What architectural services do we provide in Northamptonshire?

We specialise in residential design tailored to the local character of Northamptonshire towns and rural villages. Our work spans five core areas:

  • Barn conversions designed to preserve agricultural character while meeting modern thermal standards.
  • Bespoke new build developments and infill housing schemes.
  • Detailed planning applications and drawings for local council submission.
  • Building regulations drawings and construction packages.

How do we handle Northamptonshire planning applications?

Securing planning approval in Northamptonshire requires careful preparation, whether your property sits within a rural conservation village or a modern town settlement. We produce accurate existing and proposed drawings, design statements, and technical details designed to satisfy local planning guidelines. You can learn more about how we assemble comprehensive submissions through our guide to planning applications and drawings.

Rural barn conversions and character properties

Northamptonshire features a rich stock of agricultural outbuildings, traditional ironstone cottages, and historic farmsteads. Converting a rural barn demands a clear understanding of structural constraints, light access, and planning policies such as Class Q permitted development. We work closely with homeowners to retain original timbers and stonework while delivering warm, energy-efficient spaces suited to family life.

Residential extensions and modern family living

For homeowners seeking more room without the expense of moving, residential extensions remain the most practical solution. We design single-storey kitchen diners, two-storey side additions, and wraparound living areas that make the best use of natural light and garden connections. Every layout is developed to fit how your family actually lives.

Support for new build developments

If you have land or an individual building plot, we assist with feasibility, site layout, and full architectural packages for new build developments. We design schemes that respect the surrounding streetscape, address access and overlooking concerns, and present a clear proposal to council planning committees.

Our end-to-end design process

Every project follows our structured five-stage framework to keep progress clear and transparent:

  1. Brief: An initial consultation to understand your ideas, practical needs, and budget targets.
  2. Survey: A precise laser-measured survey of your property and site boundaries.
  3. Design: Developing concept sketches and detailed 2D layouts with your direct feedback.
  4. Planning: Preparing and submitting the planning application directly to your local council.
  5. Aftercare: Supplying building control drawings and remaining available during construction.

Frequently asked questions

Do I need planning permission for a home extension in Northamptonshire?
Certain extensions can be completed under Permitted Development rights if they stay within specific height and boundary limits. However, properties in conservation areas, designated open countryside, or listed buildings often require a full householder planning application. We evaluate your property during our initial survey and advise on the appropriate route.
Can agricultural barns in Northamptonshire be converted into houses?
Yes, agricultural buildings can often be converted to residential homes using Class Q permitted development rights or via full planning permission. Success depends on the structural suitability of the existing building, highway access, and planning designations. We carry out feasibility assessments before developing detailed conversion plans.
Are you chartered architects?
No. Binney & Sims Design is an independent architectural design and planning practice founded in 2013. We are architectural designers specialising in residential extensions, barn conversions, and planning applications, guiding projects from concept drawings through to building regulations approval.
