Type: Residential
Floor Area: 2,576 m2 
Year: 2017

The scheme occupies brownfield land that forms part of the Greenwich Peninsula Local Development Plan, where it is proposed to evolve this area into a new high quality urban quarter.


The scale of the immediate surroundings is changing, with larger developments being introduced on adjacent sites to the North, where new building heights vary between 7 to 16 storeys. South of the site is predominantly residential, comprising of two and three storey terrace buildings from pre 1900’s.


The client aspiration was to create a modern and attractive residential scheme that would mark the transition of density and scale. The solution should enhance the existing townscape, provide an arrangement of spaces designed to maximize benefits of daylight and sunlight, and incorporate an enjoyable public realm that encourages community engagement and interaction.

A typical house accommodates kitchen and living areas at ground floor, two bedrooms with a shared bathroom at first floor and en suite bedroom with generous terrace at second floor.


In addition to the courtyard, shared, landscaped gardens are also available at ground level.

Taberna do Mercado

Shoreditch, London
Portuguese eatery in East London

Type: Hospitality Interiors
Floor Area: 107 m2
Value: £350K
Year: 2015
Client: Portuguese concepts

Prior to founding Pencilmen Architects, Joao Guedes designed Taberna do Mercado to host the solo project of the Chef Nuno Mendes. The space sits within a listed building inside Old Spitalfields Market, London.

Taberna do Mercado.

Opened by Nuno Mendes in May 2015, Taberna do Mercado attempts to capture and reinterpret Portuguese food and flavours whilst championing specially sourced Portuguese ingredients.


The brief was simple, to create an ambience inspired by the traditional Portuguese tavern whilst promoting Portugal as a brand.

Beyond the cooking, cork tiles clad the bar, marble table tops were shipped from Lisbon to be fitted by a joiner in London, accessories such as the outdoor blankets and candle holders are products from the homeland. The result is a modest and comfortable environment with carefully considered lighting to retain the utilitarian character of the listed building. Unpretentious in its own right, the space is the backdrop for the the real star. Food and wine.

Market Place Revisited

Type: Retail
Site Area: circa 3,000 m2
Value: (undisclosed)
Year: 2017
Client: ELO

OSM is the oldest active market place in London. We are thrilled to have partnered with ELO and produce a feasibility study for refurbishing the iconic market area. The bid was successful and ELO delivered the scheme for Tribeca Holdings with renowned architects Foster and Partners.

The iconic 19th century listed building has adapted throughout time and served many purposes, mostly related with trade of goods. Well known for its bustling market place program, flea markets and the trade of hand crafted goods, the place is much loved by the local community.


The proposal is to upgrade the main trading area, providing better facilities that can trade in all weather conditions. It would also improve the customer experience by adding comfort through heating, lighting, seating and servicing.

Having surveyed the market, it was understood that not every trader requires the same amount of space.


The new stalls would be available in a variety of sizes. The majority of units would be smaller, lighter and moveable to better suit the dynamic mix of seasonal traders. This would provide the space with the precious flexibility to operate additional events. The larger units would be fixed, permanent structures, housing all-year-round uses, these are the anchor units.

We created a layout to provide variety that relates to its surroundings, with anchor units positioned at the main entrances to enhance the sense of arrival, and a central cluster of larger units designed to host carefully curated F&B operators.

The Capital Building is set within the framework of the Terry Farrell and Partners masterplan for the area around the new US embassy, Embassy Gardens.


The circa 150 residential units and roof terraces are distributed between 4 buildings of different heights plus an additional bridge-link building facing the River Thames. All buildings share a raised landscaped courtyard which accommodates car-parking and retail below.

AHMM Capital Building Design Development.

Inspired by late 19th/early 20th-century large masonry buildings in the US, and the American school of Louis Sullivan, the robust buildings express strong vertical lines and accentuated top floors. Situated at the western gateway to the site, these have become a landmark in this new district.

Brentford Waterside

Hounslow, London
Town Centre Regeneration Scheme

Type: Masterplanning
Site Area: 4.79ha
Dwellings: 876 (max)
Density: 203 d/ha
Year: On-going RIBA stage 03
Client: Ballymore Group

Whilst at Allford Hall Monaghan Morris, Pencilmen Architects founder Joao Guedes successfully lead the Hybrid Planning Application of a large regeneration scheme for Brentford Town Center, London.

AHMM Brentford Waterside
AHMM Brentford Waterside.

Brentford Waterside Masterplan is a collaboration between AHMM, Glenn Howells Architects, Maccreanor Lavington and Grant Associates for Ballymore Group.


The proposals establish a high-density, low-rise mixed-use scheme which will revitalise the High Street and create direct links to the River Brent, Grand Union Canal and related waterways.

AHMM Brentford Waterside High Street.

Along the High Street, the scale and grain of the proposals create a strong and well articulated frontage, which accommodate large portions of retail to create an attractive and lively town center. The new frontage is set back from the road to increase pavement widths, include trees and accommodate the cycle superhighway.

To the South, the scheme will make a significant stretch of waterfront accessible and will accommodate several leisure uses. The proposals establish a network of pedestrian routes across the site that will form continuation of the River Thames Path National Trail.

North-south yards echo the historic urban grain, once associated with water related uses. These narrow pedestrian routes are designed to maximise permeability and enhance the incredible potential of the site by linking the main street to the waterfront.

Wellington Row

Type: Residential Refurbishment
Floor Area: 121 m2
Value: (undisclosed)

Located in close proximity to Columbia Road, East London, the new construction  sympathetically refurbishes and extends the rear of the house, positively contributing to the conservation of the historic street scene.


The proposals create additional area and reconfigure the existing layout. Albeit small in scale, the alterations produced impressive results with a very positive impact on the usability of the house, upgrading the old structure to modern standards of living.

The new arrangement creates a larger, brighter and more usable kitchen/dining area and enhance the connection with the garden. The proposed side-return infill extends across the width of the property bringing the disused garden return space into the curtilage of the house.


At first floor, the extension allows for a more efficient use of the space, it accommodates a bathroom and a small study with wardrobe, adding precious storage space for which the property is in much need. In addition to the extension, new rooflights were introduced to bring more light into the first floor, north facing rooms.
