About us

Martin Sewell started his West Sussex-based building company following a five-year engineering apprenticeship with the global electronics brand, Phillips Research. With a strong family background in construction, there was an ideal support network in place with many vital skills being handed down from Martin’s father.

Taking care to ask incisive questions, having a professional insistence for thoroughness, great attention to detail and consistently high standards, steady growth was, and continues to be, ensured. Martin Sewell Building Company projects range from modest, domestic requirements to major design-and-build projects for a variety of private customers, a hospital, private schools, high profile architects and local authorities in and around West Sussex. (See Case Histories).

Our three critical principles:

  • Good management is absolutely crucial for most successful projects.
  • A professional and experienced partner will ensure a high-quality finished product.
  • More often than not, the least expensive materials and services do not equate to the best value – false economy.

About you

If there is one thing The Martin Sewell Building Company has learnt about building projects, it is that almost every project is a prototype. Your house has never before been built, renovated, or extended in quite the way you intend. Of course, a very large percentage of the methods, details and techniques involved in construction are replicated thousands of times on a daily basis but the small percentage that makes your project unique requires a large skill set of experience, communication and ‘know how’ to be utilised successfully.
