Cat­ja de Haas Archi­tects looks at archi­tec­ture on all scales: from build­ings, to pieces of fur­ni­ture, art instal­la­tions, urban plans, ideas and con­cepts. We feel that good archi­tec­ture is made when the project is con­sid­ered in its con­text and the right ques­tions are asked in order to come to a bal­anced, orig­i­nal pro­pos­al, that con­forms to the wish­es of the client, while con­sid­er­ing the site. The prof­its made are invest­ed in the run­ning of The Giant Dolls’House Project’, a com­mu­ni­ty arts project that rais­es aware­ness and funds for the impor­tance of a home and com­mu­ni­ty for all.

e-archi­tect fea­tures Burwood

December 2019

We have recent­ly fea­tured on e-architect’s web­site, edit­ed by Isabelle Lomholt. The full fea­ture can be viewed here.

The house has a fab­ric first approach to the design with very low U Val­ues and air leak­age and used Pas­sivhaus detail­ing. The glaz­ing ori­en­ta­tion and build­ing over­hangs pro­mote ben­e­fi­cial solar gains in win­ter, and man­age high solar gains in the sum­mer. A large roof mount­ed pho­to­volta­ic array and elec­tric car charg­ing facil­i­ties and an elec­tri­cal stor­age bat­tery use renew­able energy.

Heat recov­ery from waste air is used to pre­heat incom­ing air dur­ing win­ter. Nat­ur­al ven­ti­la­tion from high and low lev­el open­ings and cen­tral atri­um’ pro­mot­ing stack ven­ti­la­tion forces dur­ing summer.

Bur­wood arti­cle in the Architect’s Journal

November 2019

We are delight­ed that Bur­wood is fea­tured online in the Architect’s Jour­nal, edit­ed by Fran Williams. The full arti­cle can be seen here.

Locat­ed in the south-east of Eng­land in an Area of Out­stand­ing Beau­ty, Bur­wood House con­sists of two oak-clad vol­umes linked togeth­er by a third, inspired by the forms of exist­ing oak trees in the adja­cent gar­den. The large lounge to one side of the house is enclosed by glass and looks out towards the sea. 

Wall­pa­per fea­tures Burwood

October 2019

The full fea­ture Bur­wood is a sus­tain­able tim­ber house’ writ­ten by Ellie Statha­ki for Wall­pa­per can be read here.

Bur­wood is a type of wood that grows in exist­ing woods, becom­ing a new tree’, de Haas explains. It is the name of the house, and we hope the house will itself slow­ly dis­ap­pear in the green.’

Archi­tec­ture Today fea­tures Burwood

September 2019

Archi­tec­ture Today explores Bur­wood as an eco­log­i­cal­ly respon­sive house and the close con­nec­tion it has with it’s coastal site. Full fea­ture here.

Bur­wood is a sus­tain­able four-bed­room house that explores ideas of flex­i­bil­i­ty, inclu­siv­i­ty and scale. Locat­ed in an area of out­stand­ing nat­ur­al beau­ty close to the sea, it com­pris­es two oak-clad vol­umes – that are intend­ed to com­ple­ment the plot’s exist­ing Oak trees – linked by a large glass-enclosed lounge with a grass roof.

Refur­bish­ment of House in Wandsworth

September 2019

Two small bed­rooms on the top floor are sep­a­rat­ed with a cur­tain and have both a small loft room to retreat into. This reduces the height-per­cep­tion of the house and reduces the load on the foun­da­tion. A small dormer hous­es a new small room with views over the city and under the eaves a sec­ond bed­room is locat­ed. The void space is used to hang net­ting in. 

The rafters in the cathe­dral ceil­ing have been left exposed and have been painted.

Third Prize For Hid­den Home­less­ness Com­pe­ti­tion Organ­ised with New Hori­zon Youth Centre
Home­less­ness is still a huge issue, a year after this com­pe­ti­tion was launched and which was won by Mor­ris and co. We will leave this entry as a reminder of the impor­tance of the issue. We do hope to inspire hotel own­ers to incor­po­rate our ideas.

September 2018

Proud to be part of the win­ning team for this impor­tant com­pe­ti­tion. Our pro­pos­al: Good Night’, com­bined a hotel and hos­tel, as a social entre­pre­neur­ship project. Good­night was writ­ten in the para­pet of the pro­posed build­ing: wish­ing all in the build­ing as well as all in the city a good night. We wish each oth­er a good night, every night, a pledge, or reminder that sleep­ing safe­ly is impor­tant: some­thing we should all work towards achiev­ing for all.
