What you get from ADC

We pride ourselves on the clarity of our drawings and problem-solving architectural design. Lack of space, misuse or under-use of space – these are the problems that we fix. Our design work combines strong aesthetic values with a deep understanding of the skin-and-bones construction of buildings.

After an on-site consultation, we carry out a measured survey and prepare before and after drawings.

Planning Permission

Planning home improvements? Trying to weave through the bureaucratic jungle of Planning Permission?

ADC can help. We have well-established relationships with local councils (Brighton, Worthing, Eastbourne ) and have processed hundreds of planning applications. We understand the system and can help you understand it too.

We provide complete planning permission assistance on all kinds of development, including rooms in the roof (loft conversions), kitchens, bathrooms and garages. This assistance typically covers:

  • Planning Application
  • Drawings
  • Design and Access Statement
  • Heritage Statement (for Listed Buildings and Conservation Areas)

Our approach to Planning Permission is based on experience and a clear understanding of the intention behind the guidelines. Our designs will also lead smoothly into meeting Building Regulations.


Does your house feel cramped – or does it feel like the space is wasted, or misused? Your garden or garage could be key to changing the way you feel about your home, and the way your family fits and lives within the space.

ADC unlock your home’s potential. We design house extensions that provide new living spaces – turning redundant or neglected areas of garden and garage into vibrant rooms you can live in. Get more from your garden by integrating a patio, decking area or conservatory – perfect for entertaining guests.

House extensions also dramatically boost the value of your home. A Nationwide Building Society survey found that house extensions add an average of 12% to the value of a house.

Remedial Building Work

Have you suffered at the hands of bungling builders? Or have time and nature taken their toll?

ADC design repair work to treat:

  • Leaks
  • Damp
  • Cracks
  • Draughts
  • Poor quality or dangerous construction

If you’re disappointed with or concerned about the quality and safety of your building work, let us advise on the best course of action. ADC rethink and re-design construction projects to remedy bad building work. By designing remedial building work, ADC ensure that your solution is professionally constructed.

ADC approach every project with the primary focus on construction that prevents the passage of water, moisture, sound and heat into and out of your home.

Home Refurbishment

There are many ways to improve your home. With a few well-planned adjustments you can achieve a very different ‘feel’ to your rooms. We’re experts at:

  • Creating open-plan areas
  • Using and enhancing natural light
  • Improving glazing shape and size
  • Modernising rooms and fittings

ADC guide you through the process of refurbishment. We suggest the best way to enhance your kitchen, conservatory or living spaces and then communicate these plans to your contractors with annotated drawings.

By planning your refurbishment we add clarity and efficiency to the process – which often produces cost savings.

ADC have refurbished listed buildings and those in conservation areas, which include painstakingly drafting drawings that satisfy strict conservation policies.

Architectural Interior Design

DC design spaces rather than interiors. This means that while we don’t do interior design, we do arrange interior spaces with furniture and fittings in mind. We take your spaces and redesign them according to how you want to use them. We look at human flows through rooms and make efficient use of lighting, electrical layouts and daylight.

We can work with your interior designer (or recommend one) to ensure that our design compliments theirs.

And you can trust that the design of your spaces will comply with Building Regulations.

Permitted Development

Permitted Development is part of building and construction legislation in the UK. Permitted Development allows for some improvements to your house – including extensions, conservatory, loft and garage conversions – to be carried out without the need for planning permission.

Permitted Development often simplifies the building and development process, but care must be taken to ensure that your project falls within the accepted limits. We can guide you through the complexities of Permitted Development and help you achieve a Certificate of Lawfulness.

Loft Conversions

Is your loft an oasis of calm and space, just waiting to be explored? If you want to know if your loft can be converted to a room in the roof, contact us. We have lots of experience of:

  • Loft conversions (or ‘rooms in the roof’)
  • Gable and Mansard roof shapes
  • Dormer and Velux windows
  • Energy efficient development

Make the most of your house – turn unused space into bedrooms, bathrooms, offices and even home cinemas.

Loft conversions also provide the perfect opportunity to improve energy efficiency – so once the conversion is complete you’ll be better insulated and able to reduce your energy bills.

Building Regulations

Okay, so we’ve worked through whether your development is Permitted Development or one requiring Planning Permission, but how is it going to be built?

1:50 scale Building Regulation drawings are required for the construction of:

  • Large conservatories
  • Loft conversions
  • Extensions
  • Garage conversions

With 100% success at gaining Building Regulation Consent, we help your construction project run smoothly.

Our drawings will also be used to communicate your design to the building contractors during the development process. Because of this, it’s essential that your drawings are perfectly accurate and clearly annotated to convey construction details and materials specifications.
