Development Summary.
A Landmark Development Opportunity
Horlers are delighted to present an outstanding freehold residential development opportunity, with full planning permission for the construction of three brand new executive homes, offered to the market at an asking price of £900,000
This is an exceptionally rare chance to acquire a genuinely ready to build scheme, with detailed planning consent already secured, comprehensive architectural drawings prepared, and the benefit of a successful planning appeal. Opportunities offering this level of certainty, preparation and immediate deliverability are becoming increasingly scarce.
The approved scheme provides for approximately 516.35 sq m (5,558 sq ft) of gross internal accommodation across the three homes. This figure includes the fully habitable second-floor loft accommodation, which benefits from sufficient head height and forms an integral part of the living space. All marketing will therefore reflect the full gross internal area, ensuring the accommodation is represented accurately and to its fullest extent.
Designed with both practicality and profitability in mind, the development has been carefully considered to maximise build efficiency whilst creating three highly desirable family homes. The architecture is clean, elegant and uncomplicated, with the buildings rising directly from the footprint without unnecessary rear projections or structural complexity. The only enhanced detailing is concentrated on the principal elevations, delivering strong kerb appeal without compromising construction efficiency or build costs.
Unlike many development sites, this is not a speculative land sale. The development is approached via a private road serving existing residents, and as such we are seeking an experienced, financially secure developer with a proven reputation for delivering high-quality projects in a considerate and professional manner. The expectation is for a well-managed construction programme, with minimal disruption throughout the anticipated twelve-month build period.
From a developer's perspective, the site offers an exceptional combination of advantages:
• Flat and easily developable site
• No demolition costs or associated delays
• Services already available to the site boundary
• No requirement to construct a bellmouth or undertake highway alterations
• No excavation of the public highway for drainage or service connections
• Secure, enclosed and easily managed site
• Full detailed planning permission already granted
• No lengthy access road infrastructure required
• Straightforward, efficient construction design reducing build complexity and programme risk
In today's market, opportunities combining planning certainty, build simplicity, minimal abnormal costs and immediate deliverability are increasingly difficult to find. This scheme offers exactly that, presenting developers with the opportunity to commence works quickly while maintaining confidence in programme, cost control and eventual marketability.
For further information, including the full planning pack, architectural drawings and planning decision notice, please contact Horlers. We would be delighted to discuss this exceptional opportunity in greater detail.
