Our Story

About DDM

London townhouse

Founded by Dan Gealy

A commitment to excellence in every detail.

Design Develop Maintain was founded by Dan Gealy with a clear and uncompromising vision: to bring a new standard of quality, professionalism, and care to the building and property maintenance industry in Central London.

With extensive experience across all aspects of the building trade — from structural work and carpentry to high-end decorating and project management — Dan built DDM on the principle that every client deserves the same level of attention, regardless of the size of their project.

Operating across Mayfair, Belgravia, Chelsea, Westminster, Fulham and the surrounding areas, DDM has established itself as the trusted partner of choice for homeowners, landlords, and property managers who refuse to compromise on quality.

Our Philosophy

The DDM Approach

Design

Every project begins with a thorough consultation. We listen carefully, ask the right questions, and develop a detailed plan that reflects your vision, your budget, and the character of your property.

Develop

Our experienced team of builders, craftsmen, and specialist tradespeople execute the plan with precision. Our site managers provide daily updates and maintain the highest standards of workmanship throughout.

Maintain

Our relationship with clients does not end at handover. We offer ongoing maintenance packages to protect your investment and ensure your property remains in perfect condition year after year.

Our Standards

Craftsmanship is not a feature — it is our foundation.

We believe that the quality of a building project is determined not just by the materials used, but by the care, skill, and attention to detail applied at every stage. This is why we invest in the very best tradespeople and maintain rigorous quality control throughout every project.

All specialist work is carried out by fully certified professionals. Our electricians are NICEIC registered, our gas engineers are Gas Safe registered, and all structural work is carried out in full compliance with building regulations.
