What Our Clients Say About Us

Highly recommend MM Planning & Architecture
I struggled for over a year to get my double storey side proposal approved without success. After finding MM, Ibbad and Zayn were able to get my proposal approved first time within 2 months! Very professional and experienced team.
Harsh Patel
Fantastic Architects
MM Planning, these guys Ibbad and Elyas are the complete service, very polite, professional and knowledgeable. We had our architectural and structural drawings done, even the build over agreement with Thames Water. They were always available for questions and offered their valuable knowledge throughout our on going project (fantastic).
Daljit Chahal
Professional and Attentive
This review is overdue, but no less heartfelt! We engaged MM Planning & Architecture for some architectural and structural engineering work and dealt mostly with Ibbad. He was incredibly attentive, polite, knowledgeable and responsive throughout the whole period (and beyond)! Ibbad also offered us some good suggestions and ideas outside of our knowledge, which were really helpful.
JBC Crofts
Excellent Service
Ibbad smashed this out of the park! We won planning for a loft conversion with roof terrace. Thrilled with the service that we got. Knowledgeable and sincere communication. Excellent very very happy - see you on the next one Ibbad.
Zayn Malik
Extremely Efficient
MM Planning provided a great services in producing all the drawings and 3D visuals for obtaining planning permission for our Out Building (Permitted Development)and Kitchen Extension (Full Planning). Mr Ibbad was very helpful and knowledgeable with local council procedures and was in regular contact with the planning office. The Out building is now complete and signed off by the council. Many thanks MM planning.
Suraj Natarajan
Incredibly Helpful
Amazing service, truly professional. The work done was to the highest of quality along with the communication from the team to myself and the council being prompt and clear which in turn lead to an immediate approval. Can't thank Ibbad and the rest of your team enough.

📍 Sutton, London

Remember this project? Our client purchased this property in Sutton with an incredible amount of land and a big vision for the future. On a road full of detached homes with stunning extensions, it was clear this house needed a bold transformation to match its surroundings.

But after two planning refusals for so-called
‘overdevelopment’—a decision we found baffling given the clear improvement to the home and street scene—we decided to fight back. And we’re thrilled to share that we won the appeal!

Sometimes councils just don’t get it, but persistence pays off. Here’s to turning dreams into reality, one project at a time!

📍Purley, London. 

Sometimes, even with so much already in place, there’s a lingering thought: What could elevate this further? For this client, the answer was clear—a refined front transformation utilising the untapped potential of their roof space. Tasked with reimagining the upper floors, we crafted a thoughtful internal redesign that seamlessly integrated an elegant staircase into the loft. This was achieved by ingeniously adapting the existing staircase layout and introducing a central bay window to bring balance and character.

The front elevation now boasts two charming cottage dormers, each providing ample headroom to accommodate a luxurious bathroom and a bespoke walk-in wardrobe. At the rear, a carefully proportioned box dormer sits subtly within the original roofline, ensuring it remains harmonious with the property’s character. This rear addition forms a spacious lounge area, part of an opulent master bedroom suite entirely nestled within the newly optimised roof space—a perfect blend of style, functionality, and architectural finesse.

📍 Wandsworth, London.

Swipe right to the end to see how this property has been transformed. 

This property went through a major reconstruction phase. We carried out a 6m rear extension; full gut out and major remodelling of the ground floor to create a formal living area, large family bathroom tucked in between the new open plan kitchen/dining area and the front reception room. A utility room/pantry. The first floor was mainly refurbished along with the addition of a new stair case into the loft area for the master suite which included a walk-in wardrobe and an ensuite. It’s a shame we can’t fit the entire project into one gallery but the rest of the photos will follow when the client can fully move in.
