DIY TIP

So that your deck con­sists of full-width boards, which looks bet­ter and is less work, make the joist length suit your boards. Take the width of each board and add the 4mm gap be­tween them. Mul­ti­ply to find how many boards will fit across your deck. Deduct 35mm from this to al­low for a board along the face of the deck and for the last board to slightly over­hang this. This will give you the length of your deck joists. fit­ted with a metal cut­ting blade to cut them off flush with the timber. STEP 4 Where you want to ex­tend the deck, de­ter­mine po­si­tion of foot­ings and the piers that sit on top to sup­port the bear­ers, which in turn sup­port the joists. If pos­si­ble, use the same timber as the ex­ist­ing so you can eas­ily work out how far the bear­ers and joists will span and the po­si­tion­ing of sup­ports. Dif­fer­ent timber types and sizes re­quire dif­fer­ent lev­els of sup­port. If us­ing dif­fer­ent tim­bers, con­sult a builder or search for span ta­bles to de­ter­mine what is re­quired. STEP 5 Dig 300 x 300 x 200mm deep holes for foot­ings to sup­port bear­ers where re­quired. Mix con­crete, fill holes and let dry. Build 230 x 230mm brick piers on top of foot­ings. Make top of pier be­low ex­ist­ing joists by com­bined height of bear­ers and joists. Leave mor­tar to set.

STEP 6 Sit ant caps on piers then place bear­ers on top.

STEP 7 In­stall joists at each side of deck first. If ex­ist­ing joist is wa­ter dam­aged or screws won’t bite into the timber, in­stall a new joist ad­ja­cent to it and nail the two to­gether. On deck ex­ten­sion, nail through joists into bearer. Run a string­line be­tween th­ese joists along their ends. In­stall re­main­ing joists so their ends meet string­line and nail. Space joists in the ex­tended area of the deck at 450mm cen­tres.

STEP 8 If in­cor­po­rat­ing a step into your deck, as here, cut back the joists where the step will be. Use treated pine sleep­ers as a frame for the step as they can sit di­rectly on the ground. Cut down the sleep­ers to suit the height of your step. Use of­f­cuts of joists for blocks be­tween deck joists and step frame and as fix­ing points for the face board around the step.

STEP 9 Lay first row of deck­ing boards, leav­ing a 4mm gap to the house. Where re­quired, join deck­ing over a joist, cut­ting with a drop saw fit­ted with a fine-toothed blade. Leave a 2mm gap be­tween ends of boards to al­low for ex­pan­sion. At each end of row, use a coun­ter­sink­ing bit to predrill deck­ing then fix to joists us­ing 50mm deck­ing screws. To en­sure the row is straight, run a string­line along edge of deck­ing from each end. Align rest of row to the string­line and then work along it fix­ing to joists.

STEP 10 At each end of first row, mea­sure 564mm (the width of 4 boards and a 4mm gap be­tween each) from edge of boards and mark joists. Stretch a chalk­line to join th­ese points and flick to cre­ate a chalked line along top of joists. Cut and lay an­other 4 rows of boards. Stag­ger joins to avoid cre­at­ing a seam of joins along 1 joist. Fix fifth row to joists so its out­side edge meets chalked line. Space re­main­ing boards us­ing a plas­tic spacer be­tween each row to main­tain an even gap. So your screws are in a straight line, chalk a line along top of boards be­tween screws on first and fifth rows. Fix re­main­ing rows of boards with deck­ing screws along chalked lines. Re­peat to in­stall all deck­ing boards up to end of deck.

STEP 11 Cut and fit face deck­ing along ends of joists for a neat fin­ish. Also cut and in­stall deck­ing to fit along tread and ris­ers of step.

4 Mix up the fo­liage colours and shapes of your pot­ted plants for a more nat­u­ral dis­play.
