If you are a homeowner in Midhurst considering an extension, a loft conversion or a new build, working within the South Downs National Park planning framework can feel complex. The right residential architectural practice will know this planning environment well, prepare a thorough application and guide you through the process from the first consultation to a decision from the planning authority.
Architecture Surrey provides residential architectural services Midhurst homeowners can rely on, covering the town and the surrounding area. With over 25 years of experience, the practice offers two core services: Extensions & Refurbishments and Residential Building Design. The team works with the South Downs National Park Authority as the local planning authority for this area.

The Planning & Design Service LLP handles every stage of the extensions and refurbishments process for homeowners in Midhurst, from the initial measured survey through to sketch proposals, planning application preparation and submission, building regulations drawings and contractor tender documents. The service covers rear extensions, side extensions, side returns, loft conversions, garage conversions and wider house refurbishments, giving you a complete set of drawings and documents ready for your contractor without the need to manage multiple professionals at each stage.
Midhurst is a historic market town with a varied and often characterful housing stock. The town centre contains a high concentration of listed buildings, including Georgian townhouses, medieval timber-framed properties and stone and brick cottages, many of which sit within the Midhurst Conservation Area. Further out into the surrounding National Park landscape, rural farmhouses, converted barns and more recent detached properties make up much of the stock. Working within the South Downs National Park requires careful attention to design and materials, and a planning application here must demonstrate that the proposed works respect the character of the existing building and its setting.

For clients in Midhurst with a plot of land or a more ambitious residential brief, the Residential Building Design service covers new build properties and larger-scale residential schemes from concept design through to a full planning application and building regulations drawings.
The South Downs National Park Authority sets one of the most demanding planning standards in the South East. New residential development must conserve and enhance the special qualities of the National Park, and design quality is central to any successful application. A carefully prepared and well-evidenced planning application is essential; the practice has experience working within National Park planning environments to give your project the strongest possible foundation.
Planning applications in Midhurst are determined by the South Downs National Park Authority (SDNPA), the statutory planning authority for all land within the National Park. Applications in this part of West Sussex are processed day-to-day by Chichester District Council on the SDNPA’s behalf, but all decisions are assessed against the South Downs Local Plan. Midhurst has a designated Conservation Area covering the historic town centre, which means extensions and alterations within that area are subject to close design review, with particular attention paid to materials, fenestration, scale and the character of the street scene.
Some home extensions in Midhurst may fall within permitted development rights, allowing certain works to proceed without a full planning application, though permitted development is more restricted within the South Downs National Park than in standard planning areas. Even modest alterations may require formal permission. The team advise from the outset whether your project requires a full planning application to the South Downs National Park Authority or a certificate of lawful development, so you always know exactly where you stand.
Every project follows a clear four-stage process, from the first site visit through to a complete set of drawings ready for your contractor.
| Stage 1: Measured Survey | We visit your Midhurst property to carry out a detailed measured survey, giving us the accurate base drawings needed to develop your design. |
| Stage 2: Design & Sketch Proposals | We develop sketch proposals based on your brief, refining the design with you until you are fully satisfied with the scheme before it progresses to a planning application. |
| Stage 3: Planning Application | We prepare and submit your planning application to the South Downs National Park Authority, including all required drawings, documents and supporting information. |
| Stage 4: Building Regulations & Contractor Tender | We produce the full building regulations drawings and, where needed, a tender package to help you appoint a suitable local contractor with confidence. |
The practice covers Midhurst and the surrounding villages and hamlets, including Easebourne, Lodsworth, Stedham, Trotton, Rogate, Elsted and Harting. Postcodes served include GU29. If your village is not listed here, please do get in touch directly; the team are happy to discuss projects across a wider area.
