This is a rare opportunity for someone with 2-5 years professional planning experience to gain broad, hands-on experience within a design-led, entrepreneurial developer, where you will take real responsibility and make a visible impact on live projects.

Our client is a fast-growing SME housebuilder based in London, delivering high-quality residential schemes across London and the Home Counties. Their developments typically range from 20 to 100 homes, and they are actively acquiring new sites to support their continued growth.

They believe homes can be beautiful, sustainable and economical. Every scheme they design reflects these values, creating thoughtfully considered places for people to live.

  • Assisting with land appraisals and development feasibility assessments
  • Supporting the preparation and management of planning applications
  • Coordinating with planning consultants, architects and external advisors
  • Conducting site research and policy analysis
  • Monitoring project programmes and key milestones
  • Supporting viability analysis and development reporting

Candidate Requirements

  • Minimum 2 years’ experience in a town planning or development role
  • Strong analytical and numerical skills
  • Excellent written and verbal communication skills
  • Proactive, organised and commercially aware
  • Keen interest in residential development

Working Arrangements

  • Hours: 9:00am – 5:00pm
  • Location: Central London, West End
  • Office attendance: 4 days per week
  • Attire: Business casual

Benefits

  • 25 days’ annual leave plus Bank Holidays
  • Private healthcare
  • 1 additional day of holiday for every 3 years of service (capped at 5 days)
  • Opportunity for long-term progression within a growing business

If you are looking to accelerate your development career within a dynamic and growing London housebuilder, we would love to hear from you.

Please apply here. Our client is looking to find the right candidate as soon as possible - so if in doubt, do get in touch. We also have other clients and roles that may be of interest.
