Bristol Architects
Residential and Commercial Architecture Across Bristol and the South West
Bristol Architects with Real Knowledge of the City and Region
Dennis Hellyar Architects is a RIBA chartered practice and a team of architects serving homeowners, businesses and organisations across Bristol, South Gloucestershire, North Somerset and the wider South West. We deliver house extensions, planning drawings, commercial projects and full architectural services, drawing on over 30 years of experience and a deep understanding of the planning and built environment across both sides of the Severn. Our studio is based in Barry, South Wales, within easy reach of Bristol via the M4 corridor.
Bristol is one of the most architecturally varied cities in England. Georgian terraces and crescents in Clifton and Redland, Victorian villas in Cotham and Westbury Park, industrial conversions and waterfront developments in Harbourside and Bedminster, and a growing range of contemporary new builds across the city's expanding fringe. Each area has its own planning history, its own conservation context and its own set of design considerations.
As architects operating across the South West, we understand how Bristol City Council and the neighbouring authorities of South Gloucestershire and North Somerset approach planning applications. We know what matters in a conservation area in Clifton versus a standard residential zone in Bishopston, and how to prepare proposals that move forward with confidence.
Whether you are a homeowner in Redland looking to extend, a business in the city centre planning a remodel, or an organisation in South Gloucestershire with a commercial brief, we bring the professional rigour, design quality and practical thinking your project needs.
Bristol Architecture Projects We Have Delivered
Here is a selection of projects we have completed for clients across the South West and South Wales. Each one started with a conversation.
Architectural Services for Bristol Clients
As architects in Bristol working across both the residential and commercial sectors, we offer a full range of services from initial idea through to completed building. Here is what we most commonly help with:
House Extensions in Bristol
House extensions are one of the most popular projects we deliver across Bristol's residential neighbourhoods. Whether you are planning a rear extension to open up a Victorian terrace in Redland, a side return on a period property in Clifton, or a two-storey addition to a family home in Bishopston or Horfield, we design extensions that respond to your home's character and meet Bristol City Council's planning requirements.
Planning Drawings and Applications
Getting planning permission in Bristol requires a clear understanding of the city's planning policies. Bristol City Council has detailed guidance on design quality, conservation areas and the city's many Article 4 directions, which remove permitted development rights across large parts of inner Bristol. We prepare professional planning drawings and supporting documents and manage the submission process on your behalf, giving your application the best possible chance of approval.
Feasibility and Early Advice
Not sure what is achievable with your Bristol property? We offer early-stage feasibility advice for residential and commercial clients, assessing your site, reviewing planning constraints and giving you an honest picture of your options before you commit. This is particularly valuable in Bristol where Article 4 directions and conservation area designations affect a large proportion of the housing stock.
Full Architectural Services
For clients who want complete support from first idea to finished building, we offer a full architectural service. We manage the design, coordinate with structural engineers and specialist consultants, handle planning and building regulations, and administer the building contract throughout construction. One team, one point of contact, from the first sketch to final handover.
Commercial Architecture in Bristol and the South West
Alongside residential work, we deliver commercial architecture for businesses and organisations across Bristol and the South West. Our commercial experience spans office remodelling, light industrial facilities, community buildings and social housing, and we are well-versed in navigating the planning and regulatory frameworks that apply to commercial development in Bristol, South Gloucestershire and North Somerset.
Award-Winning Architectural Firm
Founded in 2013 after 20 years at large practices, Dennis Hellyar Architects brings the rigour of a bigger firm with the personal service clients value most. We are registered with the Architects Registration Board and hold Certified Passive House Designer accreditation, making us well-placed to advise on energy performance and sustainability across all project types.
From residential extensions in Pontcanna to a £27M social housing regeneration scheme for Cardiff City Council, our track record speaks for itself. Our Cwrt Parc development won the Best Social Housing Award at the Building Excellence Awards 2020.
How Our Architects Work With You
If you have not worked with architects before, here is how our process typically works from first contact to completed project. Not every client needs all of these stages. We are equally happy to provide exactly the level of service your project requires.
Step 1: Initial conversation
We listen to what you are hoping to achieve. There is no commitment at this stage, just a clear conversation about your project, your property and what is realistic within Bristol's planning framework.
Step 2: Feasibility and early advice
We assess your property, check whether an Article 4 direction or conservation area designation applies, review the relevant planning policies and give you a clear picture of your options before any design work begins.
Step 3: Design development
We develop the design in close collaboration with you, using 3D models and visualisations to communicate proposals clearly. For projects in Bristol's conservation areas we take particular care to develop designs that respond to the local character and will be well-received by the planning authority.
Step 4: Planning drawings and submission
We prepare professional planning drawings and manage the submission to Bristol City Council or the relevant local authority on your behalf, drawing on our knowledge of what each authority expects from a well-prepared application.
Step 5: Building regulations and construction
Once planning is approved, we can take the project through building regulations, tender and construction, remaining your single point of contact throughout the build.

Bristol Areas We Cover
We work across Bristol and the wider South West region. Here are the main areas where we deliver projects. If your area is not listed, get in touch to confirm we cover your location.
Central Bristol and Inner Suburbs
We work across the city centre, Harbourside, Clifton, Redland, Cotham, Bishopston and Montpelier. These areas include a high concentration of Georgian, Victorian and Edwardian properties, many of which sit within conservation areas or are subject to Article 4 directions. Our familiarity with Bristol City Council's policies for these sensitive locations means we can design proposals that achieve planning approval while delivering what clients need.
North and North West Bristol
We cover Westbury-on-Trym, Henleaze, Horfield, Filton and the surrounding areas. These predominantly residential neighbourhoods feature a mix of interwar and postwar housing types where rear extensions and loft conversions are among the most common projects. We are experienced in delivering planning applications across this part of the city and into South Gloucestershire.
South Bristol
We work across Bedminster, Southville, Brislington, Knowle and the broader south Bristol area. Bedminster and Southville have seen significant regeneration interest in recent years, with a growing demand for extensions and remodelling projects in the area's Victorian and interwar terraces. We cover these postcodes and the neighbouring areas of North Somerset including Nailsea and Clevedon.
South Gloucestershire and the M4 Corridor
Our studio in Barry is well-placed to serve clients along the M4 corridor, covering Chepstow, Caldicot, Newport, Monmouthshire and into South Gloucestershire. For clients in Thornbury, Yate, Chipping Sodbury and the surrounding areas, we offer the same full range of services as we do in Bristol itself, with the added advantage of our South Wales planning knowledge for cross-border projects.
Planning Permission in Bristol: What You Need to Know
As Bristol architects, understanding the planning framework that governs development across the city is central to what we do. Bristol has some specific planning considerations that make local knowledge particularly important. Here is a plain-language overview of the key things that affect most projects.
Article 4 directions in Bristol
Bristol City Council has issued Article 4 directions across large parts of the inner city, removing permitted development rights from many residential properties. This means that works you could carry out without planning permission elsewhere in England may require a formal application in Bristol. Article 4 directions typically apply in conservation areas and established residential neighbourhoods. We can confirm whether an Article 4 direction applies to your property and advise on the best route forward.
Conservation areas in Bristol
Bristol has an extensive network of conservation areas, including Clifton, Redland, Montpelier, Cotham and parts of Bedminster and Southville. Development in these areas is subject to stricter design requirements around materials, scale and appearance, and permitted development rights are more restricted. Our experience working within Bristol's conservation areas means we understand how to design proposals that satisfy the local authority while delivering what clients need.
Bristol City Council's planning approach
Bristol City Council places a strong emphasis on design quality, sustainability and the character of existing streets and neighbourhoods. Their planning team expects proposals to demonstrate how a design responds to its context, and applications that are poorly presented or inadequately justified are likely to face resistance. We prepare applications that anticipate these requirements and present proposals clearly, giving your project the best possible start.
Common Questions About Working with Architects in Bristol
-
Look for a RIBA chartered practice or an architect registered with the Architects Registration Board. Both are markers of professional standards and ongoing accreditation. It is also worth choosing Bristol architects with direct experience of the city's planning framework, particularly Article 4 directions and conservation areas, which affect a large proportion of Bristol's housing stock. Reviewing project case studies and speaking to past clients will give you a clear sense of whether a practice is the right fit.
-
It depends on the size and type of extension and the specific circumstances of your property. Many extensions fall under permitted development and do not require a formal application. However, Bristol City Council's Article 4 directions remove permitted development rights across large parts of inner Bristol, including many conservation areas. If your property is affected, you will need planning permission even for smaller works. We can check your property quickly and confirm exactly where you stand.
-
Fees vary depending on the scope and complexity of the project. For a residential extension, fees typically cover design, planning drawings and application support. We are transparent about costs from the outset and provide a clear fee proposal before you commit. Our studio is based in Barry, South Wales, which means lower overheads and competitive fees compared with many Bristol-based practices, without any compromise on quality or service.
-
Bristol City Council aims to determine most householder planning applications within 12 weeks of a valid submission. Applications in conservation areas or for more complex commercial projects may take longer. We will give you a realistic programme at the outset and keep you informed throughout the process.
-
Yes. We cover Bristol and the surrounding region including South Gloucestershire, North Somerset, Monmouthshire and the M4 corridor between Bristol and South Wales. We are familiar with the planning policies of Bristol City Council, South Gloucestershire Council and North Somerset Council, and can advise on cross-border projects where multiple authorities are relevant.
-
Yes. Alongside residential work, we deliver commercial architecture for businesses and organisations across Bristol and the South West. Our commercial portfolio includes large-scale industrial and office projects, social housing schemes and community building remodels. Get in touch to discuss your commercial brief.
