. Our team prepares and submits full planning applications across all 32 London boroughs, from Westminster and Camden to Hounslow and Richmond.
We liaise directly with planning officers, respond to requests for information, and manage the entire process to obtain all necessary approvals on your behalf. If circumstances change after submission, we can advise on how to make changes to a planning application without losing momentum.
We streamline the process by preparing design and access statements, heritage assessments, daylight and sunlight reports, and any specialist documents required by the local authority. Our 94% first-submission approval rate reflects the care we put into every application before it is lodged.
Loft Conversions
A loft conversion can add up to 30% more usable floor area and is one of the most cost-effective ways to extend your home without losing garden space.
We design every type of conversion — dormer, mansard, hip-to-gable, and rooflight — confirming at the outset whether permitted development rights apply or a full planning application is required.

Property Conversions and Change of Use
Converting buildings for new uses is one of our core service areas. We handle a range of projects including commercial-to-residential conversions, HMO designs, house-to-flat conversions, and mixed-use schemes.
Our team ensures full compliance with planning policy, building regulations, and fire safety requirements throughout every stage of the project.

Our Architectural Design Process
Every project starts with a free consultation. We discuss goals, budget, and timescale. Next, we carry out a laser-measured site survey to record every detail. This accurate base ensures smooth design and planning and precise construction drawings later.

Once planning is approved, we prepare a full set of construction drawings for Building Control. Our structural engineers coordinate with designers to ensure every element fits together. The result is a ready-to-build package that contractors can price and construct confidently.

FAQ
Do I need an architectural designer or can I draw plans myself?
You can submit your own plans. However, most councils expect professional architectural drawings showing compliance with current standards.
Working with an experienced London design consultancy improves accuracy and approval rates significantly — and reduces the risk of costly amendments after submission.
How long does the architectural process take?
Concept design: 2–3 weeks
Planning drawings: 1–2 weeks
Planning determination: 8–13 weeks
Building Regulation drawings: 2–3 weeks
Building Control approval: 5–10 days
Fast-track services are available for time-sensitive projects.
What is the difference between planning permission and building regulations?
Our architectural services manage both so your building work stays compliant at every stage from initial concept through to completion on site.
Can you work with my builder?
Yes. We work with your chosen builder or recommend trusted construction specialists who understand our drawings and can price accurately from our detailed set of documents.
What information do you need to start?
Property address and ownership details
Outline of requirements and budget
Existing drawings or surveys
Photos of current conditions
We can arrange missing information through our architectural consultancy services.
When are building regulations required for my project?
Building regulations are required for most building projects, including extensions and loft conversions, structural alterations, new builds and major renovations, installing new windows or doors, electrical work and plumbing installations, garage conversions, and any work affecting fire safety or structural integrity.
Some minor works may be exempt our team can assess your specific project and advise whether obtaining building regulations approval is needed.
