We had an excellent experience working with Daniel Rainback at Design & Development Associates. Daniel produced an amazing design for our single floor rear extension, creating a beautiful, large open-plan living space with a kitchen and utility room. He truly made maximum use of our space and offered a lot of helpful suggestions we hadn't considered. Communication was top-tier throughout, and we were delighted to receive planning permission so promptly following his submission. Daniel was professional and knowledgeable from start to finish—we would highly recommend Design & Development Associates.

I Have worked with Daniel for many years on varying types of projects both large and small domestic and commercial. He has always been so helpful and has never missed a deadline, some of them very challenging indeed He has a wealth of knowledge that is unrivalled and has become invaluable to our company. Daniel also provides us with a vast array of contacts that help with the difficult planning problems. In an ever frustrating world that we seem to increasingly find ourselves in there is nobody finer to be fighting our corner! I would not use anyone other than him. I value our relationship in the highest regard. MarcPosted on Google Kim BurtonTrustindex verifies that the original source of the review is Google. Daniel came highly recommended to us prior to the design phase of our building project. He worked closely with us as clients to help achieve a stunning design for our home from initial ideas through planning including overcoming hurdles such as tree preservation and bat mitigation. He kept regular contact with our builder and we wouldn't hesitate to recommend him for anyone looking for a friendly, efficient designer. Thanks Daniel.Posted on Google Bradd GTrustindex verifies that the original source of the review is Google. Being a buisness owner operating in the construction industry I first came across daniel and his team whilst working from some of his drawings on a project and must say I was very impressed from the beginning. The drawings and design are always very clear and seem to really make the most of every project, over a number of years I’ve worked from and recommended design and develop to many clients and they’ve never failed to deliver on value and quality always working closely to the clients brief and on budget, so much so I’ve recently used Daniel for a project on my own property which once again turned out fantastic.Posted on Google John GoulbourneTrustindex verifies that the original source of the review is Google. It has been a pleasure to have worked with Daniel throughout what has been a daunting period of both planning and submitting plans to the local authority, and in respect of our single storey extension application. Daniels knowledge has been nothing short of excellent and throughout the process he has guided us through the relevant steps in such a professional manner, and whilst always making himself available for any questions or queries. We highly recommend Daniel to anyone seeking an architect for their own projects.Posted on Google rupert brownTrustindex verifies that the original source of the review is Google.

This architect delivered beyond our expectations, he understood exactly what plans were needed on a medium scale extension. We found Daniel on a local search, He responded to our message immediately. Daniel visited the site and was very friendly and professional in his approach. He created a unique design for our quirky 1930’s bungalow. He guided us through all the procedures of the planning route. Daniel dealt with the local planning office , taking away the stress from us. We would highly recommend him for his professionalism.Verified by TrustindexTrustindex verified badge is the Universal Symbol of Trust.

Frequently Asked Questions
Do I need an architect or architectural designer?
While “architect” is a protected title in the UK, both architects and architectural designers can provide building design, planning applications and construction drawings.
For many home extensions, renovations and new-build projects, an experienced architectural designer can deliver the same practical services at a much more competitive cost.
The most important factor is not the title, but the designer’s experience, portfolio and track record of successful projects. Having completed over 975 projects with a 98% planning approval rate, we believe we can provide a service that exceeds expectations while offering excellent value for money.
How much does an architect cost in the UK?
Architectural fees vary depending on the size, complexity and planning requirements of your project. At Design & Development Associates, we offer a fixed fee service and provide a fully broken-down quotation after your free consultation, so you know exactly what to expect.
Do I legally need an architect for my extension or loft conversion?
You are not legally required to hire an architect for most home projects. However, working with an experienced architectural designer can help you achieve a well-designed, practical space with clear, accurate plans and a stronger chance of planning success.
How long does planning permission take, and how long does it last?
Most UK planning applications take around 8 weeks from validation to decision, although this can vary depending on the council’s workload and whether additional consultations are needed. Once approved, planning permission usually lasts for 3 years.
Can you guarantee planning permission approval?
No architectural designer can guarantee planning approval. However, we design with local planning policies in mind and currently have a 98% approval rating. If amendments are requested by the planning officer, these are included at no extra cost.
I am on a budget, can you help?
Yes. We design with your budget in mind from the beginning and can help obtain build estimates before planning is approved. This allows us to make sensible design tweaks early, helping keep the project aligned with your expectations.
What areas do you cover?
Design & Development Associates provides architectural design services throughout Bournemouth, Poole, Christchurch and the surrounding Dorset area. We regularly work on house extensions, loft conversions and home renovation projects across locations including Canford Cliffs, Parkstone, Southbourne, Talbot Woods, Oakdale, Boscombe and many other surrounding communities.
Why choose a local architectural designer in Bournemouth or Poole?
Working with a local architectural designer means benefiting from experience of the area’s property styles, planning considerations and residential developments. Having completed over 925 projects across Bournemouth, Poole and the wider Dorset area, we understand how to design practical, attractive spaces that work for both homeowners and local planning authorities.
What happens after I contact you?
We will arrange a free on-site consultation to review your project, discuss design options, assess planning requirements and explain the next steps. After the visit, we provide a clear quotation and guide you through the planning and approvals process.
