Frequently Asked Questions
How long does a typical London property development project take?
The timeframe depends on the scale and complexity of the project. A single new build home might take 6–9 months from planning approval to completion, while larger multi-unit or conversion projects can extend to 12–18 months. We provide detailed schedules before work begins so you always know what to expect.
Can you help assess if my London property or site is suitable for development?
Yes. We offer site feasibility assessments that evaluate planning potential, access, structural limitations, and market value. This early-stage analysis helps you understand what can be achieved and the likely return on investment before committing to a full design and build contract.
Do I need planning permission for my development?
Most property developments in London require formal planning permission, especially for new builds, conversions, or changes of use. We manage all planning submissions and liaise directly with local councils to ensure your application meets London’s borough-specific requirements.
Can you assist with land acquisition or investment appraisals?
Absolutely. Our team can support landowners, investors, and developers in identifying viable plots and carrying out financial appraisals. We analyse build costs, sales values, and planning constraints to determine whether a site offers good development potential.
What warranties or guarantees come with completed developments?
All completed London developments include structural warranties and a post-completion rectification period. This provides assurance that any issues identified after handover are addressed promptly and professionally.
Do you take on smaller projects or only large-scale developments?
We work across a broad range of project sizes from single property refurbishments and conversions to multi-unit schemes and joint venture developments. Each London project receives the same level of care, quality, and transparent communication.
Can you provide references or examples of past London developments?
Yes. We can share details and images of completed London projects upon request, demonstrating our expertise across new builds, refurbishments, and mixed-use developments. Site visits may also be arranged for serious prospective clients.
