RIBA Chartered Architect Windsor
If you're looking for an architect in Windsor, you may be planning an extension, a refurbishment, a new-build property, or changes to a property that no longer suits the way it is used. You may know what you would like to change without knowing what planning will allow, what the work will involve, or which approach makes the most sense. Planning, structure, cost and construction are closely connected. Considering them together from the start leads to better decisions and fewer surprises later. I'm a RIBA Chartered Architect helping residential and commercial clients in Windsor develop clear, practical designs, with guidance from the first ideas through to completion.
- RIBA Chartered practice
- 30 years' multidisciplinary experience
- Support through all seven RIBA stages
I understand how much rides on getting a project like this right
A substantial change to a property involves important decisions about design, planning, cost and construction. Before you commit, you need to know that the proposal is right for the property, has a realistic route through planning and can be delivered within the investment you have in mind.
- What is not working now and which changes would make the greatest practical difference
- Whether reconfiguration, an extension, a conversion, refurbishment or a new-build property is the right approach
- What the Royal Borough of Windsor and Maidenhead is likely to permit
- How heritage, neighbouring properties, trees, access or flood risk may affect the design
- Which surveys, structural advice and specialist reports will be needed
- How the design and specification will affect the cost and complexity of the work
My role is to help you make these decisions in the right order, then turn the approach we agree into drawings and information that can be approved, priced and built.
The right changes should improve the property as a whole
The best answer may be an extension, but it may equally be a better internal arrangement, a careful refurbishment or a new-build property on the site. The important part is that every decision supports the property as a whole. Layout, daylight, circulation, privacy, materials and construction all need to be considered together.- A layout based on how the property needs to be used
- New work that sits comfortably with the existing property and plot
- Daylight, privacy and the relationship with outside space considered early
- Planning and technical drawings prepared with cost and construction in mind
Architectural support from the first ideas through to completion
I work with property owners, developers and businesses in Windsor and the surrounding area. I can assess the initial options, prepare the design and planning application, produce the technical drawings and remain involved while the work is being priced and carried out.
Extensions, lofts and refurbishments
An extension or refurbishment should improve more than the area being changed. I look at the existing layout, structure, daylight and relationship with outside space before deciding where new work should go.- Rear, side and two-storey extensions
- Loft and garage conversions
- Internal reconfiguration
- Full property renovations and refurbishments
New-build and larger projects
Design and coordination for individual new-build properties, replacement dwellings and larger residential or commercial projects, with the site, planning position, construction and budget considered from the outset.- New-build properties and replacement dwellings
- Substantial residential projects
- Feasibility and site studies
- Commercial and mixed-use work
Listed, period and conservation properties
Work to an older or protected property needs a clear understanding of its character, construction and significance, as well as the changes required for modern use.- Alterations to listed properties
- Conservation-area projects
- Period-property restoration
- Extensions to historic properties
Every Windsor property needs to be considered on its own merits
Windsor includes Georgian and Victorian terraces close to the centre, larger villas around Kings Road and Clarence Crescent, established properties in Clewer and Dedworth, and sites close to the Thames or Windsor Great Park. The right design depends on the property itself, its plot, its neighbours and the planning context.
Planning applications in the Royal Borough
Windsor falls within the Royal Borough of Windsor and Maidenhead. I review the property's planning history, the relevant planning policies, local design guidance and comparable decisions before developing the proposal.Conservation areas and listed properties
Parts of Windsor, including the Town Centre, Inner Windsor and Trinity Place and Clarence Crescent, are protected for their architectural and historic character. Where this applies, the scale, roof form, windows, materials and boundary treatment need particular care. Listed properties may also require listed-building consent.Terraces, villas and established streets
Windsor has many Georgian and Victorian terraces, semi-detached properties and larger villas. Extensions and roof alterations need to respect the proportions of the original property and the rhythm of the street, while also dealing properly with privacy, daylight and neighbouring properties.River, trees and site conditions
For some properties near the Thames and in nearby Old Windsor or Datchet, flood risk and drainage may need to be assessed. Protected trees, mature gardens, restricted access and ground conditions can also affect the design and construction method. These matters are best identified before too much design work has been completed.- Planning history and design guidance
- Listed or conservation status
- Neighbours, privacy and daylight
- Protected trees and landscaping
- Flood risk, drainage and access
- Structure, budget and buildability
Experience that connects design, planning and construction
Composition Design is my RIBA Chartered architecture practice. I have thirty years of experience across residential, commercial and leisure projects, including time as a director of a design-and-build practice. That background means I look beyond the planning drawings. I consider how the proposed work will be structured, how junctions and materials will work, where unnecessary complexity can be avoided and what the contractor will need to price the work accurately. I can remain involved through the detailed design, tender and construction stages, helping to ensure the work carried out at the property follows the agreed design.Some of my recently completed projects
These projects show how layout, structure, daylight and external appearance can be considered together as part of one clear design.
How we get your Windsor project started
I review the property
Send me the property address and a brief outline of what you are considering. I review the property, its setting and the initial planning position before we speak.We discuss the project
We talk through the property, what you would like to change, your priorities and any concerns about planning, cost, timing or construction.You receive a tailored proposal
After our discussion and, where appropriate, a visit to the property, I set out the recommended services, fees and next steps before you decide whether to proceed.Trusted by property owners, developers and businesses
We worked with Jonathan on plans for a loft conversion and a ground-floor kitchen extension. Our ideas were listened to, and Jonathan provided great insight into what we could and couldn't do in terms of our council's restrictions. The process was quick, and we were also thankful for the builder recommendations.
Jonathan provided creative options to maximise the use of the space, and the end result has transformed our home. He was hands-on throughout, from the initial design concepts to managing the planning process, coordinating with the builders and providing practical advice when we needed it.
Jonathan showed a remarkable ability to blend creative vision with practical execution. When challenges arose, he adapted and worked closely with us and the builders to keep everyone aligned. The completed extension and loft conversion exceeded our expectations.

Frequently asked questions
Will my Windsor project need planning permission?
It depends on the property and the proposed work. Some alterations may fall within permitted development, while larger extensions, flats, listed properties and properties affected by specific planning controls will require an application or another formal consent. I review the property before recommending the appropriate route.Which council handles planning applications in Windsor?
Planning applications in Windsor are handled by the Royal Borough of Windsor and Maidenhead. Before preparing a design, I review the property's planning history, the relevant policies and local design guidance.Can you help with a listed property or one in a conservation area?
Yes. I assess the property and its setting, identify the features that need to be retained and prepare a design that responds to the original architecture. Depending on the property, the work may require planning permission, listed-building consent or supporting heritage information.Can you design an extension to a Georgian or Victorian property?
Yes. The design needs to improve the internal arrangement while respecting the proportions, roof form, materials and character of the original property. On terraces and closely spaced streets, neighbouring daylight, privacy and the appearance of the wider row also need to be considered.Will flood risk affect my project?
Only some properties are affected. For sites near the Thames or in lower-lying parts of Windsor and the surrounding villages, I check the available flood-risk information early. Where required, a flood-risk assessment, drainage advice or other specialist input can then be incorporated into the design.Do you only prepare planning drawings?
No. I can remain involved through all seven RIBA work stages, including feasibility, concept design, planning, Building Regulations and construction drawings, tendering, contractor coordination and support while the work is carried out.Which parts of Windsor do you cover?
I work throughout Windsor, including the town centre, Inner Windsor, Park Street, Kings Road, Clarence Crescent, Clewer, Dedworth and West Windsor, as well as Old Windsor, Datchet, Eton, Ascot, Sunningdale and Virginia Water.Let's discuss what you would like to change about your Windsor property
