Backyard Oasis Design in Southeastern Pennsylvania

The best backyards are not a pool here and a patio there. They are one space, designed together, that feels like a private resort. Blue Tree designs and builds complete backyard oases, pool, patio, kitchen, fire, planting, and lighting, as a single coordinated project. For 43 years, our team has transformed properties across Southeastern Pennsylvania.

What Sets Blue Tree's Backyard Oasis Design Apart

Most backyards get built in pieces by different companies that never talk, and it shows. Blue Tree designs the whole oasis at once, so the pool, hardscape, outdoor kitchen, fire feature, planting, drainage, and lighting all work as one. A single designer owns the vision, one team builds it, and grades, materials, and sight lines line up because they were planned together. This is the work Blue Tree was built for, with pool construction, ICPI-certified hardscape, and landscape design all in-house. Blue Tree has built complete backyards across Montgomery, Bucks, Chester, Delaware, Lehigh, Berks, and Philadelphia Counties since 1983.

Our Backyard Oasis Process, Step by Step

From the first site visit to the final walkthrough, one designer and one team build your entire backyard. Here is how it comes together.

Step 1: Free On-Site Consultation

A Blue Tree designer walks your property and listens to the big picture: how you want the backyard to feel and function, from swimming and entertaining to quiet evenings. We read grade, drainage, sun, and access, and talk budget and phasing. The visit is free with no same-day pressure. Timeline: 1 visit, about 90 minutes.

Step 2: Custom Design and 3D Renderings

Your designer plans the entire oasis, pool, hardscape, kitchen, fire, planting, and lighting, as one layout, then you review 3D renderings of the finished backyard with your house in frame and refine everything on screen before construction. Timeline: 3 to 6 weeks.

Step 3: Materials, Proposal, and Permitting

Blue Tree specifies every material and feature, prices the project as one itemized proposal, and handles township permits, impervious-surface calculations, and engineering in-house. You see the whole plan and cost before you sign, and projects can be phased. Timeline: 4 to 10 weeks, varies by township.

Step 4: Professional Installation

One team builds the entire oasis in a coordinated sequence: pool, hardscape on a proper base, kitchen and fire, drainage, planting, and lighting. Because the same company does it all, the trades line up and the grades match. Timeline: several weeks to a few months, varies by scope.

Step 5: Aftercare & Warranty

Blue Tree starts up the pool, tests every feature, and walks the finished backyard with you. You leave with all warranty terms in writing, including the lifetime structural warranty on the pool shell, and ongoing care is available through Premier Outdoor Services. Timeline: a few days.

What a Backyard Oasis Brings Together

Built for Southeastern Pennsylvania's Land and Seasons

A complete backyard has to work with everything Southeastern Pennsylvania throws at it: clay soil, freeze-thaw winters, heavy storms, and township impervious-surface limits that cap how much hardscape and pool a property can add. Blue Tree designs the whole oasis around those realities, with engineered bases, real drainage, and in-house permitting, so the finished backyard holds up for decades. The team has built complete outdoor spaces across Montgomery, Bucks, Chester, Delaware, Lehigh, Berks, and Philadelphia Counties since 1983.

Common Questions

Complete backyard projects from Blue Tree that combine a pool, patio, outdoor kitchen, fire, planting, and lighting typically run from about $150,000 to $400,000 or more, as of 2026, depending on the pool, materials, and features. Many homeowners phase the work over time. Every project starts with a free consultation and an itemized proposal, so you see the full plan and cost up front.

Yes, and it is common. Blue Tree designs the entire backyard as one master plan, then builds it in phases that fit your budget and timeline, often starting with the pool and core patio and adding the kitchen, fire, planting, and lighting later. Because the whole thing is designed up front, the phases fit together instead of fighting each other.

Because the alternative is a pool company, a hardscape contractor, and a landscaper who never coordinate, leaving you to manage the gaps and the grades that do not match. Blue Tree designs and builds the pool, hardscape, and landscape in-house, so one designer owns the vision and one team delivers it. That is the single biggest reason the finished backyard looks intentional.

From design to a finished backyard, a complete oasis usually takes several months, including permitting, the pool build, hardscape, and planting. The pool and hardscape are the longest phases. Your designer builds and manages the schedule, sequences the trades, and keeps you updated at every stage.

Yes. A complete backyard often involves pool permits, electrical, impervious-surface calculations, and sometimes engineering for walls. Blue Tree handles all of it in-house, which is a major advantage of using one company, because the approvals are coordinated rather than chased across three contractors.
