Design-led Development

Will Slack Developments extends the architectural vision of Will Slack Design,     focusing on design-led property development across Yorkshire. Led by RIBA chartered architect Will Slack, with over 14 years of bespoke residential design experience, we unlock hidden potential ​and add value to create compelling investment opportunities.

​

We don't just rely on traditional market growth; we create equity through exceptional design. Whether acquiring sites outright or partnering with property owners through Assisted Sales, we unlock the maximum ceiling value of an asset—turning complex, tired, or unviable properties into highly desirable, premium homes.

Our Values

DESIGN

Every project is led by a design-first approach, ensuring quality, functionality, and a strong desirability.

INVESTMENT

Our developments are strategically positioned to deliver strong financial returns for investors, ensuring long-term value and sustainable growth.

VALUE

We go far beyond cosmetic flips. Using over 14 years of architectural expertise, we reconfigure layouts, extend footprints, and unlock hidden density to maximise value.

END USER

Thoughtful layouts and well-considered interiors enhance daily life and are desirable.

Track Record

Our strategy is built on a decade-plus foundation of delivering high-value, complex projects.

What We are Looking For

The types of development opportunities we are looking for across Yorkshire include: 

​

  • Large-Scale Houses: Ripe for spatial reconfiguration or carving into multiple units.

  • Bungalows on Large Plots: Sites with potential for plot redevelopment.

  • Probate & Fixer-Uppers: Unencumbered houses requiring full structural or cosmetic overhaul.

  • Backland & Garden Plots: Parcels of land suitable for infill development.

  • Stale & Hard-to-Sell Listings: Properties sitting on the market that require a creative architectural eye to unlock their value.

 

We are always on the lookout for new development opportunities

and welcome collaborations with investors, property owners, and agents. ​
