Derelict Victorian ‘upper parts’ in a town centre location turned in to two very different flats. ### Why is this special? A long unusable set of spaces turned into two sought after flats. All done on a Red Route with nowhere to unload. ### The Challenge This five storey Victorian building close to Putney Station had a café on the ground and basement floor and an unlettable run down single flat on the three upper floors. It needed full renovation inside and out, accessed only via a narrow passage whilst keeping the café open. With no space to extend the other challenge was to fit flats meeting National Space Standards into the existing confined floor plates. ### Our Solution The first floor is notionally a ‘one person studio’, but putting a minimal bedroom and tightly planned shower room at the back left a spacious living room at the front with a high ceiling, period fireplace and three big south facing sash windows. No wonder this flat lets in minutes. Above this is an ‘upside down’ two bedroom duplex with a spacious dual aspect (sunshine one way, view the other) kitchen/ living room making the best of the space in the roof. ### The Results The letting agent called this “the most incredible refurbishment that literally took the property back to the bare walls gave the us the opportunity to create the sort of home you normally only find in expensive lifestyle magazines”. ### Project Details #### Services Provided - full architectural services - concept to completion - outline design - planning permission - construction design and building regulations - tender package - contract administration - site supervision - Health & Safety File - liaise with Estate Agents - provide lease plans and services instructions. - stagging for photos #### Features - Full renovation - self contained flats - upside down duplex - acoustic and fire separation. #### Client #### Year #### Categories Home Renovations Commercial Loft Conversions Conservation & Heritage ## Planning something similar? Straight answers to the questions we're asked most about projects like this one. [Browse all questions](https://www.andrewcatto.co.uk/faq/) We do, and gladly. The discipline of cost control on commercial and development work feeds straight back into our home projects — and what homeowners tell us, in turn, shapes the kind of developments people actually want to live in. Related: [our commercial work](https://www.andrewcatto.co.uk/portfolio/commercial/) Yes. We can take you through every stage — developing the brief, testing what's feasible, the planning application, building regulations and technical drawings, tendering the work, and overseeing the build on site through to completion. Equally, if you only need us for part of the journey — say, to win planning permission — that's fine. Most clients use us end to end, but it's your call. We work closely with clients to understand their budget from the start. With over 1,200 completed projects and 150+ repeat clients, we've developed expertise in designing within budget parameters and suggesting cost-effective alternatives without compromising quality. We provide detailed cost estimates and help manage costs throughout the project. We consider acoustics in our designs, especially for extensions near busy roads or for music rooms. We can specify soundproofing materials and design solutions that minimize noise transmission and create comfortable living environments. Unlike in the recent past, modern flat conversions require effective soundproofing between flats. We have a network of trusted, vetted contractors with proven track records built up over 25+ years in practice. We select contractors based on their experience with similar projects, quality of work, reliability, and competitive pricing. With over 1,200 completed projects, we've established strong relationships that ensure quality delivery. Or we can work with contractors you've already selected. ## Related Projects ![A modern take on the pitched roof-1 - View 1](https://www.andrewcatto.co.uk/api/putney-architecture/media/images/variants/putney-architecture-andrew-catto-architects-lytton-grove-1jpg-a-modern-2fe512a3-1777137141769.jpg/putney-architecture-andrew-catto-architects-lytton-grove-1jpg-a-modern-2fe512a3-1777137141769_tablet.webp) 2025 ### A modern take on the pitched roof [Rusholme Road conservation area - Wandsworth West Hill](https://www.andrewcatto.co.uk/projects/a-modern-take-on-the-pitched-roof/) ![It is not always about a large extensionn - Video](https://www.andrewcatto.co.uk/api/putney-architecture/media/images/variants/putney-architecture-videopostervspfro-4d0a8cec-1775947812593.jpg/putney-architecture-videopostervspfro-4d0a8cec-1775947812593_tablet.webp) 2024 ### It is not always about a large extension [Willett Estate Roehampton SW15](https://www.andrewcatto.co.uk/projects/it-is-not-always-about-a-large-extension/) ![Rear extension that opens to garden - Main view](https://www.andrewcatto.co.uk/api/putney-architecture/media/images/variants/putney-architecture-gallery-42ec55bd-1bd2-4ff9-825b-f41de4f98204-andre-62fe7316-1760993695700.jpg/putney-architecture-gallery-42ec55bd-1bd2-4ff9-825b-f41de4f98204-andre-62fe7316-1760993695700_tablet.webp) 2012 ### Rear extension that opens to garden [Felsham Road- Putney](https://www.andrewcatto.co.uk/projects/rear-extension-that-opens-to-garden/) ## Ready to Start Your Project?
